| Abstract: | The method of neutron activation and gamma-ray spectrometry was used for studying galvanic corrosion of dental amalgam. The behaviour of galvanic couples of zinc containing and zinc free amalgam with dissimilar electrodes from other restorative material was investigated in various electrolytic media, in absence and presence of oxygen. Severe corrosion of amalgam takes place when coupled with gold electrodes. |
