Abstract

Objectives: The aim of this study is to compare the effectiveness of whitening mouthrinses on teeth previously whitened or not, exposed to food dyes. Material and Methods: Ninety specimens of enamel and dentin of 3 mm in diameter will be obtained from bovine incisors. The specimens will be stained for 14 days in broth staining. After staining, the specimens will be embedded in resin flow and the initial color reading will be performed by a spectrophotometer CM-2600d (Konica Minolta, Osaka, Japan). Forty-five specimens (Subgroups PC) will be submitted to whitening (Carbamide Peroxide 10%) for 14 days. Following they will be subdivided into 3 subgroups, with cycles of staining (5 min.) and mouthrinse (2min.) for 12 weeks, with subgroup PC-LI: Listerine Whitening Pre-Escovação; Subgroup PC-PL: Plax Whitening; Subgroup PC-AG: deionized water. LI, LP and AG subgroups will be submitted to the same mentioned cycles, but will not be submitted prior to bleaching. The color measurements will be performed after 4, 8 and 12 weeks of treatment with mouthrinse. Data will be collected and subjected to statistical analysis.
