Summary: | A calcium phosphate cement and a calcium phosphate cement composition are disclosed. The calcium phosphate cement comprises a calcium phosphate powder having an average particle diameter of 20 mu m or smaller and a tap density of 35% or higher, and a polysaccharide. The polysaccharide is preferably a dextran sulfate (e.g., dextran sulfate sodium) having an average particle diameter of 0.1 to 100 mu m. The calcium phosphate cement composition comprises the above specific calcium phosphate powder and a liquid for cement mixing comprising an aqueous solution containing 30 to 60 wt% dextran sulfate (e.g., dextran sulfate sodium or dextran sulfate potassium). The calcium phosphate powder preferably comprises a tetracalcium phosphate powder and an equimolar amount of a calcium hydrogen phosphate powder as main components. |
