A systematic review and network meta-analysis was performed to provide evidence for the best polishing protocol for different types of resin composites to minimize surface roughness. A search was performed in PubMed, Scopus, Web of Science, LILACS, BBO, EMBASE, and Cochrane Library on July 2, 2019 (updated in December, 2020). In vitro studies that included at least two systems for polishing resin composites and analyzed surface roughness were included. The risk of bias was evaluated. A random-effects Bayesian-mixed treatment comparison model was used to compare surface roughness in resin composites with the different types of polishers. Surface under the cumulative ranking curve (SUCRA) analysis was performed to rank the probability for the best polishing system. After removal of duplicates, title and abstract screening yielded 34 studies. Network meta-analysis was not possible for hybrid and microhybrid composites. SUCRA analysis showed that abrasive paper discs allowed greater surface smoothness for nanohybrid and nanofill composites to a probability of between 83% and 91.6%. Silicon carbide brush had a 78.2% probability of being the best system for microfill composites. The use of abrasive paper disc polishers showed a favorable result in nanofill and nanohybrid resin composites. Silicon carbide brush has a greater chance of promoting a smoother surface for microfill resin composites.

Introdução: A resina composta é um dos materiais restauradores mais pesquisados na Odontologia, visando melhorias nas suas propriedades e aperfeiçoamento da técnica. Este trabalho tem o objetivo de avaliar a rugosidade superficial de duas resinas compostas, microhíbrida e nanoparticulada, após a polimerização adicional com micro-ondas. Materiais e métodos: Para cada resina composta, foram confeccionados 24 corpos de prova, medindo 0,8cm de diâmetro interno por 0,2cm de espessura, dos quais, 12 receberam polimerização adicional com micro-ondas e 12 apenas a polimerização com luz azul visível. Foram estabelecidos quatro grupos: G1- resina microhíbrida submetida polimerização convencional, G2 - resina nanoparticulada submetida a polimerização convencional, G3- resina microhíbrida exposta a polimerização adicional em forno de micro-ondas caseiro e G4- nanoparticulada exposta a polimerização adicional em forno de micro-ondas caseiro. Os corpos de prova foram lixados em politriz com o intuito de uniformizar as superfícies, seguidos pela leitura no rugosímetro digital Mitutoyo SJ 301. O teste não paramétrico Exato de Mann-Whitney (significância de 5%) foi realizado utilizando a média aritmética (Ra, µm). Conclusão: Não houve significância estatística entre os tipos de polimerização e nem entre as diferentes resinas compostas estudas.
