目的分析一次性根充治疗有瘘型慢性根尖周炎的临床效果。方法选取2008年1月至2012年10月本院门诊就诊的658例有瘘型慢性根尖周炎患者,将906颗患牙随机分为对照组和治疗组,分别采用传统多次性根管治疗术和一次性根管治疗术,对比两组有效率。结果对照组310例共治愈241例,占77.7%,440颗患牙治愈400颗,总有效率为90.9%,治疗组348例共治愈316例,占90.8%,466颗患牙治愈460颗,总有效为98.7%,两组在治愈例数和总有效率对比差异均具有统计学意义(P<0.05)。结论一次性根充治疗术治疗有瘘型慢性根尖周炎明显优于传统多次性根管治疗术,值得推广使用。
Objective To analyze the clinical effect of one-time root pruning in treating chronic apical periodontitis with fistula. Methods From January 2008 to October 2012, 658 patients with chronic fovea-type chronic fovea with peripheral fistula were treated in our hospital. 906 teeth were randomly divided into control group and treatment group. Traditional multi-purpose root canal Treatment and one-time root canal therapy, the two groups were compared. Results In the control group, a total of 241 cases were cured in 310 cases, accounting for 77.7%. 440 teeth were cured and the total effective rate was 90.9%. In the treatment group, 348 cases were cured of 316 cases (90.8%), 466 teeth were cured, The total effective rate was 98.7%. There was a significant difference between the two groups in the number of cured cases and the total effective rate (P <0.05). Conclusion One-time root canal therapy for fistula chronic apical periodontitis is significantly better than the traditional multiple root canal therapy, it is worth promoting the use of.
