Non-surgical endodontic treatment of a Mandibular first premolar with three roots: A case report

The main aim of this report is to highlight the effective endodontic management of a mandibular premolar with varied canal configuration. The present case highlights the necessity of endodontic microscopes and knowledge on additional canals for exploring canal orifices and complex internal anatomy for better treatment planning and outcome of the therapy. In the present case, preoperative radiograph using digital radiography of the mandibular first premolar revealed three roots. The canal orifices were located using surgical microscope. One canal orifice was located on the lingual side and two canal orifices on the buccal aspect. All three canals had separate apical foramina. Obturation of all the three canals were done using lateral compaction technique.
