Examination of neurobehavioral and genetic information gathered from 330 of the children in the Casa Pia "Children's Amalgam Trial" study showed that genetic variances influenced susceptibility to the toxic effects of mercury. Boys with the CPOX4 gene had significantly worse performance than those with the normal gene, while girls did not show this effect. View [...]
Which delivers more mercury, dental amalgam or a tuna fish sandwich? By G. Mark Richardson, Ph.D.Risklogic Scientific Services Inc., Ottawa, ON CANADAIntroduction The debate concerning mercury (Hg) exposure from dental amalgam continues in North America (see, for example: Richardson et al., 2011; Richardson, in press). One response to this debate has been the assertion that [...]
This 2012 report confirms that “amalgam is by no means the least expensive filling material when the external costs are taken into account.” It was co-released by the IAOMT and Concorde East/West Sprl, the European Environmental Bureau, the Mercury Policy Project, the International Academy of Oral, Clean Water Action and Consumers for Dental Choice.

In January 2012, the FDA had actually prepared a "Safety Communication" that recommended reducing the use of mercury amalgam in the general population, and avoiding it in susceptible sub-populations: pregnant and nursing women children under six years of age people with allergy to mercury or other components people with neurological disease people with [...]
Completing a trifecta of refutation for the CAT studies, joining previous papers showing dose dependent effects of amalgam mercury on porphyrin metabolism and neurobehavioral performance, a new paper by David Geier et. al. shows exposure to mercury from amalgam is directly correlated with urinary mercury in children. Hum Exp Toxicol. 2012 Jan;31(1):11-7. Epub 2011 [...]
This 2011 book chapter about dental metal allergy was written by researchers in Japan. They explain, “Dental metal allergy is the general term used to describe allergic diseases caused by reactions to dental metal materials. Recently, allergic symptoms involving other dental materials, such as organic compounds, have been reported, and these allergic diseases need to [...]
Abstract: Calcium oxide, available for decades as a root canal filling material, has been little used in recent years due to its lack of radio-opacity, and an expectation that it would lead to an excess of root fractures. In this study, four general dentists submitted 79 cases of endodontically treated teeth whose roots were filled [...]
There is considerable concern among scientists and the public about the hormone-mimicking properties of many chemical components of plastics, including those found in dental composites. The commonly used Bis-GMA resin uses one of the most controversial of these, Bisphenol-A (BPA). Responsible composite manufacturers claim that there is no unreacted BPA in dental resins, and that [...]
This paper, written by engineer Robert Cartland, who testified about his own experiences with mercury toxicity at the December, 2010, FDA hearings, is a very thorough, deeply researched look at the issues under debate concerning dental amalgam.
