Ahmed Dental College and Hospital, Kolkata, India Molars are frequently affected by caries among children and adolescents. An efficient endodontic intervention is crucial for their successful preservation in oral environment. Proper knowledge of the internal anatomy of a tooth is the stepping stones for successful treatment outcome in regular endodontic practice. Improper diagnosis with inaccurate treatment planning often result a failure in case of molars with extra roots leading to early tooth loss and development of inevitable functional, esthetic, and psychological problems. Though anatomical variation of tooth morphology is common, incidence of an extra lingual root distally in case of mandibular molars i.e. Radix entomolaris is relatively rare. In this article, two case reports of endodontic management of Radix entomolaris (RE) are presented. 8 25 2020 37 39 10.31254/dentistry.2020.5202 http://www.dentistryscience.com/IJDR_202052_02.pdf
