[The morphohistochemical shifts in the trigeminal ganglia of dogs with experimental traumatic periodontitis].
A model of traumatic periodontitis was created in 36 mongrel dogs and effects of periapical inflammation focus on trigeminal ganglia neurone structure were studied 1, 2, 3, 6, 12, and 24 months after experimental exposure of the animals. Histologic study was carried out by routine methods. In the first months after the intervention the morphologic shifts in the neurones represented drastic irritation and destruction. Later focal and diffuse inflammatory infiltrates and glial element growth were detectable in the ganglial stroma; reduced biopolymer levels were observed in the neurones and accumulation of their level in ganglial stroma. These data evidence an unfavorable effect of periapical focus on trigeminal ganglion elements.
