Monomers from Resin-Based Materials: Risk Assessment In Dental Medicine

Resin composites, which are commonly used in restorative dentistry, consist of a cross-linked polymer matrix and fillers at 60 to 80 % by weight. The resins used are generally made of very large molecules, like bisphenol A glycidyl methacrylate (BIS-GMA), a highly viscous component. In view of reducing the composite's viscosity and improving its handling properties, other components are usually added, such as the diluent tri-ethylene glycoldimethacrylate (TEGDMA). The mineral fillers should be of very small size and treated on their surface by a silane coupling agent, which is added and linked to the particles in order to achieve strong bonding with the resin during polymerization
