local.description.resumoObjective. This study evaluated the effect of immediate or delayed finishing/polishing using different systems on the surface roughness, hardness, and microleakage of a silorane-based composite. Material and Methods. Specimens were made with silorane based composite (Filtek P90, 3M ESPE) and assigned to the treatments: control (light-cured); aluminum oxide discs (Sof-Lex, 3M ESPE); diamond-impregnated silicone tips (Astropol, Ivoclar Vivadent); aluminum oxide-impregnated silicone tips (Enhance, Dentsply). Half of the specimens were finished/polished immediately and the rest after 7 days. Surface roughness (Ra, 𝜇m; 𝑛 = 20) and Vickers microhardness (50 g; 45 s; 𝑛 = 10) were measured. Cavities were prepared in bovine incisors and filled with Filtek P90. The fillings received immediate or delayed finishing/polishing (𝑛 = 10) and were subjected to dye penetration test (0.5% basic fuchsin, 24 h). Data were analyzed by ANOVA and Scheffe, Kruskal-Wallis, and Mann-Whitney tests (𝑝 < 0.05). Results. The finishing/polishing system significantly influenced roughness and microhardness (𝑝 < 0.0001). For enamel, microleakage was not affected by the finishing/polishing system (𝑝 = 0.309). For dentin, Sof-Lex discs and Astropol points promoted greater microleakage than Enhance points (𝑝 = 0.033). Conclusion. Considering roughness, microhardness, and microleakage together, immediate finishing/polishing of a silorane-based composite using aluminum oxide discs may be recommended
