The choice of the best finishing/polishing methods for composite resin restorations is critical to the choice of excellence results related to longer clinical longevity. The objective of the study was to evaluate the influence of finishing and polishing systems on the surface roughness of a Nanoparticulate and Bulk-fill resin. For the research, 40 sample disks were prepared for each composite single-increment (BF) (Bulk Fill 3M), both 2 mm thick and 10 mm in diameter (FZ) (Filtek Z350, 3M). The specimens were randomly divided into 4 groups with 10 samples each, according to the different materials to which they were subjected to the finishing and polishing protocols control [C]- diamond tip (FG 4137F FAVA); [EN] polishing discs (Enhance, Dentsply); [SL] Abrasive discs (Sof-Lex Pop-on, 3M) and [PD] felt disc + Polishing paste (Diamond Excel, FGM). A surface roughness (Ra) was verified with a roughness meter in three different data volumes and calculated as arithmetic means. Data were statistically treated by one way ANOVA followed by test t and student t test. Regardless of the data tested, evidence of the systemic controlling against different systems for polishing control with control (p <0.05). PD presented statistically greater roughness to the EN and SL (p <0.001), these in turn obtained similar performance and presented the lowest values of roughness for both composites (p> 0.05). The different finishing / polishing methods influenced the surface roughness of both composites, observing for Sof-lex and Enhance lower Ra values. (AU)
