<CLINICAL>Clinical results of vital tooth bleaching : 1. In-office bleaching

P(論文)In recent years, demand for esthetic dentistry has grown, particularly with respect to treatment of discolored anterior teeth. Tooth discoloration and pigmentation can be treated by polishing or bleaching the tooth, or by laminate veneering. Bleaching is widely used, since it allows esthetic restoration without removal of the tooth surface. However, its tooth-bleaching efficacy is often assessed in a subjective manner. This report describes the use of in-office bleaching of tetracycline-induced tooth discoloration and yellowed teeth using Hi-Lite^ and Power Gel^, respectively, and objective assessment of efficacy. In both cases, excellent improvement in tooth color was noted, with a color difference (AE) from baseline of 5.8-6.5. These results support that in-office bleaching using Hi-Lite^ or Power Gel^ is a safe and efficacious method for the treatment of tooth discoloration.departmental bulletin pape
