Abstract

Objective: To investigate the effect of increasing the apical size of roots enlarged for root canal obturation on the outcome of non-surgical endodontic treatment for teeth with apical periodontitis.

Methods: In this retrospective study, we included 210 cases of single-rooted canals treated at our dental units between October 2009 and January 2022. The clinical outcomes of teeth with enlarged root apical size from the International Organization for Standardization standard numbers 25 to 100 were investigated.

Results: The number of teeth with a root apical size of ≤50 and ≥ 55 were 158 and 52, respectively. In the former case, 144 (68.6%) teeth had good prognoses and 14 (6.7%) had poor prognoses. In the latter case, 28 (13.3%) teeth had good prognoses and 24 (11.4%) had poor prognoses.

Conclusion: Unfavourable clinical outcomes were observed in root canal-filled teeth with an enlarged apical root size of ≥ 55. Thus, these sizes potentially indicate poor outcomes of nonsurgical endodontic treatments.

扩大根管封堵时的根尖尺寸会影响受根尖牙周炎影响的单根管牙齿的治疗效果

目的研究扩大根管封堵的根尖尺寸对根尖牙周炎牙齿非手术根管治疗效果的影响：在这项回顾性研究中，我们纳入了 2009 年 10 月至 2022 年 1 月期间在我院牙科治疗的 210 例单根根管治疗病例。调查了根尖尺寸扩大的牙齿（国际标准化组织标准编号为 25 至 100）的临床疗效：根尖尺寸≤50和≥55的牙齿数量分别为158和52颗。前者有 144 颗牙齿（68.6%）预后良好，14 颗牙齿（6.7%）预后不良。在后一种情况中，28 颗牙齿（13.3%）预后良好，24 颗牙齿（11.4%）预后不良：结论：根管充填的牙齿根尖扩大尺寸≥ 55 时，临床结果不佳。因此，这些尺寸可能预示着非手术根管治疗的不良后果。
