iRoot SP一次性根管治疗前牙窦道型慢性根尖周炎疗效观察

The effects of one-off root canal therapy using iRoot SP for chronic apical periodontitis with sinus in anterior teeth

目的:观察iRoot SP一次性根管治疗前牙窦道型慢性根尖周炎的临床疗效。方法:纳入240例前牙窦道型慢性根尖周炎患者,随机分成2组(n=120),在Nd:YAG激光消毒下,进行一次性根管充填:观察组采用iRoot SP以热牙胶连续波垂直加压技术充填根管,对照组采用AH-plus糊剂以热牙胶连续波垂直加压技术充填根管,观察术后48 h疼痛发生情况、术后10 d窦道愈合情况及1年后的疗效。结果:术后48 h观察组和对照组疼痛发生率分别为7.14%和15.0%(P=0.038);术后10 d,观察组和对照组窦道愈合情况有效率分别为95.8%和88.3%(P=0.031);术后1年复诊,2组疗效成功率分别为98.3%和94.8%(P>0.05)。结论:iRoot SP和AH-plus糊剂在一次性根管治疗前牙窦道型慢性根尖周炎中均取得良好疗效,但iRoot SP术后反应发生率低,窦道愈合快。

Objecive：To observe the clinical effects of one-off root canal therapy using iRoot SP in the treatment of chronic apical periodontitis with sinus in anterior teeth.Methods：240 anterior teeth of chronic apical periodontitis witn sinus were randomly divided into 2 groups（n=120）.One-off root canal filling were performed using iRoot SP（group A） and AH-plus（group B） respectively after Nd：YAG laser disinfection.Clinical effects were evaluated 48 h,10 days and 1 year after treatment.Results：In group A and B,the 48 h postoperative pain reaction rate was 7.14% and 15.0%（P〈0.05）,10 days postoperative effective rate was 95.8% and 88.3%（P〈0.05）,1 year after treatment the effective rate was 98.3% and 94.8%（P〉0.05） respectively.Conclusion：iRoot SP and AH-plus show reliable effect in the treatment of chronic apical periodontitis with sinus in anterior teeth with one-off root canal therapy.iRoot SP may result in sligher postoperative reaction and shorter healing time.
