Abstract：
Aim This study aimed to explore the morphology and complexity of mandibular anterior teeth in a Western Saudi Arabian sub-population using cone beam computed tomography (CBCT). Methodology CBCT scans from 818 patients were evaluated, and 3193 mandibular anterior teeth were analyzed for the number of roots, canal, canal configurations, separation level, bilateral symmetry, and gender associations. Results The results showed that all examined central and lateral incisors had a single root, and the majority exhibited a single canal. The prevalence of two canals in mandibular central and lateral incisors was 20.1% and 23.2%, respectively, resulting in an overall prevalence of 21.7% for two root canals in mandibular anterior teeth. The separation level of the two canals was predominantly located in the middle third of the root. Type I canal configuration was the most common, followed by type III. A high degree of bilateral symmetry in the number of canals and canal configurations was noted. Conclusion The findings contribute to the understanding of root canal anatomy in the Saudi population and provide valuable information for endodontic treatment planning.
摘要：
目的本研究旨在使用锥形束计算机断层扫描（CBCT）探讨沙特阿拉伯西部地区下颌前牙的形态和复杂性。方法对818例患者的CBCT扫描进行评估，并对3193颗下颌前牙进行了根数分析，运河,运河配置，分离水平,双边对称，和性别协会。结果所有检查的中切牙和侧切牙均为单根，大多数人展示了一条运河。下颌中切牙和侧切牙中两条运河的患病率分别为20.1％和23.2％，分别,导致下颌前牙中两个根管的总体患病率为21.7％。两条运河的分离水平主要位于根的中间三分之一。I型运河配置是最常见的，其次是III型。注意到运河数量和运河构型具有高度的双侧对称性。结论这些发现有助于了解沙特人群的根管解剖结构，并为牙髓治疗计划提供有价值的信息。
