[The influence of different electrolytes on the electrochemical polarization behaviour of dental amalgams].

Abstract

The measurements of electrochemical polarization of dental amalgams was studied in 5% sodium chloride aqueous solutions, in an artificial saliva and in natural saliva with different pH-values. The non-gamma-2-amalgams have been reported to have higher corrosion resistance in comparison to gamma-2-phase containing amalgams. The results show that the electrochemical corrosion behaviour is strongly differentiated using natural saliva.
