Mastering the art of endodontics requires a complete knowledge of morphology, principles of debridement and obturation. The failure in endodontic treatment has long been intriguing the Dental Surgeon because of insufficient knowledge of root canal system. Endodontic therapy in multi rooted teeth often pose a challenge to the endodontist because of wide variations in number and configuration of the root canals. Since the mandibular first molar is the tooth most frequently treated endodontically, and since the literature is so inconclusive and variable as regards morphology of this tooth, the present study was undertaken for a detailed investigation of the curvatures and configurations of the root, canals of permanent mandibular first molar. The variations are mostly detected in the mesial roots hence only mesial root of mandibular first molar was selected for this study. In order to evaluate configuration of the root canals, three dimensional radiographs were taken from buccolingual as well as mesiodistal direction.
