Abstract: This study aimed to evaluate the bonding performance of a new one-step self-etching adhesive system containing a novel hydrophilic amide monomer. Clearfil Universal Bond Quick (CUB) and Clearfil Megabond 2 (CMB) were used as the one-step and two-step adhesive systems, respectively. Flat dentin surfaces of human premolars were exposed using #600 SiC (silicon carbide) and bonded with the respective adhesives of each system. The teeth were sectioned to obtain beams (1 mm x 1 mm) after 24 h of water storage. The mean bond strength and standard deviations (MPa) on an occlusal surface were as follows: CUB: 45.9 +/- 19.7 and CMB: 67.9 +/- 25.3. The values for cervical ones were CUB: 56.0 +/- 20.3 and CMB: 67.6 +/- 16.0, respectively. In both conditions, the microtensile bond strength (mu TBS) value was lower than that of CMB. As seen during the microscopic observation, no adhesive failure was observed after mu TBS testing because CUB formed a firm and tight adhesive interface.
