Abstract
Recently, one- or two-step self-etching adhesives that reduce the number of application steps have been widely used. To evaluate the adhesive properties of these systems, bond strength tests of the tooth structure have been done. It is well known that many factors affect the results of the bond strength test. ISO/TS11405: 2003 (E) has been proposed as an international standard for testing adhesion to the tooth structure. According to this standard, the procedure of resin composites filling methods is defined, but the types of resin composites are not established. The purpose of this study was to evaluate the influence of types of resin composites on the shear bond strength of self-etching systems. The shear bond strength test, flexural strength test and scanning electron microscopic (SEM) observation were performed, and the results were as follows: 1. The types of resin composites affected the shear bond strength. 2. Adhesive failure was predominantly observed in the debonded almost enamel specimens. There was a tendency toward differences in failure mode among the specimens with dentin. 3. There was a significant difference in flexural strength and elastic modulus between Clearfil AP-X (Kuraray Medical) and Solare (GC). The resin composite that possesses good mechanical properties showed high bond strength. 4. From the SEM observation, the morphological features of debonded specimens depended on the adhesive system.
