Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1: It is expected to find a reduction in tooth sensitivity after using hydrogen peroxide whitening gel in the superior arch, at some point up to 48 hours after each session, by using the VAS visual analog scale (0 to 10). Percentage of patients with pain will be called absolute risk of tooth sensitivity.;Outcome found 1: A reduction in tooth sensitivity was found after the use of hydrogen peroxide whitening gel in the upper arch, after each whitening session, when assessed using the VAS visual analog scale (0 to 10). The percentage of patients with pain, called absolute risk of tooth sensitivity, was 75%. | — |

| Expected outcome 2: It is expected to find a reduction in the intensity of tooth sensitivity after using the hydrogen peroxide whitening gel in the superior arch, at some point up to 48 hours after each session, by using the VAS visual analog scale (0 to 10). Percentage of patients with pain will be called absolute risk of tooth sensitivity. Values will be presented as mean and standard deviation.;Outcome found 2: A reduction in the intensity of tooth sensitivity was found after the use of hydrogen peroxide whitening gel in the upper arch, after each session, when assessed by the VAS visual analog scale (0 to 10).;Expected outcome 3: The color difference between the two groups is expected to be effective, assessed at baseline and 1 month after bleaching by means of the Viita Classical scales and the Bleachedguide Vita shade guide, as well as with the Vita Easyshade spectrophotometer. Data will be presented as means and standard deviations.;Outcome found 3: Effective color change was found in both groups when assessed at baseline and 1 month after bleaching using the Vita Classical and Vita Bleachedguide scales, as well as with the Vita Easyshade spectrophotometer. No differences were found between the two groups. | — |
