摘　　要：目的探讨根管治疗中急症发生的相关因素。方法 286颗患牙随机分为3组:A组96颗患牙,按常规步骤行根管治疗。B组96颗患牙预备管后患者口服地塞米松。C组94颗患牙,初诊行根管预备,开放引流3d。记录各相关因素,比较EIAE发生率。结果 A组17.71%的患牙发生EIAE,根管预备出根尖孔的患牙EIAE发生率显著高于根管预备长度欠和恰的患牙,患者后牙EIAE发生率高于前牙,差异有统计学意义(P<0.05),患者的性别与年龄与发生率无明显关系,A组较B、C组EIAE发生率高,差异有统计学意义(P<0.05)。结论预备长度和牙位与EIAE发作有显著关系,药物等预防措施可能降低发生率。ObjectiveTo investigate the relevant factors of Endodontic in-terapointment emergencies in root canal therapy.Methods The 268 teeths with root canal therapy were divided into three groups at random.Cases in the group A were treated according to the routine procedures of root canal therapy.Cases in the group B took dexamethasone tablets after the instrumentation.Cases in the group C were prepared at the first visit and had been left open for three days.The incidences of EIAE were statistically analyzed.Results The EIAE incidence of group A was 17.71%.The overall instrumented teeth and posterior teeth were significantly higher than those of other teeth（P〈0.05）,EIAE were not significantly related to the gender and age（P〈0.05）.The EIAE incidences of group A was significantly higher than that of group B and C（P〈0.05）.Conclusion The occurrence of EIAE was significantly related to overinstrumentation and tooth location,Taking dexamethasone may relieve EIE.
