牙齿 是脊椎动物口中钙化的层状结构。牙齿的主要刚性成分是牙釉质和牙本质。牙釉质是人体内硬的物质，牙本质比骨头硬，但比牙釉质软。对牙齿的力学性质进行研究，了解其在体内的结构功能、病理学对牙齿力学及相关临床问题的影响、新型牙齿修复材料的开发和牙齿生理学的研究。

Teeth are calcified, layered structures in the mouths of vertebrates. The main rigid constituents of the tooth are the enamel and dentin. The enamel is the hardest material in the body and dentin is harder than bone but softer than enamel. The mechanical properties of teeth are studied to learn about: its structural function in the body, the effects of pathologies in tooth mechanics and related clinical issues, development of new tooth reconstruction material and research in tooth physiology.
