All specimens were sequentially finished under running water with 400-, 600-, and 1000-grit silicon carbide abrasive papers to standardize surface texture and then stored in saline at 37\u00b0C for 24 h. The samples were randomly divided into three groups (\n n<\/jats:italic>\n = 12): Group I \u2013 Sof-Lex\n \u00ae<\/jats:sup>\n Diamond Polishing Spiral (3M ESPE, St Paul, MN, USA), Group II \u2013 OptraGloss\n \u00ae<\/jats:sup>\n (Ivoclar Vivadent AG, Schaan, Liechtenstein) Composite Kit Restoration Polisher and Group III \u2013 Optra P\u00f3l\n \u00ae<\/jats:sup>\n (Ivoclar Vivadent AG, Schaan, Liechtenstein) Composite Restoration Polisher; the polishing procedure for all three polishing systems was performed according to manufacturer instructions. Surface roughness (\n R<\/jats:italic>\n a<\/jats:sub>\n ) was measured at three points per specimen using a profilometer, and mean values were calculated.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n A statistically significant difference was found among the groups (\n P<\/jats:italic>\n < 0.005). OptraGloss\n \u00ae<\/jats:sup>\n (\n R<\/jats:italic>\n a<\/jats:sub>\n = 0.2163 \u00b5m) demonstrated the lowest surface roughness, indicating the smoothest finish, followed by OptraPol\n \u00ae<\/jats:sup>\n (\n R<\/jats:italic>\n a<\/jats:sub>\n = 0.4080 \u00b5m). In contrast, 3M Sof-Lex\n \u00ae<\/jats:sup>\n (\n R<\/jats:italic>\n a<\/jats:sub>\n = 0.5086 \u00b5m) exhibited the highest surface roughness.\n <\/jats:p>\n <\/jats:sec>\n \n
