Adaptação marginal e microtração de restaurações indiretas fixadas em dentina tratada com adesivo e resina composta de baixa viscosidade

TL;DRAbstract

This study evaluated the marginal adaptation of composite indirect restorations bonded with dual curing resin cements after different strategies to seal dentin with dentin bonding agent and/or associate with a low viscosity composite resin (LVCR).Additionally, it was evaluated the bond strength between composite resin and presealed dentin, in pulpal and buccal walls of class I, prepared for indirect restorations.lntact human molars were ground to obtain a flat surface in dentin and prepared to be restored with Class I indirect composite restorations.Three techniques to seal dentin were tested: 1) Conventional Technique: the bonding agent was applied and polymerized just before the cementation of the indirect restoration; 2) Dual Bonding Technique: a first layer of the bonding agent was applied and polymerized just after preparation, and a second layer just before the final cementation and 3) Resin Coating Technique: a LVCR, was also applied and polymerized after the first layer and bef
