Radix entamolaris: An anatomical challenge

Abstract

Generally, mandibular first molars have one mesial and distal root but in few cases there are morphological variations where in the number of roots and root canals may vary. Radix Entomolaris (RE) is the presence of an additional lingual root distally in mandibular molars. Correct diagnosis is important before starting with endodontic therapy in these teeth to ensure successful treatment outcome. This case report series describes the endodontic management of mandibular first molar with radix entamolaris.
