[Amalgam--"etiology" of psychiatric disorders?].

In a liability lawsuit an expertise had to answer the question whether a mania in the course of an affective psychosis could have been caused by chronic mercury intoxication resulting from dental amalgam fillings. On the basis of current psychiatric and toxicological knowledge, such an association can be disproved. Mercury intake from amalgam fillings does not lead to toxic concentrations in organs or body fluids. Therefore physicians and dentists should avoid alarming patients and thus causing iatrogenic harm.
