JAMA Publishes Dental Amalgam Studies

Chicago, April 18, 2006—The results of two independent and well-designed studies published in tomorrow's Journal of the American Medical Association add to the substantial body of peer-reviewed scientific literature that supports the safety of dental amalgam as an option for patients and their dentists in treating dental decay.

The published studies measure whether children with dental amalgam fillings experienced any adverse effects related to neurobehavioral, neuropsychological (IQ) and kidney function. They found that there was no difference in neurological performance and kidney function in children who have amalgam fillings compared to a control group with composite (white) fillings.

These studies support the existing scientific understanding that the minute amount of mercury released by amalgams during such common activities as eating and drinking does not affect health adversely. Both studies support the continued use of dental amalgam as an important treatment option.

Dental amalgam contains elemental mercury combined with other metals such as silver, copper, tin and zinc to form a safe, stable alloy that dentists have used for generations to restore teeth damaged by decay.

The bottom line for consumers: Dental amalgam remains among several safe, effective options for treating dental decay. Of course, the best option is still to prevent dental disease through brushing, flossing and regular dental visits. For comprehensive information about fillings and all other aspects dental care and oral health, ask your dentist and visit ADA.org.
