本研究的目的是获得有关自然发生的根龋的详细组织病理学信息。对50颗有不同程度根面龋的离体牙进行了纵向切片，并进行了透射光、偏振光和显微放射照相检查。牙本质龋的组织学区域的发生被制成表格，并显示在所有情况下的病变体。光学显微镜显示相同的基本功能，显微放射照相术，是最有用的，当部分吸收喹啉。当使用喹啉时，在77%的病例中观察到病变主体下方的无结构区。这种液体更清楚地定义了病变的范围，并可能显示出“酚反应”时，使用偏振光显微镜。在几乎80%的切片中观察到部分不透射线的表面层。这项研究详细描述了根龋的组织病理学，并帮助开发模型系统来评估这一新兴的牙齿健康问题。
The purpose of this study was to obtain information about the detailed histopathology of naturally occurring root caries. Fifty extracted human teeth exhibiting some degree of root caries were sectioned longitudinally and examined with transmitted light, polarized light and microradiography. The occurrence of the histological zones of dentinal caries was tabulated and revealed a lesion body in all cases. Light microscopy showed the same basic features as microradiography and was most useful when the sections were imbibed in quinoline. A structureless area below the main body of the lesion was observed in 77% of the cases when using quinoline. This fluid more clearly defined the extent of the lesion and may show a "phenolic reaction" when using polarized light microscopy. Partial radiopaque surface layers were observed in almost 80% of the sections. This study has described the detailed histopathology of root caries, and aids in the development of model systems to evaluate this emerging dental health problem.
