Marginal microleakage of a sealant applied to permanent enamel: evaluation of 3 application protocols.

摘要: Purpose The purpose of this in vitro study was to investigate and compare the microleakage-occurring after placement a light-curing sealant-to unground permanent enamel which had been previously conditioned using 3 different application protocols. Methods Sixty-three molars were randomly distributed groups according protocol sealant: (1) conditioning with 38% phosphoric acid (group 1); (2) single-bottle dentin bonding agent 2); or (3) self-etching adhesive 3). Samples were: thermocycled; stained; sectioned; (4) examined for marginal microleakage. Results No dye penetration noted 25%, 59%, 40% cases 1, 2, 3, respectively. Conclusions Placement layer prior sealant allows significantly less microleakage than traditional alone. used here seems be an attractive alternative acid-etch technique young children, since it would simplify procedure. Clinical trials should performed assess performance these products before definitive conclusions can formulated.
