In prior study, it concluded the 3rd generation light-activated resin composite surface protector (Brightener Ⅲ) was the best surface treatment material in power bleached teeth. The purpose of this study was to search for whether Brightener Ⅲ retards the initial color relapse after power bleaching. Aging test was conducted in tea solution after Brightener Ⅲ applied on bleached teeth surface. The colormeter was performed to investigate color differences (ΔE). Based on the results, color evaluation with or without Brightener Ⅲ under tea solution was significantly different (p＜0.05). It meant that Brightener Ⅲ as a surface protector, could retard the initial color relapse after power bleaching.
