| English abstract | 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 |

MATERIAIS E MÉTODOS: Os dentes foram seccionados em forma de palitos com tamanho de 1.0 ± 0,2 mm2 e tracionados com velocidade de 1mm/min. Os tipos de fraturas foram verificados utilizando o microscópio óptico. RESULTADOS: Os sistemas adesivos (One Up Bond FTM, All Bond 2TM, One Step PlusTM, Adper Prompt L-PopTM, One StepTM, Single BondTM e Clearfil SE BondTM apresentaram os maiores valores de resistência adesiva em dentina. Os sistemas Scotchbond MPTM, Prime&Bond NTTM e ExciteTM apresentaram menor resistência. CONCLUSÃO: Os sistemas autocondicionantes e os convencionais apresentaram maior resistência adesiva em dentina. Os sistemas Scotchbond MPTM, Prime&Bond NTTM e ExciteTM apresentaram menor resistência adesiva. As fraturas adesivas representaram 69% do total das fraturas |
