Abstract

Purpose: To evaluate the effects of polishing on surface roughness (Ra, um) and gloss of different shades of a surface pre-reacted glass-ionomer (S-PRG) filled flowable resin composite. Methods: Resin disks of 15 mm diameter and 2 mm thickness and final polish with 3000-grit SiC paper (#3000), super fine cut diamond point (FG) and Super-Snap mini-disk red (SNAP) were made with Beautifil Flow Plus (shades: A2, A20, Inc). The surface roughness and gloss were measured 1-week after curing. Data was analyzed with ANOVA and Fisher's PLSD with a=0.05. Results: The order of Ra differed among the composite shades. For all shades in all polishing groups, the Ra was over 0.5 um. For all shades, the gloss of the #3000 group was significantly higher than that of the FG and SNAP groups with no significant difference between the FG and SNAP groups except for the A20 shade. For A20 shade, the gloss of the SNAP group was significantly higher than that of the FG group.
