Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Minimum age of 18 years; both sexes; good general and oral health, without systemic diseases that could interfere with teeth whitening; absence of periodontal disease, gingival recession, or carious lesions in anterior teeth; upper canines with a Whitening 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: Prior history of teeth whitening; pre-existing dentin hypersensitivity, reported by the participant or identified during screening; continuous use of analgesic or anti-inflammatory medications that may interfere with the perception of tooth sensitivity; use of orthodontic appliances, dental prostheses, or restorations in anterior teeth, as they may influence the color assessment; previous endodontic treatment in anterior teeth, which may affect the response to whitening; presence of severe tooth discoloration, including severe fluorosis, teeth without pulp, or stains resulting from the use of tetracycline; visible cracks in the dental enamel that may compromise the response to whitening; pregnancy or lactation, due to a 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 |
|---|---|
| The study aims to analyze the influence of different application times (30 minutes and 60 minutes) of 22% carbamide peroxide on the risk of tooth sensitivity, verified through self-reporting by participants, by comparing the proportion of individuals who reported tooth sensitivity (yes/no) in each protocol throughout the treatment period | — |
Secondary
| Measure | Time frame |
|---|---|
| The study aims to examine the impact of different application times (30 minutes and 60 minutes) of 22% carbamide peroxide on the intensity of dental sensitivity, verified through self-reporting by participants using a pain intensity scale, based on a comparison of the average sensitivity scores obtained in each protocol throughout the treatment period;The study aims to examine the impact of different application times (30 minutes and 60 minutes) of 22% carbamide peroxide on the absolute risk and intensity of gingival irritation, verified through participant self-report and standardized clinical assessment, by comparing the proportion of participants who presented gingival irritation (yes/no) and the average intensity scores observed in each protocol during treatment;The aim is to evaluate the whitening efficacy of different application times (30 minutes and 60 minutes) of 22% carbamide peroxide, verified through subjective and objective evaluation methods, based on the analysis of color variations between the initial and final evaluations, expressed by color guide scores (subjective evaluation) and by colorimetric indices (objective evaluation), comparing the two application protocols;The aim is to evaluate patients' aesthetic perception after treatment, verified through the application of a structured self-report questionnaire, based on the analysis of satisfaction scores with dental appearance and the perceived impact on quality of life, comparing the values ??obtained before and after treatment | — |
