Dental microscope light improves visibility during light-curing composite application

Operating microscopes use bright light sources with a wide visible spectrum decreasing working time of light-curing restorative materials. Orange filters prevent unintended polymerization with less visibility of tooth structures and restorations. Therefore, it was the aim of the study to assess the prolongation of working time of light-curing composites by different experimental LED light-sources and to improve operating visibility with white light compared with traditional orange light.
