- Abstract
Aim: The aim of this study was to evaluate the surface roughness of three composites with three different polishing systems. Materials and Methods: Composite specimens were made from the Teflon mold with a standardized cavity size (6 mm diameter and 3 mm height). Group I — Filtek Z350XT (Nano clusters), group II — T-Econom plus (Microhybrid), group III — G-aenial Flo (True Nano). The samples were cured for 30 s from both sides with the matrices in place. The 60 samples were divided into 3 groups (N = 20), which accounted for 40 surfaces, (n = 20 × 2 = 40) in each groups. Each group were subdivided into four subgroups based on the type polishing material, subgroup A — Control, subgroup B — Astrobrush, subgroup C — Astropol, and subgroup D — Soflex spiral wheel. The samples of all groups except group A (control) were finished and polished according to the manufacture's instruction. Results: After polishing, the roughness (Ra) of the resin composite of all the specimens were measured using a profilometer. Soflex spiral wheel (group D) significantly had the least roughness (Ra) value as compared to the other groups. Conclusion: Among the three resin composites tested, G-aenial Flo exhibited least Ra value due to its reduced filler size and its uniform distribution.
