Risk factors for formation of non-carious lesions in cervical area (based on survey)

Abstract

Until now, it was believed that non-carious cervical lesions (NCPP) of teeth usually appear either due to abrasion under the influence of a toothbrush and toothpaste (tooth powder), or due to acid erosion. Over the past two decades, a very large number of new studies have been conducted in which such lesions have been studied. The most important studies are analyzed and integrated into a practical approach to understanding and correctly identifying such lesions. Abfraction, which is a microstructural loss of tooth substance in stress concentration zones, should no longer designate all NCPPs, since these lesions are, as a rule, polyfactorial in origin. The correct name of a specific NCPP depends on the interaction of a specific combination of three main mechanisms: stress, friction and biocorrosion, which are unique for a given individual case. Modifying factors are also considered, for example, saliva, movements of the tongue, tooth shape, its composition, microstructure, mobility, positional protrusion.
