[Reaction of the ganglia to stress effects in the maxillodental area].
Neurohistologic and histochemical study has been performed of the trigeminal and upper cervical sympathetic ganglia as well as of the nodose ganglion in 35 dogs whose 4 lower teeth were prepared for full metal crowns. It was established that in the polishing of dental hard tissue the ganglia on the prepared side show changes in some neurons, intraganglionic nerve fibers, synaptic endings, in the content and distribution of RNA, glycogen and hyaluronic acid. The maximal evidence of the reaction was noted 1--3 days after operation. The ganglia under study did not show any marked changes following 21--28 days.
