Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) for the examination of dental hard tissues

Abstract

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.
