[A weight and surface analysis of glass ionomer cements in the presence of acid solutions].
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.
