摘　　要：目的:通过对根管治疗病例进行多因素综合分析,探讨根管治疗期间急症(EIAE)发生的主要原因及其预防方法。方法:收集159例根管治疗病例,对病人的年龄、性别、牙位、病因、治疗史、窦道、冲洗总药量、消毒药物、根充方法、根充情况和术后反应进行详细记录,对结果进行logistic回归分析。结果:通过回归分析选入的4个因素分别为根管冲洗总药量(P<0.01)、患牙是否为再治疗(P<0.05)、是否存在窦道(P<0.05)及根充情况(P<0.05),亦即上述4因素与EIAE的发生存在相关关系。年龄、性别、牙位、病因、消毒药物、根充方法(P>0.05)可能与EIAE的发生无相关关系。结论:足量的根管冲洗,初次治疗的患牙,存在窦道和恰当充填不易发生EIAE。AIM： To invtstige the causes and preventive means of endodontic interappointment emergencies （EIAE） by an analysis of the multi - factors. METHODS ： One hundred and fifty - nine cases involving root canal therapy were investigated through a study of the detailed records of the age, gender, tooth position, etiological factor, therapy history, fistula, rinsing quantity, root canal toxicidum, filling method, filling condition and the responses after root canal filling. Logistic regression analysis was used to process the data. RESULTS： Rinsing quantity used to wash root canal （ P 〈 0.01 ） , endodontic retreatments （ P 〈 0.05 ）, with or without fistula （ P 〈 0.05 ） and filling condition （ P 〈 0.05 ） were chosen by regression analysis. The four factors were related to the occurrence of EIAE. Other factors such as the age, gender, tooth position, etiological factor, root canal toxicidum and filling method might not be directly related to EIAE. CONCLUSION： Sufficient rinse solution used to wash root canals, tooth treated at the first time, existence of fistula and appropriate filling are effective in root canal therapy. These can prevent EIAE.
