In vitro elution of leachable components from dental sealants.
Recent concerns have been raised about the possibility that estrogenic chemicals, in particular bisphenol-A, or BPA, might be leached out of dental sealants. This study aimed to identify and quantify BPA and other components released from seven light-cured fissure sealants in vitro. None of the tested sealants was shown to have released BPA; however, the investigators identified other eluted components that should be investigated for their biological effects.
