摘　　要：目的:分析牙髓病根管治疗患者根管预备中发生镍钛器械分离的影响因素。方法:回顾性分析2021年1月至2023年12月该院收治的120例牙髓病根管治疗患者的临床资料,统计牙髓病根管治疗患者根管预备中发生镍钛器械分离的情况,采用Logistic回归分析牙髓病根管治疗患者根管预备中发生镍钛器械分离的影响因素。结果:120例牙髓病根管治疗患者根管预备中,发生镍钛器械分离76例,占63.33%,设为发生组,其余44例设为未发生组。发生组患牙位置为磨牙、器械使用次数>10次、器械锥度4%、根管曲度>30°等占比均高于未发生组,差异有统计学意义(P<0.05);经Logistic回归分析结果显示,患牙位置为磨牙、器械使用次数>10次、器械锥度4%、根管曲度>30°等均为影响牙髓病根管治疗患者根管预备中发生镍钛器械分离的危险因素(OR>1,P<0.05)。结论:患牙位置为磨牙、器械使用次数>10次、器械锥度4%、根管曲度>30°等均为影响牙髓病根管治疗患者根管预备中发生镍钛器械分离的危险因素。Objective:To analyze influencing factors of nickel-titanium instrument separation in root canal preparation of patients with pulp disease undergoing root canal therapy.Methods:The clinical data of 120 patients with pulp disease undergoing root canal therapy admitted to this hospital from January 2021 to December 2023 were retrospectively analyzed.The nickel-titanium instrument separation during the root canal preparation in the patients with endodontic root canal treatment was statistically analyzed.Logistic regression analysis was used to analyze the influencing factors of nickel-titanium instrument separation in the root canal preparation of the patients with endodontic root canal treatment.Results:In the root canal preparation of the 120 patients with endodontic root canal treatment,76 cases of nickel-titanium instrument separation occurred,accounting for 63.33%,which was set as the occurrence group,and the remaining 44 cases were set as the non-occurrence group.The proportions of location of the affected tooth as the molar teeth,instrument use>10 times,instrument taper 4%,root canal curvature>30°in the occurrence group were higher than those in the non-occurrence group,and the differences were statistically significant(P<0.05).Logistic regression analysis showed that the location of the affected tooth as the molar teeth,the instrument use>10 times,the instrument taper 4%,the root canal curvature>30°are the risk factors affecting the nickel-titanium instrument separation in the root canal preparation of the patients with pulp disease undergoing root canal therapy(OR>1,P<0.05).Conclusions:The location of the affected tooth as the molar teeth,the instrument use>10 times,the instrument taper 4%,the root canal curvature>30°are the risk factors affecting the nickel-titanium instrument separation in the root canal preparation of the patients with pulp disease undergoing root canal therapy.
