The application is successful in clinical in vive and in vitro. The Brightener III with low-viscosity and high mobility enhanced the relative wear resistance of the four evaluated materials when comparing with those unprotected groups. Therefore, tooth-colored restorative materials with the application of Brightener III could improve their mechanical properties effectively. The purpose of this in vitro study was to evaluate the effect of colour relapse on bleaching surface with surface protector after power bleaching, when used for a short period of time and over a prolonged period of time. The mechanism of colour relapse after bleaching will be discussed clearly. In addition, the various bleaching source is also devoted to compare together.
