Abstract: Objective To evaluate the dentin bonding strength and durability of a novel universal adhesive used in self-etch mode and etching-rinsing mode. Methods Three groups of dentin/composite resin bonding specimens were prepared, which received three kinds of dentin conditioning, including no treatment (control), Singlebond Universal in self-etch mode and in etching-rinsing mode. Micro tensile bond strength (MTBS) after 24 hours’ and 180 days’ water storage was tested. The three different dentin/composite resin bonding interfaces were observed by a scanning electron microscope. Results Statistical differences existed in the bonding strength among three groups both before and after aging, and the control group demonstrated the lowest bonding strength, while the other groups showed no significant differences. Artificial aging significantly decreased the bonding strength of the control group, while it exerted no effect on the other two groups. Conclusion Application of Singlebond Universal can demonstrate better dentin bond performance to composite resin in both self-etch mode and etching-rinsing modes.
