Histopathology of Caries-Like Lesions Created in vitro in Fluorosed and Sound Enamel

Abstract

The acidified-gel artificial caries technique has been used to produce in vitro caries-like lesions in fluorosed and sound enamel. Both abraded and unabraded surfaces were exposed to attack. Results showed that the histological features were similar in fluorosed and non-fluorosed specimens, although the pore volumes in the body of the lesion were much less in fluorosed specimens despite their initial porosity. Where the surface was abraded, greater depth of lesion penetration was noted with no intact surface zone. This may indicate that the surface enamel exerts some protective effect.
