Self-setting cements, αD-Cement and αDT-Cement, were prepared. They consisted of only the calcium phosphates α-TCP, TTCP and DCPA. These cements reacted and hardened in a moist environment at 37°C. The powder X-ray diffraction patterns were taken to examine the conversion of their reactions as a function of time. The cements reacted and produced hydroxyapatite. The optimum powder/liquid ratio of aD-Cement was 2.0 and that of αDT-Cement was 1.8. The initial setting time of αD-Cement was 87.5 m and that of aDT-Cement was 107.5 m. The component and the product of these cements are calcium phosphates which are the putative minerals in teeth and bones. Therefore, these cements are useful for oral surgery as bone-filling materials
