Abstract
The present studies are concerned with the soluble elements, properties of set cement surface and its elemental analysis of dental cements in distilled water.Zinc phosphate cement is soaked in distilled water for a day, the soluble elements are Zn 4.2μg/cm2, and Mg and Ca, respectively 2.9 and 0.4μg/cm2.Again, in the case of 7 days soak, the author presumes that zinc phosphate is separated as crystals, approximately 10μm, on the surface, judging from the EPMA's face analysis.
The amount of solubility of Zn of carboxylate cement, both in a day and 7 days soak case, is comparatively small, but Mg, in both cases, shows large values, resp ectively 2.9 and 26.2μg/cm2.
The amount of solubility of silicate cement is in the case of a day soak, Na shows a large value, 247.1μg/cm2, which reaches 340.2μg/cm2 when soaked for 7 days. Again, Si and Al, in the case of a day soak, respectively show 33.0 and 36.1μg/cm2, which increase in the case of 7 days soak.
