Abstract

Background:  The success of endodontic treatment depends on the proper identification of all the canals, thorough chemo-mechanical preparation followed by three dimensional obturation with hermetic seal. Failure of any of these steps may occur due to unusual tooth morphology.1 Usually mandibular molars have two roots with three canals (mesiobucccal, mesiolingual & distal) but in few teeth, the number of roots and canals vary. A major anatomical variant of the two-rooted mandibular first molar is a tooth with an additional distolingual third root. The variation in the number of roots is called Radix Entomolaris.2 Proper angulations and interpretation of radiographs help to identify pulp chamber and root anatomy. Achieving the endodontic success in the presence of an RE requires knowledge about its prevalence, diagnosis, morphology, canal confi guration, and clinical approach.5 This article presents three case reports of mandibular first molars with extra roots.

Keywords: radix entomolaris, variations, extra roots.
