Dental amalgam controversy from the WHO concluded that dental amalgam contributes significantly to mercury body burden in humans with amalgam fillings and that dental amalgam is the most common form of exposure to elemental mercury in the general population, constituting a potentially significant source of exposure to elemental mercury. Estimates of daily intake from amalgam restorations range from 1 to 12.5 μg/day, with the majority of dental amalgam holders being exposed to less than 5 μg mercury/day. They also note that this will continue to decline as the number of amalgam restorations is declining. As public pressure demands more research on amalgam safety,
Dental amalgam controversy ADA asserts the best scientific evidence supports the safety of dental amalgam. Clinical studies have not established an occasional connection between dental amalgam and adverse health effects in the general population. In 2002, Dr. Maths Berlin of The Dental Material Commission published an overview and assessment of the scientific literature published between November 1997 – 2002 for the Swedish Government on amalgam and its possible environmental and health risks. A final report was submitted to the Swedish Government in 2003 and included his report as an annex to the full report. In the final report from 2003, Berlin states that
