摘要
目的：研究早期龋表层结构。方法：采用细菌人工龋实验技术造成早期人釉质龋样损害，用扫描电镜（ＳＥＭ）观察损害的表层结构变化。结果：釉质龋的表层结构有三种形式：①相对完整的釉质区；②局部孔隙区；③不规则破坏区。在相对完整的表层釉鞘增大，晶体间的间隙增大。这些间隙为脱矿过程中矿物质丢失提供通道，出现龋损过程中，表层下的破坏比表层更为明显的典型病理改变。结论：早期釉质龋相对完整的表层概念值得商榷。
Aim: Studing surface layer of enamel carious lesion. Methods: Scanning electron microscopic (SEM) study of the enamel surface layer of artificially carious lesion produced by streptococcus mutans in vitro. Results: Observations revealed that there were three structures in the surface layer imcluding ①areas of apparently intact enamel; ② local holes; ③ an irregular type of destruction. Conclusions: The concept of intact enamel surface layer needs to be reconsidered.
