摘要
目的：评价一次法根管治疗术治疗慢性牙髓炎、根尖周炎的临床疗效。方法：选择160个慢性牙髓炎、根尖周炎的患牙。并随机分为二组，A组为一次法根管治疗组，B组为二次法根管治疗组。计算术后1天疼痛反应率和术后1年的治疗成功率，比较二种方法的临床疗效。结果：术后1天的疼痛发生率A组为17．5％，B组为12．5％，结果显示两组之间的差异无统计学意义（P〉0．05）。术后1年、A组随访成功75个，治疗成功率96％，B组随访成功76个，治疗成功率97．4％。两组之间的差异无统计学意义（P〉0．05）。结论：一次法根管治疗术的疼痛反应和治疗效果与二次法差异无显著性，可在临床推广应用。
Objective：To observe the clinical effect of single- Visit root canal therapy（RCT） on teeth with chronic pulpitis and apical periodontitis. Methods ： 160 teeth with chronic pulpitis and apical pefiodontitis were randomly divtded into two groups. Group A was the single - Visit root canal therapy. Group B was the two - Visit mot canal therapy. Pain reaction were recorded one day after operation and curative effects were evaluated one year after RCT. Rates of pain and success were calculated. Results：The rates of pain by one day after operation were 17.5% in group A and 12.5% in group B. The rates of success by one year after RCT were 96% in group A and 97.5% in group B. For rates of pain and success, there was. no significant difference between two groups after statistical analysis. Conclusion ：The was no difference on pain reaction and clinical effects between two methods. It is suitable for widespread adoption in single -visit root canal therapy.
