Middle Mesial Canals - A Review

Understanding the root canal morphology of the tooth as well as its variations is necessary for successful endodontic treatment as it helps in efficient root canal preparation and three dimensional obturation of the root canal system. However, complexity in the internal root canal anatomy imparts difficulties that can lead to failure of endodontic therapy. Mandibular molars often exhibit variations like middle mesial canal, C shaped canal, Radix entomolaris and Radix paramolaris. There are various ways to detect the canal variations like radiographs, endodontic explorer, special trougheningburs, ultrasonic tips, microscope, loupes, CBCT and so on. Recent advancements like cone-beam computed tomographyenables the clinician to understand the three-dimensional analysis of root canal morphology. This literature review gives a overview of middle mesial canal, its identification, identification, location, negotiation and obturation.
