The mandibular molar is generally present with two roots of three canals, one being the mesial and other being the distal. Occasionally there is a third root present disto-lingually which is often referred to as “radix molar” or “radix entomolaris”. The present study reports about the clinical significance of a radix molar based on evidence reposts. This will further avoid any future complication in diagnosing and treating while addressing a patient's chief complaint
