This study aims to report a retrospective observation of the prevalence of apical periodontitis (AP) and quality of root canal treatment in cone-beam computed tomography (CBCT) scans among the Mid-West Indian population.
A total of 1229 CBCT scans were obtained across different CBCT centers in western India. After the exclusion criteria, those that were included were divided into broadly two groups - those that were filled and those that were unfilled. Various parameters were taken into account such as AP, length of the root canal filled, and coronal filling.
There were a significantly higher percentage of nonfilled canals. Poor filling quality, inadequate coronal restoration, and also missed extra canal were significantly associated with AP. Both males and females showed higher presence of AP in the nonfilled teeth than filled ones (X2 - Chi square value M = 612.156, < 0.00001, X F = 1032.9092, < 0.00001).
(1) The inadequacy of the filling of the root length was a contributory factor to the higher prevalence of AP among the study population. (2) The density of the filling and the quality of the coronal filling also significantly affected the successful outcome of the root canal treatment.
本研究旨在对印度中西部人群锥形束计算机断层扫描（CBCT）中根尖周炎（AP）的患病率及根管治疗质量进行回顾性观察。
在印度西部不同的CBCT中心共获取了1229份CBCT扫描图像。根据排除标准筛选后，纳入的病例大致分为两组——已充填组和未充填组。考虑了各种参数，如根尖周炎、根管充填长度和冠部充填情况。
未充填根管的比例显著更高。充填质量差、冠部修复不充分以及遗漏额外根管与根尖周炎显著相关。男性和女性未充填牙齿的根尖周炎发生率均高于已充填牙齿（X2 - 卡方值M = 612.156，P < 0.00001，X F = 1032.9092，P < 0.00001）。
（1）根管长度充填不足是研究人群中根尖周炎患病率较高的一个促成因素。（2）充填密度和冠部充填质量也显著影响根管治疗的成功结果。
