[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.
