一次性根管治疗在慢性根尖周炎中的临床观察

目的:观察一次性根管治疗在慢性根尖周炎中的临床疗效.方法:选择患有慢性根尖周炎的单根管患牙180例,随机分成两组,一组采用一次性根管治疗,另一组采用多次性根管治疗,观察术后3d疼痛发生率,随访一年成功率.结果:一次性根管治疗组术后3天疼痛发生率高于多次性根管治疗组,且有统计学差异,一年后两组成功率无统计学差异.结论:在慢性根尖周炎一次性根管治疗中,只要我们熟悉患牙的解剖形态及变异,严格无菌操作,减少根尖周组织的理化及生理性刺激,就能避免术后疼痛的产生.

Clinical Observation of Single-visit Root Canal Treatment for Chronic Periapical Periodontitis

Objective:To observe the effect of single-visit root canal treatment(RCT)on teeth with chronic periapical periodontitis.Methods:There were one hundred and eighty teeth with chronic periapical periodontitis,which were randomly divided into two groups:single-visit RCT group and multiple-visit RCTgroup.Analysed the rate of post-obturation pain after three days and the rate of success after one year.Results:The rate of post-obturaion pain after three days in single-visit group was significantly higher than that in multiple-visit group.No statistical difference was observed in success rate of RCT between two groups,Conclusion:In order to prevent the post obturation pain after single-visit RCT for chronic periapical periodontitis,dentists must know the anatomy and variation of teeth,prepare root canal sterile,decrease the physical,chemical and biotic irritations.
