Dental materials used to treat and prevent caries, including dental sealants, may contribute exceedingly low levels of bisphenol A (BPA) for a few hours after placement.8-10
In 2013, the ADA CSA adopted a statement
on BPA and dental materials.
BPA might be found in dental composites and sealants for two reasons: as a by-product generated from degradation or as a trace contaminant from materials used in the manufacture of sealants and composites. ADA research, confirmed by direct communications from dental material manufacturers, show that BPA is not used as a formula ingredient in dental materials.
The U.S. Department of Health and Human Services (HHS) provides scientific guidance on issues that affect the health of Americans, and the U.S. Food and Drug Administration (FDA) provides advice and recommendations on dental product safety. The National Toxicology Program of HHS reported that BPA in food and beverages accounts for the majority of daily human exposure.11
Based on this conclusion, in 2012, the FDA indicated that because there was sufficient uncertainty regarding human health concerns regarding BPA exposure, it would continue to provide for the use of BPA in dental materials, medical devices, and food packaging.12
Azarpazhooh and Main13
and a 2015 ADA Professional Product review14
provide the following insights for dental providers to minimize BPA exposure following dental sealant placement:
- Be sure that your curing light is function properly
- Read and follow manufacturers’ instructions
- Fully adhere to manufacturers’ curing instructions
- Use a mild abrasive, or pumice on a cotton applicator or a prophylaxis cup to reduce the possibility of unpolymerized BPA remaining on the surface
- Wash the surface of the sealant for 30 seconds with an air-water syringe with suction to remove fluids and debris from a child’s mouth
- Have older children and adults rinse with water after curing is complete
