Etiological factors associated with non-carious cervical lesions: a current overview

Abstract

This is a literature review about the main etiological factors of non-carious cervical lesions (LCNCs), considering their multifactorial aspects and their increasing prevalence in the population. National and international journals were consulted in the databases (Virtual Health Library, Pubmed and Google Academic), as well as theses and books related to the theme. Articles published from 2010 to 2019 were selected according to the inclusion / exclusion criteria. LCNCs are characterized by dental mineral loss in the cervical region, without bacterial involvement, varying in shape, symmetry and location. These lesions have been growing around 5 to 85%, which highlights the importance of the present study. Biocorrosion, abrasion and abfraction are considered the main etiological factors, and a common patients complaint is dentin hypersensitivity. Curiously, risk groups have been related to LCNCs such as sports athletes, post-orthodontic individuals, and gastroesophageal disease patients. Thus, it is concluded that the knowledge of the etiological factors is essential to guide an adequate diagnosis and then to the correct therapeutic management.
