Abstract

Endodontic success depends on accurate diagnosis, complete debridement of diseased pulp tissue, and adequate disinfection of the root canal system. It is essential to have a solid grasp of root canal variations. Inadequate knowledge of complex root canal configurations can lead to missed canals, failure to negotiate canal deviations, bifurcations, trifurcations, anastomoses, fins, and isthmuses, thereby complicating treatment. This case series focuses on the importance of diagnosis, radiographic interpretation, and treatment planning in managing maxillary first premolars and mandibular second premolars with aberrant canal anatomy.

摘要

牙髓治疗的成功取决于准确的诊断、对病变牙髓组织的彻底清创以及根管系统的充分消毒。扎实掌握根管变异情况至关重要。对复杂根管形态的了解不足可能导致遗漏根管、无法处理根管偏移、分叉、三根管、吻合、嵴和峡部，从而使治疗复杂化。本病例系列重点关注在处理具有异常根管解剖结构的上颌第一前磨牙和下颌第二前磨牙时诊断、影像学解读及治疗计划的重要性。
