Dr. Hal Huggins' Comments on the ADA's Handling of Scrap Amalgam
The American Dental Association held its 148th Annual Session in San Francisco, California. in October 2007 and issued press releases concerning mercury amalgam separators and their plans for writing an "accurate" patient brochure about filling materials. The ADA claims that web sites such as mine (MercuryPoisoned.com), Consumers for Dental Choice (ToxicTeeth.org), Dental Amalgam Mercury Syndrome or DAMS (Amalgam.org), the International Academy or Oral Medicine and Toxicology (IAOMT.org) and a host of others coming out of the woodwork telling their mercury poisoning stories is confusing the public.An ADA press release about the proposed "scientifically accurate" patient brochure states:
Despite a wealth of scientific evidence supporting the continued availability of amalgam as a safe and effective treatment option, both the mainstream media and the Internet frequently carry confusing and incorrect information about amalgam. The ADA hopes, through production of this brochure, to provide all dentists and their patients with scientifically accurate information about dental materials to aid them in making informed treatment choices.
You can read the press release about the patient brochure in links further down this web site. But the purpose of this article is to discuss the amalgam mercury separators.
According to the press release, "the ADA has updated its best management practices for the disposal of dental amalgam waste to include the use of separators, collection devices installed in dental office plumbing to capture and remove at least 95 percent of solid waste particles before they enter the sewer system."
Hal Huggins, DDS humorously commented on previous ADA recommendations about disposing of scrap amalgam on page 36-37 of his book It's All in Your Head, published in 1986.
How Much is too Much for a Dentist? by Dr. Hal Huggins
Mercury Amalgam Separator--
is placed under the dentist's sink to stop mercury waste from collecting in the drain trap and going into the city waste water. Dr. Steve Marcus of New Jersey testified before the FDA Advisory panel in 2006 that he collected between 3 to 5 pounds of mercury per year in his separator. Most states do not require dentists to use an amalgam separator because lawmakers receive many contributions from the states' dental associations. In Virginia, the "good old boys" legislators don't want to infringe on the business practices of the dentists. Some of the New England states have taken a lead and passed legislation to require the use of amalgam separators.
Here is the press release from the ADA about their updating their best management practices to include an amalgam separator:
ADA Updates Environmental Recommendations for Handling Waste
SAN FRANCISCO, Oct. 2, 2007 /PRNewswire-USNewswire/ -- The American Dental Association (ADA) has updated its best management practices for the disposal of dental amalgam waste to include the use of separators, collection devices installed in dental office plumbing to capture and remove at least 95 percent of solid waste particles before they enter the sewer system. The use of separators will allow greater recycling and reduce the amount of amalgam, which contains mercury, entering wastewater treatment plants.
"Dentists across the country have enthusiastically embraced ADA best management practices since we introduced them in 2003, which clearly demonstrates that voluntary programs work," said ADA President Mark J. Feldman, DMD. "Since then, we have gained a lot of experience with separator technology, and even assisted the ISO (an international standard-setting organization) in developing standards for the devices. We have learned that the systems work well, and we now feel comfortable including them in our best management practice recommendations."
Dental amalgam is a silver-colored alloy made from mercury, silver, copper and tin that dentists have used for generations to fill decayed teeth. Once the most commonly used filling material, it has been surpassed in popularity by tooth-colored composites. It nevertheless remains a safe and valued treatment option for some patients, particularly those needing large fillings in back teeth or who have special needs.
Dental offices using ADA best management practices already capture about 80 percent of waste amalgam. Adding separators to that regimen would increase the amount of captured amalgam to at least 95 percent. The additional amalgam captured by the separator would otherwise have been captured downstream by the municipal wastewater treatment plant. However, treatment plant waste is often incinerated; amalgam captured by separators can be recycled.
"Like most people, dentists are committed to protecting the environment," said ADA Executive Director Jim Bramson, DDS. "By adding separators to their best management practices, dentists have much greater control in their efforts to ensure a healthier environment for everyone."
The ADA just concluded its 148th Annual Session here.
The not-for-profit ADA is the nation's largest dental association, representing more than 155,000 dentist members. The premier source of oral health information, the ADA has advocated for the public's health and promoted the art and science of dentistry since 1859. The ADA's state-of-the-art research facilities develop and test dental products and materials that have advanced the practice of dentistry and made the patient experience more positive. The ADA Seal of Acceptance long has been a valuable and respected guide to consumer and professional products.
