Research Shows BPA In Dental Sealants Safe.

Research published in the August issue of the ADA Professional Product Review shows that a 6–year–old child is exposed to more BPA from food; drinks; sunscreen, shampoo, body wash and other cosmetics; and air and thermal paper than from the amount that is in dental sealants. The ADA Science Institute staff tested the BPA release from 12 dental sealants used by dentists in the U.S. The analysis indicated that the BPA release from dental sealants is very low — .09 nanograms. This amount is well below the limit proposed for a 6–year–old child (who weighs about 20 kilograms, or 44 pounds) by the U.S. Environmental Protection Agency (1 million nanograms per day) and the European Food Safety Authority (80,000 nanograms per day). “This issue of the PPR provides a much–needed perspective on the amount of BPA in dental materials compared with other sources of exposure,” said Dr. David Sarrett, PPR editor. The publication of the PPR coincides with the August publication of a systematic review and updated clinical practice guidelines it helped generate in The Journal of the American Dental Association. Those articles give a clear indication of the benefits of the use of sealants in preventing and managing occlusal caries in children and adolescents.
