COMPOSITION OF MATTER FOR USE IN DENTISTRY.
No Drawing.
This invention relates to a composition of matter which has an important use and application in dentistry, particularly in connection with the forming of cavities in natural teeth for inlays, etc.
Where cavities are prepared in natural teeth, without devitalizing, the operation of grinding with the usual abrasive stone is in many cases objectionably painful because of the heat generated by the friction of the rotating stone against the cavity wall. The dentist usually dips the stone frequently into Water, not only to facilitate the grinding, but to keep down the heat; notwithstanding this practice the operation is painful, as stated. And still the discomfort thus resulting is not of sutlicient account to justify the trouble incident to producing an anmsthesia by the methods now in use.
According to my invention I propose to utilize, in connection with the grinding implement proper, an anaesthetic-abrasive composition that will be applied to the surface of the grinding instrument, which latter need therefore not be in itself of an abrasive character. Thus, instead of using a carborundum grinding point I may use a metal piece, preferably with such surface characteristics that when it is dipped into the aneesthetic-abrasive compound, suflicient of the latter will be held or fed to the surface to accomplish a certain amount of grinding or abrasion. And as the grinding goes on it will be evident that any anaesthetic quali ties which the composition may have will be applied directly to the tooth structure at the time and place where and when most needed and capable of doing the most good.
The anaesthetic-abrasive composition may be made up of finely divided carborundum, for instance, and a suitable quantity of novocaine in solution, or other anaesthetic familiar to dentistry, the same being brought together into a uniform, homogeneous, stable mixture, with or without some liquid or pastry binder or vehicle, such as for instance, glycerine.
I do not intend any limitations as to the materials or make-up of the anaestheticabrasive composition, further than that it Application filed September 3, 1920. Serial No. 408,045.
shall include (1) an anaesthetizing agent in solution or some form such that when brought into contact with an inlay cavity wall, as described, it will be readily absorbed into the tooth structure and perform its intended function; and (2) abrasive material in finely divided form, preferably though not necessarily inert to the anmsthetic material. The composition may of course include other or additional medicaments,intended to affeet or be absorbed into the tooth structure, and a vehicle such as glycerine. For best practical results care should be taken to make the resulting pasty or semi-fluid or colloid mass uniform and homogeneous throughout, and chemically and physically stable.
For the more effective application of the amcsthetic-abrasive composition I have in vented a device to take the place of the familiar carborundum point. For instance, I may provide a tubular piece, with radial apertures. As this is dipped into the anaesthetic-abrasive composition the tubular body is filled up and some of the material also clings to the outer surface. The tubular member rotates within the cavity just as a carborundum point would do, and the operation of centrifugal force maintains a sup ply of the composition on the outer surface, fed from the tubular body, through the radial apertures. By reason of the friction incident to the grinding, and perhaps also in some degree because of the centrifugal force, the anaesthetic principle or medicament of the composition quickly and effectively does its work, with the result that the grinding and finishing of an inlay cavity or the like may be accomplished with the minimum of pain and discomfort.
I claim 2- An anzcsthetioabrasive composition for use in forming dental cavities, comprising finely divided carborundum and an anaesthetizing agent in solution, and a vehicle for these two whereby they are carried in a fluent state and in an enduringly uniform and homogeneous mixture.
In testimony whereof I aiiix my signature.
