Effect of finishing procedures on surface textures of some resin restoratives. A comparison between new and old types of composite resins.
Evaluation were made of the effect of different finishing procedures on the surface textures of a conventional composite material, two newly introduced microfiller composite resins, a visible light polymerized resin, and a glass ionomer cement. The two micro-filler composite materials appeared to be superior in finishability compared with those materials loaded with larger filler particles. The use of fine grit devices particularly resulted in smooth surfaces. This is in contrast to the other materials which always showed rough surface textures with protruding filler particles. The use of a polishing paste improved the surface finish of the micro-filler materials in contrast to the materials with larger filler particles.
