Abstract: A thorough and comprehensive knowledge of internal and external root canal morphology vastly contributes to the success of root canal therapy. Mandibular molars sometimes present with an additional root located distolingually known as radix entomolaris (RE), necessitating a sharp and alert approach from the clinician. Accurate diagnosis and careful application of clinical endodontic skill is important to facilitate the endodontic procedure and to avoid the missed canals in such teeth. This paper describes the diagnosis and endodontic treatment of three cases of mandibular molars with RE, a rare macrostructure.
