Abstract :

The aim of this case report is to present the endodontic management ofC-shaped root canal system in mandibular first molar. A patient with root canal treatment initiated with right mandibular first molar was referred for further treatment. Radiograph revealed the presence of an unusual root canal morphology with the presence of a single conical root. The pulpal floor revealed normal mesiolingual orifice and semicolon groove that ran continuously from mesiobuccal orifice along the buccal wall to the distal canal orifice, suggestive of C-shaped canal anatomy which was confirmed with the aid of surgical loupes. Cleaning and shaping was carried out using rotary as well as hand files combined with passive ultrasonic irrigation with sodium hypochlorite. Obturation was done using combination of lateral compaction and thermoplasticized gutta-percha. Many reports deal with C-shaped root canal system, but very few describe its management in mandibular first molar, indicating a rare anatomical configuration.
