Evaluation of surface roughness of three different composite resins with three different polishing systems

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.

Comparative evaluation of effect of different polishing systems on surface roughness of composite resin: An in vitro study

“…After polishing of restoration, filler particle are left protruding while resin matrix remains shorter. [ 3 ] This results into surface roughness. This can be reduced with use of an effective polishing system.…”

“…[ 1 2 ] Improper surface finishing of restorations can result in plaque accumulation, gingival inflammation, periodontal problems, demineralization of enamel, staining, caries, and poor esthetic. [ 1 3 4 ] Even 0.3 μm of surface changes can be easily detected from the tongue tip. [ 1 ] Hence, smooth surface finish of dental restoration is most important.…”

“…Lastly, the 3M Soflex system (3 M ESPE, St. Paul, MN, USA) which includes finishing discs and the most recently introduced Soflex spiral wheels are also being used by orthodontists. The discs are made up of aluminum oxide particles from coarse to superfine (50 to 80 μ), whereas the spiral wheels are made up of diamond particles impregnated in thermoplastic elastomer [10, 11].…”
