Mandibular first molar with radix entomolaris: A case report

Anatomic variations of mandibular molars are documented in literature. Variations in the anatomy are not appreciated by a great number of general dental practitioners. One such variation is occurrence of radix entomolaris, a supernumerary root occurring on the disto-lingual aspect of mandibular molars. This anomaly is rarely known to occur in the Indian population. Literature has also shown that the knowledge about the variations in the distal root anatomy in mandibular molars is not commonly known. This case reports the occurrence of radix entomolaris in mandibular first molar with three roots and four root canals. The case report discusses the frequency of occurrence, diagnostic means and endodontic management of radix entomolaris.
