<P>PROBLEM TO BE SOLVED: To provide a calcium phosphate composition showing time from the addition of a liquid agent to the calcium phosphate composition till the setting, namely the setting time within an appropriate range and exhibits a good marginal sealability in using it in a clinical environment. <P>SOLUTION: The calcium phosphate composition contains tetracalcium phosphate particles (A1), acidic calcium phosphate particles (A2), and inorganic particles (D) other than (A1) and (A2). The average particle size of the inorganic particles (D) ranges 0.002 to 2 μm, and 1 to 30 pts.wt. of the inorganic particles (D) are contained based on 100 pts.wt. of the acidic calcium phosphate particles (A2), and the acidic calcium phosphate particles (A2) contain acidic calcium phosphate composite particles covered with the inorganic particles (D). <P>COPYRIGHT: (C)2009,JPO&INPIT |
