Bisphenol-A free dental polymeric materials

Bisphenol-A (BPA) is suspected to be an endocrine disrupter. Current polymeric dental materials are based on BPA derivatives, for example, Bisphenol-A diglycidylether methacrylate (Bis-GMA) which may leach out unreacted monomers and their degradation products. Consequently, the objective of the present work was to study the properties of BPA-free alternatives, for potential use in dental polymers and composites. Experimental results indicated that BPA-free monomers from natural and commercial sources can replace Bis-GMA with adequate physical and mechanical properties of the final dental polymeric adhesives and composites.
