PurposeThe purpose of this study was to examine differences in microleakage in extracted human teeth when placing sealants using conventional acid etching or a self-etching fissure sealant.MethodsA total of 40 intact molars and premolars were randomly assigned to one of two light-cured sealant groups: self-etching fissure sealant Enamel Loc™ (Premier)(Group 1, n=20) and Concise™ White Sealant using conventional acid etching (3M™ ESPE™) (Group 2, n=20). Before thermocycling (x100, 15-7 degrees C) all teeth surfaces were made impermeable with the exception of the occlusal surface. Samples were immersed in 50% silver nitrate for 24 hours, then immersed in Rx development solution (Kodak GBX) and after abrassioned longitudinally until central fissure pit. Pictures were obtained by light microscope and the presence of microleakage was evaluated by two calibrated evaluators (kappa= 0,95).ResultsSignificant statistical differences (p<0,0001) were observed between groups.ConclusionsSelf-etching fissure sealant Enamel Loc™ showed higher microleakage scores
