Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the bleaching efficacy, using the Vita Classical, Vita Bleachedguide (?SGU) and VitaEasyshade spectrophotometer (?Eab, ?E00 and ?WID) scales of volunteers submitted to different in-office bleaching protocols (two sessions with 2 applications of 20 minutes, 1 application of 30 minutes or 1 application of 40 minutes). | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate the absolute risk and the intensity of dental sensitivity, through the Visual Analogue Scale (VAS) of volunteers submitted to different in-office bleaching protocols.;To evaluate the absolute risk and intensity of gingival irritation, using the Visual Analogue Scale (VAS) of volunteers submitted to different in-office bleaching protocols.;To evaluate the aesthetic self-perception before and after bleaching, using the Orofacial Aesthetics Scale (OAS) of volunteers submitted to different in-office bleaching protocols.;To evaluate the impact of oral condition before and after bleaching, using the Brazilian version of the Oral Health Impact Profile (OHIP-14) of volunteers submitted to different in-office bleaching protocols | — |
