The surface and solubility of some glass ionomer cements have been assessed after exposure to four acids (acetic, formic, lactic and propionic), that are usually present in the bacterial plaque. Therefore, we prepared 80 samples--20 for earl of 4 commercial products; after 7 days and, then after 30 other days, the samples were examined by microscope and weighed. Finally, those showing the most significant modifications were photographed.
在暴露于通常存在于牙菌斑中的四种酸（乙酸、甲酸、乳酸和丙酸）之后，对一些玻璃离子水门汀的表面和溶解性进行了评估。因此，我们制备了80个样本——4种市售产品各20个；7天后，然后再过30天，通过显微镜对样本进行检查并称重。最后，对那些显示出最显著变化的样本进行拍照。
