摘要/Abstract

摘要：

目的　探讨根管治疗期间急症(EIE)的临床相关因素及防治方法。方法　544颗患牙分为3组:①常规治疗组　392颗患牙按常规步骤行根管治疗;②口服药物组　91颗患牙在根管预备后给予患者地塞米松口服,余同常规治疗组;③开放引流组　61颗患牙初诊时预备根管后开放引流2~3 d,余同常规治疗组。记录各相关因素,统计各组EIE发生率和急性发作指数(FUI)。比较各因素与EIE关系以及不同实验组EIE的差异。结果　常规治疗组中,19·1%的患牙发生EIE;根管预备超出根尖孔的患牙EIE发生率和FUI值均显著高于根管预备长度欠和恰的患牙;患者的年龄、性别及患牙的牙位、病变程度与EIE发生率无明显关系。口服药物组较常规治疗组FUI值显著降低。开放引流组与常规治疗组比较,其EIE发生率和FUI值均无显著差异。结论　操作因素与EIE发作有显著关系,药物等预防措施可能减少EIE发作。

Abstract:

Objective　To estimate the related factors and prophylactic measures of endodontic interappointment emergencies (EIE).Methods　The clinical caseswere divided intothree groups. Cases in the routine groupwere treated accordingtothe rou- tine procedures of root canal therapy. Cases in the medicament group took dexamethasone tablets after the instrumentation. Root canals in the drainage group were prepared at the first visit and had been left open for two or three days. The related factors were recorded. The incidences and flare-up index(FUI) value of EIE were statistically analyzed.Results　The EIE incidence of the routine group was 19·1%. The EIE incidence and FUI value of the overinstrumented teeth were significantly higher than those of other teeth(P<0·05). EIEwere not significantly related to the age, gender, tooth location and pathosis of the pulpal and peria- pical tissue(P>0·05). The FUI value of the medicament groupwas significantly lowerthan that of the routine group(P<0·05). Less severe EIE occurred in the cases of the drainage group than those of the control group(P>0·05).Conclusion　The occur- rence of EIE was significantly related to overinstrumentation. Taking dexamethasone may relieve EIE.
