Scanning Electron Microscope Studies of Dental Enamel

Abstract
The capability of the scanning electron microscope (SEM) was evaluated for ultrastructural studies of dental enamel. Sound, acid-etched, and EDTA-treated enamel samples were examined, It was found that acid causes demineralization of prism cores, whereas EDTA attacks their peripheral boundaries. The scanning electron microscope appears to be exceptionally well suited for studying sound and experimentally treated dental structures.
