Abfraction may be defined as V-shaped or wedge shaped defect at the cervical region of a tooth with different clinical appearances mostly seen as angular notch like depressions on the facial surface of tooth structure at the junction of tooth and gingiva, this may be due to flexure of the cusp leading to mechanical overloading and may also be accompanied by pathological wear such as regressive alterations of teeth. Recent research on non-carious cervical lesions (NCCL) suggests that abfraction is also due to multifactorial etiology. The different types of cervical lesions in the human population is determined by their biological, chemical and behavioural factors. There are two school of thoughts regarding the etiology of abfraction among the population. The first school of thought argues that tooth brushes with other artificial forces may be the causative factors and the second school considered that some internal physiological forces as the causative factors. The second school of thought even though do not provides complete explanation, yet provides a significant role of this cervical lesions. The present review focuses on the etiology and all available treatment plan strategies of non-carious cervical lesions.
