The World Health Organization Dental Amalgam Review

The World Health Organization recommends a global phase out of dental mercury.   In the WHO’s  newly released  2009 report on “Future Use of Materials For Dental Restorations”.  This is a great article by Charlie Brown from Consumers for Dental Choice.  You can find a full view of the WHO Dental Materials report here.

In a clear sign that dentistry’s amalgam era is fading, the World Health Organization (“WHO”) just released its long-awaited report on dental amalgam. In Future Use of Materials for Dental Restoration, WHO urges “a switch in use of dental materials” away from amalgam.

“[F]or many reasons,” WHO explains, “restorative materials alternative to dental amalgam are desirable.” The report describes three of these reasons in detail:

  • WHO determines that amalgam releases a “significant amount of mercury”: WHO concludes that amalgam poses a serious environmental health problem because amalgam releases a “significant amount of mercury” into the environment, including the atmosphere, surface water, groundwater, and soil. WHO says “When released from dental amalgam use into the environment through these pathways, mercury is transported globally and deposited. Mercury releases may then enter the human food chain especially via fish consumption.”
  • WHO determines that amalgam raises “general health concerns”: While the report acknowledges that a few dental trade groups still believe amalgam is safe for all, the WHO report reaches a very different conclusion: “Amalgam has been associated with general health concerns.” The report observes, “According to the Norwegian Dental Biomaterials Adverse Reaction Unit, the majority of cases of side-effects of dental filling materials are linked with dental amalgam.”
  • WHO determines that “materials alternative to dental amalgam are available”: WHO concludes that “Materials alternative to dental amalgam are available” – and cites many studies indicating that they are superior to amalgam. For example, WHO says “recent data suggest that RBCs [resin-based composites] perform equally well” as amalgam. And compomers have a higher survival rate, says WHO, citing a study finding that 95% of compomers and 92% of amalgams survive after 4 years. Perhaps more important than the survival of the filling, WHO asserts that “Adhesive resin materials allow for less tooth destruction and, as a result, a longer survival of the tooth itself.”

We have come a long way. Less than a year ago, dental trade groups were circulating an unedited and unreviewed draft of this report to government officials, implying that it was WHO’s final position. But the draft was riddled with factual errors and scientifically unsupported claims. Consumers for Dental Choice – working with non-governmental organizations, scientists, and environmentalists from around the globe – organized a letter-writing campaign to insist that the draft be immediately withdrawn, accurately rewritten, and properly reviewed.

And it worked! Now WHO has removed all claims of amalgam’s safety. Now WHO has committed itself to “work for reduction of mercury and the development of a healthy environment.” Now “WHO will facilitate the work for a switch in use of dental materials.”

Thank you to everybody who urged WHO to take this important step to protect future generations from dental mercury.

Global Mercury Treaty May Include Ban on Mercury in Medicine

07/25/2011 by Leave a Comment
SILVER SPRING, Md., August 1, 2011 /PRNewswire-USNewswire/ – CoMeD –

On Friday, July 22, 2011, the United Nations Environment Programme (UNEP) distributed a revised text for its comprehensive global treaty on mercury. Advocates for mercury-free drugs were gratified to see pharmaceuticals listed in “Annex C (Mercury-added product not allowed)” of the proposed treaty.

 

The Coalition for Mercury-free Drugs (CoMeD) helped initiate this addition through its advocacy efforts at the United Nations (UN) negotiations held in Chiba, Japan in January 2011. CoMeD President Rev. Lisa Sykes, the mother of a son diagnosed with vaccine-related mercury poisoning, described to representatives of over 150 participating nations how: “… unnecessarily injecting mercury into pregnant women and children, as part of a vaccine or other drug, is an ongoing and often unrecognized crisis.”

 

Thimerosal (49.6% mercury by weight), still used as a vaccine preservative and in-process sterilizing agent, is an unnecessary, and sometimes undisclosed, component in many vaccines. Its use is associated with neurodevelopmental disorders, cancer, birth defects and miscarriage. Those harmed most by Thimerosal in vaccines are the unborn and newborn.

 

Addressing the diplomats attending the UN meeting in Chiba, Dr. Mark R. Geier of CoMeD observed: “For this treaty to be fully effective, it must make clear that the intentional exposure of humans, especially pregnant women and young children, to mercury, will not be tolerated.”

 

Dr. Geier’s comments were especially well-received by the diplomats from developing nations. CoMeD representatives met with regional working groups in closed-door sessions and explained the feasibility of using 2-phenoxyethanol, a much less toxic alternative to Thimerosal, in vaccines and other drugs.

 

Dr. Geier challenged the inequity of providing wealthy nations with vaccines having reduced levels of mercury while poor nations still receive vaccines containing dangerously high levels of mercury: “Children around the world, no matter their place of birth or their income level, deserve safe mercury-free vaccines. The practice of providing mercury-reduced and mercury-free vaccines to developed countries while insisting that developing nations take mercury-containing ones is wrong.”

By the end of negotiations in Chiba, diplomats from developing countries requested the Secretariat to assess the safety of mercury in drugs.

 

A team of scientists and advocates from CoMeD will attend the next treaty negotiation in Nairobi, Kenya from October 31 through November 4, 2011, to support keeping this global ban on mercury-containing drugs in the finalized UN treaty.

The U.S. Calls for the Phase-Out of Amalgam Ultimately

06/06/2011 by Leave a Comment

The U.S. Calls for the Phase-Out  of  Amalgam Ultimately.

In an extraordinary developments that will change the global debate about amalgam, the United States government has announced that it supports a “phase down, with the goal for eventual phase out by all Parties, of mercury amalgam.” This statement- a radical reversal of its former position that “any change toward the use of dental amalga is likely to result in poitive public health outcomes” — is part of the U.S. government’s submission for the upcoming third round of negotiations for the world mercury treaty.*

While couched in diplomatic hedging — remember it is still early in the negotiations — this new U.S. position makes three significant breakthroughs for the mercury-free dentistry movement:

The U.S. calls for the phase-out of amalgam ultimately and recommends actions to “phase down” its use immediately.  Incredibly, the government adopted three actions that the World Alliance for Mercury-Free Dentistry and Consumers for Dental Choice proposed at the negotiating session in Chiba, Japan.  Our key ally, The Mercury Policy Project, laid the groundwork for this success at a World Health Organization meeting in 2009!

The U.S. speaks up for protecting children and fetuses from amalgam, recommending that the nations “educate patients and parents in order to protect children and fetuses.”

The U.S. stands up for the human fight of every patient and parent to make educated decisions about amalgam.

What does this mean?  Our position — advocating the phase-out of amalgam — is now the mainstream because the U.S. government supports it.  Who is the outlier now?  It’s the pro-mercury faction, represented by the World Dental Federation and the American Dental Association.  With the U.S. continuing its leadership role in this treaty, we will broadcast the U.S. position to other governments around the world, encouraging them to support amalgam “phase downs” leading to phase-outs not only globally, but within each of their countries.

 

We applaud the U.S. government.  But tough work lies ahead.  For example, we must demonstrate to the world that the available alternatives — such as composites and the adhesive materials used in  atraumatic restorative treatment (“ART”) — can cost less than amalgam and will increase access to dental care particularly in developing countries.

 

For now though, let’s mark this watershed in the mercury-free dentistry movement: the debate has shifted from “whether to end amalgam” to “how to end amalgam.”
