Abstract

Background:  Most commonly permanent mandibular first molars have two roots, one mesial, and the other distal root. In permanent mandibular first molars, anatomical variations like the number of root canals configuration and presence of a number of roots and their morphology are most common. Most complex morphological variation is the presence of supernumerary root either lingually or buccally. When the supernumerary root is located distolingually to the main distal root is known as “Radix Entomolaris (RE)”. Adequate knowledge of root canal morphology and its variations are helpful for proper diagnosis, identification and treatment planning of this complexity, which leads to the successful outcome of endodontic treatment. The main goal of this article is to discuss the prevalence, morphology, classification, clinical and radiographic diagnosis and clinical significance of radix entomolaris in a permanent mandibular first molar.

Keywords: Distolingual root, radix entomolaris, mandibular molars, supernumerary root, additional root, extra root, root canal morphology.
