Wenn Amalgam schädlich ist, dann müßten sich beim zahnärztlichem Praxispersonal Schäden nachweisen lassen.

Die Existenz solcher Schäden wurde strikt geleugnet. Es gibt aber Studien, die ein anderes Bild zeigen. Eine davon ist nicht nur als abstract, sondern auch als Volltext im WWW. Den abstract aus der U.S. National Library of Medicine zitiere ich nun. Den Volltext finden Sie bei dem Link, der am Ende des abstracts angegeben ist:

Potential toxicity from exposure to mercury vapor (Hg(o)) from dental amalgam fillings is the subject of current public health debate in many countries. We evaluated potential central nervous system (CNS) toxicity associated with handling Hg-containing amalgam materials among dental personnel with very low levels of Hg(o) exposure (i.e., urinary Hg <4 microg/l), applying a neurobehavioral test battery to evaluate CNS functions in relation to both recent exposure and Hg body burden. New distinctions between subtle preclinical effects on symptoms, mood, motor function, and cognition were found associated with Hg body burden as compared with those associated with recent exposure. The pattern of results, comparable to findings previously reported among subjects with urinary Hg >50 microg/l, presents convincing new evidence of adverse behavioral effects associated with low Hg(o) exposures within the range of that received by the general population.
