Bonding performance of two experimental self-etching adhesives to tooth substrate.

抄録

In last decade, the two-step self-etching adhesive technology led to the development of all-in-one systems. All-in-one systems are undoubtedly the most user-friendly adhesives, but have been associated with lower effectiveness as compared to two-step self-etching adhesives. It has been reported that the double-application of some all-in-one bonding systems were successful to increase the bond strength to sound dentin. The purpose of this study was to examine the adhesion of two type experimental self-etching adhesives to enamel and dentin and to evaluate the effect of double-application of three all-in-one adhesives on bond strength.
