根管治疗期间急症发生情况的相关因素分析

Analysis of related factors of acute illness during root canal treatment

目的探讨影响根管治疗期间急症发生的相关因素。方法选取2018年1月至2019年1月来某院进行根管治疗的患者共500例。依据患者出现急症病情进行分组比较,采用单因素分析和多因素logistic回归分析患者在年龄、性别、牙位、窦道、冲洗总药量、消毒药物、根充方法、根充情况等差异以及诱导根管治疗期间急症发生的危险因素。结果500例患者中有168例患者发生急症,发生率为33.6%。单因素分析发现急症患者与非急症比较,在有无窦道、冲洗总药量、根充方法、根充情况方面存在差异(P<0.05),在年龄、性别、牙位、消毒药物方面无差异(P>0.05);多因素logistic回归分析发现无窦道、冲洗总药物2 mL及以下、多次根充及超充等是根管治疗期间急症发生的危险因素。概率ROC曲线下面积为0.917,提示该模型拟合优度很好。结论彻底清洁根管、提高填充质量,完善一次性根管治疗方法,可降低急症发生情况。

Objective To investigate the related factors affecting the occurrence of acute illness during root canal treatment.Methods Totally 500 patients who underwent root canal therapy in our hospital from January to January 2019 were enrolled.According to the patients′EIAE condition,Univariate analysis and multivariate logistic regression analysis were used to analyze differences in age,gender,tooth position,sinus tract,total flushing dose,disinfecting drug,root filling method,and root filling and the influencing factors inducing the occurrence of acute illness during root canal treatment.Results EIAE occurred in 168 of the 500 patients,with an incidence of 33.6%.Univariate analysis found that EIAE patients had differences in sinus tract,total flushing dose,root filling method,and root filling(P<0.05),compared with non-EIAE patients.There was no difference in age,gender,tooth position and disinfection drug(P>0.05).Multivariate logistic regression analysis showed that the risk factors of EIAE were:no sinus tract,2 mL of total drug washing and below,multiple root filling and overcharging.And the goodness of fit of this model indicated an outstanding fitting(AUC=0.917).Conclusion Thoroughly cleaning the root canal,improving the filling quality,and improving the disposable root canal treatment method can reduce the occurrence of EIAE.
