Exclusion criteria: Having received previous dental bleaching ; restorations on the anterior teeth; pregnant or nursing women; having teeth darkened by tetracycline, fluorosis or endodontic treatment; patients with teeth grinding; having non-carious cervical lesion; and dentin hypersensitivity.

Design outcomes

Primary

MeasureTime frame
Absence of postoperative sensitivity in experimental groups 1 and 2, verified by sensitivity tests (thermal and mechanical stimuli), after 4 weeks. It is not expected interference in results of the bleaching treatment in the groups assessed, verified by spectrophotometry, from the observation of the increase in the value of Delta E (indicating the success of the bleaching treatment), after 4 weeks.

Secondary

MeasureTime frame
Absence of postoperative sensitivity in experimental groups 1 and 2, verified by sensitivity tests (thermal and mechanical stimuli), after 1, 2 and 3 weeks.
