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. Graeme Munro-Hall B.D.S mercury related heart problems and UNEP work Dr. Graeme Munro-Hall BDS discusses his mercury related heart problems and his work towards banning dental mercury amalgam by participating in the United Nations Environment Program (UNEP).

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.
Affordable Dental Office Mercury Screening by Mercury Instruments USA 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.
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.
A Review of the ADA Mercury Hygiene Recommendations This article reviews and elaborates on the ADA’s 15-point mercury safety guidelines. Common workplace violations are highlighted, and steps for correction are cited. Practitioners can utilize this information to assist in development of an office protocol.

Discusses occupational Exposure to Mercury


Get training from your employer as required by OSHA standards.

  • Get training from your employer on chemicals you are exposed to during your work and information on how to protect yourself from harm. Employers must establish a comprehensive, written hazard communication program (Chemical Hazard Communication) Your employer must label chemical containers, make material safety data sheets with detailed hazard information available to employees, and train you about the health effects of the chemicals you work with and what the employer is doing and what you can do to protect yourself from these hazards.
  • The program must list the hazardous chemicals in each work area, how the employer will inform employees of the hazards of non-routine tasks (for example, the cleaning of reactor vessels), and hazards associated with chemicals in unlabeled pipes and how the employer will inform other employers at a multi-employer worksite of the hazards to which their employees may be exposed.

Request information from your employer about OSHA standards, worker injuries and illnesses, job hazards and workers' rights.

    • Request information from your employer on safety and health hazards in your workplace, chemicals used in your workplace, tests your employer has done to measure chemical, noise and radiation levels, precautions you should take and procedures to be followed if you or other employees are involved in an incident or are exposed to hazardous chemicals or other toxic substances.
    • Request copies of appropriate standards, rules, regulations and requirements that your employer should have available at the workplace.
    • Review the Log and Summary of Occupational Injuries and Illnesses (OSHA 300) at a reasonable time and in a reasonable manner or have an authorized representative do so for you. (29 CFR 1904.7)
    • Employers must inform you of the existence, location and availability of your medical and exposure records when you first begin employment and at least annually thereafter. Employers also must provide these records to you or your designated representatives within 15 working days of your request. When an employer plans to stop doing business and there is no successor employer to receive and maintain these records, the employer must notify you of your right of access to records at least 3 months before the employer ceases to do business.
    • Observe any monitoring or measuring of toxic materials or chemicals, as well as harmful physical agents, such as noise, and see the resulting records. If the exposure levels are above the OSHA limit, the employer must tell you what will be done to reduce the exposure -- the right to observe monitoring exists only where monitoring is performed pursuant to a standard that provides employees with the right to observe.


Request action from your employer to correct hazards or violations.

    • You may ask your employer to correct hazards even if they are not violations of specific OSHA standards. Be sure to keep copies of any requests you make to your employer to correct hazards.

File a complaint with OSHA if you believe that there are either violations of OSHA standards or serious workplace hazards.

    • Request in your written complaint that OSHA keep your name confidential if you do not want your employer to know who filed the complaint. (OSH Act, Section 8)

Be involved in OSHA's inspection of your workplace.

    • Have an authorized employee representative (such as a union representative) accompany the OSHA compliance officer during the inspection tour. (OSH Act, Section 8), (29 CFR 1903.8)The authorized employee representative has a right to accompany an OSHA compliance officer (also referred to as a compliance safety and health officer (CSHO) or inspector) during an inspection. Under no circumstances may the employer choose the workers' representative. Where there is no union or employee representative, the OSHA inspector must talk confidentially with a reasonable number of workers during the course of the investigation.
    • Respond to questions from the compliance officer and tell the compliance officer about workplace hazards, particularly if there is no authorized employee representative accompanying the compliance officer on the inspection "walkaround." (OSH Act, Section 8)You and your coworkers have a right to talk privately and confidentially to the compliance officer whether or not a workers' representative has been chosen. You may point out hazards, describe injuries or illnesses or near misses that resulted from those hazards and describe past complaints about hazards. Inform the inspector if working conditions are not normal during the inspection. Make sure that the inspector is aware if equipment has been shut down, windows opened or other conditions changed from normal.

Find out results of an OSHA inspection.

    • Find out the results of OSHA inspections and request a review if OSHA decides not to issue a citation. (CPL 2.115)If health hazards are present in your workplace, a special OSHA health inspection may be conducted by an industrial hygienist. This OSHA inspector may take samples to measure levels of chemicals or other hazardous materials. OSHA will let the employee representative know whether your employer is in compliance. The inspector also will gather detailed information about your employer's efforts to control health hazards, including results of tests your employer may have conducted.

Get involved in any meetings or hearings to discuss any objections your employer has to OSHA's citations or to changes in abatement deadlines.

File a formal appeal of deadlines for correction of hazards.

    • File an appeal of the deadlines that OSHA sets for your employer to correct any violation in the citation issued to the employer. Write to the OSHA Area Director within 10 working days from the date the employer posts the notice requesting on extension of the abatement deadline if you feel the time is too long. (29 CFR 1903.17)

File a discrimination complaint.

    • File a discrimination complaint (under Section 11(c) of the OSH Act) within 30 days if you are punished or discriminated against for exercising your safety and health rights or for refusing to work (not guaranteed by the OSH Act) when faced with an imminent danger of death or serious injury and there is insufficient time for OSHA to inspect.

Request a research investigation on possible workplace health hazards.

  • Contact the National Institute for Occupational Safety and Health (NIOSH) to request a health hazard evaluation if you are concerned about toxic effects of a substance in the workplace.
  • Provide comments and testimony to OSHA during rulemaking on new standards.

NOTE: States with OSHA-approved state plans (23 states and territories, plus two plans limited to public employees) provide at least the same rights and protections (and in some cases additional rights) to workers, although they may follow slightly different procedures.

mercury-exposure-avatarFor years I've read news stories about dental mercury amalgam fillings that failed to ask vital follow up questions for one to form a better understanding of the true risks involved with exposure to mercury fillings. Rarely was a toxicologist, neurologist or bio-chemist interviewed. Instead, the stories would always give dentists such prominence when promoting the safety of a substance of which they knew nothing about, all while never acknowleding the much lower levels of mercury at which our government has removed other products from the market. So now I'm doing what I can to help raise awareness of the many dangerous aspects of dental mercury fillings.
