: Endodontically treated teeth (ETT) often have significant structural damage and require multiple reinforcing methods during the reconstruction process. The aim of this study was to evaluate the complication rates of ETT with and without a post. : The study investigated various clinical factors, including technical complications as well as biological complications. All patients who had previously received fixed dental prostheses (FDPs) were subjected to clinical and radiographical examinations during their follow-up visits. Clinical and radiographic assessments were performed to determine the cumulative survival rate, and life table survival analyses of FDPs in the presence of complications were performed. : A total of 287 ETT were evaluated in this study, in which 219 were placed in females and 68 in males, with an average follow-up time of 82.4 months. There were no significant differences between ETT with a post and ETT without a post regarding the complication rates. The complication rates of the FDPs without a post revealed a survival rate of 58% after 5 years, 44% after 10 years, and 29% after 15 years. On the other hand, the complication rates of the FDPs with a post revealed survival rates of 50%, 30%, and 21% after 5, 10, and 15 years, respectively. The Kaplan-Meier survival analysis showed no significant differences in the complication rates, regardless of the existing of the posts ( = 0.830). : ETT restored with FDPs with or without a post can show similar complication rates in a long-term evaluation. Furthermore, the types of final restoration may not have an effect on the complication rate with ETT.
根管治疗后的牙齿（ETT）通常有明显的结构损伤，在修复过程中需要多种加固方法。本研究的目的是评估有桩和无桩ETT的并发症发生率。：该研究调查了各种临床因素，包括技术并发症以及生物学并发症。所有先前接受过固定义齿（FDP）修复的患者在随访期间均接受了临床和影像学检查。进行临床和影像学评估以确定累积生存率，并对存在并发症的FDP进行生命表生存分析。：本研究共评估了287颗ETT，其中女性219颗，男性68颗，平均随访时间为82.4个月。有桩ETT和无桩ETT的并发症发生率无显著差异。无桩FDP的并发症发生率显示，5年后生存率为58%，10年后为44%，15年后为29%。另一方面，有桩FDP的并发症发生率显示，5年、10年和15年后的生存率分别为50%、30%和21%。Kaplan-Meier生存分析显示，无论是否有桩，并发症发生率均无显著差异（=0.830）。：长期评估中，有桩或无桩FDP修复的ETT并发症发生率可能相似。此外，最终修复类型可能对ETT的并发症发生率没有影响。
