The study compared surface roughness and hardness of tooth‑colored restoratives polished with Enhance, white stones, and Super‑snap systems, using profilometry and microhardness testing, with a Mylar‑strip cured control. Polishing system effects on surface roughness and hardness were found to be material dependent, driven by differences in filler–matrix hardness, filler content, particle size, and the system’s abrasive action.
The surface characteristics of different tooth-colored restoratives polished with the Enhance system, white stones, and the Super-snap system were evaluated using profilometry and microhardness testing. Surface characteristics of materials cured against a Mylar Uni-strip were used as a control. The results of this study show that the surface characteristics (roughness and hardness) following polishing with different systems are material dependent. The result may be attributed to the discrepancy between filler and matrix hardness of the restorative. Filler content, particle size, and the ability of the polishing system to abrade the filler may also contribute to the observed change in surface characteristics.
