Due to the overvaluation of aesthetics, there has been an intense demand by the patients for restorative treatments that reproduce the teeth in the most faithful way possible, as well as the occurrence of significant advances in the development and improvement of aesthetic restorative materials and systems of finishing and polishing to supply such demand. Among the several factors, the surface smoothness of a restoration constitutes one of the determinants of aesthetic success, since rough surfaces contribute to the deposition of debris, pigments and bacteria, in addition to lower gloss, and the surface reflection restoration related to different finishing and polishing methods. This systematic review aims to evaluate the correct finishing and polishing protocol that obtains an ideal surface smoothness. It will be reviewed laboratory studies, randomized clinical trials, controlled clinical studies, and observational studies. Search strategies will be determined by setting search keys related to the subject in the following databases: Pubmed (MedLine), Scopus, Web of Science, LILACS, The Cochrane Library and Brazilian Library in Dentistry (BBO). Two examiners will perform the analysis, selection of studies and data collection. In the initial phase, will be directed the choice according to the title and summary of the works and evaluated according to the risk of bias. The selected studies will form a narrative synthesis of the data obtained and after the extraction of these data; will be performed the heterogeneity of the data, and posterior meta-analysis.
