Influência do ascorbato de sódio a 10% na resistência de união entre resina composta e dentes submetidos ao clareamento dental: revisão sistemática

Abstract

Introduction: Tooth whitening is one of the most common clinical procedures in the dental office, and its demand can be accompanied by restorative procedures. Because of the changes to the enamel surface caused by whitening, the use of reversal agents such as Sodium Ascorbate may be indicated. Objective: To evaluate the influence of the use of Sodium Ascorbate a 10% after bleaching procedures on increasing the bond strength between enamel and resin restorations to be made. Methodology: To construct this Systematic Review, we used the Pubmed, Virtual Health Library and Scopus databases and the keywords with the following connectors: “tooth bleaching AND AND composite resin AND antioxidants”. Of the 121 articles initially found, after the inclusion and exclusion criteria, only 19 were used for this review. Results: It was possible to understand that tooth whitening is capable of reducing the bond strength of whitened enamel, regardless of which bleaching agent has been used. For this reason, the reversal agent Sodium Ascorbate a 10% may be a good strategy for re-establishing resistance and thus being able to perform composite resin restorations without the need for conventional waiting times. According to the articles analyzed, the best way to use this antioxidant is as a 10% solution for 10 minutes. In addition, compared to sodium ascorbate, other antioxidants were also effective being Grape Seed extract 5% and Green Tea 10%. Conclusion: Among the studies analyzed, the use of the reversal agent sodium ascorbate proved to be particularly effective when applied in solution form. However, it is important to note that other antioxidants have also shown promising results in laboratory research. Therefore, further studies are needed to translate the in vitro findings into clinical practice in order to validate their efficacy and safety under real conditions.
