The purpose of this research was to evaluate the influence of a led/laser system-with 6 leds of 470nm and 3 infra red laser diodes of 830nm and 0,2W of power-over 35% (Lase Peroxide 35% Sensy, DMC Equipment) and 25% (Lase Peroxide 25% Sensy, DMC Equipment) hydrogen peroxide gel in 10 volunteers. The bleaching agents were applied in thickness next to 1 mm to each arch. The led/laser set was applied for 1 minute, interpolated by 1 minute without luminous irradiation, for 3 times. Then, the gel remained for more 4 minutes and this protocol was repeated for three times in the right half-arch. in the left half-archs there was no luminous irradiation, once the gel was protected by a dental archs divisor plate. The gel remained for the same time as in the right half-archs (10 minutes for 3 times). After 7 days, the volunteers returned for evaluation regarding perception of sensibility and bleaching degree. According to the researcher and patients evaluation, through questionnaire, there wasn't noticeable difference in bleaching degree between the right and left half-archs (with and without luminous system application respectively), in both dental bleaching concentrations (25 and 35%). It was also reported no difference in the degree of sensibility among the half-archs, as well.
