title: Critical appraisal. Reversal of compromised bonding after bleaching.
abstract: Bleaching with peroxide agents compromises the adhesion of resin-based materials to enamel and dentin. The problem is likely caused by delayed release of oxygen from the teeth that inhibits resin polymerization at the interface. The typical method for avoiding problems with bonding to bleached teeth is simply to delay the bonding procedure for a week or two after bleaching. However, there is evidence that bonding can be done immediately if bleaching is followed by the application of an antioxidant. This Critical Appraisal reviews some of the published reports on the reversal of compromised bonding after bleaching via the use of antioxidants such as sodium ascorbate.
