Design outcomes
Primary
| 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) | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome: The color difference between the initial condition and 1 month after bleaching will be assessed using the Vita Classical and Vita Bleachedguide color scales and also with the Vita Easyshade spectrophotometer. The data will be presented in the form of means and standard deviations. No interference is expected from the application of bleaching gel based on 40% carbamide peroxide in the results of bleaching treatment with respect to hydrogen peroxide at 35% | — |
