根管治疗的结果评估是至关重要的，适当的情况下选择和治疗计划。然而，关于非手术根管治疗的结果的报告差异很大。在大量患者人群中进行的流行病学研究和长期随访可以为临床医生提供有用的工具，用于临床决策和牙齿预后评估。在这项研究中，对来自美国50个州的1，126，288名患者的1，462，936颗牙齿进行了为期8年的初步牙髓治疗的结果进行了评估。治疗由私人全科医生和参加Delta牙科保险计划的牙髓医生完成，该计划为美国约1400万人提供保险。总体而言，97%的牙齿保留在口腔8年后，初步非手术牙髓治疗。再治疗、根尖手术和拔牙等不良事件的合并发生率为3%，大多数发生在治疗完成后3年内。对拔牙的分析显示，85%的牙齿没有完全的牙冠覆盖。在所有测试的牙齿组中，发现覆盖和非覆盖牙齿之间存在显著差异（p < 0.001）。总之，初步非手术牙髓治疗似乎是一种可预测的手术，8年后牙齿保留的发生率很高。
Outcome assessment of endodontic treatment is critical for appropriate case selection and treatment planning. However, reports on outcomes of nonsurgical endodontic treatment vary considerably. Epidemiological studies done in a large patient population and over a long follow-up period can provide the clinician with useful tools for clinical decision-making and assessment of tooth prognosis. In this study, outcomes of initial endodontic treatment done in 1,462,936 teeth of 1,126,288 patients from 50 states across the USA was assessed over a period of 8 yr. Treatment was done by private general practitioners and endodontists participating in the Delta Dental Insurance plan that insures approximately 14 million individuals in the USA. Overall, 97% of teeth were retained in the oral cavity 8 yr after initial nonsurgical endodontic treatment. The combined incidence of untoward events such as retreatments, apical surgeries, and extractions was 3% and occurred mostly within 3 yr from completion of treatment. Analysis of the extracted teeth revealed that 85% had no full coronal coverage. A significant difference was found between covered and noncovered teeth for all tooth groups tested (p < 0.001). In conclusion, it appears that initial nonsurgical endodontic treatment is a predictable procedure with high incidence of tooth retention after 8 yr.
