Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1: 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 treatments (activated charcoal powder, activated charcoal toothpaste, conventional toothpaste and 10% carbamide peroxide). It is expected that whitening efficacy will depend on the treatment performed.;Outcome found 1: Activated charcoal products have no significant effect on color change when compared to 10% carbamide peroxide. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome 2: The intensity of dental sensitivity will be evaluated using the VAS analogue visual scale (0-10). It is expected that sensitivity will depend on the treatment performed.;Outcome found 2: No significant difference was found among the groups regarding to sensibility intensity.;Expected outcome 3: To assess the acceptability of the treatments carried out by the research participants. Acceptability is expected to depend on the treatment performed.;Outcome found 3: Activated charcoal-based products are less acceptable than 10% carbamide peroxide.;Expected outcome 4: The effect on enamel roughness will be evaluated by means of replicates and the effect will be according to the treatment performed.;Outcome found 4: Products based on activated charcoal promote an increase in the roughness of dental enamel, regardless of presentation form (powder or toothpaste). ;Expected outcome 5: Significant differences in the impact of oral health on quality of life are expected depending on the treatment, using the Oral Health Impact Profile-14 questionnaire (OHIP-Esthetics) and the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ);Expected outcome 6: To evaluate the aesthetic self-perception, using the Orofacial Aesthetics Scale (OAS) of volunteers submitted to protocols (activated charcoal powder, activated charcoal toothpaste, conventional toothpaste and 10% carbamide peroxide).;Outcome found 6: OES questionnaire, significant increase only in the tooth color domain for the 10% carbamide peroxide. | — |
