Aspectos clínicos da etiologia da hipersensibilidade dentinária cervical

Abstract

This research was developed with the purpose to study some clinical aspects of cervical dentin hypersensitivity (HSDC). A total of 32 pacients were identified with the HSDC symptom being 97 teeth examined. Based on the anamnesis and clinic examination, the lesions were classified according to the presence of abrasion, erosion or abfraction. The important HSDC related factors were more efficient/frequent hygiene, periodontal treatment, ingestion of acid aliments and oclusion trauma. The most frequent occurances were observed in small lesions in the radicular region. The most affected teeth are bicuspids and the cervical sensitivity is frequently more related to abrasion influence.
