Tooth wear is a general term describing the loss of dental hard tissues, from the surface of the teeth caused by factors other than dental caries, trauma and developmental disorders. Attrition, Abrasion and erosion usually cause alterations of the tooth surfaces and manifest as tooth wear. Tooth surface loss may be considered physiological or pathological. Physiological tooth surface loss occurs as a result of mastication and adjustment, which is required for the teeth to function correctly.

... siological tooth surface loss may also occur at interproximal tooth surfaces due to friction between the adjacent teeth. Inversely, pathological tooth surface loss represents unacceptable levels of dental hard tissue loss. It is characterized by abnormal destruction, which may require treatment. The aim was to assess the reason for tooth material loss among FMR diagnosis patients. A retrospective study sample of 65 cases was collected from DIAS(Dental Information Archiving Software). The data was converted into an excel sheet for tabulation and further statistical analysis were done in SPSS. The p-value was insignificant and the current study proves that the reason for tooth material loss is predominantly caused by attrition. Within the limits of the study, the reason for tooth material loss is due to attrition.
