Effect of Chloride and Fluoride on the Rate of Corrosion of dental amalgam alloys

摘要

AbstractThe anodic behaviour of massive and dental amalgam alloys in artificial saliva containing different concentrations of Cl−or F−ions has been studied. Quantitative relations could be established between concentrations of these ions and the height of the peaks corresponding to anodic oxidation of Sn or Ag. Contrary to f−, Cl−ions from Ag complexes via AgCl which excess cl−ions. The massive alloy is stable below 0.15 V. Calcium fluoride can be safely admixed with dental amalgam alloy without enhancing its
