REPUIvSION OF TEETH 



2. REPULSION OF TEETH 

 Fig. 2 



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

 from which the crowns have been broken away, alveolar 

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

 of the forceps. 



Instruments. Mouth speculum, razor, convex scalpels, 

 trephine, bone gouge, I^uer's sharp bone forceps, (rongeur 

 forceps) light and heavy bone chisels, mallet, tooth punch, 

 curette, compression artery forceps, scissors, needles, 

 thread, absorbent cotton, antiseptic gauze, extracting 

 forceps, splinter forceps, tenacula, metal probe. 



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 possible the inhalation of pus, blood 

 or other injurious matter, perfoirm tracheotomy in ample 

 time to avert danger. Anaesthetize locally or generally as 

 required. 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 against the tooth fang. 



If an external fistula exists, the identity of the affected 

 tooth is best determined by passing a metallic probe through 

 it against the diseased fang, while one hand is passed into 

 the mouth and the location of the probe more fully ascer- 

 tained. Care should be exercised in trephining not to inj ure 

 the adjoining teeth. This is best accomplished by palpating 

 with one hand inside the mouth and the other outside in a 

 manner to locate the fang of the affected tooth. The danger 

 is further decreased by using a trephine, the diameter of 

 which is considerably less than the antero- posterior diameter 

 of the tooth.
