  1. DENTAL ASSISTANTS (and the rest of the dental personnel) MUST BE GLAD

    INDEED, dental assistants and the rest of the dental personnel, including dentists, must be glad because their professions (considered by the International Labour Organization as professions at risk for Chronic Mercury Poisoning), are, at last, really starting to be better studied, and, therefore, the dangers are timidly starting to be not fully hidden at the Faculties of Dentistry, Medicine, etc., or ‘underneath’ research projects, books or articles written by authors with various conflicts of interest, empty words, promises... We all know (the FDA had to recently recognised it publicly:, that also those who have in their mouths dental amalgam fillings are at risk (but this was not the aim of this article).

    Most probably, future generations will hardly understand why such dental material was still generally used in the 21st century, without at least considering the Precautionary Principle, and also knowing that, as Prof. Dr. Maths Berlin stated in the 2003 Report for the Swedish Dental Material Commission “Mercury in Dental-Filling Material--An Updated Risk Analysis in Environmental Medical Terms" — “…fully adequate and less toxic alternatives are available” (p. 25).

    All in all, our most sincere CONGRATULATIONS to the authors for conducting the research and for writing the article, and also our sincere CONGRATULATIONS to the Journal of Occupational Medicine and Toxicology for publishing the article, and, thus, allowing the readers to continue learning about the subtle (but relevant) health effects of such powerful heavy metal.
