Thorough knowledge of internal and external root canal morphology contributes to the successful root canal treatment. Mandibular molars display considerable variations with regard to the number of roots and rootcanals. One such anatomical variation is the presence of an additional root located distolingually called radix entomolaris. This paper describes two case reports of mandibular first molar with supernumerary distolingual root and provides insight into its endodontic management with the aid of surgical operating microscope.
Clinicians should be aware of the variable root canal anatomy in the distal root ofmandibular first molars.
Use of magnification helps to identify and locate additional root canals.
