Nanotechnology can be used to create new materials with superior properties. Solar cells, cancer drugs and now the visit to the dentist office could be a bit better (well still no fun!). New dental materials are being created. “These resin-based composites (RBCs) containing nanoparticles exhibit a high surface free-energy that exerts differential behavior in terms of mechanical and physicochemical properties, such as an excellent color density, low polymerization shrinkage, adequate surface brightness, low surface roughness, resistance to fracture, and excellent adherence to dental tissues,” wrote the authors. Wow that is a mouthful. Translation? The stuff that they use to repair cavities and damaged teeth is going to be better, smoother and more like real teeth.
