SEM investigation of the variability of enamel surfaces after simulated clinical acid etching for pit and fissure sealants.

Abstract

Etching preferentially occurs on cuspal inclines and on premolars vs molars. After longer times, etching occurs near the pits and fissures. Enamel rods etch at cores and prism borders simultaneously in the same area. Longer etching times produce more enamel surface relief, permitting better sealant adaption to the enamel.
