Antioxidant Agents on Bond Strength of Bonded Bleached Teeth: Literature Review
Lobo, Sofia Costa Lima / Caetano Santos, Inês / Delgado, António / Mendes, José João
Introduction: Bleaching agents may adversely affect the bond strength of composite resin bonded to the tooth surface when adhesive procedures are performed immediately after the bleaching treatment.
Objective: To review and to research in vitro studies that evaluate the effect of antioxidant agents on the bond strength of bonded bleached teeth. This review may answer the following question: "Do antioxidant agents have effect on bond strength of bonded teeth after bleaching?"
Methods: The research strategy was performed using the PubMed / MEDLINE electronic database, using the keywords: "antioxidant agent", "bond strength", "dental bleaching" and "composite restoration". Inclusion criteria included in vitro studies published between 2011 and 2017. The exclusion criteria consisted in systematic or narrative reviews and case studies. The selection process followed the PRISMA method, having been carried out by two independent reviewers.
Results: The preliminary search retrieved 57 studies. Of these, only 6 met the inclusion criteria. Most of these laboratory studies focused on the concentration and the time of application.
Conclusion: The use of antioxidant agents after bleaching neutralizes the deleterious effects of bleaching and increase the bond strength, closer to the usual values. However, this effect is dependent on the type of antioxidant, concentration and duration of the application.
Clinical Implications: The application of antioxidant agents could be an advantage for the clinical and for the patient because it will decrease the waiting time between the bleaching and restorative procedure, also decreasing the time required to complete the treatment.
