Abstract

|
The purpose of this study was to quantify urinary and salivary bisphenol-A (BPA) concentrations according to sealant procedure among children. Nine students who had never treated with composite resin or sealant before, were recruited from one elementary school, Daegu, Korea from August 2013 to April 2014. Before sealant procedure, saliva and urine sample were collected. Immediately after sealant procedure saliva sample was collected and 24 hours after the procedure urine sample was collected. Creatinine was measured and adjusted to calculate urinary BPA concentration. Salivary and urinary BPA concentration after sealant procedure were 2.43±1.54 μg/L, 4.08±3.05 μg/g·creatinine respectively, which were relatively higher than those before sealant procedure (1.41±1.06 μg/L, 2.89±2.91 μg/g·creatinine) but these were not statistically significant. We suggest that more large scale studies considering environmental confounders which have an effect on BPA are needed to establish the relationship between sealant exposure and BPA among children.
