CHICAGO, Feb. 25, 2010—The American Dental Association (ADA) joins with the FDI World Dental Federation's recent "Resolution on Dental Amalgam," reiterating that dental amalgam is a safe, effective and affordable dental filling material that serves the oral health needs of the majority of communities around the world, particularly those most disadvantaged and in need of dental treatment.

The FDIWorld Dental Federation is a membership organization, comprised of more than 200 worldwide national dental associations and specialist groups, altogether representing more than one million dentists globally.

In the resolution, passed by the FDI General Assembly late in 2009, FDI acknowledges its responsibilities with regard to mercury and the environment, reaffirming "its commitment to upholding best environmental practices with regard to dental amalgam." The ADA likewise supports use of its own best management practices (BMPs) for the handling and disposal of waste dental amalgam and is engaged in ongoing efforts, partnering with the United States EPA, to promote those BMPs.

FDI stresses that other currently available dental filling materials may not represent "economically viable, affordable alternatives in many circumstances, most particularly in developing countries where the use of alternatives may present additional clinical, logistical, economic and infrastructure challenges."

The ADA shares the concern expressed by FDI, that "general restrictions governing the use of mercury may lead to a significant global public health problem, with respect to the delivery of dental care."

Dental amalgam is a cavity-filling material made by combining mercury with other metals such as silver, copper and tin. Numerous scientific studies conducted over the past several decades, including two large clinical trials published in the April 2006 Journal of the American Medical Association, indicate dental amalgam is a safe, effective cavity-filling material for children and others. And, in its 2009 review of the scientific literature on amalgam safety, the ADA's Council on Scientific Affairs reaffirmed that the scientific evidence continues to support amalgam as a valuable, viable and safe choice for dental patients. In 2009, the U.S. Food and Drug Administration likewise concluded that dental amalgam is a safe and effective treatment option.

The FDI's environmental concerns are consistent with those of the ADA. In addressing these concerns, the ADA was in the forefront of developing and implementing best management practices for disposal of dental amalgam waste.
