PROBLEM TO BE SOLVED: To provide a surface-modified dental inorganic filler which is obtained by using two different types of fillers to form a composite, in order to improve transparency of a dental composition, and to provide a dental composition comprising the dental composite inorganic filler.SOLUTION: A dental composite inorganic filler is obtained by mixing and pulverizing an inorganic filler (A) having an average particle diameter of 1 μm or more and an inorganic filler (B) including at least one inorganic material different from the inorganic filler (A) and having an average particle diameter of 0.04 μm or less, to produce a composite.COPYRIGHT: (C)2014,JPO&INPIT【課題】歯科用組成物の透明性を向上させるため、異なる2種類のフィラーを用いて複合化することにより、表面改質された歯科用無機充填材、及び該歯科用複合化無機充填材を含有してなる歯科用組成物を提供すること。【解決手段】平均粒子径が1μm以上である無機充填材(A)と、該無機充填材(A)とは異なる無機物を少なくとも1種含み、平均粒子径が0.04μm以下である無機充填材(B)とを混合粉砕による処理によって複合化してなる歯科用複合化無機充填材。【選択図】なし
