Dental resin-based composites have been the most commonly used material for dental restorations with a remarkable evolution since their inception. However, with most current composites, polymerization shrinkage and the following bacterial micro-leakage are mechanical properties that need to be improved. Therefore, filler composition has been in focus; with reductions in size that allows higher volume and provides better clinical performance and improved wear resistance. Yet this comes at a possibly harmful cost to both the dental practitioner and the patient. The polishing of the composites is done without the aid of water-cooling, leading to nanoparticles traveling unabated into the respiratory systems and through the olfactory epithelium into the brain. However, resin composite materials are considered less toxic and provide advanced esthetics, though their longevity is considered less than amalgam fillings because of recurrent caries. Looking to the future, we can expect composite materials that exhibit an antibacterial promoting layer that can help with re-mineralization of demineralized dentin, inhibit bacterial microleakage and inhibit recurrent caries with release of calcium and phosphate.
