Scanning electron microscopic study of human gingival epithelial cells on the surface of teeth and glass slides.

Scanning electron microscopy was used for a comparative study of gingival epithelial-like cells grown on glass slides and epithelial remnants on extracted teeth. The micrographs showed that the shape, surface morphology, edges, intercellular contacts, light areas, and fibrous-like products of the cells were quite similar. The method facilitated identification of epithelial cell remnants in the gingival pocket area of extracted teeth.
