Research Abstract

We studied the effect to bond strength to enamel of the type of the adhesion system and the bleaching agents、antioxidant. Bond strength decreased immediate after bleaching with all adhesion systems、but bond strength improved by an underwater soak for 2 weeks or antioxidant treatment (20wt% ascorbic acid or 10wt% tocopherol).
Additionally、we studied morphologic effect on enamel by the type of the bleaching agents. but there are no findings by the observation with the scanning electron microscope.
