Abstract: Purpose: To determine microleakage and microtensile bond strength (µTBS) of composite restorations bonded with self-adhesive resin-cements. Methods: Six groups of molars were assigned to cements: RelyX-Unicem, Breeze, Monocem, PanaviaF-2.0, Filtek-LS, and Scotch-Bond-Multipurpose (adhesive). For microleakage, Class II preparations were made. Cements were applied onto all cavity walls. Preparations were restored, specimens themocycled and then immersed in red dye. Dye penetration was assessed according to 5-point scale. For µTBS test, 6 mm composite buildups were made over tooth surfaces. Rectangular rods were cut and subjected to tensile force. Mean µTBS and SDs were calculated. Results: RelyX-Unicem and Breeze showed low microleakage, however, they had lower µTBS values. Filtek-LS showed the least microleakage and the highest µTBS with dentin. Conclusion: RelyX-Unicem, Breeze and Filtek-LS will improve marginal seal when used in subgingival Class II composite restorations.
