Abstract
Purpose To compare in vitro the surface roughness (Ra) and gloss (G) produced by three conventional and one experimental polishing kits on four resin composites Methods 24 discs were prepared (d= 12 mm, t= 4 mm) for each resin composite Filtek Supreme Plus Body/A2 (FSB), Yellow Translucent (FST), Heliomolar/A2 (HM), and EsthetX/A2 (EX) following the manufacturers' instructions They were finished with 320 grit silicon carbide paper for 80 seconds each Polishing systems Sof-Lex, Enhance-Pogo, Astropol and Experimental Discs/EXL-695, were applied following manufacturers' instructions Each specimen was ultrasonically cleaned with distilled water and dried Gloss and Ra were measured with a small area glossmeter (Novo-curve) and non-contact profilometer (Proscan 2000) following ISO 4288, respectively The results were evaluated by two-way ANOVA followed by separate one-way ANOVA and Tukey/Kramer test (P= 0 05) Results There was a significant interaction of surface roughness and gloss between the composites and polishing systems (P< 0 05) The lowest surface roughness was recorded for FST polished with the Experimental kit The highest gloss was obtained for FSB composite polished with the Experimental kit The experimental polishing system produced smoothest surfaces (P< 0 05) The Enhance-Pogo and the experimental polishing kit produced highest gloss (P< 0 05) (Am J Dent 2010,23 208-212)
