摘要：

目的    观察Bio-Oss骨粉或骨胶原植入较大根尖囊肿刮治术后骨腔的临床效果。方法    选择2008年2月至2009年2月在南阳市口腔医院牙周科就诊的直径超过2 cm的较大根尖囊肿患者43例（124颗患牙），随机分为植骨组（22例，68颗患牙）和对照组（21例，56颗患牙）。囊肿刮治术后植骨组骨腔植入Bio-Oss骨粉或骨胶原，对照组不植骨，观察两组病例术后6个月和12个月的临床疗效。结果    植骨组术后6个月的成功率（81.8%）明显高于对照组（47.6%），差异有统计学意义（χ2 = 5.53，P < 0.05）；两组术后12个月的成功率差异无统计学意义（χ2 = 2.20，P > 0.05）。结论    Bio-Oss骨粉或骨胶原能明显促进骨再生，缩短囊肿刮治术后骨腔的愈合时间。

Abstract:

Objective    To observe the clinical effect of apical curettage on the bone defect by filling Bio-Oss or collagen. Methods    The study included larger periapical cyst of the root apex shadow exceeding 2 cm from February 2008 to February 2009. For the experiment group，68 cases of apical curettage had been filled with Bio-Oss or collagen. For the control group，56 cases were apically curettaged without filling Bio-Oss or collagen. Observe two groups on bone defect healing situation for 6 months and 12 months. Results    Twelve months after therapy，the success rate of the experiment group（95.5%）was higher than that of the control group（81.0%）. At 6 months，the success rate of the experiment group（81.8%）was significantly higher than that of the control group（47.6%）. Conclusion    Bio-Oss can obviously promote bone regeneration，shorten the bone defect of healing time after apical curettage.
