A comparative study of the electrochemical corrosion behaviour of dental amalgams

The electrochemical corrosion behaviour of sixteen currently marketed amalgams for dental fillings was studiedin vitro under experimental conditions closely resembling those of clinical application. Depending upon the type of amalgam and the treatment of the filling the electrochemical corrosion currents varied over several orders of magnitude; their change as a function of time was also very different. Suggestions are made for a stability rating of the products based on the results obtained.
