Abstract:
The surface texture changes of three kinds of glass-ionomer cements were compared with glazed and polished cement surfaces after thermal cycling in a storage media [lactic acid solution (pH 4.0)]. The changes were measured with regard to the surface roughness, colour-change, gloss, hardness, toothbrush wear, and SEM (scanning electron microscope) observation in the laboratory. The glazed cement surface was not affected after thermal cycling in the lactic acid solution.
