Galvanic currents between dental alloys in vitro.

摘要: The galvanic current densities between gold, amalgam and cobalt-chromium, three different classes of dental alloys, were determined in vitro artificial saliva kept at 35 degrees C. maximum density 200 microA/dm2 was obtained the conventional a type III gold alloy. Galvanic currents lesser magnitude could also be measured amalgams high copper other alloys. No measurable alloys cobalt-chromium alloy with exception casting solder commonly used combination.
