[Teeth electroexcitability in periodontitis].

Electroodontometric study of 756 intact teeth in 209 patients 18-65 years of age with normal periodontium and different stages of periodontal disease (periodontitis) showed that 96.8% of teeth in patients with mild periodontitis retained normal sensitivity, 68.4% -- with moderate periodontitis and 55% -- with severe periodontitis. Decreased pain threshold was detected in 3.2% of teeth of patients with mild periodontitis, 22.6% -- with moderate periodontitis and 12% -- with severe periodontitis. Increased pain threshold was not detected in teeth of patients with mild periodontitis, but in 9% with moderate periodontitis and in 29% with severe periodontitis it was obvious.

[Postobturation pain associated with endodontic treatment].

Postobturation pain of different origin after endodontic treatment was studied in 100 patients after treatment of 151 teeth with filling of 264 channels. 34.4% patients complained of pain. The incidence and intensity of pain were scored. Postobturation pain clearly depended on the number of treatment sessions, number of channels filled in one tooth, and excessive filling "beyond the apex". The method of "crown down" preparation using completely rotating profile instruments and GT rotary files proved to be most effective as regards prevention of postoperative pain.
