Paper Abstract

The study describes a diode system which activates a home-bleaching agent for discolored teeth. The techniques involve pastes utilizing 16 % hydrogen and carbamide peroxide. Two different laser diodes operating at 445 nm and 1.7 um were used. The exposition power densities used were up to 10 W/cm2. For bleaching, stereolithographic models and trays were prepared. Bleaching technique was activated laser irradiation lasting for 100 s, bleaching. After the bleaching process, the enamel surface was with the scanning electron microscope. This process resulted in a 2-3 shade change measurement in one treatment.
