Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome: Number of patients that report spontaneous pain in any moment of the bleaching protocol and up to 48 h post-bleaching, through self-report. This number will be presented as percentage of patients with tooth sensitivity and will be named absolute risk of tooth sensitivity. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome: The intensity of tooth sensitivity will be evaluated through the records made by patients with the use of numerical scales of 5 points (NRS 0-4) and visual analogue scale VAS (0-10). Values are presented as mean and standard deviation for the different evaluated periods (during tooth whitening by 1 h, 1 h to 24 h and 24-48 h post-bleaching).;Expected outcome: The difference in color between the baseline condition and 1 month post-bleaching will be assessed by Vita Classical and Bleachedguide Vita shade guide as well as with the Vita Easyshade spectrophotometer. The data will be presented as means and standard deviations. | — |
