Describe the operation for the repulsion of a diseased upper molar 

 tooth of a horse. 



Shave and disinfect the field of operation. Remove a circular 

 piece of skin and trephine through the bone and alveolar plate, 

 immediately over the fang of the tooth. With scalpel and chisel, 

 separate the bone and soft tissues over the entire area of the diseased 

 tooth. Apply a punch against the fang of the tooth and give a few 

 sharp blows with a mallet, directing the force in a line with the 

 long axis of the tooth, driving it into the mouth. If the tooth cannot 

 be dislodged in this manner, comminute it with the chisel and mallet 

 and remove the fragments. Cleanse and disinfect the wound after 

 each meal, or at least once daily.
