Corrosion rates of dental amalgam in Ringer solutions and artificial saliva.

Corrosion currents of dental amalgams in Ringer solution, Ringer lactate solution and an artificial saliva were determined as a function of flow rate using the linear polarization technique. The obtained results show that corrosion is far more intense in Ringer solutions than in saliva. Also, flow rate dependence is evident for Ringer solutions but not for saliva in the range investigated.
