In all-in-one adhesive systems, because of the low etching ability of acidic monomers, the thick smear layer may affect the bonding efficacy of the adhesive systems. In this study, the effect of grinding surface on microtensile bond strength to dentin of 2 all-in-one adhesive systems, i Bond and G-BOND, was investigated. Dentin surface was ground with three different courses of SiC papers. In the results, the etching ability of the adhesive systems was weak strong and the grinding surface had little effect on the bond strength to dentin. When the rougher surface was bonded, numerous voids were exposed on the fractured surfaces of the adhesive layer. It was suggested that the grinding surface had an effect of the bond strength to dentin in i Bond, although structural faults were formed at the bonding interface when the rougher surface was produced.
