Abstract

Dental attrition is a type of physiological tooth wear at the incisal or occlusal surfaces caused by tooth-to-tooth contact, resulting in loss of tooth tissue. Abrasion is loss of tooth structure due to contact with external foreign object. At the cementoenamel junction, the progression of tooth loss can be rapid since enamel is very thin in this region of the tooth. Erosion is the loss of tooth substance as a result of chemical action on the tooth surface. The smooth lesions exhibit no chalkiness and are common on the palatal and lingual surfaces of the teeth. Treatment of attrition, abrasion and erosion are also described briefly in this chapter.
