目的对感染根管进行一次或多次性根管治疗，观察分析其术后疼痛及根尖周愈合情况，评价一次性根管治疗的临床应用。方法选取80例慢性根尖周炎患牙，一次组一次治疗完成根管预备和根管充填，与多次疗程[疗程间Ca（OH）2根管封药]完成根管治疗的患牙进行临床效果比较。主要临床指标有术后1周疼痛率、术后X线片及根尖周愈合率。结果患者术后1周疼痛率一次组为37．5％，多次组为35．0％，二者间差异无统计学意义（ P＞0．05），术后中重度疼痛的发生率均为15．0％，差异无统计学意义（ P＞0．05）。术后6个月根尖周愈合率一次组为81．6％，多次组为80．6％，差异无统计学意义（ P＞0．05）。结论感染根管一次性根管治疗的术后疼痛及根尖周愈合率与多次疗程差异无统计学意义，具备常规开展的临床可行性。

Objective To conduct one-visit or multi-visit root canal treatment for infected root canals ,to observe and analyze the postoperative pain and the periapical healing status and to evaluate the clinical application of one -visit root canal therapy .Meth-ods 80 teeth diagnosed as chronic apical periodontitis were recruited .40 cases were included in one-visit root canal treatment group and the other 40 cases in multi-visit group with calcium hydroxide as an interapoinment medicament .Main clinical assessments in-cluded postoperative pain ,postoperative X ray and 6 months′periapical healing response .Results There there was no statistically significant difference between the groups regarding postoperative pain (one-visit group 37 .5% ,multi-visit 35 .0% ,P>0 .05) and 6 months′periapical healing response(one-visit group 81 .6% ,multi-visit 80 .6% ,P>0 .05) .Conclusion One-visit root canal treat-ment has the same clinical effect(postoperative pain and periapical healing ) as multi-visit on infected root canals and has the clinical feasibility of routine use .
