The aim of this study was to evaluate the influence of time of application of antioxidant agents on the bond strength to bovine enamel after bleaching by light emitting diode. Twenty two bovine incisors were used, on which the vestibular surfaces were flattened and divided into four experimental groups (n = 15) according to each antioxidant agent, with two(More)
Although in-office bleaching has been proven successful for bleaching teeth, controversy exists from morphological alterations in enamel morphology due to mineral loss and tooth sensitivity. This preliminary study aimed to evaluate the efficacy of a novel in-office tooth bleaching technique modified with a casein phosphopeptide-amorphous calcium phosphate(More)
This in vitro study sought to evaluate both the bleaching potential and changes to average surface roughness (Ra) of enamel after brushing with a dentifrice. Fifty-four enamel specimens (4 x 4 x 2 mm) were divided into 3 groups (n = 18) and treated with 1 of 3 dentifrices: 1 with calcium peroxide, and 2 without. The samples were submitted to 20,000 brushing(More)
