This chapter describes laboratory protocols for TEM and SEM approaches allowing the examination of the dental hard tissues' constituents at the ultrastructural level. TEM has the highest resolution power to examine the cellular and extracellular matrix ultrastructure inside a given sample, detecting the presence, location, and quantification of organelles related to the metabolism of the cell type as well as membrane specializations. SEM allows the observation of the sample surface, for examining dimensional topography and distribution of exposed features.
本章介绍了透射电子显微镜(TEM)和扫描电子显微镜(SEM)方法的实验室方案,这些方案可在超微结构水平上检查牙齿硬组织的成分。TEM具有最高的分辨率,可用于检查给定样本内的细胞和细胞外基质超微结构,检测与细胞类型代谢相关的细胞器的存在、位置和定量,以及膜特化情况。SEM则可用于观察样本表面,以检查暴露特征的尺寸形貌和分布。
