摘要
目的：探讨次氯酸钠联合橡皮障用于降低根管治疗期间急症（endodontic interappointment emergencies,EIAE）发生率的临床疗效。方法：按照入院前后顺序,将287例在口腔门诊进行根管治疗的牙髓炎、牙髓坏死、慢性根尖周炎患者随机分为3组,即试验组、对照1组和对照2组,试验组和对照1组上橡皮障,试验组用5.25%次氯酸钠＋0.9%氯化钠交替冲洗根管,对照1组和对照2组用3%过氧化氢＋0.9%氯化钠交替冲洗根管,7 d后复诊,由同一名口腔内科医师记录患者在约诊期间急症发生情况。结果：试验组与对照1组、对照2组EIAE的发生率分别为4%、15.6%、28.6%,经χ^2检验,3组间的差异均有统计学意义（P〈0.05）。结论：5.25%次氯酸钠冲洗液与橡皮障结合使用能有效降低EIAE发生率。
Objective To evaluate the effect of sodium hypochlorite and rubber dam in reducing incidence of endodontic interappointment emergencies（EIAE）.Methods According to the order of admission.287 cases of endodontitis,pulpnecrosis or chronic periapical periodontitis that needed root canal therapy were divided into an experiment group,No.1 control group and No.2 control group.After rubber dams applied,the experiment group had the root canals irrigated with 5.25% sodium and 0.9% normal saline,while the two control groups with 3% hydrogen peroxide and 0.9%normal saline.Return visit was carried out 7 days after.The incidence of EIAE during the treatment was recorded by a dentist.Results The incidence rates of the experiment group,No.l control group and No.2 control group were 4%,15.6% and 28.6% respectively,and χ~2 test proved there were significant differences between the three groups（P〈0.05）.Conclusion The combination of 5.25% sodium hypochlorite and rubber dam reduces the incidence rate of EIAE.
