BACKGROUND:Surface replication is a nondestructive evaluation technique applied in examining surface wear by recording surface irregularities, especially in conditions when surfaces of interest cannot be further manipulated to fit directly under a microscope to be examined. Enamel is the outermostprotective layer of the human teeth and is constantly stressed by mastication forces which results in enamel wear. OBJECTIVE:To date, a procedure combining the clinical and microscopic examination of enamel surfaces is absent, which hinders the early diagnosis and comprehension of the wear process. METHODS:This study investigated the role of replication sheets in registering microscopic wear on human enamel surfaces by both negative and positive replication techniques. RESULTS:The sheets replicated wear features successfully. Sheets were compatible to use with multiple microscopes, with proper preparation, including high resolution microscopes such as the scanning electron microscope and transmitting electron microscope.

基于复制品的搪瓷磨损微观特征检测

背景：表面复制是一种无损评估技术，用于通过记录表面不规则性来检查表面磨损，特别是在无法进一步操纵感兴趣的表面以直接适合要检查的显微镜的情况下。牙釉质是人类牙齿最外层的保护层，不断受到咀嚼力的压力，导致牙釉质磨损。目的：迄今为止，尚缺乏结合临床和显微镜检查牙釉质表面的方法，这阻碍了对磨损过程的早期诊断和理解。方法：本研究通过阴性和阳性复制技术研究了复制片在记录人体牙釉质表面微观磨损方面的作用。结果：该片材成功复制了磨损特征。
