SEM observations of Retzius lines and prism cross-striations in human dental enamel after different acid etching regimes.

Abstract

OBJECTIVE AND DESIGN Sectioned and ground enamel surfaces need to be etched with acid in order for the enamel structure to be exposed for study in the SEM. In the present study Retzius lines and prism cross-striations were observed in variably ground specimens after etching with nitric acid of different concentrations (0.1, 1, 2.5 and 5%) and for different… (More)
