Application of Polyphasic Calcium Phosphates to Direct Pulp Capping

Poly-CaP能有效地诱导硬组织形成，是因为它能从表面的可溶性磷酸钙相释放钙。Poly-CaP也被发现支持增殖并促进其表面成牙细胞样细胞的分化。Poly-CaP诱导硬组织形成的有效性可能与成牙细胞功能的激活有关。将树脂浸渍在蚀刻的HAp表面，在粘合界面上没有产生间隙，所有粘合剂都可以看到。这些结果表明了它对直接盖髓的有效性。

Poly-CaP is effective to induce hard tissue formation because of its Ca-releasing property from the soluble calcium phosphates phase on the surface. Poly-CaP was also found to support proliferation and to promote differentiation of odontblast-like cells on its surface. Activation of odontoblastic function is suggested to be involved in the effectiveness of Poly-CaP to induce hard tissue formation. Impregnation of resin into etched HAp surface, with production of no gap at the bonding interface, was seen for all adhesives. These results suggest that its usefulness for direct pulp capping.
