摘要
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。
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 RCT- group. Analysed the rate of post - obturation pain after three days and the rate of success after one year. Resuits： 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.
