Abstract :

Endodontic treatment is often challenged by complex root canal anatomy, including calcified canals, additional canals, severe curvatures, C-shaped systems, and anatomical variations that may compromise treatment predictability. Successful management of these cases requires more than technical skills; it relies on a structured understanding of anatomy, accurate diagnosis, appropriate case assessment, and careful clinical decision-making. This presentation will explore a systematic approach to navigating anatomical complexity, from preoperative assessment and three-dimensional imaging to access cavity design, canal negotiation, glide path preparation, shaping, irrigation, and obturation. Particular emphasis will be placed on the role of magnification, ultrasonics, CBCT, and contemporary nickel-titanium instrumentation in improving safety and treatment outcomes. Through a series of challenging clinical cases, practical strategies and decision-making principles will be presented to help clinicians anticipate anatomical difficulties, minimize procedural errors, and transform complex endodontic anatomy into predictable clinical outcomes.

Learning objectives :

• Apply a systematic approach to the diagnosis, assessment, and clinical management of challenging root canal anatomy.
• Integrate contemporary technologies and clinical strategies to improve treatment safety, efficiency, and predictability in anatomically complex cases.
• Develop effective decision-making strategies to anticipate anatomical challenges, minimize procedural errors, and achieve predictable endodontic outcomes.
