Biology of tooth wear: experimental studies

牙齿磨损是一个重要的临床问题，无论是老年人谁保留他们的自然牙齿和一些年轻人。牙齿磨损的主要原因是磨蚀（牙齿与牙齿接触造成）、磨损（来自饮食和环境的磨蚀）和侵蚀（由酸性食物和饮料或酸的反流造成）。目前，我们对这些类型磨损的相对意义和过度磨损发生的确切条件的理解是有限的。此外，我们对许多常用牙科材料的磨损特性的了解是有限的。提出的研究将提供重要的新信息：应用咬合力和酸之间的相互作用在口腔环境作为牙齿磨损率的决定因素；使用漱口水和凝胶预防磨损的潜力；常用牙齿修复材料的磨损特性。

Tooth wear is a significant clinical problem for both older people who have kept their natural teeth and for some younger individuals. The main causes of tooth wear are attrition (resulting from tooth to tooth contact), abrasion (from dietary and environmental abrasives) and erosion (caused by acidic food and drinks or from regurgitation of acid). At present our understanding of the relative significance of these types of wear and the exact conditions under which excessive wear occurs is limited. Furthermore our understanding of the wear characteristics of many commonly used dental materials is limited. The proposed study will provide important new information about: the interaction between applied bite forces and acids in the oral environment as determinants of the rate of tooth wear; the potential for wear prevention using mouth rinses and gels; the wear characteristics of dental materials commonly used to restore teeth.
