This retrospective cone-beam computed tomography study aimed to investigate the possible associations of apical periodontitis (AP) with missed/unmissed second mesiobuccal (MB2) canals. MB2 canals and AP were investigated in 257 endodontically treated and 673 untreated maxillary molars, and the former were analyzed regarding missed/unmissed MB2 canals. The chi-squared test and odds ratio (OR) were used for statistics. The prevalence of MB2 canals in maxillary first molars was higher than that in second molars (p = 0.001). MB2 canals were 1.751 times more common in males than in females (OR: 1.751; 95% CI: 1.334-2.297), with a significant difference in the 18-39 age groups (p = 0.005). The risk for AP was 5.5 times greater in endodontically treated maxillary molars with missed MB2 canals than in those with unmissed MB2 canals (p = 0.012) (OR: 5.5, 95% CI: 1.549-19.527). The findings of this study reveal that the likelihood of the MB2 canal is higher in the maxillary first molars of young adult males.
这项回顾性锥束计算机断层扫描研究旨在调查根尖周炎（AP）与未发现/发现的近中颊侧第二根管（MB2）之间可能存在的关联。在257颗接受牙髓治疗的上颌磨牙和673颗未治疗的上颌磨牙中对MB2根管和AP进行了研究，并对前者未发现/发现的MB2根管进行了分析。采用卡方检验和比值比（OR）进行统计学分析。上颌第一磨牙中MB2根管的患病率高于第二磨牙（p = 0.001）。MB2根管在男性中的发生率比女性高1.751倍（OR：1.751；95%可信区间：1.334 - 2.297），在18 - 39岁年龄组中有显著差异（p = 0.005）。在牙髓治疗的上颌磨牙中，未发现MB2根管的牙齿发生AP的风险比发现MB2根管的牙齿高5.5倍（p = 0.012）（OR：5.5，95%可信区间：1.549 - 19.527）。本研究结果表明，年轻成年男性上颌第一磨牙中MB2根管的可能性更高。
