Sealants are effective in preventing and arresting pit-and-fissure occlusal caries lesions of primary and permanent molars in children and adolescents compared to the non-use of sealants or use of fluoride varnishes; and. Sealants can minimize the progression of non-cavitated occlusal caries lesions (also referred to as initial lesions) of the tooth that received the sealant. Although dental materials used to treat and prevent caries, including dental sealants, can contribute to very low level bisphenol A (BPA) exposure for a few hours after placement, based on current evidence, there is no health concern relative to BPA exposure from any dental material.
