Impacto da manipulação de resinas compostas com luvas de procedimento sobre suas propriedades mecânicas: uma revisão sistemática

Abstract

Objectives: To perform a systematic review to evaluate the impact of handling composite resin with a procedure glove on the mechanical characteristics of direct restorations. Materials and methods: The PRISMA guidelines for systematic reviews were followed. Experimental studies that evaluated the effect of glove-based composite resin manipulation on the mechanical characteristics of direct restorations were selected. The literature search was performed on September 11, 2024, in the following databases: MEDLINE via PubMed, SCOPUS, Cochrane Library, VHL Regional Portal, and Open Grey Literature. To analyze the risk of bias, this study followed a scoring system adapted from systematic reviews focusing on in vitro studies. Materials and methods: A total of 105 studies were found (94 were removed after removing duplicates and reading the title and abstract). Only 8 articles were selected for qualitative analysis, of which 1 was excluded because it met one or more exclusion criteria. Through a manual search, 2 more studies were included, resulting in 10 articles evaluated at the end of this systematic review. No meta-analysis was performed in this systematic review due to the high heterogeneity between the studies, greater than 50% (I2 = 86%). Conclusion: Most studies have shown that handling composite resins with procedure gloves can cause damage to mechanical characteristics related to surface microhardness, roughness, shear bond, bond strength, compressive strength and adhesive strength of direct restorations. However, cleaning with 70% alcohol appears to partially reverse this process. On the other hand, future research is needed to demonstrate the limited confidence in the estimated effects in this investigation.
