Abstract: Knowledge of both normal and abnormal anatomy of the root canal system can directly affect the outcome of the endodontic therapy. This paper describes the nonsurgical endodontic management of the rare anatomical configuration middle mesial canal in previously treated mandibular first molar. After coronal access, the gutta-percha was eliminated. In precise examination of groove between two mesial canals, the middle mesial orifice was revealed. All root canals prepared chemo mechanically and obturated. After 6 months follow up, the tooth was asymptomatic and functional and apical lesion was healed.
