PROBLEM TO BE SOLVED: To provide a dental restorative material composition providing a cured product after curing having high mechanical strength, polishing performance and luster durability of and shine and good operability.SOLUTION: There is provided a dental restorative material composition which comprises a (meth)acryl amide compound (A) represented by the following formula (1), a polymerizable monomer excluding the compound (A) and an acidic group-containing polymerizable monomer, a filler (C) composed of fine particles having an average particle diameter of 0.10 to 1.0 μm and a polymerization initiator (D). [Rrepresents H or a methyl group; X represents H or an aliphatic group having 1 to 3 carbon atoms; Y represents -R-OR; Ran aliphatic group having 1 to 10 carbon atoms; Rrepresents H or an aliphatic group having 1 to 4 carbon atoms; an aliphatic group of X, Rand Rmay be interrupted by a bonding group such as -O-, -NR- and -CO-NR-; Rrepresents H or an aliphatic group having 1 to 6 carbon atoms; X and Y may form a nitrogen-containing monocyclic heterocycle via R(provided that X and Y do not form a heterocycle and X is an aliphatic group.] |
