    摘要： An objective of the present invention is to provide a dental restorative material composition using an organic-inorganic composite filler having excellent surface smoothness like a natural tooth and low polymerization shrinkage. The dental restorative material composition has excellent X-ray contrast imaging property and similar transparency to that of a natural tooth, where the transparency is not varied before and after the composition is hardened. The dental restorative material composition includes (a) a (meth)acrylate monomer, (b) an organic-inorganic composite filler having an average particle diameter of 5 to 50µm, which is made by mixing a (meth) acrylate monomer and a fine particle filler having an average primary particle diameter of 0.005 to 0.3µm and having X-ray impermeability and hardening and pulverizing the mixture, (c) a fine particle filler having an average primary particle diameter of 0.005 to 0.04µm, and (d) a photopolymerization initiator.

    摘要： This is to provide an organic and inorganic composite filler to yield excellent surface smoothness similar to that of a natural tooth and to cause low polymerization shrinkage when used for a dental restoration material composite, and to acquire a dental restoration material composite having high X-ray imaging property and high mechanical strength. The organic and inorganic composite filler used for a dental restoration material is produced by curing and pulverizing a (meth)acrylate compound including 50 to 80% by weight of a glass powder having a maximum particle diameter of 5µm or less, an average particle diameter from 0.05 to 2µm, and X-ray imaging property, and 10 to 40% by weight of a metal compound having an average particle diameter from 0.005 to 0.3µm and X-ray imaging property, where the (meth)acrylate compound includes 90% by weight of both the glass powder and the metal compound at the maximum. The organic and inorganic composite filler has preferably an average particle diameter from 10 to 30µm.

    摘要： To provide fluoroaluminosilicate glass powder enabling to improve acid resistance of dental glass ionomer cement and a production method thereof.
    [Solution]
    A lanthanum compound eluted in the presence of polycarboxylic acid and water exists only in a surface layer of a fluoroaluminosilicate glass powder. An amount of the lanthanum compound is preferably 1 to 5 % by weight in terms of oxide. The fluoroaluminosilicate glass powder is produced by mixing an aqueous solution of a lanthanum compound and a fluoroaluminosilicate glass powder not containing lanthanum, and heating them. The aqueous solution of lanthanum compound is an aqueous solution of a water solvable lanthanum compound, preferably an aqueous solution of lanthanum nitrite and/or an aqueous solution of lanthanum chloride.
