牙周翻瓣术治疗重度慢性牙周炎临床疗效

目的评价牙周翻瓣术治疗重度慢性牙周炎的临床疗效。方法选取重度慢性牙周炎患者70例作为研究对象，所有患者行牙周基础治疗，牙周基础治疗后6w行牙周翻瓣术。分别于牙周基础治疗前、基础治疗后6w及牙周翻瓣术后3、6个月对患者进行牙周专业检查，记录探诊深度（PD）、临床附着水平（CAL）、出血指数（B1）并进行比较。结果牙周翻瓣术后3、6个月PD、BI、CAL与术前比较均有显著改善，差异有统计学意义（P〈O．05），术后3个月与6个月比较差异无统计学意义（P〉O．05）。结论牙周翻瓣术治疗重度慢性牙周炎有较好的临床疗效。

Clinical effect of periodontal flap surgery on the treatment of severe chronic periodontitis

Objective To evaluate the clinical effect of periodontal flap surgery in the treatment on severe chronic periodontitis. Methods 70 cases of severe chronic periodontitis patients were selected as the object of study. All patients underwent periodontal flap surgery after periodontal initial therapy and periodontal examination before periodontal initial therapy, 6 weeks after periodontal initial therapy, 3 months after periodontal flap surgery, and 6 months after periodontal flap surgery. Probing depth （PD）, clinical attach- ment level （CAL） and Mazza bleeding index （BI） were recorded. Results PD, BI, CAL in periodontal flap surgery three months, six months compared with preoperative were significantly improved, the difference was statistically significant （P 〈0.05）, after 3 months and 6 months the differences were not statistically significant （P 〈0.05）. Conclusion Periodontal flap surgery can achieve better clinical curative effect on the treatment of severe chronic periodontitis.
