INTRODUCTION
The purpose of this retrospective longitudinal cohort study was to evaluate the outcome of nonsurgical root canal treatment (NSRCT), expressed as survival for both periapical health and retention of roots/teeth, as determined by clinical evaluation, periapical film/digital radiography (PFR/DPR), and cone-beam computed tomography (CBCT) over 10 years, to determine the prognostic factors that influenced successful treatment outcomes.
METHODS
A total of 132 teeth (208 roots) with vital pulp received NSRCT at a university clinic. Eighteen factors (preoperative, intraoperative, and postoperative) were documented from the dental records and radiographs. Periapical indices with scores ≥2 (PFR/DPR) and ≥1 (CBCT) indicated the presence of a periapical lesion. Data were analyzed using the Kaplan-Meier test and the Cox proportional hazards regression model (P < .05).
RESULTS
The estimated 10-year overall survival rates for periapical health of roots/teeth were 89.4%/88.6% with PFR, 89.4%/89.3% with DPR, and 72.6%/69.7% with CBCT; the survival rate for root/tooth retention was 90.4%/91.6%.
CONCLUSIONS
The long-term outcome of NSRCT expressed as survival for periapical health was different with each radiographic method. Approximately more than 90% of the roots/teeth were retained for up to 10 years. The prognostic factors for periapical health were the disinfection of gutta-percha, missed canals, age, treatment sessions, and density of root filling (voids); the age and presence of a post were for root/tooth retention.
简介
本回顾性纵向队列研究的目的是评估非手术根管治疗（NSRCT）的结果，以临床评估、根尖片/数字射线摄影（PFR/DPR）和锥形束 CT（CBCT）在 10 年内确定的根尖健康和保留根/牙的存活率来表示，并确定影响治疗结果的预后因素。
方法
在一所大学诊所，对有活力牙髓的 132 颗牙（208 个根）进行了 NSRCT。从病历和射线照片中记录了 18 个因素（术前、术中、术后）。根尖指数得分≥2（PFR/DPR）和≥1（CBCT）表示存在根尖病变。使用 Kaplan-Meier 检验和 Cox 比例风险回归模型（P<.05）进行数据分析。
结果
用 PFR 估计的 10 年根/牙的总体根尖健康存活率为 89.4%/88.6%，用 DPR 为 89.4%/89.3%，用 CBCT 为 72.6%/69.7%；根/牙保留率为 90.4%/91.6%。
结论
以根尖健康存活率表示的 NSRCT 的长期结果因每种射线照相方法而异。大约 90%以上的根/牙在 10 年内保留。根尖健康的预后因素是牙胶的消毒、遗漏的根管、年龄、治疗次数和根管充填密度（空隙）；年龄和桩的存在是根/牙保留的预后因素。
