Surface roughness of microfilled composites.
Average surface roughness values, profile tracings, and surface microstructures of three microfilled composites and a conventional composite were studied with respect to final finishing procedures. Surfaces cured against Mylar matrix strips were the smoothest and were similar for all composites. White stones produced the roughest surfaces for Isopast, Silar, and Superfil. Silicon carbide disks and aluminum oxide disks produced smoother surfaces. The finished surfaces of the microfilled composites were smoother than the corresponding surfaces of Concise for each finishing instrumentation evaluated.
