Overview

Adult patients who require multiple dental restorations will be included in this study. Urine and saliva samples will be taken for determination of bisphenol A levels at several time points, and for analysis of the estrogenic activity using ERE-CALUX.

Also buccal cells will be taken. Next, DNA extraction will be done with a commercial kit. We will determine global alterations in DNA methylation and DNA hydroxymethylation levels using UPLC-MS/MS.
