Bio-oss骨粉复合HIF-1α蛋白对拔牙创骨愈合影响的实验研究
|
Abstract:
摘要 目的:研究Bio-oss骨粉复合HIF-1α蛋白对拔牙创骨愈合的影响。方法:全麻下完整拔除3只Beagle犬的双侧下颌二、四前磨牙近中根,随机选择一个牙槽窝作为空白对照组,其余即刻分别植入bio-oss骨粉、bio-oss复合浓度为100 μg/L的HIF-1α蛋白,分别与术后6、12周取材,进行Micro-CT扫描、硬组织切片染色,观察拔牙创的骨愈合情况和组织病理学变化。结果:Micro-ct扫描显示,第6周时各组骨小梁数目、骨密度和BV/TV均有一定的差别。第12周时, bio-oss复合浓度HIF-1α组与bio-oss骨粉组、空白组差别显著(P<0.05),差别有统计学意义。硬组织切片显示第12周时,bio-oss复合HIF-1α组有良好的新骨形成。结论:Bio-oss骨粉复合HIF-1α蛋白骨修复材料可以促进拔牙创的愈合
