摘　　要：目的:探讨胶原蛋白海绵对拔牙创牙槽窝愈合过程的影响。方法:取健康雌性SD大鼠16只,首先建立大鼠拔牙模型,实验侧(右)牙槽窝内填入胶原蛋白海绵,对照侧(左)作空白处理。于拔牙术后1、2、4、8周处死大鼠,观察牙槽窝成骨情况,利用实时定量PCR检测实验侧与对照侧成骨相关基因表达变化。采用SPSS 19.0软件包进行统计学分析。结果:术后实验侧牙槽窝较对照侧愈合明显好,实验侧及对照侧组织中Osterix、Runx2及Vegf均有表达,实验侧组织相关基因在术后1、2、4、8周不同时间点的表达水平显著高于对照侧(P<0.05)。结论:胶原蛋白海绵填塞拔牙创牙槽窝可在一定程度上促进牙槽窝早期骨愈合,这一过程可能与胶原蛋白海绵调节成骨相关基因表达水平有关。PURPOSE:To investigate the effect of collagen sponge on early bone healing process of alveolar fossa after tooth extraction in rats.METHODS:A total of 16 healthy female SD rats were selected.Animal models with tooth extraction were established.The right alveolar fossa inserted with collagen sponge was as the experimental group,and the left alveolar fossa was as the control group with treatment.The rats were sacrificed 1,2,4 and 8 weeks after tooth extraction,and the osteogenesis of alveolar fossa was observed.Real-time quantitative PCR(qt-PCR)was used to detect the changes of osteogenesis related gene expression.SPSS 19.0 software package was used for statistical analysis.RESULTS:After surgery,alveolar cavity healing was significantly better in the experimental group than in the control group.Osterix,Runx2 and Vegf genes were expressed in the experimental group and the control group,and the expression levels of related genes in the experimental group were significantly higher than the control group 1,2,4 and 8 weeks after surgery(P<0.05).CONCLUSIONS:Collagen sponge could promote early alveolar bone healing,possibly related to the expression level of osteogenic genes regulated by collagen sponge.
