Studying of some features of manifestation of hypersensitivity of teeth
Studied prevalence of hypersensitivity of teeth and reaction to different irritants (cold, hot, salty, sweet, a touch) at different defects of enamel and a dentine. Researches showed that the majority of patients had a primary reaction to two irritants - cold and tactile. Thus at 80.9% of patients reaction on some irritants was observed at once. More often the hypersensitivity came to light on frontal group of teeth, than on chewing group. But thus in 34.1% of cases sensitive were both chewing, and frontal group of teeth. The localized form met more often, than generalized.
