"Doubt is our product," a cigarette executive once observed, "since it is the best means of competing with the 'body of fact' that exists in the minds of the general public. It is also the means of establishing a controversy." This book gives great insight into how trade organizations like the American Dental Association can use junk science to manufacture doubt and controversy.

Researchers Dr. Mark and David Geier show how the data from the "children's amalgam trial" studies, originally published in the Journal of the American Medical Association, and purported to prove the safety of mercury amalgam, actually show a dose-dependent toxicity in a key metabolic system.

Boyd Haley PhD explains why the apolipoprotein-4 (APOE-4) genotype represents a genetic susceptibility to mercury toxicity as a pathogenetic factor and a moderator of Alzheimer's Disease.

The functional integrity of endothelium is crucial for the maintenance of blood flow and antithrombotic capacity. Vascular endothelium is highly sensitive to oxidative stress, and this stress is the main cause of the endothelial dysfunction observed in cardiovascular diseases. Chronic exposure to low concentrations of mercury promotes endothelial dysfunction. These findings offer further evidence that mercury, even at low concentrations, is an environmental risk factor for cardiovascular disease.

Mercury has been linked to Alzheimer's disease by a number of different studies that have accumulated over the last two decades. Watch and listen to published scientists talk about how mercury can cause many of the hallmarks of Alzheimer's disease. This article was taken from the IAOMT's Petition For Reconsideration, which prompted the FDA to re-evaluate their 2009 ruling that amalgam was safe for everyone.

Boyd Haley P.h.D. discusses the findings of his published studies (and others), which showed that mercury and only mercury can cause the major biochemical hallmarks of Alzheimer's disease and how the NIH stopped his funding after he published those findings.

OSHA has noted the American Dental Trade Association's (ADTA) position that Material Safety Data Sheets (MSDSs) fall within FDA's definition of labeling. As we have discussed in earlier meetings, this is unfounded.

Mercury free dentists have been known to polish and remove  "silver" amalgam fillings thereby exposing their patients and staff members to thousands of micrograms of mercury vapor and particulate matter. "Mercury Safe" dentists take every precaution to protect the patient, staff and environment from harmful mercury vapors and mercury contaminated particulate matter.

With public concerns related to mercury becoming more common, it is essential to have a partner that you can trust with your mercury compliance needs. Mercury Instruments USA has made it affordable for you to easily prove and defend that your dental practice is compliant with the OSHA & NIOSH (REL) recommended exposure limits for mercury vapor in the workplace.

The Environmental Protection Agency (EPA) has mandated that dentists install amalgam separators, which captures 99.5% of waste amalgam containing mercury.

We investigated whether circulating levels of metals related differently to coronary risk in men and women. Hg, Pb and Zn levels were significantly higher in men. The most striking finding is that Hg levels were positively related to LDL and inversely to HDL, suggesting an important role of Hg in determining an atherogenic lipid profile.

Before becoming FDA commissioner, Margaret Hamburg was on the board of Henry Shein, one of the largest distributors of dental amlgam filling materials. When Senator Enzi, as part of the confirmation process, asked Dr. Hamburg written questions about the upcoming amalgam rulemaking, she failed to disqualify herself or disclose her conflict even though she had been briefed on the issue enough that the conflict should have been apparent. She refuses to answer questions regarding her involvement in the decision making process and notified us of her...

This study estimated Hg body burden from dental amalgam fillings in 182 children. The detrimental neurobehavioral and/or nephrotoxic effects of such an increased Hg on children should be a cause of concern, and further investigation is warranted. Our results are alarming and indicate an urgent need for biomonitoring and assessment of exposure. Changes in dental practices involving amalgam, especially for children, are highly recommended in order to avoid unnecessary exposure to Hg. 

People with amalgam fillings have higher concentrations of mercury in blood, plasma, urine & body organs than people without amalgam fillings. Long-lasting reductions in intra-oral and general health complaints in the treatment group were significantly different from the reference group. In the treatment group, intra-oral and general health complaints were significantly reduced 3 years after replacement of amalgam fillings.

Deregulation of gap junctional intercellular communication (GJIC) is a common phenotype of cancer cells and supports its involvement in the carcinogenesis process. In this study we investigated the effect of Hg(II) (HgCl2) on GJIC in cultured human keratinocytes. It is shown that sub-cytotoxic concentration of HgCl2 as low as 10 nM causes inhibition of the GJIC.

There is increasing concern that environmental chemicals have a direct effect on fertility. Heavy metals such as mercury have been shown to affect various organ systems in humans including nervous system and skin, however they could also act as endocrine disrupting chemicals adversely affecting fertility. Our results suggest that mercury may act as an endocrine disruptor with a deleterious effect on the ovarian response to gonadotrophin therapy

Exposure to toxic mercury (Hg) is a growing health hazard throughout the world today. Recent studies show that mercury exposure may occur in the environment, and increasingly in occupational and domestic settings. Children are particularly vulnerable to Hg intoxication, which may lead to impairment of the developing central nervous system, as well as pulmonary and nephrotic damage. Several sources of toxic Hg exposure in children have been reported in biomedical literature such as that from dental mercury amalgam fillings.
