目的探讨一次性根充治疗有瘘型慢性根尖周炎的临床疗效。方法选取2008年5月至2010年2月来我院门诊就诊的有瘘型慢性根尖周炎患者186例,256颗有瘘型慢性根尖周炎患牙,随机分为治疗组132颗患牙,行一次性根管治疗术;对照组124颗患牙,行传统多次性根管治疗术;对两组进行疗效对比。结果两组患者临床疗效比较,治疗组共治愈117例,占88.6,总有效率98.5,对照组共治愈96例,占77.4,总有效率98.5,两组患者治愈率及总有效率相比差异均有统计学意义,治疗组疗效显著优于对照组,P<0.05。结论一次性根充治疗术治疗有瘘型慢性根尖周炎疗效优于传统多次性根管治疗术,且患者复诊次数少,疗程短、省时及医疗费用低,疗效好,值得在临床推广使用。
Objective To investigate the clinical curative effect of one-time root-filling on chronic foveolar infection with fistula. Methods Totally 186 patients with fovea chronic periarthritis who came to our hospital from May 2008 to February 2010 were enrolled and 256 patients with fovea chronic periapical periodontitis were randomly divided into treatment group Teeth, one-time root canal therapy; control group of 124 teeth, the traditional multi-root canal therapy; the efficacy of the two groups were compared. Results The clinical efficacy of the two groups were compared, 117 cases were cured, accounting for 88.6, the total effective rate was 98.5, the control group were 96 cases, accounting for 77.4, the total effective rate was 98.5. The cure rate and total effective rate of the two groups were significantly different All were statistically significant, the treatment group was significantly better than the control group, P <0.05. Conclusions One-time root canal therapy is superior to traditional multiple root canal therapy in treating chronic periapical fistula. The number of follow-up visits is small, the course of treatment is short, the time-saving and medical cost are low, and it is worthy of clinical promotion use.
