BPA in dental sealants safe
August 01, 2016
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 (such as cash register receipts) 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.
“Dental sealants offer a tremendous oral health benefit to children and should continue to be a routine preventive service,” said Dr. Sarrett.
In addition to the BPA article and its corresponding laboratory reports, the August PPR includes an expert panel
discussion about BPA, and an essay
about the BPA released from resin-based dental sealants from the Council on Scientific Affairs’ caries workgroup.
