Curved paths: A comprehensive review and case insights into root canal anatomy

Endodontic therapy conserves the natural tooth by treating diseased pulp and promoting periapical healing. Curved root canals pose challenges in transportation, ledges, perforations, and instrument separation, impacting treatment results. Effective assessment and management are essential. Methodologies such as Schneider's and Weine's techniques, along with cone-beam computed tomography, refine the accuracy of curvature measurements. Proper techniques, involving anti-curvature filling and tactile controlled activation, are pivotal for successful treatment. Understanding root canal curvature and employing applicable approaches are vital for minimizing the complications and refining treatment success. An acclimatized approach grounded on curvature characteristics enhances endodontic sequels. This article reviews the cases involving patients with curved root canals, emphasizing treatment avenues and outcomes.
