ultrastructure study of surface enamel caries

ABSTRACT

The surface enamel of twenty - five molars treated with lactate butter at various intervals [4 hours, 8 hours, 24 hours, 7 days and 14 days] were studied by scanning electron microscopy .The results showed dissolution of the microsurface and widening of the intercryslalline spaces. With increasing time of exposure to the lactate buffer the destruction of the surface became of irregular pattern with the observation of irregular crystal arrangement
