Radix Entomolaris: An Endodontic Challenge

Variation of ischolar_main canal anatomy is always a challenge for accurate diagnosis and successful endodontic therapy. A thorough knowledge of most common anatomic characteristics and their possible variations is essential for the clinician. The hard tissue repository of the human dental pulp takes on numerous configurations and shapes. These aberrations occur so often that they can be considered as normal anatomy. Radix Entomolaris (RE) is one such aberration where an extra ischolar_main is present on the distolingual aspect of mandibular first molar (molar with 3 ischolar_mains). This article presents two case reports of mandibular first molars with extra ischolar_mains which was successfully treated.
