The purpose of this study was to compare the surface roughness (RA) of conventional nanoparticulate and bulk fill composite resins, when were exposed to Vitamin C and toothpastes. 64 composite resin discs were manufactured (10mm in diameter by 2mm thick) divided into two groups, 32 of conventional nanoparticle resin and 32 of Bulk fill nanoparticle resin, 8 samples from each group were exposed for 2 min. to Vit C for 28 days, to conventional toothpaste and to a whitening toothpaste, where the discs received the tooth brushing treatment in a machine that simulated the horizontal movements of this procedure in 120 cycles per 1 minute also in 28 days, the groups control were exposed to distilled water. The RA reading was taken on a rugosimeter at the beginning and at the end of exposure to the agents. The RA results were analyzed by the Anova test (p 0.00), the Tukey test and the Student`s t-test (p 0.05). There were statistically significant differences when comparing the RA of conventional nanoparticulate composite resins and Bulk fill, when exposed to chemical and physical agents, where the group corresponding to the Bulk fill resin exposed to conventional toothpaste presents greater RA. Likewise, there were statistically significant differences when comparing the RA of conventional nanoparticulate composite resins and Bulk fill before and after exposure to Vit C and conventional and whitening toothpastes.
