Composite fissure sealant safety?

Very safe but: Sealants manufactured in the us are safe to place on teeth and can be very beneficial. I recently read an artiicle in a peer review magazine that some sealants manufactured outside the us had detectable levels of bisphenol a (bpa) in extreamly low levels. Bpa from composite fillings and sealents manufactured outside the us should be avoided since there is some concern.
