Abstract
Provided is a filling/restoring material, including a photopolymerization initiator of a quaternary system formed by combining an α-diketone compound, an aliphatic amine compound, an aromatic amine compound, and a photoacid generator, in which even when the filling/restoring material is filled and cured on a cured layer of a dental adhesive material including a radical-polymerizable monomer having an acidic group, the filling/restoring material undergoes sufficient curing up to a contact interface between the filling/restoring material and the cured layer, thereby providing high adhesive strength stably. Also provided is a dental filling/restoration kit, including: a filling/restoring material including: a polymerizable monomer having no acidic group; a basic inorganic material; and a photopolymerization initiator formed by at least combining: an α-diketone compound; an aliphatic amine compound; an aromatic amine compound; and a photoacid generator; and an adhesive material, which is used for adhesion between a tooth and the filling/restoring material by curing the adhesive material before filling the filling/restoring material, the adhesive material including: a polymerizable monomer including a polymerizable monomer having an acidic group; and a polymerization initiator.
