Abstract

Root canal architecture is complex; hence, understanding any deviation from the norm is essential to achieving the best possible treatment result. Mandibular molars are typically double-rooted with one or two distal and two mesial canals. Nonetheless, the majority of anatomical abnormalities in terms of root number and form, as well as canal count, are seen in mandibular first molars. The presence of a third root, either buccal or lingual, in addition to the two already present, is one of the morphological variations that exist. The distolingual location of a supernumerary root is the defining feature of radix entomolaris (RE). A deep and passionate perception of root and root canal architecture and configurations is necessary to diagnose, identify, and treat these abnormalities, all of which can improve results. The endodontic management of a permanent mandibular first molar with a RE is covered in this case report. An explanation of the frequency, external morphological variations, and internal anatomy of the RE is presented.
