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2cm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。
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.
