Octacalcium phosphate (OCP) is considered to be a precursor of biological apatite crystals. The results of our previous studies showed that a new CPC setting composed of OCP and α-TCP had physical properties favorable for use in the clinical setting (OCP-mediated cement). The objective of this study is to evaluate the OCP-mediated cement as a root canal filling material for primary teeth. In this study, we evaluated the effect of particle size of powder component of OCP-mediated cement on the hardening process and sealing ability. This study has indicated that the reduction of the particle size of starting powder had a strong accelerating effect in the hydrolysis of the cement and improving the sealing ability of OCP-mediated cement.

磷酸八钙（OCP）被认为是生物磷灰石晶体的前体。我们之前的研究结果表明，由OCP和α-TCP组成的新型CPC设置具有有利于在临床环境中使用的物理特性（OCP介导的骨水泥）。本研究的目的是评价OCP介导的水门汀作为乳牙根管充填材料的效果。在这项研究中，我们评估了OCP介导的水泥的粉末组分的粒度对硬化过程和密封能力的影响。本研究表明，降低起始粉末的粒度对水泥的水解具有强烈的促进作用，并提高了OCP介导的水泥的密封能力。
