Middle Mesial Canal In Mandibular Second Molar

Abstract

The ideal goal of endodontic treatment, the complexity of the root canal systems, management difficulties because of presence of isthmuses and communications between the canals, use of standardized techniques and the possibility of overlooking the presence of extra canals, exploration with the aid of magnification and detection of an accessory canals and management are matters that form the subject of discussion. With the advent of magnification, either by loupes or microscope, the astute clinician must be aware of recent literature that states that the mandibular second molar has a 0.95%-15% chance of a fifth canal. The third mesial canal (Middle Mesial Canal) in mandibular second molars was located in the middle of the distance between the mesiobuccal and mesiolingual canals. This is a case report shows the unusual anatomy of the mandibular second molar with middle mesial canal. In conclusion, every attempt should be made to find and treat all root canals of a tooth.
