For the success of endodontic treatment, it is very critical for a clinician to have thorough knowledge of root canal morphology. There are a number of cases in literature wherein unusual anatomy have been discovered in mandibular first molars. Although the most common configuration is two roots and three root canals, mandibular molars might have many different combinations. There have been fewer reports regarding three mesial canals, three distal canals in mandibular first molars. The possibility of additional root canals should be considered even in teeth with a low frequency of abnormal root canal anatomy. This paper describes exploring of the unexplored, unusual anatomy of three mesial canals and three distal canals in mandibular first molars.
