A History of Dentistry from the most Ancient Times until the end of the Eighteenth Century

by Vincenzo Guerini

He combats an old prejudice that had recently been reinforced by the authority of Jourdain, that is, that it does harm to extract a tooth when the soft parts around it are inflamed and swollen. He likewise combats the prejudice, also of very ancient date, that teeth ought not to be extracted during pregnancy. Only, he considers it as well to avoid the cauterization of the dental pulp in cases of gestation. In extracting teeth, the forceps ought only to be used after the tooth has been luxated by means of the pelican. Serre highly approves of this instrument, although he recognizes it to be a dangerous one in the hands of those who do not know how to make a proper use of it. This author invented or perfected various extracting instruments, among which a conical screw for extraction of roots hollowed out by caries deserves particular mention, and which, under a somewhat modified form, is still in use.

Jean Jacques Joseph Serre.

One of the most interesting chapters of Serre’s great work is the one in which he treats of affections of Highmore’s cavity.[527] He speaks at length of the anatomy of the maxillary sinus, of its relation to the teeth situated below it, of the various modes in which the diseases of the antrum are produced, of their symptoms and treatment. He passes in review the various operative methods, and finds that in general the Cowper-Drake is the one to be preferred to all the others. He says that to open the sinus the simple extraction of a molar suffices in the greater number of cases, the trepanning of the alveolus not being generally necessary.

J. Arneman, in 1766, published at Göttingen a synopsis of surgical instruments[528] that deserves mention in so far that the dental instruments of that time as well as those of earlier periods are therein taken into account with sufficient exactness.

A. F. Hecker attributed the accidents of difficult dentition to a special alteration of the saliva caused by the irritation deriving from the erupting teeth. In these cases the saliva is supposed by him to acquire a high degree of acridness and to become almost similar to the poison of rabies. Departing from this theory, the author declares it to be necessary to mitigate the irritation produced on the gums and other parts of the mouth by the altered condition of the saliva, as well as to modify the quality of the saliva itself and to promote the elimination of the same from the body by emetics and aperients. According to him, liquid carbonate of potash administered in drops, together with syrup of poppy heads, manna, etc., is a most useful remedy, having specially for its effect to diminish the acridness of the saliva.

Besides this remedy, the author extols the use of blisters behind the ears, as also of tepid baths, which calm pain and spasms, favor the excretions, and procure repose and sleep. He rejects the incision of the gums as altogether useless, and is most opposed to the use of opium, which he states renders children liable to apoplexy.

And here we will mention, rather by way of curiosity than for any real historical interest which they possess, two pamphlets on odontitis, published respectively in 1791 and 1794 by Ploucquet and Kappis, who maintained that not only the dental pulp, but all the parts that form the tooth are susceptible of inflammation.[529] In Kappis’ pamphlet we find the following ideas developed, upon which we do not think necessary to comment. The inflammatory process consists essentially in the increased flow of humors to a given part and in a more or less intense reaction of the vital force. Both of these things may take place in the teeth. These are liable to swell, that is, to undergo an increase of all their dimensions, in proof of which assertion the author relates the case of an individual, who when attacked by a violent toothache had found the spaces between his teeth so narrowed that it was no longer possible to make use of his usual toothpick, even if he had tried to do so regardless of pain. But when the toothache was over, the same toothpick again became serviceable as before. He says that there is no cause for wonder that in odontitis no redness of the teeth is to be perceived, for in other inflammations as well, redness is wanting, and, moreover, it exists in the interior membrane of the tooth. As in other inflammations, so also in odontitis, the usual issue is resolution. Dental fistulæ may derive from internal suppuration. The impurities deposited on the teeth are by him supposed to be owing to an increase of their secretion! According to the author, caries, the breaking down of teeth apparently healthy, as well as their falling out, is generally caused by an inflammation of these organs, that is, by odontitis, an affection that, he says, may be of very varied kind, the principal forms being the rheumatic, arthritic, sympathetic, and gastric.

Ranieri Gerbi.[530] In a book by this author we find recommended a very singular cure for toothache, even of the most violent nature. It is in no way scientific, and is besides not particularly pleasant, notwithstanding that the author, professor at the University of Pisa, was a scientist of merit, enjoying special esteem as a mathematician and cultivator of natural sciences.

Under the name of curculio anti-odontalgicus he describes an insect living habitually inside the flowers of the carduus spinosissimus, that could be used with great advantage against toothache, in the following manner: One crushes fourteen or fifteen larvæ of the insect between the thumb and forefinger, and then rubs the two fingers together until the matter remaining upon them is entirely absorbed. Instead of the larvæ (which, as is known, represent the first stage of insect life) one may also use the fully developed insects. One then applies the two fingers that have crushed the insects or their larvæ upon the decayed and aching tooth. If the pain is of a nature to be cured by this means, it diminishes almost instantaneously, and ceases altogether in a few minutes. It is said that the fingers preserve their healing power for a great length of time, even a whole year, and in proof of these assertions Ranieri Gerbi speaks of no less than six hundred cures performed! Other insects besides the curculio anti-odontalgicus, used in the same manner, are said to possess the same curative properties, among them the curculio jaceæ, carabus chrysocephalus, and the curculio Bacchus, which last, says Gerbi, has long been used for this purpose by the peasants of Tuscany. The author also says that some German doctors and naturalists experimented with success with several insects indigenous to Germany as remedies against toothache. These insects, also mentioned in a work published in Bayreuth in 1796, author unknown, are:[531] the coccinella septempunctata, the coccinella bipunctata, the carabus ferrugineus, the chrysomela sanguinolenta, the chrysomela populi, the cantharis or Spanish fly, and others. Later on, Hirsch also extolled the healing power of another insect, the cynips rosarum. With regard to the mode of application, Gerbi says that instead of crushing and rubbing these insects or their larvæ between the fingers, one can use a piece of wash leather in a similar manner.
