Resumo: Purpose: The aim of this study was to evaluate the microtensile bond strength of one monocomponent adhesive system (Single Bond – SB) and one self-etching adhesive system (XENO III – XN) in superficial (SD) and deep (DD) dentin. Methods: The occlusal surface of twenty sound human molars was sectioned in two levels: 1mm (SD) and 3mm (DD) below the cusps. The teeth were divided into four groups: G1 (control 1): SB and SD dentin, G2 (control 2): SB and DD dentin, G3: XN and SD dentin, and G4: XN and DD dentin. One composite block was built over these surfaces. The teeth were sectioned into four slabs, which were trimmed to hourglass-shaped specimens (n=20 specimens/group). Each specimen was subjected to microtensile bond testing at a crosshead speed of 0.5mm/min. Data were analyzed by ANOVA and Newman Keuls test. Results: Means (standard deviation) values were (in MPa): G1 = 15.84 (4.04)a; G2 = 13.84 (3.52)a; G3 = 8.76 (1.61)b; G4 = 8.64 (3.12)b. Conclusion: It may by concluded that different depth levels of dentin do not affect bond strength for the same material; SB showed the highest bond strength values in both dentin depths. Key words: Bonding agents; microtensile bond test; dentin depth

Metodologia: A face oclusal de vinte molares humanos hígidos foi seccionada em dois níveis: 1 mm abaixo das cúspides (DS) e 3 mm abaixo das cúspides (DP). Os dentes foram divididos em 4 grupos: G1 (controle 1): SB e dentina DS, G2 (controle 2): SB e dentina DP, G3: XN e dentina DS, e G4: XN e dentina DP. Um bloco de resina composta foi confeccionado sobre essas superfícies. Os dentes foram seccionados obtendo-se quatro corpos-de-prova em forma de ampulheta de cada dente (n=20/grupo). Os corpos-deprova foram submetidos ao ensaio de microtração à velocidade de 0,5mm/min. Os dados foram analisados por ANOVA e teste de Newman Keuls. Resultados: As médias (desvio-padrão) foram (em MPa): G1 = 15,84 (4,04)a; G2 = 13,84 (3,52)a; G3 = 8,76 (1,61)b; G4 = 8,64 (3,12)b. Conclusão: Conclui-se que diferentes níveis de profundidade dentinária não afetaram a resistência de união para o mesmo material; SB mostrou os maiores valores em ambas as profundidades dentinárias.
