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.
在储存介质[乳酸溶液（pH 4.0）]中进行热循环后，将三种玻璃离子水门汀的表面质地变化与上釉和抛光的水门汀表面进行了比较。在实验室中，针对表面粗糙度、颜色变化、光泽度、硬度、牙刷磨损以及扫描电子显微镜（SEM）观察对这些变化进行了测量。在乳酸溶液中进行热循环后，上釉的水门汀表面未受影响。
