Study on application of rapid apatite conversion type calcium phosphate cement for pulpotomy

快速磷灰石转化型磷酸钙骨水泥(RAC-CPC)硬化时碱性较高，转变为羟基磷灰石时呈中性，无刺激作用。本研究的目的是：1.评价RAC-CPC对背侧皮下组织的影响及pH值的变化。2.从病理学角度评价RAC-CPC在牙髓修复中的应用。结果表明，RAC-CPC对牙髓有刺激作用，但不足以诱导牙髓硬组织的形成。

The rapid apatite conversion type calcium phosphate cement (RAC-CPC) becomes high alkalinity when stiffening, and it becomes neutral and shows no stimulation when it changes to hydroxyapatite. The purpose of this study was : 1. To evaluate the influence of RAC-CPC for the dorsal subcutaneous tissue and to evaluate the pH changes of RAC-CPC. 2. To evaluate pathologically on application of RAC-CPC for pulpotoiny.It was suggested that RAC-CPC have the ability to the dental pulp stimulates for pulpotomy, but not enough to induce the hard tissue formation.
