抄録

The purpose of this study was to observe the resin-dentin interface of four one-bottle self-adhesives by FESEM.Dentin discs were prepared from freshly extracted human third molars and the surfaces were ground with #600SiC paper under running water. These surfaces were treated with four commercially available one-bottle selfadhesives (Absolute; Dentsply Sankin, G Bond; GC, i Bond; Heraeus Kulzer, and Clearfil tri-S Bond; Kuraray Medical), respectively following the manufacturer's directions, and then treated surfaces were restored with a flowable composite resin (Revolution Formula2-Kerr; Sybron Dental) and light cured. Specimens were longitudinally sectioned through the resin-dentin interface and stored in water or not in water for1day and1month. After each period, the specimen was argon ion (Ar-ion) beam etched for30or60seconds with1kV acceleration voltage (EIS-200ER; Elionix), and the resin-dentin interface was observed by FE-SEM (ERA-8900FE; Elionix). The bond layer of all materials showed a rough surface after Ar-ion etching. The morphological structure of the bond layer observed depended on the adhesive systems. However, all materials showed that there were no morphological differences between1day and 1 month storage. It was suggested that the morphological structure of the four commercially available one-bottle self-adhesives was stable after1month water storage.
