[Scanning electronmicroscopic studies on fissure caries in human teeth]

Fracture surfaces and ground sections of human molars with fissure caries were examined under the SEM. The pictures confirmed that with the SEM the topographical location of the fissure as well as the main stages of carious decay in the enamel and dentine (demineralization, infiltration by cariogenic substances and microorganisms) could easily be seen three-dimensionally. Primarily the question of demineralization of prism core and prism periphery was discussed by means of own findings and findings made by other authors.
