Exclusion criteria: Patients with indirect restorations in the upper and lower anterior region; patients who have a history of adverse reaction to peroxide; patients who use opioids or drugs that influence the neuro-sensory response; patients who have a pacemaker; patients with tooth stains (tetracycline, trauma, fluorosis and unknown etiology); patients with neurological diseases; patients with chronic or acute diseases; patients with exposed dental tissue; patients with dental sensitivity or with a history of treatment
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluate the chromatic alteration in different dental groups (lower incisors, upper incisors, canines and premolars). They will be verified by the chromatic alteration analysis method through the digital spectrophotometer Vita Easyshade, which presents the numbers through CIELab coordinates. We will see if all teeth show the same behavior of chromatic alteration in the previously established times (3 whitening sessions).;To evaluate the presence of tooth sensitivity in different dental groups (lower incisors, upper incisors, canines and premolars). They will be checked by the sensitivity analysis method using the TSA II Metod equipment, which provides the change in the thermal sensation threshold, in temperature, that occurred in the patient during the lightening sessions. In addition, questionnaires will be applied where the patient will inform the presence or absence and intensity of tooth sensitivity through score numbers. Together, using the TSA II Metod equipment, the VOCs test will be performed, in which, when applying a cold thermal stimulus to the patient's dental element, it will reproduce the presence or absence of sensitivity, the intensity and the time elapsed for the thermal perception in digital sensation reproduction equipment. We will observe the behavior of the sensitivity in different dental elements, which present different anatomical and functional characteristics. | — |
