초록
The corrosion of silver amalgam is regarded as one of major causes in the failures of dental amalgam restorations. To evaluate the corrosion resistance of dental amalgam alloys, electrochemical tests such as potential and polarization measurement were used widely. But these commonly used methods have not provided the sufficient informations on relative resistance of amalgam to corrosion. In this experiment, the corrosion currents were measured using electronic potentiostat to compare some commercial dental amalgam alloys. All alloys were triturated in a amalgamator and condensed into a mold described in A.D.A. Specification No. 1 to produce cylinder form specimens of 4mm diameter by 5mm long. After specimen kept for 1 week at
