前言：本研究的目的是比较牙髓科医师和其他提供者提供的不同牙型的初始非手术根管治疗的结果。方法：通过使用保险公司数据库，对487,476例首次非手术根管治疗进行了随访，从治疗时间到出现由当前牙科术语代码提示的再治疗、根尖手术或拔牙的不良事件。计算提供者类型和牙齿位置的人口统计数据。kaplan meier。计算了1年、5年和10年的生存估计。使用Cox比例风险模型计算提供者类型和牙齿位置的风险比。结果：1年生存率为98%，5年生存率为92%，10年生存率为86%。在提供者类型的基础上，5岁时臼齿和10岁时所有牙齿类型的存活率存在显著差异。发现的最大差异是牙髓医生治疗的磨牙10年存活率高出5%。在这10年的磨牙组中，当比较其他提供者与牙髓医生的成功率时，发现风险比为1.394。结论：这些研究结果表明，无论提供者类型如何，根管治疗后10年的存活率都很高。牙髓医生治疗10年后的磨牙存活率明显高于非牙髓医生。
Introduction: The objective of this study was to compare the outcomes of initial nonsurgical root canal therapy for different tooth types' provided by both endodontists and other providers. Methods: By using an insurance company database, 487,476 initial nonsurgical root canal therapy procedures were followed from the time of treatment to the presence of an untoward event indicated by Current Dental Terminology codes for retreatment, apical surgery, or extraction. Population demographics were computed for provider type and tooth location. Kaplan-Meier. survival estimates were calculated for 1, 5, and 10 years. Hazard ratios for provider type and tooth location were calculated by using the Cox proportional hazards model. Results: The survival of all teeth collectively was 98% at 1 year, 92% at 5 years, and 86% at 10 years. Significant differences in survival on the basis of provider type were noted for molars at 5 years and for all tooth types at 10 years. The greatest difference discovered was 5% higher survival rate at 10 years for molars treated by endodontists. A hazard ratio of 1.394 was found when comparing other providers' success with that of endodontists within this 10-year molar group. Conclusions: These findings show that survival rates of endodontically treated teeth are high at 10 years after treatment regardless of provider type. Molars treated by endodontists after 10 years have significantly higher survival rates than molars treated by non-endodontists.
