Process for filling dental cavities with radiation curable silaneous adhesives comprising a polymerizable resin comprising at least 20% by weight of a polymerizable silane and optionally up to about 80% by weight of a polymerizable, ethylenically unsaturated material. According to a preferred embodiment, the polymerizable silane is either an acrylosilane or a vinyl silane.

Process for filling teeth

Dental restorative composition are provided having improved color stability. According to a preferred embodiment, such compositions comprise a blend of a major proportion of inorganic, particulate filler, and a minor proportion of a resin component comprising a binder resin, a diluent monomer and a three part photosensitizing system comprising an alpha diketone, an amine reducing agent, and a benzoin alkyl ether. The superior color stability and other properties of restorative compositions of this invention are believed to result from synergistic interactions among the components of the sensitizing system.
