Objective.
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.
