Comparison of microleakage of two materials used as fissure sealants with different methods: an in vitro study.

Background: Marginal seal has a principal role in durability and clinical success of fissure sealants. The aim of this study was to compare the microleakage of two materials used as pit and fissure sealant with different methods of application.

Methods: The 55 extracted premolars were assigned randomly to one of the following five groups: Group 1: Acid-etching (ultra-etch) + fissure sealant (conventional method), Group 2: Acid etching + bonding agent (single bond) + fissure sealant, Group 3: Self-etching primer + bonding agent (SE bond) + fissure sealant, Group 4: Acid-etching + bonding agent + flowable composite (Filtek flow), Grope 5: Self-etching primer + bonding agent + flowable composite.
