Resumo


OBJECTIVE: To evaluate the microtensile bond strength of ten dentin adhesive systems. MATERIAL AND METHOD: Sixty human molars were cut to the dentine level and restored with a hybrid composite and one of the adeshive systems. Each teeth were sectioned to obtain sticks measuring 1.0 ± 0.2 mm2, which were then stressed at a crosshead speed of 1mm/min in a universal testing machine until failure. The failure modes were verified using optical microscopy. RESULTS: One Up Bond FTM, All Bond 2TM, One Step PlusTM, Adper Prompt L-PopTM, One StepTM, Single BondTM and Clearfil SE BondTM presented no statistically significant differences (p>0.05); the lowest bond strength values were obtained with Scotchbond MPTM, Prime&Bond NTTM and ExciteTM (p<0.05). CONCLUSION: The self etch primer systems and conventional systems exhibited the highest bond strength to dentin, except for Scotchbond MPTM, Prime&Bond NTTM and ExciteTM. Adhesive fractures accounted for 69% of the total fractures.
