Inclusion criteria
Inclusion criteria: Patients aged between 18 and 50 years; both genders; with good oral and general health; have their maxillary anterior teeth free from restorations and carious lesions; canines with color A2 or darker according to the Classical Vita scale (Vita Zahnfabrik, BadSäckingen, Germany); to agree with the free and informed consent form
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome: It is expected to find a reduction in tooth sensitivity after using the experimental whitening gel containing the composite, at some point up to 48 hours after each session, by using the VAS visual analog scale (0 to 10). Percentage of patients with pain will be called absolute risk of tooth sensitivity. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome: It is expected to find a reduction in the intensity of tooth sensitivity after using the experimental whitening gel containing the composite, at some point up to 48 hours after each session, by using the VAS visual analog scale (0 to 10). Percentage of patients with pain will be called absolute risk of tooth sensitivity. Values will be presented as mean and standard deviation;Expected outcome: The color difference between the two groups is expected to be effective, assessed at baseline and 1 month after bleaching by means of the Viita Classical scales and the Bleachedguide Vita shade guide, as well as with the Vita Easyshade spectrophotometer. Data will be presented as means and standard deviations | — |
