摘　　要：目的 探讨牙本质非胶原蛋白与羟基磷灰石矿化作用 方法 在体外矿化系统中利用人牙本质非胶原蛋白与羟基磷灰石结合进行诱导矿化实验，通过扫描电镜观察生成物的形貌变化，X线衍射及等离子发射光谱分析生成物的组分和结构。结果 结合有人牙本质非胶原蛋白的羟基磷灰石表面有矿化物形成，该矿化物钙磷比约为1.33，其X线衍射结果与钙磷灰石更为相似。结论 人牙本质非胶原蛋白与一定的支持物紧密结合后具有诱导矿化的作用。Objective To study the dentin non-collagenous proteins and hydroxyapatite mineralization method in vitro system using human mineralized dentin non-collagen protein in conjunction with the induction of hydroxyapatite mineralization experiment s, by scannin g electron microscopy resultant Changes in morphology, X-ray diffraction and plasma emission spectrometric analysis of the composition and structure of theresultant. Results combined with some dentin non-collagen protein mineralization of hydroxyapatite to form the surface of the mine compounds of calcium and phosphorusratio of about 1.33, the X-ray diffraction results are more similar to calcium hydroxyapatite. Co nclusion dentin non-collagen protein and some support materials in close combination with the role of induction of mineralization.
