Abstract

The aim of this study was to evaluate changes in mineral content of bleached enamel and the infl uence of post-bleaching time interval on the marginal seal of class V composite restorations. Forty bovine incisors were restored using Magic Bond adhesive and Fill NT Premium composite according to the manufacturer’s instructions. The teeth were randomly divided into 4 experimental groups (n = 10): G1, not bleached (control); G2, bleached and immediately restored; G3, bleached and restored after 7 days; G4, bleached and restored after 14 days. The mineral content was evaluated by QLF (quantitative light-induced fl uorescence). The microleakeage scores were analyzed by 3 calibrated examiners. There was no statistical difference between the groups regarding change of the bleached mineral substrate (repeated measures ANOVA, p = 0.2130) and the microleakage scores (Friedman, p = 0.2551). It was concluded that the bleaching protocol used is safe because it does not cause mineral changes in the bleached enamel, and that the post-bleaching time interval observed before performing adhesive procedures did not affect the marginal seal of composite resin restorations.
