Sažetak
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, 3MEspe, 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.
