EFFECT OF WETTING AGENTS ON THE HANDLING OF COMPOSITE RESIN: integrative review

Abstract

However, its high viscosity can hinder insertion and sculpting, leading to the increasing use of wetting agents or modeling liquids developed to facilitate manipulation and placement, improve marginal adaptation, and reduce resin adhesion to instruments. Despite their routine application, uncertainty remains regarding the effects of these agents on the mechanical and optical properties and the longevity of restorations. The aim of this study was to evaluate, through an integrative review, the impact of wetting agents on the handling of composite resins and their properties. The study followed PRISMA guidelines, using the PICO strategy to formulate the research question. The search was conducted in the PUBMED/MEDLINE, Scielo, and EBSCO databases, including articles published in the last 10 years. In vitro studies, literature reviews, and clinical research investigating the use of different wetting agents in the manipulation of composite resins were considered. Although some studies demonstrate functional and aesthetic advantages, others warn of negative impacts that may compromise the durability of restorations. The lack of consensus in the literature reinforces the need for further research, especially long-term clinical studies. The use of wetting agents can optimize the handling of composite resins but should be adopted with caution, considering possible alterations in the material’s properties. Clinical decisions should be based on updated scientific evidence and the individual assessment of each case, aiming to preserve the aesthetic quality and longevity of restorations.
