Abstract:
Objective: The galvanic corrosion behavior of dental amalgam coupled to three types of dental alloys in common use(pure Ti?Ni-Cr alloy and Co-Cr alloy),was investigated in artificial saliva.Methods: An electrochemical method was used in the measurement of corrosion potential(Ecorr)?polarization resistance(Rp) and corrosion current density(Icorr) of four types of alloys,and current density of three galvanic couples.These electrochemical parameters were analyzed statistically.Results: The corrosion potential,polarization resistance and corrosion current density,respectively,were statistically different among the different alloys(P
