186 VETERINARY DENTAL SURGERT. 



ing altogether, degenerates into a chronic form with a 

 constant secretion of pus varying in quantity, some- 

 times profuse at others almost gone. The charac- 

 ter of the pus also varies at different times; some- 

 times it is thin, at others thick. At all times it has 

 a tendency to adhere around the external opening. 

 It is always more or less fetid. 



TREATMENT. 



Remove the cause. This usually necessitates 

 the extraction of one or more teeth. If due to 

 the accumulation of food between the teeth, its 

 removal should be effected and the parts washed 

 out with a solution of chloride of lime, or carbolic 

 acid, one part to thirty of soft or distilled water. 

 Corrosive sublimate, two grains to one ounce of soft 

 or distilled water makes an excellent disinfectant. 



A very singular case of fistulous opening, due to 

 alveolar abscess, was presented for operation at the in- 

 firmary during the summer of 1887. The right lower 

 fourth molar was diseased and the abscess had 

 broken on the under surface of the inferior maxilla. 

 By carefully introducing a probe into the fistulous 

 opening, it could be passed completely through the 

 jaw and up along side the tooth into the mouth. 

 The diseased tooth was extracted, and the fistula 

 thoroughly syringed out with a solution of corrosive 

 sublimate, two grains to the ounce of water. Re- 

 covery took place very rapidly.
