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.
目的 本研究旨在使用锥形束计算机断层扫描（CBCT）探索沙特阿拉伯西部亚人群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，分析3193颗下颌前牙的牙根数量、根管、根管形态、分离水平、双侧对称性及性别相关性。结果 结果显示，所有检查的中切牙和侧切牙均为单根，且大多数为单根管。下颌中切牙和侧切牙双根管的患病率分别为20.1%和23.2%，下颌前牙双根管的总体患病率为21.7%。两根管的分离水平主要位于牙根的中三分之一处。I型根管形态最常见，其次是III型。观察到根管数量和根管形态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。
