Abstract

The anodic behaviour of massive and dental amalgam alloys in artificial saliva containing different concentrations of Cl^βˆ’^ or F^βˆ’^ 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^βˆ’^, Cl^βˆ’^ ions from Ag complexes via AgCl which excess cl^βˆ’^ions. The massive alloy is stable below 0.15 V. Calcium fluoride can be safely admixed with dental amalgam alloy without enhancing its corrosion.

Previous studies have shown preferential corrosion of the q'(Cu-Sn) phase in highcopper dental amalgam both in vifro and in vivo, while samples of pure 7' have shown high corrosion resistance. To clarify this contradiction, samples of pure q' crystals mixed with other phases were prepared and tested
