摘要

Five uncured commercial dental resin composites (two bis-glycidyl methacrylate based products and three non-bis-glycidyl methacrylate based products) were examined for contamination with bisphenol A, which is a known xenobiotic. After the samples were processed with acetonitrile for extraction of their components, high performance liquid chromatography analysis was performed and the eluted peaks were fractionated for comparison using UV spectra. The results suggested that all the resin composites tested were contaminated with bisphenol A or its derivatives. Theoretically, bisphenol A is not a component of dental resin composite, but it could remain as an impurity of the composite during the synthesis of Bis-GMA. The results suggest that it is necessary to investigate the ability of this impurity and its derivatives in dental resin composites to cause estrogenic effects, as well as to evaluate the release of the impurity from cured resin composites.
