Inclusion criteria
Inclusion criteria: Minimum age of 18 years; of both sexes; good general and oral health, without systemic diseases that may interfere with dental whitening; absence of periodontal disease, gingival recession or carious lesions in anterior teeth; upper canines with Whiteness Index for Dentistry (WID) shade less than 20 equivalent to A2 or darker, according to the Vita Classical scale (Vita Zahnfabrik, Bad Säckingen, Germany); absence of restorations in anterior teeth, ensuring an accurate analysis of the color change; availability to attend consultations and follow the experimental protocol
Exclusion criteria
Exclusion criteria: Previous history of dental whitening; pre-existing dentin hypersensitivity, reported by the participant or identified during screening; continuous use of analgesic or anti-inflammatory medications, which may interfere with the perception of dental sensitivity; use of orthodontic appliances, dentures or restorations in anterior teeth, as they may influence the assessment of color; previous endodontic treatment in anterior teeth, which may affect the response to whitening; presence of severe tooth discoloration, including severe fluorosis, pulpless teeth or stains resulting from the use of tetracycline; visible cracks in tooth enamel, which may compromise the response to whitening; pregnancy or lactation, due to the lack of studies on the safety of whitening in this population; smoking or bruxism, which may influence color stability and oral health
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Monitor the evolution of color change over time in patients undergoing home whitening with 10% carbamide peroxide, identifying the saturation point, that is, the moment at which the color variation becomes clinically insignificant. | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate the evolution of tooth color throughout home whitening treatment using 10% carbamide peroxide, using spectrophotometry (Vita Easyshade) and visual scales (Vita Classical and Vita Bleachedguide 3D-MASTER).;Assess dental sensitivity throughout treatment, analyzing the frequency, intensity and duration of symptoms reported by participants.;Analyze the occurrence of gum irritation associated with prolonged use of the whitening gel, identifying its frequency, intensity and duration.;Examine participants' perception of the treatment, using a questionnaire that assesses aesthetic satisfaction, impact on quality of life and comfort during the whitening process. | — |
