Exposure to mercury from dental amalgams has generally been considered to occur via either erosion or evaporation directly from the surface of fillings, followed by ingestion. This study determined the relative importance of the direct migration of mercury through the tooth as an alternative exposure pathway. Most importantly the detection of Hg in areas of the tooth that once contained an active bloodstream and in calculus indicates that both exposure pathways should be considered as significant.

Heavy metals are known to induce functional alterations in kidney mitochondria, this damage plays a central role in the mercury-induced acute renal failure. In fact, mercury causes rapid and dramatic changes in the membrane's ionic permeability in such a way that a supra load of mitochondrial Ca(2+) occurs. As a consequence, the phenomenon of permeability transition takes place.

In 1810, two British ships, HMS Triumph and HMS Phipps, salvaged a large load of elemental mercury from a wrecked Spanish vessel near Cadiz, Spain. The bladders containing the mercury soon ruptured. The element spread about the ships in liquid and vapor forms. The sailors presented with neurologic compromises: tremor, paralysis, and excessive salivation as well as tooth loss, skin problems, and pulmonary complaints.

Multiple federal service dental clinics have reported that mercury is released from Kerr amalgam capsules during trituration. Users have reported mercury in the mixing chambers of their triturators and have witnessed mercury ejection during trituration. The USAF Dental Investigation Service contacted The Kerr Corporation, who confirmed mercury is released from its capsules.

Although a patient is legally entitled to information regarding the risks and benefits of proposed and alternative treatments, the ADA and state dental boards have vehemently resisted informing patients about the risks of mercury amalgams and have been disciplining dentists who advocate against mercury amalgams.

Our immune system is a complex network of special cells and organs that defends the body from germs and other foreign invaders. At the core of the immune system is the ability to tell the difference between self and nonself: A flaw can make the body unable to tell the difference between self and nonself. When this happens, the body makes autoantibodies that attack normal cells by mistake. At the same time special cells called regulatory T cells fail to do their job of keeping the immune system in line. The result is a misguided attack on your own body. 

This study summarizes the clinical features of mercury poisoning diagnosed by blood and urine tests for improving the diagnosis and treatment of the disease. Because of its diverse clinical symptoms, the mercury poisoning was easy to misdiagnosis and missed diagnosis; therefore the awareness of the disease should be further enhanced. Leaving from the poisoning environment timely and giving appropriate treatment with DMPS will lead to a satisfactory prognosis.

In this study, people with amalgam suffered more symptoms such as depression, anger, hostility, psychotism, and were more obsessive-compulsive than the patients with such fillings removed. These data suggested that the poorer mental health status exhibited by multiple sclerosis subjects with dental amalgam fillings may be associated with mercury toxicity from the amalgam.

Women with "siver" amalgam mercury fillings had a higher incidence of depression, excessive anger, and anxiety. This study suggests that amalgam mercury fillings may be an etiological factor in depression, excessive anger, and anxiety because mercury can produce such symptoms perhaps by affecting the neurotransmitters in the brain.

In 1997 The Environmental Protection Agency compiled the Mercury Study Report to Congress. This document covers the human health effects of mercury and mercury compounds. Upon reading the symptoms of mercury vapor-induced neurotoxicity and the toxicokinetics, it is apparent that mercury has great potential to mimmic symptoms of dementia and Alzheimer's disease.

The Agency for Healthcare Research and Quality under The Department of Health and Human Services used our tax dollars to have the Duke University, Evidence-based Practice Center (EPC) conduct research for a report "Preventing Alzheimer's Disease and Cognitive Decline". The group found only one study fitting their criteria linking mercury to Alzheimer's disease, although there is over 20 years worth of publish studies showing a relationship between mercury and Alzheimer's disease.
