ABSTRACT
Objective: The aim of this study was to compare dental color changes after a one-session tooth bleaching procedure using 35% hydrogen peroxide with and without hybrid light (LED/diode laser) activation. Material and Methods: 20 volunteers were included in a split-mouth controlled clinical trial. A 35% hydrogen peroxide gel was applied directly on the buccal surface and adjacent areas of all upper anterior teeth. The six teeth were divided into two groups: the upper right incisors and canine were submitted to the tooth bleaching with the gel and the hybrid light (LED/diode laser) while the left incisors and canine were submitted to tooth bleaching with only the gel. Dental color was measured with a visual color scale and a spectrophotometer at five different moments: initial appointment, immediately after prophylaxis, and 14, 30 and 180 days after bleaching. Results: The comparison between the results of both treatments (with and without LED/laser) did not show any statistically significant differences (p > 0.05; Wilcoxon test) neither for objective (spectrophotometer) nor for subjective evaluations (visual color scale). Conclusion: The results of the present study showed that there are no differences in dental color changes between dental bleaching with gel and LED/Laser activation and dental bleaching with only gel.
