<P>PROBLEM TO BE SOLVED: To provide inorganic particles capable of providing compositions excellent in storage stability even when the composition contains an acidic group-containing polymerizable monomer and polyvalent metal-containing inorganic particles, and to provide dental compositions containing the inorganic particles. <P>SOLUTION: There are provided polyvalent metal-containing inorganic particles which are obtained by a method comprising a step for previously treating with an acid and a step for surface-treating the treated products obtained in the step with a silane coupling agent, and compositions containing the inorganic particles and an acidic group-containing polymerizable monomer. <P>COPYRIGHT: (C)2011,JPO&INPIT |
