Management of Radix Entromolaris: A Case Report

Abstract There are many causes of root canal failure, among them the most common cause is undiagnosed root canal. Mandibular molars typically have two roots mesial and distal. However, sometimes an additional root buccally (radix entomalris) or lingually (paramolaris) may be present. Awareness, diagnosis, and biomechanical preparation of additional canal is important for successful outcome of root canal therapy. This article presents successful management of mandibular first molar with radix entomolaris.
