前牙慢性根尖周炎有瘘型一次性根管治疗疗效观察

目的:探讨前牙慢性根尖周炎有瘘型一次性根管治疗临床疗效.方法:慢性根尖周炎有瘘型前牙115例(患牙131颗),随机分为A、B两组.A组为一次性根管治疗术治疗组(63例72颗患牙),B组为传统多次性根管治疗术对照组(52例59颗患牙),分别于术后2年复查,进行临床疗效对照观察,所获资料作统计学处理.结果:A组远期治愈率93.06%(67/72颗牙).B组远期治愈率94.92%(56/59颗牙)(P＞0.05).结论:一次性根管治疗术治疗前牙慢性根尖周炎有痿型远期疗效与传统多次性根管治疗术元显著性差异,且省时、省钱,故优于传统多次根管治疗法.

Effect observation of one-off root canal treatment for chronic front teeth apical periodontitis with fistula.

Objective:To observe the curative effect of one-off root canal treatment for chronic front teeth apical periodontitis with fistula.Methods:131 front teeth from 115 cases with chronic apical periodontitis with fistula were randomly divided into two groups.Group A was the one-off root canal therapeutic that involved 72 teeth in 63 cases.Group B was the traditional many-time canal therapeutic as control group the involved 59 teeth in 52 cases.Two years later,these lesion teeth were performed examination and the cure effects between the two groups were compared.All data were managed statistically.Results:The long-term rates of cure were 93.06%(67/72 teeth) in Group A and 94.92%(56/59)in Group B(p>0.05).There were no significant difference in the cure effects between the two groups.Conclusions:One-off root canal therapeutic method not only has the same effect as the traditional method,but also has the advantage of saving time and expenses.Therefore,this method should be superior to the traditional method for treatment of chronic front teeth apical periodontitis with fistula.
