Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome: Number of patients reporting pain after bleaching agent treatment through self-report. This number will be transformed into percentage of patients with pain and will be called absolute risk of dental sensitivity after bleaching with 4% hydrogen peroxide.;The intensity of dental sensitivity will be evaluated using a 5-point numerical rating scale (NRS 0-4) and visual analog scale (VAS 0-10) and will be presented as mean and standard deviation for 21 days of treatment. | — |
Secondary
| Measure | Time frame |
|---|---|
| The teeth shade of each participant at the beginning of the study, during treatment (after the first, second and third weeks of bleaching treatment) and one month after the whitening will be recorded through subjective and objective evaluation. For subjective evaluation of color, two color guides will be used: Vita Classical (Vita Zahnfabrik) and Vita Bleachedguide 3D-MASTER (Vita Zahnfabrik). For objective color evaluation, a spectrophotometer (Easyshade, Vita Zahnfabrik) will be used.;At the beginning and end of the study, questionnaires will be applied to assess aesthetic self-perception - PIDAQ Psicossocial Impact of Dental Aesthetics Questionnarie). | — |
