The use of self-adhesive resin cement is being increased due to its convenience. The purpose of this study was to compare the shear bond strength, flexural strength, water sorption and solubility of various self-adhesive resin cements. Self-adhesive resin cement used in the experiment was Bifix SE(Bifix)) Bis Cem(Bis), ICem(ICem), MonoCem(Mono) and SmartCem(Smart). In order to measure the shear bond strength, bovine teeth was embedded in acrylic resin and ground until superficial dentin was exposed. Blocks using composite resin were produced(2.3 ㎜ in diameter × 2.2 ㎜ in height) and they were applied on bovine teeth with resin cement according to the manufacture"s instructions. Adhered sample were kept in 37℃ distilled water for 24 hours before experiment was done, the shear bond strength was measured by using a universal testing machine(Z020, Zwick, Dim, Germany) with cross-head speed of 0.75 ㎜/min. Specimens for the flexural strength was tested with the same cross-head speed. Then, water sorption and solubility were measured. The shear bond strength of self-adhesive resin cement were no significantly differences(p>0.05). In flexural strength, the Bifix SE(Bifix) was significantly higher than other groups, then there was SmartCem(Smart)(p<0.05). In water sorption, the SmartCem(Smart) was significantly lower than other groups, then there was Bifix SE (Bifix)(p<0.05). BisCem(Bis) was significantly higher than other groups(p<0.05), and the MonoCem(Mono) was not significant difference (p>0.05). In solubility, the Bifix SE(Bifix) was lowest rate(p<0.05), and Smart Cem(Smart) and BisCem (Bis) were no significant differences(p>0.05). In this study, Smart Cem(Smart) and Bifix SE(Bifix) high flexural strength, low water sorption and solubility, so is a clinically favorable self-adhesive resin cement.
