Among a number of conclusions, the author notes, "-Compared to known toxic values, mercury from dental amalgam fillings presents a substantial contribution to the body mercury load. - Amalgam removal results in alleviation of symptoms, known to occur upon chronic exposure to mercury."
Abstract / Excerpt:
“Corrosion attacks on twenty-two dental amalgam restorations after in vivo service have been studied by Scanning Electron Microscopy together with the Energy Dispersive X-Ray Technique, and by optical microscopy. From the measured depth and type of corrosion attack, estimates of released mercury amounts are made. The amalgam fillings have been obtained from members of a group of 250 individuals, who suspected their health troubles potentially to be chronic mercury poisoning from amalgam and were to have all amalgam fillings removed. Three typical patient cases are presented. Model calculations of released mercury, based on previously published measurements of corrosion currents with and without abrasion are also given. The investigations show, that the long-term release of mercury from a few amalgam fillings will often reach or exceed the recommended limits for daily intake of mercury. Hence, mercury from corroding amalgam fillings represents a potential health hazard. Danger of galvanic contact between amalgam and gold restorations is particularly emphasized.”
