Radix Entomolaris-Case Series

The success of root canal treatment depends on the accurate detection of all the canals, thorough an appropriately designed access cavity. Failure of the following steps in root canal treatment such as chemomechanical preparation and obturation may occur due to unusual tooth morphology. Therefore, understanding the various unusual anatomical representations is of prime importance. Frequently, mandibular molars have two roots with three canals (distal, mesiobuccal and mesiolingual) but in few teeth, the number of roots as well as root canals vary. This variation in the number of roots is known as radix. This article presents five case reports of mandibular first molars with extra roots and its management.
