The Aetiology of Non-Carious Cervical Lesions - A Mini Review

ABSTRACT

Non carious cervical lesions are characterized by the loss of tooth structure at the cementoenamel junction caused by wear processes and not by bacterial activity. They have clearly defined edges that are deeper rather than wider, and their internal angle can be either more rounded or sharp. They appear in a variety of shapes and sizes, and are categorized as wedge­shaped, grooved, concave, irregular and shallow NCCLs. Studies show that their aetiology is multifactorial, amongst which are erosive agents, acidic diets, oral hygiene habits (technique, frequency, force, duration), occlusal stress forces and some medical conditions(GERD).
