Objectives: This in vitro study aimed to evaluate the effect of different polishing methods on the surface roughness of four resin-based composites with different types.
Methods: Four different types of resin-based composites (RBC) from the same manufacturer were used: a nano RBC (Dr. Müller Kaiser, Remar Technik GmbH, Lübbecke, Germany), a micro-hybrid RBC (Dr. Müller Kaiser), a flowable RBC (Dr. Müller Kaiser), and a bulk-fill RBC (Dr. Müller Kaiser). The 45 cylindrical specimens (4mm in diameter, 2mm in thickness) were prepared for each RBC using a Teflon mold placed up to a strip and after packing another strip was placed on the top surface of materials and materials were cured at standard power (1000 mW/cm2) using a light-curing unit (Valo, Ultradent, South Jordan, UT, USA). Then specimens were divided into 3 subgroups according to polishing procedures; G1 (Control, no polishing), G2 (Composoft, Eve, Ernst Vetter GmbH, Keltern, Germany), and G3 (Super Snap, Shofu Inc., Kyoto, Japan). Initial surface roughness (Ra) measurements were recorded using a contact profilometer and surface roughness measurements were repeated after polishing. All specimens were stored in distilled water, and roughness measurements were conducted at three time intervals: 24h, 1w, and 1m. Statistical analyses were performed using one-way analysis of variance (ANOVA) and Tukey (p ≤ 0.05).
Results: All composite materials maintained their surface roughness values over time and exhibited long-term surface smoothness. No statistically significant differences were observed among the polishing protocols applied.
Conclusions: All composite materials maintained their surface roughness values over time and exhibited long-term surface smoothness. No statistically significant differences were observed among the polishing protocols applied.
