前牙急性根尖周炎根管治疗一次法后并发症及疗效的临床观察

Clinical Observation of Complication and Curative Effect of One Time Root Canal Treatment for Acute Periapical Periodontitis in Anterior Teeth

目的探讨前牙急性根尖周炎患者应用根管治疗一次法是否优于多次治疗。方法随机将140例急性根尖周炎患者分为两组,每组70例,分别行根管一次法治疗和多次治疗。观察比较两组患者术后1 d和术后5 d并发症情况及术后1年临床和X线检查结果。结果一次性根管治疗术后1 d并发症显著高于多次疗法(P<0.05),术后5 d疗效显著好于多次疗法(P<0.05),术后1年两组间疗效无显著性差异(P>0.05)。结论对于前牙急性根尖周炎患者可选择一次性根管治疗和多次疗法,但应用一次性根管治疗应慎重。

Objective To explore if one time root canal therapy has a better effectiveness than conventional root canal therapy in treating acute periapical periodontitis of anterior teeth.Methods A total of 140 patients with acute periapical periodontitis of anterior teeth were randomly divided into two groups.Each group had 70 patients in it.They were treated respectively by one time root canal therapy and conventional root canal therapy.The complications were observed in the patients after one day＇s and five day＇s treatment.Their therapeutic effects were compared according to clinical symptoms and X-ray examination one year after treatment.Results The incidence of complication of one time root canal therapy was higher than that of conventional root canal therapy after one day＇s treatment（P〈0.05）.The therapeutic effect of one time root canal was better than that of conventional root canal therapy after five day＇s treatment,but the curative effects by both methods had no significant difference after one year（P〉0.05）.Conclusion Both of conventional root canal therapy and one time root canal therapy can be adopted in treating acute periapical periodontitis of anterior teeth.One time root canal therapy must be carefully employed.
