Interventions
This study is a randomized, controlled, double-blind clinical trial with five arms, involving 100 eligible participants who will be randomly allocated into five groups (n = 20 per group). All particip
Group 2 (G2) will receive whitening with 35% hydrogen peroxide and Gluma Desensitizer application
Group 3 (G3) will have whitening with 35% hydrogen peroxide and low-level laser application
Group 4 (G4) will be treated with 35% hydrogen peroxide, potassium nitrate, and low-level laser
and Group 5 (G5) will receive whitening with 35% hydrogen peroxide, Gluma Desensitizer, and low-level laser. Participant allocation will be conducted randomly using a randomization software to ensure

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected Outcome: To evaluate dental sensitivity and whitening effectiveness using different desensitizing methods. The method used to verify the expected outcome will be assessed through sensitivity measurements and colorimetric analysis before and after the intervention. Parameters such as numerical scores for sensitivity and shade changes (?E) will be used to determine if the outcomes were achieved. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected Outcome: To evaluate the quality of life and psychosocial impact of dental aesthetics before and after the intervention. The method used to verify the expected outcome will involve the application of validated questionnaires measuring the participants' perception of their dental aesthetics and its impact on their quality of life. Parameters such as scores from the OHIP (Oral Health Impact Profile) and the PIDAQ (Psychosocial Impact of Dental Aesthetics Questionnaire) will be analyzed to assess changes pre- and post-intervention. | — |
