Lewis, R. and Dwyer-Joyce, R.S. (2005) Wear of human teeth: a tribological perspective. Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 219 (1). pp. 1-18. ISSN 1350-6501
Abstract
The four main types of wear in teeth are attrition (enamel-on-enamel contact), abrasion (wear due to abrasive particles in food or toothpaste), abfraction (cracking in enamel and subsequent material loss), and erosion (chemical decomposition of the tooth). They occur as a result of a number of mechanisms including thegosis (sliding of teeth into their lateral position), bruxism (tooth grinding), mastication (chewing), toothbrushing, tooth flexure, and chemical effects. In this paper the current understanding of wear of enamel and dentine in teeth is reviewed in terms of these mechanisms and the major influencing factors are examined. In vitro tooth wear simulation and in vivo wear measurement and ranking are also discussed.
