Abnormalities in the root canal anatomy are commonly occurring phenomenon. A thorough knowledge of the root canal anatomy and its variations is necessary for successful completion of the endodontic treatment. Mandibular Premolars are known for having an aberrant anatomy. Mandibular first Premolars have high flare-up and highest failure rates because of extreme variations in root canal morphology. The incidence of two roots in mandibular first premolar is quite rare (1.8%).This case report presents a relatively uncommon clinical case of mandibular first and second premolar with bifurcated roots. Careful interpretation of the preoperative radiograph, close clinical inspection of the floor of the chamber and proper modification of access opening are essential for a successful treatment outcome.
