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.
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.
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.
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.
探讨增加根管充填时扩大的根尖尺寸对根尖周炎患牙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月期间在我们牙科单位治疗的210例单根管病例。研究了国际标准化组织标准编号25至100的根尖尺寸扩大的牙齿的临床结果。
根尖尺寸≤50和≥55的牙齿数量分别为158颗和52颗。在前一种情况下，144颗（68.6%）牙齿预后良好，14颗（6.7%）预后不良。在后一种情况下，28颗（13.3%）牙齿预后良好，24颗（11.4%）预后不良。
根尖尺寸扩大至≥55的根管充填牙齿观察到不良临床结果。因此，这些尺寸可能表明非手术根管治疗效果不佳。
