  • discharges
  • The Environmental Protection Agency (EPA) has promulgated pretreatment standards under the Clean Water Act to reduce discharges of mercury from dental offices into publicly owned treatment works (POTWs). (waco-texas.com)
  • The U.S. Environmental Protection Agency issued last week its pretreatment standards to reduce discharges of mercury from dental offices into publicly owned treatment works (POTWs). (lexology.com)
  • While this rule establishes pretreatment standards that require dental offices to reduce dental amalgam discharges, the rule does not require Control Authorities to implement the traditional suite of oversight requirements in the General Pretreatment Regulations that become applicable upon the promulgation of categorical pretreatment standards for an industrial category. (lexology.com)
  • These practices can prevent mercury from dental amalgam entering wastewater, wastewater sludge, and solid waste and, therefore, help to reduce the environmental impact of dental amalgam wastes and discharges. (newmoa.org)
  • practices
  • Other reasons for the decline in amalgam use include increasing use of sealants and community fluoridation, an expanding selection of fluoride-containing dental products, improved oral hygiene practices, and greater access to dental care. (medic8.com)
  • Risks of Mercury
  • In September 2006, an advisory panel to the FDA reviewed FDA's research and heard presentations from the public about the benefits and risks of mercury and amalgam. (doctorspiller.com)
  • This is an important consideration for studies seeking to determine the health risks of mercury vapor inhalation from dental amalgams," said U-M biogeochemist Joel D. Blum, a co-author of the paper and a professor in the Department of Earth and Environmental Sciences. (umich.edu)
  • FDA's
  • The FDA's action is the latest development in a long and contentious battle involving the agency, the American dental establishment, and a variety of consumer and environmental groups who argue that mercury-based amalgam fillings are potentially harmful. (medpagetoday.com)
  • FDA's new commissioner Margaret Hamburg came straight from the boardroom of America's largest seller of amalgam, Henry Schein, Inc. (mercola.com)
  • See the FDA's amalgam information page to learn more. (colgate.com)
  • Click here to read the FDA's official policy with respect to dental amalgam. (doctorspiller.com)
  • pregnant women
  • The consumer groups who originally sued the agency expressed anger at the ruling, saying the agency reneged on promises to require tougher warnings about mercury-based amalgam, particularly involving children and pregnant women. (medpagetoday.com)
  • Should pregnant women be concerned about amalgam fillings? (colgate.com)
  • However, the panel did raise concerns about the lack of knowledge concerning the effects of dental amalgam on specific groups, including pregnant women and small children. (doctorspiller.com)
  • However, as with any other medical or pharmaceutical intervention, caution should be exercised when considering the placement of any dental restorative material in pregnant women. (niom.no)
  • metals
  • So instead of letting parents know that their child is getting a dose of the most toxic and the most volatile of the heavy metals, the FDA stood as the silent partner of the pro-mercury American Dental Association. (mercola.com)

  • Amalgam is a combination of metals that has been the most popular and effective filling material used in dentistry for the last 150 years. (colgate.com)
  • Although it sometimes is called "silver amalgam," amalgam actually consists of a combination of metals. (colgate.com)
  • Dental amalgam is an unstable mixture of 50% liquid mercury with other toxic metals including copper, silver, tin. (amalgam.org)
  • But the science is clear that dental amalgam is a mixture of approximately 50% liquid mercury with various metals, including copper, silver and tin to form an unstable alloy that results in high levels of toxic metal exposure over time. (amalgam.org)
  • The strong probability of long-term clearing, with a small probability of relapse of the lichenoid tissue changes, can be assessed by performing patch testing to dental metals. (healthy.co.nz)
  • Another product development has been the greater use of noble metals such as silver, gold etc. in the amalgams. (medgadget.com)
  • Although binary alloy and ternary alloy lead the segment of alloy metals, the quaternary alloy amalgams is the fastest growing market. (medgadget.com)
  • This is due to continuous vaporization of mercury from amalgam in the mouth, along with galvanic currents from mixed metals in the mouth that deposit the mercury in the gums and oral cavity. (amalgam.org)
  • tooth
  • High dental filling can lead to pain on biting down, tooth ache and sensitivity and can further lead to TMJ problems, pain in the muscles and headache. (identalhub.com)
  • The market drivers for dental amalgam include rising cases of tooth decay caused by rise of risk factors such as high sugar diets, fast foods, sedentary lifestyles etc. (medgadget.com)
  • Because dental amalgam is neither toothcoloured nor adhesive to remaining tooth tissues, alternative tooth-coloured filling materials have become increasingly used. (niom.no)
  • alloys
  • There is no conclusive answer except that the market of dental filling materials offers a vast variety of much more credible and unequivocally better substances in a sense of outmatching biocompatibility like high content gold alloys, ceramics and certain plastic respectively cement materials, regarding the aspect of temporarily or definite solutions.

  • Another development has been the replacement of zinc with the amalgam alloys. (medgadget.com)
