Introduction: marginal microleakage in class ii restorations made using oblique incremental, resin beads and SonicFill techniques were evaluated.

Methods: A quantitative, experimental, in vitro and cross-section study was performed on a population consisting of 30 extracted third molars, in which there were 60 standardized independent class II cavities (buccal-lingual/palatine width of 4mm, mesiodistal width of 4mm and depth of 5mm). The molars were divided into 3 groups: group 1, the conventional incremental and resin beads technique; group 2, the resin beads and SonicFill technique; group 3, the SonicFill and incremental oblique technique. The samples were stained with 0.1% blue methylene for 48 hours, sectioned to evaluate colorant penetration and the surfaces were examined at the margins of the restorations using a 10x optical microscope.

Results: The statistical results show a significant difference in microleakage levels depending upon the restoration technique used.

Conclusion: Restorations made using SonicFill offer greater marginal seal than those using resin beads and incremental oblique techniques.

Keywords: incremental conventional, microleakage, resin beads, SonicFill, fluid resin.
