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 ;Observed outcome: The same expected outcome. No change in the outcome was done. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome: The intensity of tooth sensitivity will be assessed using the numeric 5-point scale (NRS 0-4) and the visual analogue scale (VAS 0-10) and will be presented as means and standard deviations in different periods (during dental bleaching, up to 1 h, 1 h to 24 h and 24 h to 48 h post-bleaching).;Observed outcome: The same expected outcome. No change in the outcome was done.;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;Observed outcome: The same expected outcome. No change in the outcome was done. | — |
