A newly designed one-bottle/one-step type resin bonding system based on the conventional “Xeno” technology has been developed by Dentsply Sankin Co. Ltd. The purpose of this study was to evaluate the bond strength, marginal adaptation with this brand-new system and to observe the interfacial ultrastructure under the FE-SEM. Firstly, the tensile bond strength to bovine tooth was measured after 24 hours. Secondly, the resin-tooth interface was observed under the FE-SEM after the Ar-ion beam etching for 35s using the flat enamel/dentin surfaces or cavities after dentin caries removal of the human extracted teeth. In addition, the microleakage assessment was performed after thermo-cycling for 10, 000 cycles. The tensile bond strength of this system was higher than 20MPa to the enamel and about 15MPa to the dentin, which was not significantly different from Clearfil Mega Bond. The junction between the resin and the tooth tissue was very tight, and in the superficial dentin layer, the hybrid layer about 0.5-1.0μm thick was clearly observed. And this system revealed comparatively good marginal adaptation after thermo-cycling. It was suggested that the brand-new system will be promising as a next generation resin bonding system.
