Profilometric analysis of OptraPol®, OptraGloss®, and Sof-Lex® polishing systems on surface roughness of Endure Nano composite: An in vitro study.

AIM: The aim of this study was to evaluate the efficacy of commercially available polishing systems, 3M Sof-Lex® Diamond Polishing Spiral, Ivoclar Vivadent OptraPol®, and Ivoclar Vivadent OptraGloss®, on the surface roughness (R a) of Septodont Endure Nano composite using a profilometer. MATERIALS AND METHODS: Thirty-six disc-shaped specimens (8 mm diameter and 4 mm thickness) of Endure Nano composite were fabricated using a custom-made mold and polymerized with an LED light-curing unit. 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°C for 24 h. The samples were randomly divided into three groups (n = 12): Group I - Sof-Lex® Diamond Polishing Spiral (3M ESPE, St Paul, MN, USA), Group II - OptraGloss® (Ivoclar Vivadent AG, Schaan, Liechtenstein) Composite Kit Restoration Polisher and Group III - Optra Pól® (Ivoclar Vivadent AG, Schaan, Liechtenstein) Composite Restoration Polisher; the polishing procedure for all three polishing systems was performed according to manufacturer instructions. Surface roughness (R a) was measured at three points per specimen using a profilometer, and mean values were calculated. RESULTS: A statistically significant difference was found among the groups (P < 0.005). OptraGloss® (R a = 0.2163 µm) demonstrated the lowest surface roughness, indicating the smoothest finish, followed by OptraPol® (R a = 0.4080 µm). In contrast, 3M Sof-Lex® (R a = 0.5086 µm) exhibited the highest surface roughness. CONCLUSIONS: OptraGloss® was the most effective polishing system, producing a smoother surface compared to both OptraPol® and 3M Sof-Lex®.
