摘　　要：目的观察一次性根管治疗术治疗老年人慢性根尖周炎的临床效果与可靠性。方法选取患有慢性根尖周炎的老年人106例，随机分为两组，实验组采用一次性根管治疗术，对照组用多次性根管治疗术，观察根管治疗术后1～7d疼痛发生率及根充后12个月成功率。结果患者术后疼痛率一次组为9．3％，多次组为11．5％，差异无统计学意义（P〉0．05）；1年后两组成功率分别为93．8％、91．8％，差异无统计学意义（P〉0．05）。结论在老年人慢性根尖周炎的治疗中，只要我们熟悉患牙的解剖形态及变异，遵守操作规程，严格无菌操作，一次性根管治疗术具有临床可行性。Objective To investigate the effect of single-visit root canal treatment （RCT） on teeth with chronic apical periodontitis using contemporary technique of canal cleaning, shaping and obturation in the aged. Methods There were 106 teeth with chronic apical periododntitis of the aged were randomly divided into two groups： single-visit RCT group and multiple-visit RCT group. The incidence of postoperative pain of the two groups were compared 1-7days after root canal obturation. 1 year fallow-up was performed using clinical and radiographic examinations. Results The incidence of post-obturation pain after 1-7 days was 9.3% in single-visit group and 11.5% in multiple-visit group. There was no difference between two groups. No statistical difference was observed in success rate of RCT between two groups. Conclusion In order to prevent the postobturation 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 irritation.
