title: [Comparison of two powder-stream systems for tooth polishing].
abstract: The effect of two airpolishing systems on the surface roughness of polished ceramic test pieces was compared and evaluated using standardized procedures. Test pieces resembling enamel in hardness were treated with these air-polishing systems. Using a Perthometer surface roughness was found to increase significantly. Thus the possible effects of airpolishing systems on the enamel surface should be considered. Efficiency of extrinsic stain removal was studied by SEM and documented. Photographic techniques provided information on the homogeneity of the sodium bicarbonate spray.
