REPULSION OF TEETH. 1 1 



2. REPUIvSION OF TEETH. 

 PIRATE III. 



Uses. The removal of molars, pre-molar.s, tooth fangs 

 from which the crowns have been broken away, alveolar 

 odontonies. etc., which can not be removed safely by means 

 of the forceps. 



Instruments. Razor, convex .scalpels, trephine, bone 

 gouge, Luer's sharp bone forceps, light and heavy bone 

 chisels, mallet, tooth punch, curette, compression artery 

 forceps, scLssors, needles, thread, absorbent cotton, antiseptic 

 gauze, extracting forceps, splinter forceps, dressing forceps, 

 tenacula, metal probe, mouth speculum. 



Technic. Secure the animal in the lateral recumbent 

 position with the affected .side up. The operating table 

 affords by far the best means for securing for the conven- 

 ience and safety of operator and patient. If the sinuses are 

 so involved as to make po.ssible the inhalation of ])us, blood 

 or other injurious matter, perform tracheotomy in ample 

 time to avert danger. Anaesthetize. Shave and disinfect 

 the operative area and trephine according to the method 

 described in the following chapter down through the alveolar 

 plate immediately over the fang of the affected tooth. Avoid 

 dulling the trephine by .striking it again.st the tooth fang 

 itself. If a tooth fi.stula exists the identi-ty of the affected 

 tooth is best determined by passing a metallic probe through 

 the fistula again.st the diseased fang while one hand is passed 

 into the mouth and the location of the probe aiscertained. 

 Care should be exercised in trephining to not injure the ad- 

 joining teeth. After removing the disc of bone isolated by 

 the trephine, control all hemorrhage and then enlarge the 

 opening and remove the bony tissues till the tooth iang is 

 bared its entire width. Insert a scalpel between the bone and 

 .soft tissues at the margin of the trephine opening nearest the
