 PLASTIC FILLING, AND THE BASAL PRINCIPLES OF 
 THE NEW DEPARTURE. 
 
 BY J. FOSTER FLAGG, D.D.S., OF PHILADELPHIA. 
 
 f New York Odontological Society. 
 
 \ Special Meeting, November ZQth and zist, 1877. 
 
 The Society was called to order at 8 o'clock, P. M., November 2oth, 
 Dr. A. L. Northrop, President, in the chair. The essayist of the even- 
 ing, Dr. J. Foster Flagg, of Philadelphia, spoke as follows : 
 
 MR. PRESIDENT, AND GENTLEMEN OF THE ODONTOLOGICAL SOCIETY 
 OF NEW YORK : I wish to thank you from the very bottom of my heart 
 for the invitation you have extended to me to speak to you this even- 
 ing. I wish you to understand that I distinctly appreciate the honor 
 which you have conferred upon me by giving me more than ten times 
 the usual limit given to one who speaks before you. Furthermore, 
 gentlemen, I know that you are well aware that I have much to 
 present to you which is out of the ordinary course of communications 
 to dental societies. But, gentlemen, you don't know half what a 
 heretic I am ! and as I think of the work before me I feel like a 
 modern Daniel in a large-sized lion's den ! I feel like an insignificant 
 David before a full-sized Goliath; but as Daniel came out of the lion's 
 den, and as Goliath went down before David, so I expect to get out 
 unharmed, and so I expect Goliath to go down ! 
 
 I have come here to-night to sling the first stone not that I expect 
 to hit him in the forehead not that I by any means expect to kill 
 him to-night, for he will die hard ; but I do expect that strength will 
 be given me to deal him a good, hard blow. 
 
 That which I bring you to-night is no growth of a day. It is no work 
 of a year. I therefore recognize that what seems to me to sound as it 
 ought to sound, will sound to you just as it ought not to sound. I shall 
 present to you the time-honored and ordinarily "accepted creed " 
 of dentistry, and I shall advocate before you the diametrically antago- 
 nistic "creed of the New Departure." Do you suppose it is a new 
 thing for me to be antagonizing accepted dentistry ? No, gentlemen, 
 it is no new thing. For more than twenty years I have not known 
 what it is to be upon the " right side."

 2 PLASTIC FILLING AND THE BASAL PRINCIPLES 
 
 Twenty years ago, my very good and highly esteemed friend, Prof. 
 Robert Arthur, enunciated his belief in leaving decay in the cavities 
 of teeth, and filling over it, for a wise and special purpose, as he 
 thought, and it was stigmatized as nasty, dirty, slouchy work ; and our 
 " great man," Prof. J. D. White, said that "when he could not spend 
 time to properly clean out the cavities he would retire from practice." 
 Here is a document written by my honored father's own hand, giving 
 an account of the action of a college faculty on the question : " When 
 the faculty of the old college met for the purpose of arranging the last 
 ' Announcement ' of that school, exception was taken by Prof. White 
 to what he considered as ' false doctrine ' on the part of Prof. 
 Arthur in regard to two prominent features in our art, both of which 
 may be considered of vital importance to our success as instructors, 
 and to the successful practice of many of our graduates. The first of 
 these was, that Prof. Arthur advocated the leaving of caries in the 
 cavity of a tooth and plugging thereon ; and the second, deemed 
 equally objectionable, that of using ' sponge gold ' as a material for 
 filling teeth, and as a substitute for gold foil. Now, although every other 
 member of the faculty fully coincided with Prof. White in his opposition 
 to this practice of Prof . Arthur" etc., etc. 
 
 How many professors of to-day oppose the " leaving of decay and 
 the plugging thereon " when the pulp would be exposed by its re- 
 moval ? How many? I ask ! // is now the accepted practice ; and yet, 
 only twenty little years ago, it was so heretical and such " false doc- 
 trine," that the entire faculty "coincided with Prof. White; "and 
 Dr. Louis Jack and Dr. J. Foster Flagg were the only two men of the 
 forty-five hundred dentists of the United States that immediately ac- 
 cepted Prof. Arthur's practice, and from that day to this have sys- 
 tematically left decay in every cavity where its removal would expose 
 a living pulp. Thus you see it is no new thing for me to question the 
 creed of the profession. I became used to it when I was young, and 
 it has grown with my growth. 
 
 Years have rolled on, and, as you know, without much attendance 
 on my part at dental meetings ; but do you suppose I have been doing 
 nothing ? Far from it. Day by day I have filled tooth after tooth, 
 and have marked what I have done. Year by year I have tabulated 
 results until they now amount to thousands upon thousands. Letters, 
 by the score, have passed between Syracuse, St. Louis and Phila- 
 delphia. At length I wrote to my friends, Drs. Palmer and Chase, 
 that I felt we were as ready now as ever we should be. 
 
 Gentlemen, we believe that we have for our "New Departure," 
 grand, basal, foundation principles, which have so grown with us that 
 they already seem as old and as solid as the hills. I don't come to 
 say hard words to you;. I don't come to retort upon you for the
 
 OF THE NEW DEPARTURE. 3 
 
 language which some of you have used towards us. You who have 
 said it know what you have said ; but I come to ask, that/r<?;# this 
 time on, as we have spoken out our belief, as we shall speak out our 
 " creed," you will let us believe without saying hard things of us. 
 
 If you have any good arguments against our position, we are as 
 anxious to hear them as you can possibly be to present them ; but if 
 you continue to say "plastering in amalgam," we could retort by 
 saying, ' punching and poking and pounding in gold," because we 
 know that is the way it is done. But we also know that it cannot be 
 well done in any other way ; nor can plastic fillings be well put in 
 without "plastering." It is the way to do it; and is not "plaster- 
 ing" quite as agreeable as "pounding?" We call your "punching 
 and pounding " the introducing of the filling, and we wish you to call 
 our " plastering " the introducing of our fillings. 
 
 More than twenty years ago, Prof. Elisha Townsend gave to his co- 
 temporaries the assertion that he "saw daily the undeniable evidence 
 of the fact that teeth could be saved with amalgam, which he could 
 not save with gold." His memory is revered by us all. As a worker 
 in gold he was unsurpassed. As a proof of his estimation of plastic 
 filling, he gave to his profession "Townsend's Amalgam," that ma- 
 terial with which we began our labors, that material which had so 
 much of good in it that we were more and more impelled, as the years 
 passed by, to recognize its value. 
 
 I feel that I owe much to Prof. Townsend, for he made the way of 
 experiment easy for me. Within a very short time after his death, 
 nearly two hundred of his families became my patients. This not only 
 placed me (then a beginner in Philadelphia) at once in full practice, 
 but enabled me to cultivate a ground for plastic filling which had 
 been well broken by one in whom they had unbounded confidence. 
 Now, gentlemen, the statistics which I propose to offer to-night have " 
 been based upon this experience. 
 
 ARTICLE I. Accepted Creed : Gold is the BEST thing to save teeth. 
 
 ARTICLE I. New Departure : In proportion as teeth need saving, gold 
 is the WORST material to use. 
 
 Gentlemen, I am, for the moment, literally but a mouth-piece. Dr. 
 Chase has spoken to you. This article is his. He was the first who 
 had the hardihood to say that "in proportion as teeth need saving, 
 gold is the worst material to use." This he said, and Dr. S. B. Palmer 
 and I fully endorse that which he has spoken. 
 
 Mark my words ! This is a real belief which I am speaking to you. 
 Men are coming to our belief every day the thinking men, the ob- 
 serving men of dentistry. They write me that they introduce their 
 beautiful jewels of gold with the view of their premature wreck staring
 
 4 PLASTIC FILLING AND THE BASAL PRINCIPLES 
 
 them in the face ! That with their very best, and long-continued 
 effort, they are unable to save teeth as they would, with gold. 
 
 And is this nothing ? Can a man continue to work, and put 
 " piece after piece " in proper place when he feels that the work is 
 killing the patient and himself too, and that when a few short years 
 shall have passed away, his work will be good for nothing ? 
 
 This is what sapped me fifteen years ago. I had been filling teeth 
 then for fifteen years. I can show you plenty of plugs of gold not 
 twenty or thirty but hundreds, that I introduced more than 
 twenty-five years since, and which are just as good to day as on the 
 day when they were done. But these were in strong teeth, in places 
 easy and accessible, in teeth that might have gone but little had they 
 been left unfilled ; while of the others, of the teeth that needed 
 saving, -I can but tell you just what all have seen. One by one 
 these teeth came back to me. Day by day I saw my best efforts 
 going to destruction. I heard that my work must be defective ; but 
 I felt that there might be something lacking in the material. 
 
 And then, there were the first of my statistics. It is more than 
 twenty years since this work was begun. Twenty-two years ago I 
 made five hundred fillings. Two hundred and fifty were of gold, 
 just as the cavities came in practice, the next two hundred and fifty 
 were filled with tin, gutta percha and amalgam, the amalgam taking 
 the brunt of the battle, and used in places that were too far gone for 
 any other thing. I then waited for five years, watching the progress of 
 events, and meanwhile returning to orthodox practice. At the end 
 of this time I was not satisfied, and I waited another year. It was to 
 be a life-work with me. I could not do it over again. Nor can I. I 
 have done. 
 
 At the end of that time the "undeniable evidence " presented itself 
 to my mind. I felt the truth of what Dr. Townsend had said, and 
 came solidly to the belief that / could save teeth with amalgam which 
 I could not save with -gold; for, already in the soft teeth, in the 
 inaccessible places, in the cavities under the gum and with frail 
 walls, the gold fillings were becoming defective ; while the plastic 
 fillings, far, far better held their own. 
 
 To-day, gentlemen, the " efforts" in gold which formed that trial- 
 band have almost passed away ; and still quite a number of the plastic 
 fillings, some even of the most hopeless cases, are pointed to with 
 pride, and satisfaction by their owners. 
 
 Seventeen years ago I began the systematic introduction of six per 
 cent, of plastic fillings, choosing, of course, those places best adapted 
 for them that is, the worst. The next year I introduced twelve per 
 cent. ; the next, eighteen per cent. ; and, year by year, results were 
 such as warranted this progression. You can readily see where this
 
 OF THE NEW DEPARTURE. 5 
 
 ends. This is my seventeenth year, and I should have put in one 
 hundred and two plastic fillings in every one hundred. I found 
 myself not equal to the emergency ! 
 
 I stand before you with a practice which I have been sixteen years 
 in arranging. I have taken the refuse teeth from all directions ; 
 announcing, from year to year, to my patients, that I desired the teeth 
 that were ordinarily extracted, and that I was fast abandoning artifi- 
 cial work, because I felt that I could do my patients better service by 
 repairing wrecks and building crowns on roots. The result is, that I 
 have many mouths in which the tteth have proven themselves wretched 
 beyond wretchedness, yet these all are comfortable. I have teeth by 
 the hundreds such as melt (for they have melted) from gold, like 
 snow before the sun, at the hands of our very best operators. 
 
 For all this heap of seeming impossibility, I use nothing but plastic 
 fillings. Once in a while I use ////, because I am engaged on a series 
 of experiments to find the action of this metal on dentine. Our filling 
 materials are, gutta percha, amalgam, and oxy-chloride of zinc (so- 
 called). With these I do everything. All this in the mouths of the 
 very best class of patients. 
 
 "In proportion as teeth need saving, gold is the worst material to 
 use." This point alone takes in the whole of Palmer's electro chemi- 
 cal theory of the action of filling materials: but I must tell you what 
 the work of winnowing out the chaff, as far as we could do it, has 
 eliminated. 
 
 The work has been done by Prof. Henry Morton, of Hoboken, and 
 Prof. Snyder, of Philadelphia, scientists ; Messrs. Eckfeldt and Du 
 Bois, assayers of the Philadelphia Mint, metallurgists; and Drs. 
 Palmer, Chase, and Flagg, dentists. 
 
 We have carefully, and, we believe, scientifically, investigated every 
 line of experiment which has professed to show the current which, we 
 believe, is eliminated by contact of metal with tooth-bone. This we 
 have done with the best instruments and apparatus which our country 
 can produce and we find that such current has never been shown, 
 much less measured. Even that curiously ingenious line of experi- 
 mentation, upon this subject, which was presented at the "Centen- 
 nial " meeting of the American Dental Association and which gave 
 to our profession that scale of relativity known as the " Harvard Ten- 
 sion Series," in which gutta percha was placed at "o"and gold at 
 " 200," and which gave those who had faith in gold, such " a black 
 eye" (as it was expressed) we pronounce utterly worthless and with- 
 out any scientific basis. And yet, I will read you Prof. Morton's 
 opinion of that electro-chemical theory upon which we rest our belief 
 as expressed in this Article I. ; for, if gold is the worst material to use, 
 there must be some scientific reason for it.
 
 6 PLASTIC FILLING AND THE BASAL PRINCIPLES 
 
 After speaking of the great difficulty of current elimination, Prof. 
 Morton says, " On the other hand, we have the best reason for 
 assuming on analogy and authority that all chemical action invokes 
 electric disturbance. Now acid fluids do act chemically on bone, and 
 the presence of a good conductor, which is itself unattacked, in con- 
 tact, must, on general electrical principles, assist the electro-chemical 
 action. Supported by your facts of observation, and the reasonable- 
 ness and consistency of the electric theory, you may well rest your 
 case there. But it is, of course, very important not to give your 
 opponents a chance to attack by resting, for a proof of your theory, 
 on experiments which are themselves unsound and capable of confuta- 
 tion." 
 
 Now you see, gentlemen, that notwithstanding the fact that we are 
 unable, as yet, to demonstrate the existence of the current, yet never- 
 theless, the "reasonableness" and "consistency" of our theory is 
 such that we may say that gold, being a good conductor, and being 
 itself unattacked, when placed in contact with tooth-bone, must on 
 general principles cause excessive electro-chemical action, which 
 action must eventuate in disintegration of tooth-tissue ; and, there- 
 fore, gold is the worst material to use, when a tooth is of such 
 structure and in such condition as that it needs something which 
 will help to preserve it. 
 
 The stereotyped answer to this is couched in these few words, " If 
 gold is so put in as that no fluid can come between it and the tooth, 
 bone, there will be no chemical action ; because, where there is no 
 fluid there cannot be any chemical action." Then, gentlemen, why 
 don't you put it in so? If you cannot, then use something else, if for 
 no other reason. 
 
 ARTICLE II. Accepted Creed ': Either " contour filling" or "sepa- 
 rating teeth ' ' is the best method to arrest decay. 
 
 ARTICLE II. New Departure: Neither "'contouring filling" nor 
 "separating teeth " has much to do with the arrest of decay. 
 
 For years the discussion between contour and separation has gone 
 on. With Arthur, Bonwill and Chupein, for the A, B, C, of the 
 separationists, and Atkinson and Webb as representatives of the whole 
 alphabetic list of contourists, (Atkinson even building Mansard roofs 
 for the comfortable occupancy of the tooth spirits] and yet no definite 
 decision has ever been reached. Now it seems to us that if either was, 
 in truth, decidedly the right way, it would have been found out by 
 this time. 
 
 In regard to this contest, we have been lookers-on, and our statistics 
 do not yet show us which is best. Contour fillings fail, and fillings 
 in separations fail; and when the contours fail, it is said, "It
 
 OF THE NEW DEPARTURE. 7 
 
 ought to have been separated " ; and when the fillings in the separa 
 tions fail, it is said, " The separation is not made rightly." Mean- 
 while, the teeth decay. 
 
 For me, in a strong, solid tooth, I would, for durability, just as 
 soon make a contour filling as I would a separation ; but on general 
 principles, and for comfort, I prefer to give my patients the benefit of 
 what is called contour. My experience is that they are better than 
 the separations, certainly on the score of comfort, and probably on 
 the score of durability. 
 
 ARTICLE III. Accepted Creed, Failure in operations is mainly due to 
 defective manipulation. 
 
 ARTICLE III. New Departure. Failure in operations is mainly due to 
 incompatibility of filling material with tooth bone. 
 
 When I say to you that " failure in operations is mainly due to de- 
 fective manipulation " does it not sound as though I was teaching 
 orthodox doctrine to young men ? 
 
 We have striven to strengthen our efforts and to make them more 
 serviceable and acceptable to our patients by devising and using fill- 
 ing materials "compatible with tooth bone," but you are constantly 
 told that " Excelsior " is the word ! 
 
 Did any of you ever hear that expression at a dental meeting? 
 Did you ever hear any gentleman wind up a glowing peroration on 
 " fine work," "perfect manipulation," ''conquering of all difficul- 
 ties," and " final glorious results" with "Excelsior! Gentlemen, 
 Excelsior is the word ! " Now what is this " Excelsior" business? 
 It appears there was a young man climbing a mountain with a little 
 banner over his shoulder He saw " nice, warm fires in happy homes" 
 and they made him "groan!" A worthy, reliable old gentleman 
 warned him against going further but it was of no use, up he went ! 
 A maiden requested him to "stop and rest his weary head upon her 
 breast ;" and, do you believe it ? the fool wouldn't even stop for 
 that and the end of it was that a dog found him dead in the snow ! 
 
 Not any " Excelsior " for me ! 
 
 But thus it is, all the elegant fillers, high style $75, $150, $500, 
 plug men tell you that failures are due to defective manipulation. 
 Now, gentlemen, if this is so, why don't you manipulate better ? Sim- 
 ply because you cannot. And is it nothing against gold that men 
 cannot manipulate it ? Is it nothing that this has been proven by an 
 experience of more than half a century ? The record of to-day is not 
 better than the record of fifty years ago. You talk about the "finer 
 work," the "improvement in foil," the " improvement in instrumen- 
 tation," the " blessed rubber dam," but with all these adjuncts, while 
 you have put all these gifts to tests which have proven their greatest
 
 8 PLASTIC FILLING AND THE BASAL PRINCIPLES 
 
 capability, your results are, larger fillings, more difficult fillings, more 
 tedious fillings, more painful fillings, more expensive fillings, less 
 compensating fillings (both to yourselves and patients), and more 
 decided failures. I state this squarely. For every one of these large, 
 difficult, tedious, painful and expensive fillings that have given a 
 dozen years of service, I think you will acknowledge that I am within 
 bounds when I say a dozen have proved failures. 
 
 My statistics show that the average of gold failures for the last year 
 is greater than for any previous year. One hundred gold failures were 
 classified upon my tables last year, for the whole twelve months ; and 
 this year, up to this month, I have already 86, making a total for 
 1877 of 103 ; many of them far worse failures. This is the truth. 
 This shows what attempts are being made, and what failures are the 
 results. 
 
 It was only on last Friday morning that I renewed (by guarding) a 
 gold filling which had been introduced less than three years before, 
 into a cavity upon the mesial face of the right upper second bicuspid, 
 with the first bicuspid out. I want you to think of this, and note the 
 exceeding difficulty (?) of the original operation. The patient, Mr. 
 J. W., one of our largest car- wheel manufacturers, told me he paid $20 
 for the filling ; and I showed him that I could pass a broad, thin in- 
 strument deep into the crevice between the filling and the tooth, at 
 almost any point. I told him that I could not say of such beautiful 
 work, what I believed the gentleman who did it, would say of it, viz. : 
 that it must have been defective in manipulation; but that I knew just 
 how soft his teeth were (he had formerly been my patient,) and that I 
 believed the failure was due to incompatibility of gold with tooth bone. 
 
 NOTE. Since making the remarks and drawing the deductions (which are cor- 
 rectly published in the " Dental and Oral Science Magazine") in relation to this 
 case, I have been informed by my patient that it was not the $20 filling which had 
 failed, and that it had been introduced three years and three months instead of " less 
 than three years." 
 
 But while I eagerly embrace this opportunity to correct these errors, I would say 
 that I could have cited plenty of cases which would have been in principle precisely 
 as I represented this one, which was naturally first remembered in consequence of 
 its recent reparation. 
 
 We believe that "failure in operations is mainly due to incompatibili- 
 ty of filling material with tooth bone." This again opens all the ques- 
 tion upon which rests our vitality. When I tell you that experimentally, 
 the contact of gold and bone, amalgam and bone, tin and bone, and 
 gutta percha and bone, results, again and again, in greatest loss of 
 substance in that bone which is in apposition with the gold, I say,
 
 OF THE NEW DEPARTURE. 9 
 
 " he that hath eyes to see, let him see ; and he that hath ears to hear, 
 let him hear." And when I see just the same thing occurring in the 
 mouth, every day that I practice, and then read that " experiments 
 out of the mouth must be taken for nothing !" I cannot but feel that 
 such writers are "straining at gnats," while their patients are "swal- 
 lowing camels." 
 
 ARTICLE IV. Accepted Creed : A tooth that is worth filling at all, is 
 worth filling with gold. 
 
 ARTICLE IV. New Departure : A tooth that can be so treated as to 
 be satisfactorily filled with anything, is worth filling. 
 
 The fourth article of the accepted creed and its twin brother " a 
 tooth that can be filled at all, can be filled with gold," seem to me 
 such perfect puerility that I have no patience with them. This latter 
 enunciation is from our good friend Taft's last work on Dentistry, 
 "up to the present status of the profession," the preface says. The 
 scathing criticism of this production in the " Cosmos" induced me 
 to examine more closely than I might otherwise have done, this effort 
 of Dr. Taft's. Among things like " vacuums " between pulp-caps and 
 pulps, I found this statement, that "a tooth that is worth filling at all, 
 is worth filling with gold." It is also enunciated that " a tooth that 
 can be filled at all, can be filled with gold." So can a man walk from 
 here to Broadway on his hands ! but it is not generally regarded as 
 the best way to do it ! 
 
 Neither is it the best thing always to fill any tooth that can be filled, 
 with gold. It is not the best, the most acceptable, the most expedi- 
 tious, or the most comfortable way to do. // is not the most servicea- 
 ble way to do. I assert that experience proves this ; but beyond that, 
 I most emphatically deny both assertions. I deny that "a tooth which 
 cannot be serviceably filled with gold, is not worth filling." I deny 
 that "any tooth which can be filled at all, can be filled with gold." 
 No one, not even the most expert, can fill with gold every tooth that 
 can be filled. How much less, then, can the average, respectable 
 practitioners of dentistry do this thing ? You may get gold into it, 
 after a fashion, but you cannot fill it, according to your own ideal of 
 what a filling should be. 
 
 On the other hand, with a plastic filling material it can be filled, 
 and filled nicely, and so as to be comfortable and serviceable for many 
 years. Experience has shown this. The profession, and the coming 
 text-books, when they are truly "up to the status of the profession," 
 will admit it. Therefore we say that " a tooth that can be so treated, 
 as to be satisfactorily filled with anything, is worth filling."
 
 10 PLASTIC FILLING AND THE BASAL PRINCIPLES 
 
 ARTICLE V. Accepted Creed: Unskilled and unscrupulous dentists 
 fill with tin covered with gold, THEREBY causing galvanic action, pulpitis, 
 death of the pulp, abscess, d#</LOSS OF THE TOOTH. 
 
 ARTICLE V. New Departure : Skillful and scrupulous dentists fill 
 with tin covered with gold, THEREBY preventing decay and pulpitis and 
 
 THEREBY SAVING THE TOOTH. 
 
 "Unskilled" and "unscrupulous" these are not nice words to 
 use, and yet these are the words which, having been spoken and 
 printed in relation to our practice, compel us to use the phrase "skill- 
 ful and scrupulous" and that is just what we mean if it is skillful, 
 to work out the experimental saving of teeth which in ordinary prac- 
 tice are lost and, on the other hand, if it is not scrupulous to meet 
 the indications more completely than had been done, and to continue 
 efforts in despite of the insinuations that the tin was used because of its 
 cheapness / and the gold as a means of hiding the deception ! then I 
 do not know what " scrupulous " means ! 
 
 Experience had proven that tin would save teeth which gold did 
 not. The accepted belief was, and is, that it did so because of its 
 softness, and ease of manipulation, (for which qualities, by the way, 
 we have never heard it decried). Our belief now is, that it saves 
 teeth because of its low conductivity, and because /'/ is itself attacked. 
 Experience had also proven that the tin wore out ; and so, the happy 
 combination which would save the tooth and yet not wear out, having 
 been devised, it was decried and defamed as unskillful and unscru- 
 pulous. 
 
 Fifteen years ago this was the accepted practice of my office. It is 
 because of this principle that the operation of "guarding" with a 
 crescentic guard of tin, amalgam, or gutta-percha at the "vulnerable 
 spot" has retained failing gold plugs, by the hundred, for continued 
 usefulness. I, myself, had, up to April, 1877, 1053 gold plugs, of my 
 own, and many other operators', doing service only because they had 
 been " guarded " in this way. Gold doing well because it was taken 
 fare 0/by tin, gutta-percha, or amalgam ! the white troops victorious, 
 because the colored troops fought bravely ! a pretty picture. 
 
 ARTICLE VI. Accepted Creed : A filling, to be good, MUST NOT LEAK. 
 
 ARTICLE VI. New Departure : A filling may be the BEST that is 
 known for the tooth, AND YET LEAK BADLY. 
 
 How do we maintain this point ? We hold that this is true be- 
 cause of the fact that gutta-percha makes a leaky filling. See this fill- 
 ing in this tube; every care was taken that it should not leak. It was 
 packed even better than it could have been in a tooth, and yet, as you 
 see, "it leaks badly. But you will say, that a glass tube is not analogous 
 to a tooth. I am prepared for that. Here are small cups of ivory.
 
 OF THE NEW DEPARTURE. II 
 
 This material is almost identical with that of tooth bone These were 
 filled, as you see, the one with red gutta-percha, and the other with 
 Johnston's Premium Stopping; and yet both leak. 
 
 Why do we maintain it ? We do so from the fact that we wish 
 to make it a basal principle, that mere leakage, itself, is not the thing 
 which makes a filling capable or incapable of saving a tooth. It de- 
 pends upon what material leaks, and what it leaks in contact with. If 
 a leak of vitiated saliva occurs between tooth bone and a material 
 which is a good conductor and is itself unattached, then that leaky filling 
 is very bad. But if even vitiated saliva leaks between tooth bone 
 and a material which is, practically, a non-conductor, and which has 
 a surface that is neither bright nor oxidizable, then leakage is proven 
 by experience to be not practically detrimental. This we hold to be 
 the reason why gold fillings " eat themselves out " of soft teeth in from 
 two to five years ; and why gutta-percha remains untouched (except 
 by attrition), and preserves such teeth for many, many years. 
 
 ARTICLE VII. Accepted Creed : Gutta-percha, PROPERLY USED, is good 
 enough for TEMPORARY fillings. 
 
 ARTICLE VII. New Departure : Gutta-percha, PROPERLY USED, is 
 the MOST PERMANENT filling material we possess. 
 
 When my friend, Dr. Hawes, was in my office for a part of two 
 days, some months ago, I operated before him. Among other patients 
 was a young lady from Orange, New Jersey. I showed him a line of 
 several gutta-percha fillings, in front teeth, which had been intro- 
 duced seven years before. I showed him a gutta-percha filling in the 
 buccal face of a left lower molar, which he thought was " somewhat 
 cupped," and would "hardly pass for a permanent filling." The 
 patient informed him that it had been doing service for twenty or 
 twenty-one years ! and I added, that if it lasted as much longer I 
 should mark it down as permanent. 
 
 Twenty-six years ago, Dr. G., of Philadelphia, came to my father, 
 desiring his services. My father introduced eleven gold fillings, 
 good, old-fashioned, solid, "straight from the shoulder" fillings. 
 Beside these cavities there were four enormous places in the four 
 wisdom-teeth, (poor teeth, according to "accepted" views), and these 
 were filled, "experimentally;" three with amalgam, and one (the 
 buccal face of the right lower wisdom), with gutta-percha, with the 
 idea that they might " last for a year or two." The last one of the 
 eleven gold fillings was renewed a few months since, and the three 
 amalgam fillings, and the gutta-percha filling, are still preserving their 
 forlorn and worthless wisdom-teeth, as they have done, for more than 
 a quarter of a century ! 
 
 These are not isolated cases. They are, far more, typical cases. I
 
 12 PLASTIC FILLING AND THE BASAL PRINCIPLES 
 
 have, in the mouths of my patients, hundreds upon hundreds of gutta- 
 percha fillings, which have been doing service for from five to fifteen 
 years, and bid fair to continue so doing for years to come. 
 
 Gentlemen, I feel, when I introduce a gutta-percha filling into a 
 large cavity on the buccal, mesial, or distal face of a tooth, close to- 
 the gum, with frail walls, and almost into the pulp, as though I had 
 done something. I feel that I have (if it be possible) saved that tooth 
 and pulp, that I have placed there a material, which, even if it be 
 gradually softened and worn out, will save the tooth until the last thin 
 stratum, only, still remains. I feel that if it wears, an easy, inexpen- 
 sive reparation can be effected, by the addition of a little more of the 
 same material at any time. I feel that I have done my patient that 
 real service which he or she had hoped to have bestowed. 
 
 This is why we say that " gutta-percha, properly used, is the most 
 permanent filling material we possess." 
 
 ARTICLE VIII. Accepted Creed : A GOOD gutta-percha filling, IN ITS 
 PROPER PLACE, is better than a POOR gold one. 
 
 ARTICLE VIII. New Departure. : A POQR gutta percha filling, IN ITS 
 PROPER PLACE, is better than a GOOD gold one. 
 
 This seems almost like a joke ! but we have introduced this as an 
 "emphatic," and we mean just what we say. 
 
 Some time ago, a few of our Philadelphia gentlemen saw themselves 
 on paper as saying almost too much in favor of gutta-percha ; so they 
 corrected it by publishing that they did not mean to say that gutta- 
 percha was as good as gold : what they meant was, " that a real good 
 gutta-percha filling, in its proper place, was better than a poor gold 
 one." Meanwhile, cases such as this were coming to our notice. Mr. 
 J. G. W. had a gold filling introduced upon the mesial face of the left 
 upper lateral, by one of our best operators. In about two years the 
 filling failed. It was renewed, and in less than two years this second 
 filling failed. We think we have a right to infer that both these fill- 
 ings were good ones. Upon the occasion of a third visit, a gutta- 
 percha filling was hastily introduced, to serve merely, as was stated, a 
 temporary purpose. While yet the filling was in place, the gentle- 
 man's partner (a patient of mine) induced him to call upon me. I 
 was told the story. I examined the gutta-percha filling. It bore evi- 
 dence of its hasty insertion, having overhanging edges. These I 
 trimmed with a warm instrument, and asked him to give me the first 
 proof of his confidence in his partner's recommendation and my judg- 
 ment by allowing the gutta-percha filling to remain, as it was a proper 
 place for it. Already that filling has lasted longer than either of the 
 gold ones, and, from appearances, it will last far longer than both the 
 gold ones together.
 
 OF THE NEW DEPARTURE. 13 
 
 This is also not an isolated case, and it is from such instances as 
 these that we deduce " that a poor gutta-percha filling, in its proper 
 place, is better than a /?</ gold one !" 
 
 ARTICLE IX. Accepted Creed : Amalgam, PER SE, is a VWR filling 
 material. 
 
 ARTICLE IX. New Departure: Amalgam, PER SE, is an EXCELLENT 
 filling material. 
 
 I do not mean to say that all you gentlemen think or say that amal- 
 gam is a poor filling material. But I do mean that this is the teaching 
 of the most recent and accepted text-books and authorities. Read 
 Taft, pages 93, 94 and 95, and you will see the "creed " of "Ann 
 Arbor" and "Ohio." 
 
 I am truly thankful, for the sake of conservative dentistry that such 
 teachings are hemmed in on the West by St. Louis ! and on the East 
 by Syracuse and Philadelphia ! and for the whole matter of the three 
 pages devoted to the discussion of amalgam, I assure you, gentlemen, 
 it is entirely NOT so ! Not but that the author believes what he has 
 written, not but that he conscientiously believes every word of it. 
 But from the washing of the mass in " boiling water" who ever heard 
 of such a thing f much more, who ever saw it done ? to the final state- 
 ment that " the cohesive property of gold renders this metal equal in 
 adaptability to amalgam "(!) it is practically all NOT so. Read it, 
 gentlemen, read it, and don't believe it ! "Amalgam, per se, is an 
 excellent filling material." 
 
 Nevertheless, I do not wish you to think for a moment, that we regara 
 amalgam as the ULTIMA THULE. By no means. While we recognize its 
 great excellence, we also recognize its great deficiencies. 
 
 The relative durability of the three materials, gutta percha, 
 amalgam, and gold, is a question which I have been engaged upon for 
 more than fifteen years ; during which period I have endeavored to 
 tabulate this matter by following the career of over twenty thousand 
 fillings. Of course, I recognize the impossibility of doing this with 
 scientific accuracy. I admit that my result is merely a guess ; but, 
 gentlemen, I regard it as a very close guess, that as the result of aver- 
 age dentistry, gold fails in fifteen years in seventy-one per cent, of its 
 cases, and amalgam in fifty-four per cent, of its cases. Understand 
 me, this is average dentistry. It is not poor dentistry, for the gold 
 efforts of such, you know, would not nearly reach such a standard. 
 Neither is it truly "first-class" dentistry. If it were, I should be 
 ashamed of first-class dentistry. But it is very close to what our Pro- 
 fession, as a Profession, is doing for those of humanity at large who 
 come to us for services.
 
 14 PLASTIC FILLING AND THE BASAL PRINCIPLES 
 
 Now when you reflect that all the good places, all the easy places, 
 all the accessible places, as a rule (admitting all exceptions) are filled 
 with gold ; and that all the bad places, all the hard places, all the 
 " forlornities," as a rule (admitting the exceptions) are filled with 
 amalgam, we think that it does not tell so badly for amalgam, while 
 we say for the gold, that it is a pity that it is so incompatible with 
 tooth-bone. 
 
 For gutta-percha, with two thousand fillings of an average duration 
 of eight years, (these were in carefully selected places, but all in soft 
 teeth) the failure is but eight per cent. One hundred and sixty fail- 
 ures in soft teeth, in two thousand cases, in eight years. These 
 failures were mostly from disintegration of the gutta-percha. The 
 action of the fluids of some mouths causes this material to soften, puff 
 up, and disintegrate. In such mouths gold is almost worthless for the 
 average practitioner, except upon the articulating faces of the teeth ; 
 and, in these mouths, tin and amalgam have proved themselves our 
 most reliable filling materials. 
 
 But you will say that gutta-percha fillings do not ordinarily last that 
 way. That is because they are put in definitely, only as temporary 
 work, being removed in a short time to be replaced with work which 
 is called permanent. The gutta-percha is almost always found (no 
 matter how long it has been allowed to remain), preserving the tooth 
 perfectly ; and is frequently complimented by the operator for having 
 done so, even while he is introducing his permanent filling, which, 
 in truth, has often to be renewed sooner than would have been the 
 case had he allowed his temporary filling to have remained. 
 
 Again, your instructions as to working gutta-percha, from the 
 directions to "heat it on a porcelain or metal slab over a spirit-lamp," 
 (there is no surer method of ruining the material from over-heating) 
 to the "holding of an instrument on the filling, and pressing it till it 
 is cool"; these instructions, I think, amount to nothing. Take a 
 cavity on a lower second molar, first molar and wisdom tooth in place. 
 The cavity shall begin on the mesial face, and deeply circumscribe 
 the tooth, close to and partially under the gum, until it has passed 
 along the buccal and distal faces and impinged a little on the lingual 
 face. There is a place to fill ! You all have seen such places, and 
 they are excellent to fill with gutta percha. 
 
 I have often listened to good friend Atkinson, as, with streams of 
 intelligence scintillating from his flashing eyes, and his whole coun- 
 tenance beaming with enthusiasm, he would expatiate on the wonder- 
 ful workings of the mallet in the " hands of intelligence." But I tell 
 you, gentlemen, it would take no less than four instruments in the 
 hands of four intelligences to press in such a plug till it got cold !

 ARTICLE X. Accepted Creed : The use of "plastic" filling materials 
 tends to lower the standard of Dentistry, thereby diminishing its sphere 
 of usefulness. 
 
 ARTICLE X. New Departure : The use of " plastic" filling materials 
 tends to lower that Dentistry which has for its standard of excellence 
 " ability to make gold fillings" but very much extends the sphere of use- 
 fulness of that Dentistry which has for its standard of excellence 
 "ABILITY TO SAVE TEETH." 
 
 This is where we rest our case. It is for the salvation of teeth that I 
 have come to speak to you to-night. I have spoken only with that 
 end in view. I don't wish to speak of good, strong teeth. I don't 
 wish, at this time, to tell you of my practice of to-day, what I am 
 experimenting on, what I am tabulating. I have come only to tell 
 you what I have done, and what conclusions I have arrived at, as the 
 result of experience and long years of practice. 
 
 But I do not wish to say anything to you of the teeth which you 
 are in the habit of filling successfully, and, as we express it, satisfac- 
 torily, with gold ; teeth of dense structure, whose cavities have walls 
 so strong that you can impact a filling which lasts a lifetime. But I 
 do ask that you will gradually discontinue this packing of gold into 
 teeth that are so poor, so frail, so unsubstantial that it is, to say the 
 least, doubtful whether the result will be creditable to your pro- 
 fession, or satisfactory to your patients. 
 
 Commence, if you will, with those poorer and more miserable teeth 
 which you would condemn to the forceps, and fill them with plastic 
 fillings. I desire that you shall do it well just as your trained hands 
 can do it after you have learned. Take this just as I mean it, gentle- 
 men, for, is it not "reasonable" and "consistent" that if you had 
 filled largely with plastic materials and but little with gold, you would 
 not fill to the best advantage with gold ; therefore, as you have filled 
 largely with gold, and but little, comparatively, with plastic materials 
 you will not, at first, fill to the best advantage with plastics. But you 
 will soon be agreeably impressed with your results in the new direc- 
 tion. You will soon find that much which has been told you by 
 tradition and text books has no reality in it. It is true that our results 
 are produced more easily, comfortably and economically to the pa- 
 tients, but they will not complain of that. It is also true that our 
 results are produced with greater ease to the operator ; and, for this 
 reason, it is argued by our opponents that we do it from " laziness." 
 
 But I tell you, that it is not from laziness. It is from a desire to 
 lay aside the forceps. It is from a desire that our patients shall eat 
 upon teeth, the roots of which, at least, are in their jaws. It is from
 
 1 6 PLASTIC FILLING AND THE BASAL PRINCIPLES 
 
 a desire that they shall be exempt from the infliction of artificial work. 
 It is from a desire to extend the blessings which the hand of our pro- 
 fession holds to bestow. It is that we may be sought, rather than 
 avoided, that we may be extolled rather than decried, that we may be 
 esteemed rather than censured, that rather than be feared, we may be 
 loved and respected. It is for this that I have worked ; and blessed 
 be God ! that He has so sustained and directed me that I have, every 
 day, fresh cause to believe that I have gained the love of my patients, 
 and the respect of my professional brethren ! 
 
 And now, I find on the programme " Incidents of Practice." I 
 supposed it meant "incidents of my practice, " and so I have come 
 prepared with a few to offer you ! 
 
 Since twelve years ago (July 1865) I have been keeping the money 
 record of five sets of teeth, among the softest and frailest of those 
 under my charge. These were poor enough ; decayed through and 
 through, so that you could string five or six in a row ; broken off, 
 decayed down to and under the gum. From 1865 to 1877 (twelve 
 years) these teeth have been kept, comfortably, in order. Not one 
 tooth has been lost from the five mouths, during all this time. That 
 alone, is something ; but in adding up the aggregate of all their bills, 
 and dividing the total by five, it shows that those mouths have been 
 kept in order for less than $15 each per year ($14.80). This brings 
 dentistry within the reach of many who have heretofore been deprived 
 of its benefits. It brings it where it belongs, to be a blessing to the 
 millions ; and this is why we say that our "practice " very much ex- 
 tends the sphere of usefulness of that dentistry which has for its 
 standard of excellence "ability to save teeth." 
 
 Prof. J. G. Richardson had in 1869 a right upper lateral, right upper 
 central, and left upper central decayed and needing saving. The 
 lateral and left central were filled with gold ; but the right central, 
 being much worse than either of the others, my advice was asked in 
 regard to it before it was filled. I said that it would be best to fill it with 
 gutta-percha. "What! a front tooth?" was the reply. "Why, yes! 
 why not ?" said I ; " a man wants to save his front tooth just as much 
 as he would a back one !" So it was filled with gutta-percha. In a few 
 months from that time the lateral ached so badly during an entire night, 
 that, in the morning (I think it was on Sunday I was not in the city), 
 he called upon a dentist and insisted that it should be extracted. 
 In the course of time an ominous shadow passed over the left cen- 
 tral, which told that its pulp had quietly died a natural death. It was 
 entered, the pulp removed, and it is now doing good service as a pulp- 
 less tooth. But the worst of the three, the one that in 1869 most 
 needed saving, has been saved, and is, to-day, a living, healthy, brilliant

 tooth. I saw it but a few days since. The filling is a little worn. I 
 have an appointment with him, to add a little gutta percha to it, on 
 my return ; when, with fifteen minutes' work, I shall start it off for 
 another eight or ten years' journey. 
 
 Mrs. McG., left upper lateral: In this tooth two gold fillings, one 
 5, the other $6, lasted fifteen years. By the failure of both the tooth 
 had become pretty badly decayed. Twelve years ago a gutta-percha 
 filling was introduced for $4. With two trifling repairs so trifling 
 as to cost nothing, that filling has preserved the tooth perfectly. 
 
 Mrs. B., eleven years ago, had a range of gutta-percha fillings intro- 
 duced by a gentleman in Germantown. Her teeth were very frail. 
 The fillings cost $25. In about two years, while visiting one of our 
 Philadelphia gentlemen, she mentioned that it was about two years 
 since she had had any work done. She requested an examination, 
 and was told, very emphatically, that there was some great mistake, 
 that there was nothing but temporary work in her mouth, and that she 
 ought not to have any other than the very best, which was gold work. 
 Rather shocked at what she heard, she immediately made appoint- 
 ments, and had over $150 worth of gold fillings introduced. 
 
 All the gutta-percha fillings were removed and replaced with gold, 
 except one poor molar; which was stated to be "worth nothing ex- 
 cept gutta-percha." In about two years from that time she visited 
 my office at the recommendation of a friend, when I found every gold 
 filling in such condition that my friend, Dr. Dixon, would have 
 thought proper to have them removed. I said to her that the mistake 
 had been made of filling her teeth with gold, when they ought to have 
 been filled with gutta-percha; and, showing her the poor molar, said, 
 "Do you see, this poorest of all the teeth has been filled with gutta- 
 percha, and it is the only one that is not very defective." 
 
 Her eyes filled with tears as she told me the story of her four years' 
 experience ; and, as she finished, she asked what she should do. I 
 suggested that she should call on and show the gentleman who did the 
 gold work the result of his labors. This proposition being declined 
 with a show of considerable spirit, I then suggested that she should 
 let the first gentleman replace the defective fillings with gutta-percha, 
 as he had had the good judgment to do it in the first place. She said 
 that he was in Florida, and would not be back until some months 
 later, and then asked if I would fill them with gutta-percha. I did 
 so ; and some three years after (she had gone to the far West), I heard 
 that all was comfortable and doing well. 
 
 Just $200 for $25 worth of work ! as one practical experience of 
 gold fillings in soft teeth ! 
 
 Dr. S. has three daughters. The eldest had centrals and laterals filled 
 with gold at nine years of age. These fillings failed and were renewed
 
 1 8 PLASTIC FILLING AND THE BASAL PRINCIPLES 
 
 when she was eleven. Again they failed, and at thirteen and fourteen 
 years of age they were severally renewed. Under these fillings the 
 pulps died, and the teeth came to me for treatment. She has four 
 discolored, pulpless teeth. 
 
 The teeth (centrals and laterals) of the second daughter were filled 
 when she was nine with malleted fillings. At eleven they failed, when" 
 hand pressure fillings were introduced. These failed when she was 
 between thirteen and fourteen, and gutta-percha fillings were then 
 introduced. At sixteen these are good, and all the pulps are vital. 
 
 The centrals and laterals of the third daughter were filled with 
 gutta-percha when she was nine. She is now twelve, and all the 
 fillings are just as they were when introduced. 
 
 These are typical cases of my gutta-percha results. Now for 
 amalgam. 
 
 Mr. D., the great umbrella manufacturer of our city, came to me in 
 1859 with a left upper molar. It had been pronounced unworthy of 
 salvation, and he desired ether as an anaesthetic. I suggested that it 
 would be a very great loss to him, and proposed treating it and build- 
 ing on an amalgam crown. This was done, and to-day he calls it his 
 "veteran ;" and it has enlisted many a new recruit into my army of 
 teeth "not worth saving!" 
 
 Mr. C. W. came to me in 1857, with no teeth to spare. He was in 
 young middle life (twenty-seven or eight), and had already lost many 
 teeth. The tooth he came to have extracted was filled then with 
 amalgam. He broke the crown off a few weeks since. I show it to 
 you here. The roots have a full amalgam crown built on them now, 
 of " Eckfeldt & Du Bo is' Standard Alloy." 
 
 Since 1857 I have a list of a few over 500 patients who have come 
 to me having lost already what teeth they could comfortably spare ; 
 and from all these mouths, since that time, not one tooth has been 
 extracted. Can any of you do any better than that with your $40 
 gold fillings? 
 
 Now I have here three teeth which I have brought you on the 
 discoloration question. I would have brought more, but unfortunately 
 the patients are eating on them! This one was in service 15 years ; 
 this one for 17 years; and this one for 22 years. Do you see that 
 these teeth are not one particle discolored? These fillings are made of 
 Townsend's Amalgam, which contains only tin and silver. When 
 such fillings leak sufficiently, the tooth becomes discolored, just as 
 teeth become discolored when gold fillings leak ; but so long as they 
 are tight, and in teeth of average quality as to structure, then discolo- 
 ration is the rare exception, rather than the rule. I tell you, let an 
 average operator introduce into one hundred average teeth, fifty fill- 
 ings of gold and fifty fillings of amalgam, and in ten years there will
 
 OF THE NEW DEPARTURE. 19 
 
 not only be more of the amalgam fillings doing good service, but 
 among the fillings that are left, there will be found more discoloration 
 around the gold fillings than are around those of amalgam. This is a 
 startling statement, at least to some of you ; but I assure you that I do 
 not make it loosely, but as the result of long and careful watching, 
 as the result of many years of patient observation. Try it, those of 
 you who doubt, and see for yourselves. For me, I am far beyond 
 trying this now. I practice solidly upon this belief every day. 
 
 Again, your ideas of amalgam are based almost exclusively upon its 
 workings in the enormous cavities of almost completely abandoned 
 teeth. You select teeth that, you say, are " worthy of nothing else." 
 Now is this fair ? For if amalgam will save such teeth even doubtfully 
 well and exceptionally, is it not worthy a trial in some of the moderately 
 sized cavities of teeth of somewhat better structure, where, even yet, 
 gold occasionally fails ? 
 
 It was said on one occasion, by my very good friend Dr. Bogue, 
 that he " viewed with admiration the pin-head cavities in centrals 
 filled with amalgam by Dr. Clowes." Now I have viewed, I think, 
 a great deal more frequently, with not so much admiration, the enor- 
 mous cavities in centrals which had become so (I say this advisedly) 
 as the result of two or three consecutive gold fillings in each. For 
 me, I would rather have one of Dr. Clowes' "pin-head" amalgam 
 fillings in one of my centrals, than to have one of those evidences of 
 "first-class ability" such as carried death to the pulps of both cen- 
 trals and laterals of the young lady whose case I have related to you 
 this evening. 
 
 Nor, gentlemen, is this any unusual story of "accepted " dentistry. 
 Front teeth, par excellence, are filled and refilled with gold, as the 
 best that can be done, until pulp after pulp dies, tooth after tooth be- 
 comes discolored and crumbles away, root after root is extracted, 
 and plate after plate is inserted. This is stereotyped practice, and I 
 defy contradiction of the statement. 
 
 / think that a liberal allowance of gutta-percha and amalgam fillings 
 in these very teeth, while yet the cavities are only pin-head cavities, 
 would be a step in advance of this ! 
 
 This is still talk /'/ makes quiet but it is what I have come to- 
 night to say. 
 
 Now, gentlemen, I want to tell you one thing more which has 
 grown out of our Plastic Fillings, that we have not come before you 
 prepared for only a small struggle. We are prepared for the fight. 
 We feel that we have plenty of shot in the locker. We have opened 
 our batteries against the accepted dentistry of the day. We are an 
 aggressive party, and we purpose insisting that our "Basal Principles" 
 shall be thoroughly discussed. We purpose making it respectable that
 
 2O PLASTIC FILLING AND THE NEW DEPARTURE. 
 
 teeth shall be filled with materials that experience has shown to be 
 able to save them ; and we purpose making it not respectable to fill 
 teeth with materials that experience proves daily to be " unequal to 
 the emergency." 
 
 Gentlemen, I have brought up thirteen hundred patients from child- 
 hood ; and from the whole thirteen hundred mouths but five perma- 
 nent teeth have been extracted, and these five teeth I hare as the 
 trophies of my success: not to show that my "scalps" are many, but 
 to glory that they are so few. I do not say this to you boastfully. I 
 could not do that, for my heart is too full of earnest, deep-seated 
 thankfulness that it has been given to me to go in that path which 
 has led to so much comfort for so many of my fellow-creatures. But 
 I must plead guilty to a feeling of the intensest satisfaction as I think 
 of the fact that every one of mine eat upon full, unbroken arches, 
 above and below ! 
 
 Gentlemen, make a beginning with the teeth you would extract, 
 and treat them. Make that dentistry. Fill them with plastic fillings; 
 and if, in twenty years, your experience shall have been that which 
 mine has been, you will thank that great and excellent dentist, Elisha 
 Townsend, as I thank him, for having had the hardihood to break 
 the trammels of tradition and authority in declaring that "teeth 
 could be saved with amalgam which he could not save with gold." 
 
 And now, as in conclusion I again thank you for having listened to 
 my long effort, how vividly comes to my mind the parable of the 
 sower and the seed I feel that I have been sowing the seed to-night 
 some has fallen by the wayside and the birds have already picked it 
 up some has fallen upon stony ground and will spring up quickly, 
 but having little earth it will soon wither away some will fall among 
 tares, and the tares will grow up and choke it but I have faith to 
 believe that yet some has fallen upon good ground, and that in due 
 time, this will bring forth fruit, some thirty, some sixty-fold, and some 
 an hundred.

 The New York Odontological Society held its regular meeting on 
 Tuesday evening, April loth, 1888, in the parlors of the New York 
 Academy of Medicine, No. 13 West Thirty-first street. 
 
 The President, Dr. J. Morgan Howe, in the chair. 
 
 The President. We will now pass to the consideration of the subject 
 of the evening: 
 
 "METALS AND OTHER MATERIALS FOR FILLING TEETH." 
 
 This is intended to include a discussion of the subjects of gutta- 
 percha and amalgam, and especially the papers of Drs. Flagg and 
 Bonwill, which there was not time to discuss at their reading. As Dr. 
 Flagg's paper was the more recent and is fresher in our minds, we will 
 consider that and the subject of gutta-percha first. I will ask Dr. Payne 
 to favor us with what he has to say on the subject ot gutta-percha. 
 
 Dr. E. T. Payne. The address delivered at our last meeting by 
 Prof. Flagg would have been more profitable, it appears to me, if his 
 remarks had been formulated for a paper which could have been read 
 in forty minutes or one hour. Members could then have asked ques- 
 tions and brought out points which would have been instructive, and, 
 I am inclined to think, more profitable than the protracted talk. 
 
 After eliminating the cavities where the speaker said gutta-percha 
 was not indicated as a desirable filling for permanency, there can be 
 no controversy as to its being the most permanent and useful filling for 
 the class of cavities selected for its use. It confirms the judgment 
 of men of experience nothing more. Prof. Flagg distinctly said he 
 did not want the material looked upon as a crutch to help us over diffi- 
 cult places, and spoke disparagingly of Dr. Atkinson, who had recom- 
 mended it in that relation. His teaching in respect to this point will 
 not be accepted by those practitioners who have kept sensitive, low- 
 toned teeth quiet and comfortable with gutta-percha until something 
 more permanent could be used. If young men do accept such teaching 
 they will deny themselves a great help to usefulness. 
 
 I heartily indorse all that was said about using steam heat in pre- 
 paring the filling for the cavity, and the heating of instruments also. 
 Too much care cannot be taken in this matter. Heating any gutta- 
 percha stopping over the flame of a lamp is bad practice, and gene- 
 rally results in more or less injury to the filling. Dr. Hill once told 
 me he was convinced comparatively few dentists used gutta-percha in 
 such a way as to obtain the best result. My experience induces me 
 to indorse what he said so many years ago. 
 
 Regarding the longevity of gutta-percha fillings, I want to say that
 
 undoubtedly it is true that in a few instances fillings made of gutta- 
 percha remained in teeth twenty years or more. Prof. Flagg left it a 
 fair inference that the same result would obtain now if the case was 
 favorable and a good quality of gutta-percha was properly used. The 
 inference is misleading and untrue. 
 
 In a paper on gutta-percha read before this society four years ago, I 
 stated that the gum obtained by cutting the tree and scraping the inside 
 of the bark was much superior to any obtained by tapping. It is to 
 that superior quality of gum which Dr. Hill used the first years of his 
 experience that the results so much talked about are due. The speci- 
 mens displayed by the speaker, both the crude and that which was 
 prepared for the teeth, are the product of tapping. Fillings made in 
 the best manner with such material will not last longer than from two 
 to eight years. Very few, indeed, will last more than four. Let us not 
 deceive ourselves. It cannot be depended upon as formerly. The reason 
 is the inferiority of the base A fountain does not rise above its source. 
 
 I object to the speaker's position in claiming so much for the material. 
 It is very useful, and the cause is weakened by claiming too much. 
 Young practitioners should be taught these facts instead of accepting 
 the fair inference from Professor Flagg's remarks that if his steam-made 
 stopping is used all will go well for from five to thirty years. His state- 
 ment that red gutta-percha shrinks more than any other may be proved 
 by test-tubes, but my experience proves that it will last longer than the 
 average stopping. One reason is it has less foreign substance incorpo- 
 rated into it. Pure gum would outlast any other, and if it coald be 
 used to advantage, it would be almost perfect as to its lasting qualities. 
 Its color, however, is objectionable. 
 
 I repeat what I said in my paper four years ago, that, just in pro- 
 portion as the particles are separated by a "foreign substance, just in 
 that proportion is the substance weakened both in strength and in 
 ability to resist the fluids of the mouth 
 
 We were told by Prof. Flagg that it is our duty to test the material 
 before using it, as one can do so in a few minutes in his office. A little 
 farther on we are told that so difficult is an analysis of the material 
 that it is not known positively what substance Hill incorporated with 
 his base. His statement that Hill's formula is unknown, because he 
 did not happen to know it, is suggestive and amusing, to say the least. 
 There was no intimation that gutta-percha stopping was not in every 
 way as good now as it was twenty-five or thirty years ago when Hill 
 and Bevans were using the gum before referred to. He knew, of 
 course, that the best stopping in the market to-day is very much inferior 
 to the article which gave the filling material its deservedly high repu-
 
 tation From such a source of learning and respectability we had a 
 right to look for the whole picture. His assertion, for instance, that a 
 good stopping cannot be made without steam heat, porcelain slabs, 
 etc., is a dogmatic assumption which he refutes when he further says 
 Hill's stopping lasted thirty years, etc. Hill never used steam heat. 
 
 From my experience with the preparation of the material I am con- 
 fident steam heat is better than dry heat and kneading-sticks. But to 
 say that good results cannot be obtained in the old way is not true. I 
 experimented all one winter to make an improvement in the texture of 
 the manufactured material, as there was such an evident falling oft' in 
 quality, and I found the whole trouble was with the base. Until the 
 material can be obtained as it used to be, by cutting the tree, I propose 
 to use the filling for what it is worth, as I find it, not expecting too 
 much from it, or what was once realized. 
 
 The President. The next contribution to the subject of the evening 
 will be a paper by Dr. Bogue, which he will kindly read now. 
 
 Dr. E. A Bogue then read the following paper, entitled : 
 
 "FILLING MATERIALS AND METHODS," 
 
 in which, after referring to materials and methods, he continued as 
 follows : 
 
 ' I think we all owe our thanks to Dr. Flagg for his late discourse 
 oy gutta-percha, and especially for the clear way in which he has 
 defined the class of cases where its use as a filling for decayed teeth is 
 indicated. His enthusiasm leads him to say some things, however, that 
 ought to be challenged. If he is right, it can be proven ; if wrong, it 
 is the function of this society to point it out. 
 
 'As one person, I regret that Dr. Flagg felt it necessary to excuse 
 himself for the exclusive use of plastics, or that he cited the fact of his 
 presence before this society as an ' evidence that he had maintained his 
 respectability.' He ought not to need any such evidence. It has been 
 the maxim of this society to 'prove all things, and hold fast that which 
 is good.' So all men having ideas to present have been welcomed. 
 
 " It has been Dr. Flagg's effort for more than twenty years, of my 
 personal knowledge, to save teeth that many other practitioners would 
 extract The good that he has accomplished commands sincere respect ; 
 but I cannot say as much for some of his statements and some of his 
 methods. I regret to hear such words as these : 'I want to induce you 
 to try these things, for certainly you must understand that you know 
 little or nothing about plastic fillings. You may have been told that 
 my practice is among the rag-tag and bob-tail from the gutters of Phila- 
 delphia, but you know very well that my patients are among the very
 
 best, the most intelligent, and the most wealthy of the people of that 
 city, and are typical individuals of their class ; and yet they are perfectly 
 satisfied with the work I do for them.' 
 
 "Comforting the declining years of aged people, even if they are 
 millionaires or members of the best society, by preserving their 
 natural teeth, using the gentlest possible means, whether those means 
 be gutta-percha or amalgam, is praiseworthy. But can we denominate 
 as praiseworthy and strictly scientific a sentence like this: ' If / do 
 not know when it is best to extract a tooth, I do not know which of 
 you does.' Or a question so misleading as this : ' If you place your 
 gutta-percha, properly prepared, where little or no wear can come upon 
 it, in such wise that you know just as well as you know anything that 
 a zinc-phosphate filling would not have lasted two little years, a gold 
 filling would not have lasted five years, an amalgam filling would not 
 have lasted more than ten years, and your gutta-percha filling lasted 
 fifteen years, then I ask of you if gutta-percha properly used is not 
 the most permanent filling material we possess?' Dr. Flagg leads up 
 to an answer which he seems to desire, but it should be recognized that 
 his premises are not generally to be admitted without question, hence 
 his inferences are often fallacious. Very few men, except Dr. Flagg, 
 have seen many gutta-percha fillings fifteen years old, and Dr. Flagg 
 himself is greatly elated by coining across such fillings. In such cases, 
 undoubtedly it was the best material. 
 
 " But when Dr. Flagg's next sentence asserts interrogatively thac 
 gutta-percha, properly used, is the most permanent filling we possess, 
 I think his enthusiasm would make his hearers infer more than 
 he actually means; particularly when he continues by saying, 'I want 
 to leave with you to-night the impression that you can work gutta- 
 percha precisely the same as you work cohesive gold.' Yet farther on 
 he admits the value of copper amalgam in desperate cases. Dr. Flagg 
 counsels us to ' have our gutta-percha tested, so that we know exactly 
 what it is composed of and the proportions of it," and he says ''any 
 man can test it in ten minutes in his office.' Three minutes later Dr. 
 Flagg says : ' We have known positively for half a century that Hill's 
 gutta-percha stopping was not made of quicklime and silex, but do not 
 know what it was made of. So difficult is its ana' lysis that we have 
 not been able to say positively what Dr. Hill made his stopping of A 
 little later in his address Dr. F. says : ' The only way for you to use 
 gutta-percha successfully is to test the various materials before putting 
 them into the mouth. It is the work of a life-time.' 
 
 '"Ten minutes' have lengthened into 'half a century,' and half a
 
 century into a life-time very quickly but, as Dr. Flagg says he tells 
 'the truth, the whole truth, and nothing but the truth,' we must seek 
 to reconcile these conflicting statements as best we may. 
 
 " Dr. Flagg says next : ' I do not want my material to be looked 
 upon as a crutch.' He will, it is hoped, pardon the suggestion that 
 this society was not aware that gutta-percha was a proprietary article, 
 and it must regard all subjects brought before it as absolutely free for 
 discussion. .Dr. Payne asked how Dr. Flagg accounted for the protec- 
 tion of the tooth against decay when the shrinkage of a gutta-percha 
 filling necessarily admits more or less moisture to the cavity, when dis- 
 integration of tooth would ensue if a gold filling leaked? (Please 
 notice Dr. Payne's admission of the correctness of the general belief 
 that a leaky gold filling will allow disintegration of tooth-substance 
 around it.) Dr." Flagg replied that the gutta-percha was a non-con- 
 ductor of galvanic or electric currents, and that, therefore, no chemical 
 action takes place between the gutta-percha and the tooth-bone. He 
 savs the only action that can take place is the leakage of moisture. 
 
 "Dr. Flagg, speaking of amalgams, says that ' amalgam permits 
 moisture to do good.' He claims to recognize that fact, and, therefore, 
 says tiiat ' amalgams that do not shrink are not as good tooth-savers as 
 amalgams which shrink.' He has much to say about tooth-savers, 
 meaning fillings His practice necessarily leads to inaccuracies both in 
 excavation and in adaptation of filling materials. He has invited the 
 worst. class of cases and the worst class of teeth. As it would be a 
 physical impossibility to use gold in most of those cases, Dr. Flagg has 
 elected to use plastics in all of them. The results obtained are the 
 sum of his experience. This experience, though strictly empirical, is 
 most valuable, but it does not justify any one in dogmatic assertions 
 that he cannot prove. All this galvano-electric current assertion comes 
 under that head. 
 
 "If Dr. Flagg could be induced to answer concisely, according to his 
 knowledge, he would agree that the causes of decay in teeth, leaving 
 out of view heredity, which would have to do with form and position, 
 may be summed up in very few words, viz. : that which causes solu- 
 tion. Now, solution of the enamel never takes place at any point 
 where it is exposed to friction, but only in such spots or crevices as 
 favor the retention of foreign substances which, under the combined 
 influences of heat, moisture and atmospheric contact, speedily produce 
 disintegrating acids in a nascent condition. The experienced dentist 
 knows full well where to look for dental decay. The smaller the 
 crevice the longer it takes for the enamel to break down, but Dr. 
 McQuillen showed many years ago how, between two plates of sound
 
 enamel, the substances that produce decay may reach the dentine, and 
 so largely disintegrate it as to cause almost total destruction of the 
 crown before the patient is conscious of disease. How, then, can we 
 be told that leakage is a benefit? How can those amalgams that con- 
 tract be vaunted as the best ? How can gutta-percha be regarded as 
 anything else than a valuable adjunct to our various filling materials? 
 
 "We must necessarily challenge the statement that 'amalgams that 
 do not shrink are not as good tooth-savers as amalgams whichs hrink,' 
 for both palladium and copper are recognized as being the best pre- 
 ventives of decay among all the amalgams, yet these two do not shrink. 
 Dr. Flagg himself counsels copper amalgam in desperate cases. 
 
 " Dr. Flagg goes on to say : ' In five minutes you can tell whether an 
 amalgam will shrink or not.' This is absolutely incorrect in regard to 
 any strange or new amalgam. I have tested several amalgams that 
 have continued to change their form for several days, sometimes shrink- 
 ing, sometimes expanding. 
 
 "I think Dr. Flagg scarcely meant that he could ascertain in thirty 
 minutes the composition 'of a new amalgam; still less its quantitative 
 composition. Yet one might infer that from his saying that he could 
 ascertain its composition in thirty minutes. 
 
 " In advocating gutta-percha for front teeth, Dr. Flagg failed to stace 
 that this material often becomes so dark on the surface as to be more 
 unsightly than many amalgams, and always changes color, becoming 
 fluffy or soiled. 
 
 " Having thus called attention to a few of the inconsistencies and 
 errors in Dr. Flagg's address, I beg to call attention to another portion 
 of that same address which contains the most precise, accurate and 
 concise description of where and when to use gutta-percha that I have 
 ever heard : 'Gutta-percha is not presented as a material suitable for 
 all sorts of cavities, but only those having circumscribed walls com- 
 paratively round, shot-hole cavities in the buccal, distal and mesial 
 surfaces of teeth, not on the articulating surfaces ; where the cavity is 
 small on the outside and large on the inside, and where the tooth is 
 soft, of frail structure and highly organic ; such cavities as would be 
 prepared for gold filling by cutting away all the surrounding enamel 
 walls until you get to strong walls in filling such cavities with gutta- 
 percha you conserve the enamel structure all that you possibly can.' If 
 you add frail and loose teeth and badly leaning ones to this category, it 
 epitomizes the best features of the paper." 
 
 Dr. Perry. One good result of Dr. Flagg's lecture is the most
 
 excellent paper that we have just listened to from Dr. Bogue. I am 
 in accord with almost every sentiment that he has uttered on that sub- 
 ject. 
 
 REPLY. 
 
 " IX ABSKXTIA." 
 
 BY J. FOSTER FLAGG D. D. S., PHILADELPHIA, PA. 
 
 Honors conferred in this fashion are sometimes creditable and some- 
 times discreditable alike to donors and recipients. If creditable, then 
 all is well, but if discreditable, either to donors or recipients, then all 
 is not well. 
 
 At the meeting of the New York Odontological Society, held Feb- 
 ruary i4th, iSSS, I had the pleasure of speaking in behalf of gutta- 
 percha stopping, and, after two months had passed, at a meeting of the 
 same Society, held April loth, 1888, reported in July Cosmos, p. 475, 
 Drs. E. T. Payne, and E. A. Bogue gave utterance to comments upon 
 my effort which are so discreditable to themselves, and which, if true, 
 would be so discreditable to me that I deem it my duty to reply at once. 
 
 First, for Dr. Payne ; I do not admit that my effort would have been 
 more profitable as a paper than it was as an address, and I judge of 
 this matter from the expressions of opinion as to its value which were 
 given me by voice upon that occasion and which have been repeated 
 by scores of letters received since. 
 
 As for members asking questions, I think the report in the Cosmos 
 for May indicates that the questioning was pretty lively. 
 
 I wish to antagonize more emphatically than ever, if possible, the 
 " crutch" idea as applied to gutta-percha and to insist upon just that 
 degree of longevity for fillings of this material that I have always 
 assumed, viz. from twice to thrice the durability of gold when used 
 instead of gold in places which are frequently filled with gold and 
 which should be filled with gutta-percha. 
 
 I deny the assertion that fillings made of the gutta-percha stoppings
 
 8 
 
 of the present day are inferior to those of former times ; and the state- 
 ment made by the gentleman that such fillings will not last longer than 
 from two to eight years, merely because he does not happen to know 
 any better, is ''suggestive and amusing, to say the least." 
 
 I have hundreds of such fillings made from such gutta-percha which 
 are now more than ten years old and which, with the exception of very 
 trifling wear, are as good as when introduced and which are saving the 
 soft, frail teeth perfectly. 
 
 In my experience the average of well introduced good gutta-percha 
 work of the last decade is equel to, if not superior to, that of thirtv 
 years ago; therefore, the inference that such results are obtained is 
 neither " misleading" nor " untrue" 
 
 It is true that I did say that it was a duty that operators should 
 "test" their gutta-percha stopping, that from such ''testing" might be 
 known the approximate degree of heat at which it softens (as I ex- 
 pressed it, *' its heat-grade") and also exactly its composition, (as I ex- 
 pressed it, "just the proportions of organic and inorganic matter ") 
 and it is equally true that I said that an analysis was a very difficult 
 piece of work, and the attempt to make a point on these two assertions 
 merely because the gentleman did not happen to know the difference 
 in gutta-percha work between "testing" and ''analysing" is "sugges- 
 tive and amusing, to say the least." 
 
 Regarding my assertion that the formula for "'Hill's stopping," is 
 unknown, I would say that I have, during the past twenty-five years, 
 embraced every opportunity to ask those of our profession from whom 
 I deemed it possible I might obtain information as to the formula of 
 this (at first) excellent material, and, in every instance I was told by 
 each individual that he "did not know." 
 
 It was from this fact that I said that our information was " meagre /" 
 
 And now I would ask further if Dr. Payne was a student with Dr. 
 Hill, and if he made some ot that material, and if he knew of what 
 it was composed and what were the proportions, why has he not 
 published all this long ago ? 
 
 He tells us that if we used any of Hill's stopping of twenty-five years 
 ago we used that which he made ; but if my recollection serves me, it 
 was just about that time that the quality of Hill's stopping com- 
 menced markedly to deteriorate. This might have been merely coin- 
 cidental, but the reminiscence is " suggestive and amusing, to say the 
 least." , 
 
 That he thinks he knows I do not doubt, but that he knows I regard 
 as an open question, and if it could be proven by analysis that he
 
 9 
 
 thought he knew, but did not, it would also be "amusing, to say the 
 least." 
 
 Students oftentimes think they know. 
 
 I do not see by what authority the gentleman states that / know, "of 
 course, that the best stopping in the market to-day is very much inferior 
 to the article which gave the rilling material its deservedly high repu- 
 tation," for I do not know any such thing. 
 
 The gentleman speaks of Hill's and Bevans' stoppings, but my 
 record of gutta-percha work was not made with either of these I could 
 not speak for gutta-percha with views based upon that material as 
 given us "twenty-five or thirty years ago." 
 
 I refer to the gutta-percha of the last twenty-live years, with its 
 gradual improvement in lessened quantity of inorganics with mainte- 
 nance and increase of heat-grade ; with its improved toughness and 
 with its improved working qualities. 
 
 If the gentleman is not aware that as crude gutta-percha has deteri- 
 orated, gutta-percha stopping has nobly held its own, he should post 
 himself before speaking, because "from such a source of learning and 
 respectability we have a right to look for the whole picture." 
 
 And so, because Hill never used steam heat, the statement that it is 
 essential to use it now, is a " dogmatic assumption ! " 
 
 Hill had the crude gutta-percha of the cut-down trees. We, of 
 to-day, have only the crude gutta-percha of the tapped trees therefore, 
 Hill could dispense with that care and nicety of manipulation which 
 we of to-day find essential to the production of an acceptable result. 
 
 It seems to me that to assume that my assertion was a dogmatic 
 assumption is itself a dogmatic assumption ! 
 
 The gentleman states that he "experimented all one winter" to 
 improve the texture of the manufactured material, but he found the 
 whole trouble was with the base. 
 
 I have been systematically experimenting for the same purpose for 
 more than twenty years, and I feel that I have been rewarded for my 
 labor, which, however, would only seem to indicate that I can do more 
 in twenty years than the gentleman can in "one winter" which I 
 guess is true ! 
 
 Second, for Dr. Bogue ; after having, in a paper on "Filling Mate- 
 rials and Methods," asked questions, given answers and drawn deduc- 
 tions just such as would have been accepted twenty years ago, but 
 which I think would be seriously questioned in discussions of the pre-
 
 10 
 
 sent day. the gentleman kindly covers me over with dental sweetness 
 and then swallows me ! 
 
 Truly Bogue-ish and as such a position is not agreeable to me I 
 shall strive to bring about a repetition of the history of Jonah and the 
 whale. 
 
 The jaws open with this, as if quoting from me : " I regret to hear 
 such woids as these, ' I want to induce you to try these things, for cer- 
 tainly you must understand that you know little or nothing about 
 plastic fillings.' " 
 
 I never said so ! 
 
 What I said was this, as reported: "I want to induce you to try 
 these things, for certainly you must understand that from such stand- 
 points as I offer here to-night you KNOW little about plastic fillings," 
 which sentiment, I think, would not be cavilled at by, at least, a ma- 
 jority of those present, and I firmly believe would be most decried only 
 bv those least informed. 
 
 The jaws again open wider with this : ' : Can we denominate as 
 praiseworthy and strictly scientific a sentence like this, 'If /do not 
 know when it is best to extract a tooth, I do not know which of you 
 does,' " as if quoted from me ! ! 
 
 I never said so ! 
 
 In speaking of banding together loose and shaky teeth, I said : " It 
 has been said that teeth in this condition had better be extracted. Is it 
 best? And if / do not know when it is besc to extract a tooth, I ask 
 you who of you does?" 
 
 Simply a question, and no assertion. I do not see that seeking 
 information is ^^-praiseworthy, or that the position or question was 
 absolutely ?/-scientific. 
 
 Again, the gentleman insinuates that I advocate the use of gutta- 
 percha "precisely as I would use cohesive gold!" and he kindly calls 
 that "enthusiasm" when the context of the report will show that in 
 truth I was speaking against that kind of use of gutta-percha which 
 would be likery to result from the idea that it was a temporary filling ; 
 then it was that I said that I wanted "to leave with you to-night the 
 impression that you can work gutta-percha precisely the same as you 
 work cohesive gold," meaning carefully, with accuracy, and with the 
 idea that with such work it would be compensatingly permanent ; and 
 this, / have reason to believe, was generally and thoroughly so 
 understood. 
 
 The gentleman next, by a series of gyrations and one utter misquota- 
 tion, lengthens "ten minutes" into " half a century" (not the slightest 
 connection between the statements except the placing of them together
 
 11 
 
 by the gentleman !) and the half century into a life-time, thus giving 
 " not the truth, nor any part of the truth, but everything but the truth " 
 in contradistinction to my usual method. 
 
 In <k testing" gutta-percha the aim is to find out two things the 
 relativity between the organic and inorganic components, and the 
 " heat grade " of the material tested with these two factors one versed 
 in gutta-percha can tell much as to the quality of his material for 
 those who do not know the difference between "testing" and "ana- 
 lyzing" it does not tell much ! 
 
 " Testing" can be done in " ten minutes" 
 
 The gentleman then mixes the next two quotations and draws his 
 deduction with a child-like innocence which, for New York, is 
 refreshing ! 
 
 He says that / say : * The only way for you to use gutta-percha suc- 
 cessfully is to test the various materials before putting them into the 
 mouth. It is the work of a life-time "!!!!!!! 
 
 The admiration marks are mine, but I could not help putting them 
 there, for again, 
 
 I never said it ! 
 
 After, as he quotes, urging the "testing" of the various materials 
 (gutta-percha stoppings) before putting them in the mouth, I said : 
 "The testing of the value of the various inorganics is the work of a 
 life-time." 
 
 The whole range of amalgam remarks in which the gentleman 
 indulged are so indicative of utter superficiality that I shall simply pass 
 them over as beneath my notice, merely intimating that his testing of 
 "amalgams that have continued to change their form for several days, 
 sometimes shrinking, sometimes expanding," is probably about as valu- 
 able and reliable as was his " little bottle and warm water bath " experi- 
 ment to determine whether or no amalgam fillings would produce 
 mercurial ptyalism ! 
 
 But when the gentleman not only misquotes me, but italicizes the 
 word I NEVER USED to give point to his assertion, I think it time 
 that I should strongly denounce such unworthy and despicably unsci- 
 entific conduct. 
 
 He says that / said : "I do not want my material to be looked upon 
 as a crutch," and comments upon this as follows ; " He will, it is 
 hoped, pardon the suggestion " (how velvety soft is the odious phrase- 
 ology !) " that this society was not aware that gutta-percha was a pro- 
 prietary article, and it must regard all subjects brought before it as 
 absolutely free for discussion." 
 
 I NEVER SAID SO !
 
 12 
 
 After referring to Dr. Atkinson's former endorsement of gutta- 
 percha as a " crutch," what I did say is this " I do not want it to be 
 welcomed on any such terms as that. I do not want this material to 
 be looked upon as a crutch. I wish it to be looked upon as a reliable 
 friend in need !" 
 
 Thus it will be seen that as no u proprietary " word or thought was 
 indulged in by me, all his Mephistophilish sarcasm falls harmlessly to 
 pieces from its own rottenness, as it has not the slightest foundation 
 in truth to rest upon ! 
 
 Extract from Odontological Society Report, p. 487, July Cosmos. 
 
 The President. Gentlemen, we have Dr. Niles, of Boston, with us to-night, and we 
 would be glad to hear from him. 
 
 Dr. E. S. Niles. This is too great a subject for one to speak upon impromptu. We 
 have considered the subjeft of amalgam in the American Academy of Dental Science 
 for the last two meetings, and I must say that the result of the discussion is rather 
 unsatisfactory. In fact, the present information on the subject discourages me in the 
 use of amalgam. I now speak exclusively of copper amalgam. Since I have been in 
 practice, I have been more or less dissatisfied with these fillings, as I think we all 
 have, and have looked forward to some day when I might take up tha subject for the 
 purpose of making some satisfactory experiments. I regard the present investigation 
 of amalgams as superficial, for the reason that w.hen we speak of amalgams we may 
 refer to any number of compounds, all of which may vary in their composition. 
 
 Etc., etc. for a page or more of remarks all of which seem to indi- 
 cate that when the gentleman has "experimented" he, perhaps (?), 
 will know more of the " great " subject upon which he is trying to speak. 
 
 He next continues as follows: "I was going to say in regard to the distinguished 
 professor who addressed this society at its last meeting, that I am sorry he does not 
 tell us fully and conclusively of what his compounds are composed, and in a way that 
 would enable us to make similar preparations for ourselves. I am sorry to say that 
 such is not the case, as my own experiments, as well as the experiments of my 
 brethren in Boston and other cities have proved. Some years ago, while attending 
 school in Philadelphia, I boarded not far from Dr. Flagg's, and we used to have on the 
 table what the mistress was pleased to call 'scrapple.' I was very much interested 
 to know of what it was composed, and was told it was made of bits that came from 
 the table, into which she put eggs, pepper and various things.- It might, therefore, be 
 made of one thing-one day, but of entirely different things the next. In reflecting 
 upon this subject I have wondered whether the making of mysterious compounds in 
 Philadelphia was confined to the manufacture of 'scrapple' alone, or whether other 
 combinations in that city may not have a similar origin. 
 
 "As long as the profession consent to use alloys the composition of which they are 
 not familiar with, no complaint can be entered against those who make amalgams or 
 'scrapple ' alloys.' 1 
 
 What a powerful reflector ! 
 
 From his not knowing " fully and conclusively " of what my com- 
 pounds are composed it is evident that he has not read " Plastics and 
 Plastic Filling," in which work he would find just what " bits that
 
 13 
 
 come from the table " are best adapted for each particular kind of 
 " scrapple." 
 
 When it is remembered that "scrapple" is a compound of Indian 
 meal and pork scraps (hence its name) it would seem that some Phila- 
 delphia wag was playing upon the credulity of the scholar from Bos- 
 ton, whose thirst for knowledge would evidently have been satisfied 
 with the information that u -fish balls" were composed of chicken and 
 turnips. 
 
 And when it is also remembered that the scholar from Boston is 
 the gentleman who conferred upon dentistry the inestimable boon of 
 the "hermetically sealed tubes" for the maintenance of the integrity 
 of phosphoric acid menstruum just two years after it had been experi- 
 mentally proven and taught that such menstruum "changed" practi- 
 cally at the same time, whether kept in hermetically sealed bottles, ordi- 
 narily stopped bottles, or in 'wide mouthed -vessels open to the air'. 
 
 And when he is further recognized as the author of the exciting 
 Newark anecdote of the young lady who asked him u if he was from 
 Boston?" to which he replied that he " was from Boston," to which 
 she replied that she, '-also, was from Boston" so they were both 
 from Boston! it goes without question that to repel an attack from 
 such a source would be merely to inaugurate another k ' Mosquito War ! " 
 
 I visited New York in the acceptance of cordial and repeated invita- 
 tion ; I took with me for presentation, the carefully prepared results of 
 many years of conscientious endeavor to add to the resources of our 
 profession in its work of doing good. 
 
 I was unconscious of having either thought, said or done anything 
 which was other than interesting, instructive and acceptable. 
 
 I was not only congratulated and thanked upon that occasion, but I 
 have since received, from there, several written acknowledgments of 
 interest and satisfaction. 
 
 I am accustomed to personal abuse, and I have always striven to 
 live above it, but I must openly and decidedly protest against such 
 comments and papers as those of Drs. Payne and Bogue, which with 
 impertinent assurance accredit me with views which I do not hold ; 
 with knowledge which I do not acknowledge, and with fallacious 
 deductions from what might be admitted if I "could be induced to 
 answer concisely !" 
 
 And I must also say that I was not prepared to find, as I did from 
 the April proceedings, that I was not only left alone to fight for myself

 (which, I am thankful I feel completely able to do,) but such vile 
 effort was characterized as " excellent ! " 
 
 Candid, fair and honorable criticism of my views I have always 
 earnestly invited, and when by time or argument I have been proven 
 in the wrong I have always cheerfully and thankfully acknowledged it. 
 
 But when malicious sneers, deliberately concocted mis-statements and 
 italicized perversion of the truth are returned for kindly effort, I think 
 the right will be conceded me to feel that, in certain degree, I have 
 been foolishly "casting pearls before swine."
