Influencing factors and prognosis analysis of occurring EIAEs during diagnosis and treatment by using CBCT to conduct root canal treatment of micro-calcification
Objective:To use cone-beam computed tomography(CBCT)to conduct microscopic root canal therapy of micro-calcification and to analyze the influencing and prognostic factors of occurring endodontic inter appointment emergencies(EIAE)during root canal treatment.Methods:A total of 80 patients with root canal calcification who admitted to Suzhou Stomatological Hospital from February 2020 to February 2023 were selected,all of whom underwent CBCT examination and microscopic root canal therapy of micro-calcification.Based on the results of CBCT examination,the incidence of EIAE during root canal treatment and the prognosis post one year(missed filling,under filling,displacement of root canal)were analyzed by using statistical method.Multiple logistic regression analysis was used to analyze the influencing factors of occurring EIAE.Results:80 patients had a total of 100 calcified root canals,and the EIAEs incidence was 8.75%.The results of logistic regression analysis showed that gender,pre-treatment pain,pre-treatment fistula,apical shadow and vitality of dental pulp were all factors affecting the occurrence of EIAEs(OR=2.217,1.249,1.405,1.320,1.835,P＜0.05),respectively.The vitality of dental pulp,pre-treatment fistula,preoperative presence or absence of apical shadow,filling length of root canal,filling density and crown leakage were all factors affecting the prognosis of micro root canal treatment(OR=1.256,1.425,1.237,1.225,1.280,1.267,P＜0.05),respectively.Conclusion:In the microscopic root canal therapy,CBCT imaging can have a more detailed understanding of the morphology of calcified root canal and can clarify the direction of the root canal,which can help the individual characteristics of the affected teeth,and can contribute to formulate treatment plans,and strengthen the evaluation and analysis of prognosis,and improve the treatment effect.
