Photoactive Material Could Ease Dental Woes
VIENNA, May 1, 2014 — A visit to the dentist may not be the most fun experience, but a new material could make it more tolerable. A new generation of dental filling materials that harden more quickly under blue light has been developed by a team at the Vienna University of Technology, in collaboration with Ivoclar Vivadent New York and additional testing by Graz University of Technology. The new composite material includes germanium-based molecules added to inorganic fillers and photoactive organic
