Corrosion of amalgams in oral cavity

Abstract EN

This paper is a study of the effect of natural saliva (oral cavity) and a fluoride mouthwash on dental amalgams.

Two types electrodes were made the first was of a high copper amalgam while the second was made from a low copper amalgam.

They were immersed in two types of electrolytes for twelve hours and the whole galvanic cell was connected to a computer via a potentiosat.

Their corrosion currents, corrosion voltage and corrosion resistance was recorded and compared to find which medium that is usually has the most severe effect on the amalgams corrosion.
