Eligibility

Inclusion criteria

Inclusion criteria: Age between 18 and 25 years; good oral and general health; absence of gingivitis, periodontitis, dental mobility and diabetes; all teeth between the first right upper premolar and the left first maxillary premolar should be present and free of caries and restorations; the maxillary central incisors should be A3 or more saturated.

Exclusion criteria

Exclusion criteria: Patients who have had a previous dental bleaching procedure; Pregnant and lactating women; Patients who have teeth with severe internal discoloration (resulting from stained with tetracycline, fluorosis or endodontic treatment) Patients with potentially sensitive teeth such as gingival recession, dentin exposure and poor enamel formation Patients who report sensitivity existing at the time of anamnesis.

Design outcomes

Primary

MeasureTime frame
The degree of sensitivity during and after office dental whitening is expected to decrease. The evaluation will be done by marking scores ranging from 0 to 4, used in the dental literature and recommended in the works of Kossatz et al.—

Secondary

MeasureTime frame
Influence of the desensitizing gel previously applied to the bleaching gel on the final color result, by means of the initial and final color comparison, from the Vitapan Classical color scale (Vita, Bad Säckingen, Germany)—
