To improve the bonding treatment of vertically fractured roots, we aimed to the newly cementum formation on a compound of resin and dentin powder, which may improve the binding between resin and cementum. In vitro, cytotoxicity and Micro Tensile Bond Strength (MTBS) test were assessed. It had little cytotoxicity and exhibited higher bond strength. In vivo, in some cases, we observed the newly cementum formation on a compound of resin and dentin powder. This experiment might exhibit a possibility of the newly cementum formation on a resin.

为了改善垂直断裂牙根的粘接处理，我们在树脂和牙本质粉的复合材料上形成新的牙骨质，这可能会改善树脂与牙骨质的结合。体外进行细胞毒性和微拉伸结合强度（MTBS）试验。它具有较小的细胞毒性和较高的结合强度。在体内，我们观察到在树脂和牙本质粉末的混合物上形成新的牙骨质。这个实验可能展示了树脂上形成新牙骨质的可能性。
