This study evaluated the change of color and the microhardness according to time-out using the office bleaching with in vitro test after bleaching one time 1 day per week, total three times, for the control group and three times per 1day for the experimental group. L* was increased in both groups. Group 1 showed a significant increase statistically between before and after tooth whitening (p＜0.05). Group 2 showed a significant increase statistically between before and after tooth whitening (p＜0.05). ∆E* was huge in both groups. In group 1, it was great in terms of statistical significance between 1 day and 7 days after tooth whitening (p＜0.05). In group 2, it was the greatest between before and 1 day after tooth whitening and was significant statistically as well (p＜0.05). Vickers hardness number (VHN) decreased in both groups. In group 1, VHN decreased over time and the difference was significant statistically (p＜0.05). In group 2, VHN decreased over time and the difference was significant statistically (p＜0.05). Percentage microhardness loss was great in both groups. In group 1, it was the greatest between 1 day and 7 days after the treatment, and it was significant statistically (p＜0.05). In group 2, it was the greatest between before and 1 day after the treatment, and it was significant statistically (p＜0.05). Put together, the more frequent tooth whitening a day is, the longer the period of tooth whitening when applying the same frequency, the greater color change was, however the microhardness decreased, in regard to the results over time using 15% hydrogen peroxide tooth whitening product for professionals.
