Abstract
Photocurable restorative materials for making dental restorations usually are highly filled with fillers such as amorphous silica, quartz or glass powder having limited translucency to curing radiation. Thus the underside of the restoration may not become adequately photocured. Better curing at the underside is achieved by applying a coating of fluorescent or reflective material beneath the restorative material. When exposing the restorative material to radiant curing energy, the resulting fluorescence or reflectance by the coating enhances the degree of cure of the underside of the restoration.
