Résumé : Dental resin composites have seen increasing use in recent years due to their ease of use and advantageous aesthetic properties when compared to the mercury containing dental amalgams.  The principal monomer used in current dental resin composites called bisphenol A glycerolate dimethacrylate (BisGMA) is made from bisphenol A, and exhibits toxicity at moderate concentrations, as well as an unfavourable volumetric shrinkage.  This research work aims to replace these monomers with new biomaterials based on bile acids with superior mechanical and toxicological properties.  In addition, many fillers are being synthesized and tested in order to optimize the composite formulations to understand the effect of different parameters on the final material properties.
