Degree of microleakage of a self-etch sealant.

The purpose of this study was to compare the microleakage of a new self-etch sealant (Enamel Loc), with and without acid etching, to a traditional sealant (UltraSeal XT Plus) with acid etching in occlusal fissures. The self-etch sealant had significantly more microleakage than the traditional sealant or the self-etch sealant with acid-etching of the enamel.
