问题陈述。尽管硬组织损失的所有过程都很重要，但咬合表面的磨损引起了我们的注意。研究目的。通过体积损失和平均深度损失独立测量连续两年以上年轻人的牙釉质磨损率。确定因性别和磨牙症临床诊断而导致的牙齿磨损的任何显着差异。材料和方法。严格的牙科印模协议提供了环氧树脂模型，并使用零点接触笔将其数字化。 AnSur 软件提供了磨损面变化的完整形态描述。结果。第一年测量的所有牙齿的平均损失体积为 0.04 毫米(3)，深度为 10.7 微米。结论。累积磨损两年后，这些数字大约翻倍。
Statement of problem. Although all the processes of loss of hard tissue are important, attrition on the occlusal surfaces commands our attention.Purpose of study. The enamel wear rate of is young adults over 2 consecutive years was measured independently by volume loss and mean depth loss. Any significant differences in tooth wear resulting from gender and a clinical diagnosis of bruxism were identified.Material and methods. A strict protocol for dental impressions provided epoxy models, which were digitized with a null point contact stylus. AnSur software provided a complete morphologic description of changes in the wear facets.Results. The mean loss for all teeth measured was 0.04 mm(3) by volume and 10.7 mu m by depth for the first year.Conclusions. These numbers were approximately doubled at 2 years of cumulative wear.
