Influência do uso da proantocianidina na resistência de união de sistemas adesivos: revisão integrativa.

Abstract

Introduction: Proanthocyanidin (PA), a grape seed extract, has been used as an inhibitor of dentin matrix metalloproteinases, helping to increase the longevity of composite resin restorations. Objective: To compile a literature review table on the influence of the use of proanthocyanidin on the bond strength of adhesive systems. Methodology: A bibliographic search was carried out in the following databases: PubMed, Web of Science, Scopus, and in the Virtual Health Library (BVS) databases, using the following descriptors: “proanthocyanidin”, “bond strength” and “adhesive system”, from 2015 to 2021. All in vitro studies were considered, 18 articles were chosen to be listed, which addressed the literature sought. Results: 77% of the in vitro studies studied here presented results affirming their efficiency in improved bond strength and increased longevity of dental restorations, and only 23% of the studies did not present significantly relevant results. Conclusion: Although the effectiveness of PA is proven, there is no protocol. mode of incorporation of proanthocyanidin, whether its concentration, restorative step or the means of incorporation. The form of incorporation of PA during the r step can directly affect its performance, and even with several in vitro studies being carried out in the last seven years, we still do not have longitudinal clinical studies that give clinically solid foundations, and studies are still necessary, as its exact protocol is still something to be studied and sought after.
