Objectives: This study aimed to determine the correlation between gloss and roughness in low-viscosity bulk fill resin composites. Materials and Methods: The study had an experimental, analytical, prospective, and cross-sectional design. A total of 60 composite resin blocks were evaluated and distributed into three groups of 20 units each: Group 1 - 3M Filtek Bulk Fill Flow (FBF), Group 2 - Opus Bulk Fill Flow APS (OBF), Group 3 - Opalis Flow (OF) (Reference group). Gloss and roughness were measured using a gloss meter and a contact roughness meter. Results: The FBF resin had the highest average roughness (0.35 Ra), while OF had the lowest value (0.28 Ra); in addition, OF had the highest gloss values (26.94 GU). On the other hand, there was a statistically significant high negative correlation between roughness and gloss (p < 0.01). Conclusions: There was an inverse relationship between roughness and gloss regardless of the type of resin composites evaluated.
