Evidence indicates dental materials not a Bisphenol A exposure risk

By Craig Palmer The latest peer-reviewed evidence indicates consumers are not at risk from Bisphenol A exposure through the use of dental materials, the Association said in a May 23 communication with government scientists studying the synthetic compound.
"We are aware that some dental sealants— and to a lesser extent dental composites— potentially could contribute to low levels of BPA exposure," the ADA said. "For that reason, we have asked the Dental Trade Alliance and its member companies for information on the potential for BPA exposure from their products.
"Consumers must be assured that the materials used to maintain oral health are safe," said the letter signed by ADA President Mark J. Feldman and sent to the National Institute of Environmental Health Sciences, one of the National Institutes of Health. The institute's National Toxicology Program is conducting a comprehensive review of BPA and its use in producing certain types of plastic.
"The Association supports the practice of informing consumers when BPA is used as a dental product ingredient," the letter said. "We further support calls for additional research into human exposure to BPA and any health effects it may cause."
A recent NTP interim draft report is based on a 2007 report of an expert panel, which characterized the leaching of BPA from dental sealants as an "infrequent event with little relevance to estimating general population exposures."
More information on Bisphenol A and dental sealants and composites is available on ADA.org.
