Abstract:
The aim of this study was to compare the roughness of the surface of one nanofill (Filtek Supreme XT 3M Espe, St. Paul, USA) and one silorane (Filtek Silorane, 3M Espe, St. Paul, USA) composite after polishing. Five specimens of each composite were polymerized under a polyester strip for 40 seconds. After curing four probes were polished with different Sof-Lex discs and one probe with Pogo for ten seconds. For the surface appointment a contact stylus profilometer was used. The profilometer made ten tracings for each sample at different locations. There was a significant difference in roughness between both composites. The Ra (average surface roughness) results for the silorane composite were almost always significantly higher than for the nanofill composite (T-test). For both composites Sof-Lex fine and superfine discs produced smoother final surfaces than Pogo. The nanofill composite used showed the smoothest surfaces after the polishing and finishing procedures.
