on the Rate of Corrosion of Dental Amalgams

First Published November 1, 1971 Research Article


Corrosion studies have been carried out on dental amalgams with and without additions of stannous fluoride to the alloy before trituration. Corrosion studies also were carried out with additions of sodium fluoride and stannous fluoride to test solutions. When added to the amalgam, stannous fluoride caused a decided increase in its deterioration. Addition of stannous fluoride to the test solution had no effect on corrosion, whereas addition of sodium fluoride to the solution decidedly increased the corrosion rate.
