The effect of occupational exposure to mercury vapour on the fertility of female dental assistants Exposure to mercury vapour or inorganic mercury compounds can impair fertility in laboratory animals. To study the effects of mercury vapour on fertility in women, eligibility questionnaires were sent to 7000 registered dental assistants. Detailed information was collected on mercury handling practices and the number of menstrual cycles without contraception it had taken them to become pregnant.
Karen Palmer, Mercury Poisoned Dental Assistant- 2006 FDA Testimony As a dental assistant I handled mercury every day for years until 2004 when I was diagnosed with heavy metal mercury poisoning. I am disabled and can no longer work due to the neurological damage from occupational exposure to mercury.
Karen Burns, Mercury Poisoned Dental Assistant - 2010 FDA Testimony Today I want to speak to the panel and urge them to help the FDA do their job. I testified at the FDA hearing in 2006, I watched the FDA panel vote 13-7, based on the fact that they could not prove amalgam was safe. I don't know what happened after that. It seems like they didn't do anything except make claims of safety without proof.

Dr. Janet Stopka D.D.S. shares her mercury toxicity story with FDA My name is Dr. Janet Stopka D.D.S.  I am a practicing dentist from Chicago.  I have not used mercury as a restorative material in 14 years and my patients are given informed consent.  No one has ever asked me to place mercury in their mouth and they understand immediately its toxic. But many of them don’t know they have it in their mouth!
Dental Amalgam Material Safety Data Sheets (MSDS) Overview The purpose of the MSDS is to protect workers by supplying them with the most crucial facts about the hazardous material at their jobsite, such as the physical properties of the material, proper storage and handling techniques, known health risks and essential emergency procedures.
IAOMT - Safe Removal of Mercury Amalgam Fillings - Video Dentists remove amalgam fillings every day, with no regard for the possible mercury exposure that can result from grinding them out.  The International Academy of Oral Medicine and Toxicology has established a mercury safe protocol that protects both staff and patients during amalgam removal.
Diane Meyer DDS Recovers from her debilitating health problems due to mercury toxicity In search of answers about her debilitating health problems, Diane Meyer, D.D.S., B.S., went from doctor to doctor and was told “It’s your hormones honey,”. Until she attended a seminar and learned of her constant exposure to mercury.
OSHA requires employers to provide a workplace free of serious recognized hazards and in compliance with OSHA Standards You have the right to a safe workplace. OSHA requires employers to provide a workplace that is free of serious recognized hazards and in compliance with OSHA Standards. David Kennedy shares stories of occupational exposure to mercury in the dental workplace. 
NIOSH - Criteria for a Recommended Standard Occupational Exposure to Inorganic Mercury The Occupational Safety and Health Act of 1970 created The National Institute for Occupational Safety and Health (NIOSH). NIOSH is an agency established to help assure safe and healthful working conditions for working men and women by providing research, information, education, and training in the field of occupational safety and health.
The Difference Between Mercury-Free and Mercury-Safe Dentistry 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.
Mercury leaking from Kerr amalgam capsules during trituration 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.
Mercury toxicity in the dental office: a neglected problem No longer can the dental profession ignore the problem of mercury contamination in the dental office. It is the moral responsibility that the dentist protect himself and his employees from any source that may be injurious to either his own physical well being or that of auxiliary personnel. It is also a legal responsibility under the enactment of the Occupational Safety and Health Act of 1970.

OSHA rebukes the American Dental Trade Association and reiterates encapsulated amalgam is a hazard that requires an MSDS 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.
Chronic neurobehavioural effects of elemental mercury in dentists A significant increase in aggressive mood measured by the profile of mood states was found between exposed and control groups. This increase in aggressive mood seemed to be related to dose, suggesting possible effects of exposure to mercury vapour on personality. 
Symptoms of Intoxication in Dentists Associated with Exposure to Low Levels of Mercury The present study examined the effects of occupational exposure of a group of dentists to low levels of mercury. Analysis of the data revealed that neuropsychological, muscular, respiratory, cardiovascular and dermal symptoms were more prevalent in dentists. Our findings indicate that occupational exposure of dentists to mercury, even at low levels, is associated with a significant increase in the prevalence of symptoms of intoxication.
Systemic mercury levels caused by inhaling mist during high-speed amalgam grinding This experiment has shown the following facts about the exposure of rats to an amalgam dust created by a high speed handpiece: 1.) The dust is almost immediately absorbed into the blood stream as shown by immediate increases detected by measuring the blood mercury content. 2. The heart receives extremely high levels of mercury within minutes after exposure. Eighty one times higher than the control level.
IAOMT Info-graphic - Occupational exposure to dental mercury The International Academy of Oral Medicine and Toxicology has released an info-graphic, Occupational Exposure to Dental Mercury,  that outlines the many ways in which occupational exposure to dental mercury occurs.

FDAThis is a complete copy of the IAOMT's addendum to their Petition for Reconsideration submitted by Jim Love, et al in March of 2013. The addendum to the petition added new proof of the damaging effect of mercury in amalgams and asked that mercury in dental materials either be banned or reclassified as an FDA Class III device thus restricting its use and increasing regulations when using this product.

icc-03To the Honorable Prosecutor Ocampo. We are requesting you authorize an investigation by the International Criminal Court (ICC) into a crime against humanity under Article 7 of the Rome Statute directed at those responsible for the design, funding, execution, analysis, and publication of an unethical scientific experiment conducted on hundreds of children.  The experiment exposed the children to significant amounts of mercury, a deadly poison, in order to justify the use of dental amalgam fillings.

casa-pia1Researchers 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.

iaomtMercury 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.

margaret-hamburg-02Before 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 recusal from the rule just 4 days prior to it being finalized in 2009.

ms-04Multiple Sclerosis (“MS”) was first commonly identified in the 19th century during the time in which mercury/silver fillings came into common use. There is toxicological evidence that mercury poisoning victims and multiple sclerosis victims share similar symptoms. While genetic variability and individual ability to excrete mercury probably plays a role, the causation of MS is probably multi-factorial. Very serious consideration should be given to mercury possibly playing a role in the etiology of MS.

FDAThe current scientific debate regarding the safety of amalgam dental restorations being conducted in the US is presented. The material is based on a meeting held on December 14 and 15, 2010 by the Dental Products Panel of the Medical Devices Advisory Committee of the Food and Drug Administration. The scientific and historic context of the debate is provided, followed by scientific arguments, public testimony and panel deliberations.

consumers-for-dental-choice-01In 1976, Congress directed FDA to classify (determine the risk of) every medical device. Dental fillings are a medical device. FDA proceeded to classify all filling materials except the most common one – and the most controversial one – mercury amalgam fillings. Despite letters, petitions, Congressional hearings, and a lawsuit, FDA refused to budge. FDA had no intention of doing what by law it was required to do. For 32 years, FDA defied the law.

FDAThe FDA was charged with evaluating and classifying medical devices in 1976. Amalgam manufacturers have been able to successfully shirk the burden of proving safety, which should rightfully be assigned to them. If the FDA assigns the burden to prove harm to U.S. consumer groups, the FDA condemns itself to perpetual study and inaction. This will result in an ineffective agency and an unprotected public, devastated by preventable degenerative disease.

stacy_caseFox news reporter, Stacy Case, delivers an emotional testimony at the FDA's townhall in California, September 2011. She tells of her mercury induced MS symptoms and diagnosis. The townhall, hosted by The FDA's Center's for devices and radiological health, the office within FDA that has failed to classify mercury fillings for over 33 years, despite researchers presenting scientific evidence of harm from a medical device made of 50% mercury.
