The Development and Evaluation of Cervical Dentine

Abstract

Olivia Smith

The enamel layer is thinnest at the cervical region of the teeth, which is a structural weak point. The combined actions of erosion, abrasion, and abfraction stress flexure might destroy the thin enamel layer or cause enamel disintegration in the tooth cervix, exposing dentine or pulp. Noncarious cervical lesions characterised by tooth structure loss at the cemento-enamel junction have no relationship to dental caries. The appearance of NCCLs varies; some have shallow depressions, while others have broad, disc-shaped or huge, wedge-shaped abnormalities. Meanwhile, the cervix of the tooth is the most commonly impacted region by dentine hypersensitivity, an unpleasant sensation caused by exposed cervical dentine in reaction to temperature, evaporative, and tactile stimuli, among others [1].
