The mechanical mathematics model of system was built, and the computer numerical value simulation was carried out. Taking the rotation speed and damping as the furcation parameters and combining with Poincare sectional view, oscillogram, phase plane plot, locus of axle center, power spectrum graph and self correlative functional diagram, the kinetic status of system was analyzed.

建立了系统力学数学模型，进行计算机数值模拟，以转速和阻尼为分叉参数，结合Poincare截面图、波形图、相平面图、轴心轨迹图、功率谱图和自相关函数图，分析了系统的运动状态。

There is no doubt that bacteria are the main etiologic agents for periodontal disease. With the progression of periodontal destruction, the following syptoms may occur: moderate to severe gingival inflammation, increased tooth mobility, pathological migration, vertical occlusal dimension loss, improper crown to root ratio, furcation involvement, absence of keratinized gingiva, unaesthetic appearance, as well as difficulties in chewing causing by unstable occlusion.

中文摘要细菌是牙周疾病的主要致病因素已是不争的事实，但随著牙周疾病破坏的进程，临床上表现出来的徵兆除了中度至重度不等的牙龈发炎现象之外，更可发现牙齿摇动度渐增、牙齿位移、咬合高度丧失、不良的牙冠根比、根叉病变、角化牙龈宽度不足、美观不佳、更甚者缺乏稳定的咬合导致咀嚼困难等。

Especially in the advanced localized periodontitis of molar with narrow furcation entrance diameter if un treated, the prognosis is poor, unless the oral hygieneis optimal in the furcal area.

一般而言，根叉齿槽骨病变患齿，尤其是带有狭窄根叉入口的进行性牙周炎之臼齿，如果根叉区域无法有效的牙菌斑控制或是没有治疗，则预后极差。

MTT assay was used to evaluate the cytotoxicity of β-TCP/col on the proliferation of PDLCs. PDLCs were cultured on β-TCP/col and observed by scanning electron microscope.β-TCP/col was implated into muscles of nude mice to observe tissue reactions by histologic methods.Ⅱ° furcation involvements models in beagle dogs were established, scaffold and and scaffold with cells and cytokines were implanted into defects. Histologic observation were conducted.

通过 MTT 法测定β-TCP/col 对犬 PDLCs 增殖的影响，在β-TCP/col 上复合培养犬 PDLCs 并进行电镜观察；将β-TCP/col 植入裸鼠肌袋内并进行组织学观察；建立比格犬Ⅱ°根分叉病变模型，分别植入材料、材料/细胞复合体或材料/细胞/细胞因子复合体，进行组织学观察。
