Abstract: This study aims to present, through a literature review, the variations of C-shaped canals and treatment protocols for infected teeth. The literature review was developed using publications in English between 2015 and 2025. The results showed that C-shaped canals represent a complex anomaly of the internal morphology of teeth, predominantly found in lower second molars. Diagnosis by conventional radiographic methods is often insufficient, with identification often only being made after access to the pulp chamber. Treatment failure can occur due to the difficulty of completely sanitizing complex areas, such as isthmuses, and the inability to locate all extensions of the canal system, requiring in-depth knowledge of their anatomical variations and rigorous preoperative planning to achieve successful endodontic therapy. Cone beam computed tomography (CBCT) is essential for accurate diagnosis and three-dimensional visualization of these complex anatomies. In addition, the use of appropriate instrumentation and filling techniques that ensure complete sealing of the canal system, including the isthmuses, are crucial for disinfection and a favorable prognosis.
