The aim of this study was to evaluate microtensile bond strength (μ-TBS) and failure mode of indirect composite restorations bonded to dentin using different combinations of Resin-Coating (RC) after thermal and load cycling. Thirty and distal surface). The 70 cavities were distributed in 7 groups according to the coating materials: G1:Etch-rinse 2steps (SB2); G2:Etch-rinse 2steps/Hydrophobic-monomer (SB2/B); G3:Etch-rinse 2steps/Flowable composite resin (SB2/FL); G4:Self-etch 1step (CS3); G5:Self-etch 1step/Hydrophobic monomer (CS3/B); G6:Self-etch1step/Flowable composite resin liner (CS3/PL), G7:Self-etch 2step/Flowable composite resin liner (CSEB/PL). The cavities were molded with a using the Sinfony composite system (3M/ESPE) and were cemented with resin luting cement (Rely X ARC system). After 24 hours, the teeth were submitted to thermocycling (2,000C/5-55°C) and load cycling (250,000C/30N). After, the restored teeth were sectioned in to beams and μ-TBS were measured. The data were analyzed with ANOVA and Tukey test (p<0.05). In addition failure mode pattern was determined by scanning electrical microscopy. Bond strength were mode exhibited dentin exposure. The groups CSEB/PL and CS3/B showed the highest values of bond strength and the failure mode reveal CSEB/PL exhibited better performance since doesn’t present any fracture kind A.
