Abstract
Seven commercial composite filling materials were studied as regards 1) differences in their ability to take a smooth polish as measured by an electronic roughness gauge and 2) their relative loss in smoothness due to toothbrushing. A series of test formulations indicated that polishability and ability to retain a good polish are interrelated and are functions of filler particle size and filler hardness. Optimization in the filler particles from the point of view of polishability also results in improved wear resistance to toothbrushing.Keywords
