Abstract

Introduction: The study aimed to investigate the influence of various factors on the localization of the second mesiobuccal (MB2) canal in maxillary molars, a commonly missed canal during endodontic treatment.

Materials and methods: A comprehensive assessment of maxillary molars treated over three years with a dental operative microscope was conducted. Factors such as patient gender, age, tooth type, pulp status, pre-operative cone-beam computed tomography (CBCT), and treatment modality were examined. Statistical analyses included chi-square and multiple logistic regression.

Results: Among 333 treated maxillary molars, the MB2 canal was identified in 60.1%. The prevalence of MB2 canals was significantly higher in the first molars (72.3%) compared to the second molars (40.2%; P=0.001). Multiple logistic regression models showed that gender, tooth type, and treatment modality emerged as significant determinants of MB2 canal localization: males [odds ratio 3.01(CI 95%:1.71-5.32), P<0.001], first molar tooth [odds ratio 4.26 (CI 95%:2.53-7.18), P<0.001] and secondary endodontic treatment [odds ratio 0.06 (CI 95%: 0.004-0.890), P<0.04].

Conclusions: Patient gender, tooth type, and treatment modality play pivotal roles in the identification of the MB2 canal. Additionally, the availability of pre-operative CBCT imaging was associated with a heightened ability to locate the MB2 canal.

影响在上颌磨牙中找到第二根近颊根管的能力的变量。

引言：本研究旨在探讨各种因素对上颌磨牙近中颊第二根管（MB2）定位的影响，这是牙髓治疗中常见的缺失管。材料和方法：用牙科手术显微镜对治疗三年以上的上颌磨牙进行综合评价。检查了患者性别、年龄、牙齿类型、牙髓状态、术前锥束计算机断层扫描（CBCT）和治疗方式等因素。统计分析包括卡方和多元逻辑回归。结果：在333颗接受治疗的上颌磨牙中，MB2管占60.1%。第一磨牙的MB2管患病率（72.3%）明显高于第二磨牙（40.2%；P=0.001）。多元逻辑回归模型显示，和治疗方式成为MB2管定位的重要决定因素：男性[比值比3.01（CI 95%CI:1.71-5.32），PPP结论：患者性别、牙齿类型和治疗方式在MB2管的识别中起着关键作用。此外，术前CBCT成像的可用性与定位MB2管能力的提高有关。

期刊介绍： The Iranian Endodontic Journal (IEJ) is an international peer-reviewed biomedical publication, the aim of which is to provide a scientific medium of communication for researchers throughout the globe. IEJ aims to publish the highest quality articles, both clinical and scientific, on all aspects of Endodontics. The journal is an official Journal of the Iranian Center for Endodontic Research (ICER) and the Iranian Association of Endodontists (IAE). The Journal welcomes articles related to the scientific or applied aspects of endodontics e.g. original researches, systematic reviews, meta-analyses, review articles, clinical trials, case series/reports, hypotheses, letters to the editor, etc. From the beginning (i.e. since 2006), the IEJ was the first open access endodontic journal in the world, which gave readers free and instant access to published articles and enabling them faster discovery of the latest endodontic research.
