In Chapter XXX the author gives an account of five cases of dental replantation and one of transplantation. This last operation was carried out on a captain who had the upper canines on the left side decayed and aching; he inquired of the author if it were possible to draw it and replace it by another person’s tooth. Having received an affirmative reply, the officer sent immediately for a soldier of his company to whom he had already spoken on the subject. This man’s canine was found by Fauchard to be too large; nevertheless, for want of better he extracted and transplanted it, after having diminished it in length and in thickness. This it was not possible to do without the cavity of the tooth remaining open, and for this reason, when, after about two weeks’ time it had become quite firm, he stopped it. But the stopping immediately caused such insupportable pain (which circumstance astonished the writer not a little) that he was obliged to take it out again the following day, on which the pain ceased directly. Fauchard saw this patient eight years afterward, and was assured by him that the transplanted tooth had lasted him six years, but that its crown had been gradually destroyed by caries. The root had been extracted by a dentist, not without considerable pain.[439] We now give one of his cases of replantation in the words of the author himself: “On April 10, 1725, the eldest daughter of M. Tribuot, organ builder to His Majesty the King, called on me; she was tormented by violent toothache caused by caries of the first small molar on the right side of the upper jaw; but although she was desirous of having the tooth removed, to be freed of the pain, she, on the other hand, could not, without difficulty, make up her mind, thinking of the disfigurement which its loss would occasion, and thus it was that she was induced to ask me if it would not be possible to put it back again after having extracted it, as I had already done in the case of her younger sister. I replied that this might very well be done, provided the tooth came out without being broken, without any splintering of the alveolus, or great laceration of the gum. The patient, upon this, completely made up her mind. I extracted the tooth very carefully so as not to break it, neither were the gum nor the alveolus injured in any way. I therefore was induced to put the decayed tooth back in its alveolus, and having done this, I took care to tie it to the neighboring teeth with a common thread, which I left in position for a few days. The tooth became perfectly firm, and only caused pain for two days after being replanted.... To better preserve it, I stopped the carious cavity.”[440]
