本研究的目的是研究β-磷酸三钙（β-TCP）的孔隙特性对犬III类根分叉缺损牙周愈合的影响。制备两种类型的β-TCP用于接枝; 1）内径为300 μ m的隧道管结构，和2）具有互连大孔的连续孔结构。30个下颌前磨牙的分叉处植入每种类型的β-TCP或不处理作为对照。术后8周处死犬，并对愈合进行组织学评价。隧道结构组连接上皮向下生长明显少于其他两组（p
The aim of this study was to investigate the effect of the pore characteristics of beta-tricalcium phosphate (beta-TCP) on periodontal healing in class III furcation defects in dogs. Two types of beta-TCP were prepared for grafting; 1) a tunnel pipe structure with an inner diameter of 300 mu m, and 2) continuous pore structure with interconnected macropores. The furcations of thirty mandibular premolar teeth were implanted with each type of beta-TCP or were left untreated as control. The dogs were sacrificed 8 weeks post-surgery, and healing was evaluated histologically. Downgrowth of junctional epithelium in the tunnel structure group was significantly less than that in the other two groups (p
