CORROSION OF AMALGAMS IN ORAL CAVITY
Main Article Content
Abstract
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.
