Fistulograph

A fistulograph is a radiographic investigation to localise the origin of a sinus tract. A small size gutta-percha point (nr. 25 - 30) is inserted into the sinus tract using forceps/tweezers. The point is advanced in small increments in the direction of least resistance. Local anaesthesia is rarely needed. Usually approximately 10 - 20 mm of the point can be pushed into the tract. A fistulograph can provide valuable information about the site of an acute infection. In the two radiographs above, the infection originated from the root filled tooth 13 while tooth 12 was vital.
