Abstract

Objective: One key factor in determining endodontic treatment outcome is the clinicians' comprehension of tooth anatomy, as missed canals may harbor bacteria ultimately leading to apical periodontitis. The study aimed to investigate the prevalence of middle mesial canal (MMC) in Mandibular first molars (MFMs) of Saudi subpopulation.

Methods: The cross-sectional retrospective study was conducted at Qassim University Dental College from June to August 2023. Overall, 302 CBCT images with 604 bilateral lower first molars were examined by two calibrated assessors. The existence of MMC was noted. The data were coded, and analysis was done in SPPS-24. The reliability of inter-evaluator and intra-evaluator agreement for detecting MMC were estimated using Cohen's kappa.

Results: The patients' average age was 30.95±11.61years. The sample's female to male ratio was 1:1.75. The overall frequency of MMC was 14.2%. The differences in the frequency of MMC on the basis of gender, quadrants and age groups were found to be insignificant. Inter-evaluator and intra-evaluator reliability was noted to be 0.78 and 0.74, depicting acceptable reliability.

Conclusions: The MMC is an uncommon occurrence with rare bilateral presentation in MFMs of Saudi population. Endodontists performing endodontic treatment in such subjects should mindfully investigate inter mesiobuccal- mesiolingual canals area for locating, negotiating, and managing any present MMC's.

基于 CBCT 的沙特亚人群下颌第一磨牙中中槽频率调查。

目的：决定牙髓治疗结果的一个关键因素是临床医生对牙齿解剖结构的理解，因为漏掉的牙髓管可能会滋生细菌，最终导致根尖牙周炎。本研究旨在调查沙特亚群下颌第一磨牙（MFMs）中中轴管（MMC）的患病率：这项横断面回顾性研究于 2023 年 6 月至 8 月在卡西姆大学牙科学院进行。两名经过校准的评估人员共检查了 302 张 CBCT 图像和 604 颗双侧下第一磨牙。并指出是否存在 MMC。数据经编码后在 SPPS-24 中进行分析。采用科恩卡帕（Cohen's kappa）估算了评估者之间和评估者内部检测 MMC 的一致性可靠性：结果：患者的平均年龄为（30.95±11.61）岁。男女比例为 1:1.75。MMC总发生率为14.2%。不同性别、象限和年龄组的 MMC 发生率差异不明显。评估者之间和评估者内部的信度分别为 0.78 和 0.74，信度尚可接受：结论：在沙特人中，MMC是一种不常见的双侧MFM。牙髓科医生在对这类患者进行牙髓治疗时，应注意检查颊中-舌中管之间的区域，以便定位、协商和处理任何存在的MMC。

期刊介绍： It is a peer reviewed medical journal published regularly since 1984. It was previously known as quarterly "SPECIALIST" till December 31st 1999. It publishes original research articles, review articles, current practices, short communications & case reports. It attracts manuscripts not only from within Pakistan but also from over fifty countries from abroad. Copies of PJMS are sent to all the import medical libraries all over Pakistan and overseas particularly in South East Asia and Asia Pacific besides WHO EMRO Region countries. Eminent members of the medical profession at home and abroad regularly contribute their write-ups, manuscripts in our publications. We pursue an independent editorial policy, which allows an opportunity to the healthcare professionals to express their views without any fear or favour. That is why many opinion makers among the medical and pharmaceutical profession use this publication to communicate their viewpoint.
