Background: This in-vivo study compares the outcome of vital teeth bleaching, with and without light.
Materials and Methods: A total of 40 subjects were selected based on an exclusion and inclusion criteria with a minimum shade of A2 (classical Vitapan shade guide and electronic easy shade). The subjects were split into two groups. Group 1: One session of in-office bleaching using 30% hydrogen peroxide, without light. Group 2: In-office bleaching using 30% hydrogen peroxide with light. Both groups were given prefabricated home bleaching disposable trays containing 8% hydrogen peroxide to be used for 3 days. A color stability was evaluated during a period of 1-year, at baseline initially before bleaching (T0), at 1 month (T1), 3 months (T3), 6 months (T6), and 12 months (T12). Subjects were given a sensitivity log sheet to report any sensitivity during treatment. Different statistical tests, Wilcoxon and Mann-Whitney were used to analyze the results.
Results: Teeth bleached appeared lighter when compared to baseline with and without light while when comparing the use of light to no light, no significant difference was registered.
Conclusion: The use of light is not mandatory for the success of in-office bleaching. |
