Summary
The Composites and Urinary Bisphenol-A Study (CUBS) is a clinical study of dental composite for its effects on urinary bisphenol-A levels. The study will enroll approximately 139 children recruited from study-affiliated clinical sites in New England.The primary aim of CUBS is to test the hypothesis that urinary bisphenol-A (BPA) concentrations increase after composite restoration placement. BPA is a chemical used in the synthesis of matrix monomers and has been shown to have harmful effects in toxicological studies in laboratory animals. Currently it is unknown whether dental composite restorative materials containing monomers that are derived from BPA result in chronic low-dose BPA exposure in children.
