Strobelberger held, as did many of the preceding authors, that the extraction of a tooth ought to be the _last_ remedy, that is, to be had recourse to when all others, including cauterization, which he considers as the _last but one_, have proved ineffectual. There are cases, however, in which the extraction of a tooth is absolutely indicated, and here, by the way, the author acquaints us with the following poetic aphorism, which expressed the unanimous opinion of doctors: Si dens pertusus, vel putridus esse notatur, Corrumpens alios, tunc protinus ejiciatur. That is, if one finds that a tooth is hollow or decayed, and corrupts the others, it must at once be extracted. Strobelberger, like the greater number of his predecessors, is fully persuaded that diseased teeth may be made to fall out by the use of special remedies; indeed, this clearly appears from the title of the work itself, as, without doubt, the reader will already have observed. Such remedies are called by him “odontagoga,” and he describes them at great length in five different chapters (X to XIV) of the second section of his book, dedicated to the surgical care of the teeth. In regard to _violent extraction_ of teeth, Strobelberger shows still greater cautiousness and timidity than Celsus or Abulcasis. He requires that, after the gum has been detached, one should endeavor to extract the tooth with the fingers or by means of a thread; if, however, this does not succeed, one may have recourse to the trifid lever; only at last, that is, when even the lever has failed, does he allow the use of an appropriate dental forceps. [Illustration: Wilhelm Fabry.] ARNAULD GILLES, a Frenchman, in the year 1622, published in Paris a work whose curious title we will here note: _The flower of the remedies against toothache_.[336] We know nothing else about this publication, which, however, to judge from its title, cannot be other than a mere compilation. DUPONT, another Frenchman, in 1633, published an important pamphlet, which I have, unfortunately, not been able to see. I can, therefore, only quote what Sprengel says of it.[337] Dupont recommends, in cases of obstinate toothache, the extraction and immediate replantation of the tooth; which, he says, becomes quite firm again, but will no more cause any pain. In confirmation of this, Denis Pomaret related, a little later, a case in which a healthy tooth having been pulled out by mistake, and immediately put back into the socket and treated with astringent remedies, became perfectly firm again.[338]
