Abstract

In-depth knowledge of the anatomical structure of the root canal system is fundamental for successful endodontic treatment. This research aimed to evaluate the root canal structures of lower premolars in the Saudi western demographic via Cone Beam Computed Tomography (CBCT) scans. 760 CBCT scans were reviewed, which incorporated 2747 mandibular premolar teeth. SPSS was employed for descriptive statistics and Pearson chi-square tests. The Kappa tests were executed for intra- and inter-observer consistency. The number of roots, canals, and canal configurations based on Vertucci's classification were assessed. The study further explored the prevalence, patterns, and variations of the root canal systems, considering gender-based variations and bilateral resemblance. Predominantly, mandibular premolars possessed a single root, though a minority displayed two or three roots. The occurrence of multiple canals was also on the lower side, with the type I canal pattern emerging predominantly. Gender-based distinctions were evident, as males exhibited a higher frequency of two-rooted premolars and multiple canals than females. It was noted that the anatomical differences were more in the mandibular first premolars than in the second premolars. A significant bilateral consistency was observed, with most teeth showcasing consistent root and canal numbers. This research offers essential perspectives on the diverse nature and variability of root canal anatomy within the Saudi Western cohort, facilitating better understanding and treatment planning in endodontics.

沙特人下颌前磨牙根管形态的三维评价:CBCT研究。
深入了解根管系统的解剖结构是根管治疗成功的基础。本研究旨在通过锥形束计算机断层扫描(CBCT)评估沙特西部人口的下前磨牙根管结构。回顾了760个CBCT扫描,其中包括2747个下颌前磨牙。采用SPSS进行描述性统计和Pearson卡方检验。卡帕测试执行内部和内部观察者的一致性。根据Vertucci分类对根数、根管数量和根管形态进行评估。该研究进一步探讨了根管系统的患病率、模式和变化,考虑了基于性别的差异和双边相似性。多数情况下,下颌前磨牙有一个根,虽然少数有两个或三个根。下侧多根管出现,以I型管型为主。性别差异明显,男性出现双根前磨牙和多根管的频率高于女性。结果表明,下颌第一前磨牙的解剖差异大于第二前磨牙。观察到显著的双侧一致性,大多数牙齿显示一致的根和管数。本研究为沙特西方人群根管解剖学的多样性和可变性提供了重要的视角,促进了对牙髓学的更好理解和治疗计划。

期刊介绍: Libyan Journal of Medicine (LJM) is a peer-reviewed, Open Access, international medical journal aiming to promote heath and health education by publishing high-quality medical research in the different disciplines of medicine. LJM was founded in 2006 by a group of enthusiastic Libyan medical scientists who looked at the contribution of Libyan publications to the international medical literature and saw that a publication outlet was missing. To fill this gap they launched LJM as a tool for transferring current medical knowledge to and from colleagues in developing countries, particularly African countries, as well as internationally.The journal is still led by a group of Libyan physicians inside and outside Libya, but it also enjoys support and recognition from the international medical community.
