A development of the bonding treatment of vertically fractured roots with periodontal regeneration adhesive resin using tissue engineering

为了加强垂直折断牙根的粘结治疗，我们的目标是在树脂和牙本质粉的混合物上形成新的牙骨质，或β-TCP，它可以改善树脂和牙骨质之间的粘结。体外细胞毒性测定。它的细胞毒性很小。在体内，我们观察了含有β-TCP的树脂上新形成的硬组织和培养的骨髓基质细胞片。这项实验可能显示出在树脂上形成新的硬组织的可能性。

To enhance the bonding treatment of vertically fractured roots, we aimed to the newly cementum formation on a compound of resin and dentin powder, or β-TCP which may improve the binding between resin and cementum. In vitro, cytotoxicity was assessed. It had little cytotoxicity. In vivo, we observed the newly hard tissue formation on a resin containing β-TCP applied by rhBMP-2 and cultured bone marrow stromal cell sheets. This experiment might exhibit a possibility of the newly hard tissue formation on a resin.
