Non-carious cervical lesions

Non-carious cervical lesions are commonly encountered in clinical practice and present in a variety of forms. A knowledge of the aetiology of these lesions is important for preventing further lesions, halting progression of lesions already present, and determining appropriate treatment. The most commonly cited aetiological factors thought to lead to the development of cervical lesions are erosion, abrasion and tooth flexure. Evidence supports a multifactorial aetiology for non-carious cervical lesions. The purpose of this paper is to review the evidence for each of these aetiological factors as it relates to the development of non-carious cervical lesions. Specific features of cervical lesions linked to these factors, including their morphology, location, prevalence and distribution by age and sex will be discussed. Suggestions for future research into the cause and prevention of non-carious cervical lesions will be presented.
