Endodontic Retreatment of Mandibular Second Molar with Middle Mesial Canal: A Case Report

Elimination of microbes from ischolar_main canals and impeding of further reinfection is the objective behind an endodontic treatment. This is achieved by overall disinfection and shaping of canals which can then be filled using a three-dimensional filling with a fluid-tight seal. However, this process becomes complicated with the presence of additional ischolar_main canal systems. To achieve these goals, the clinician must have proper knowledge of regular anatomy and anatomic variants of ischolar_main canals. One such variant configuration in mandibular molars is the presence of a third canal in the mesial ischolar_main called middle-mesial canal. The purpose of the present article is to report successful non-surgical retreatment of a mandibular first molar with earlier missed Middle Mesial Canal.
