In vivo bisphenol-A release from dental pit and fissure sealants: A Systematic Review

Conclusions The available evidence on this topic derived from studies that represent a moderate level of evidence. Nevertheless, the available evidence supports that BPA is released in saliva after sealant placement. Clinical significance From the qualititative and quantitative synthesis of studies, it is reasonable to conclude that BPA is released after placement of some dental pit and fissure sealants in the oral cavity. The biggest quantities are detected in saliva immediately after or one hour after their placement. (Source: Journal of Dentistry)
