摘要
目的:运用锥形束CT(CBCT)对牙根钙化患者进行显微根管治疗,并对出现根管治疗诊间急症(EIAE)的影响因素及预后因素进行分析.方法:选取2020年2月至2023年2月苏州口腔医院收治的80例根管钙化患者,均行CBCT检查并进行显微根管治疗,根据CBCT检查结果,统计EIAE的发生率和1年后预后(漏填、欠填、根管偏移)情况,采用多元logistic回归分析发生EIAE的影响因素.结果:80例患者共100根钙化根管,EIAE发生率为8.75%.logistic回归分析结果显示,性别、治疗前疼痛、治疗前瘘道、根尖阴影及牙髓活力均是影响EIAE发生的因素(OR=2.217、1.249、1.405、1.320、1.835,P＜0.05);牙髓活力、治疗前瘘道、术前有无根尖暗影、根管充填长度、充填致密情况及冠渗漏均是影响显微根管治疗预后的因素(OR=1.256、1.425、1.237、1.225、1.280、1.267,P＜0.05).结论:在显微根管治疗中 CBCT影像能够更详细了解钙化根管形态并明确根管走向,有助于对患牙个体特征、制定治疗方案和加强预后评估与分析,提升治疗效果.
Abstract
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.
