Permanent mandibular first molars usually have two roots with three root canals. However, the number of roots and canals may vary. The variation in the number of roots is called Radix. The presence of an additional third root or a supernumerary root located distolingually is known as Radix entomolaris and if present buccally, it is called Radix paramolaris. The occurrence of Radix paramolaris is less frequent compared to Radix entomolaris and is considered rare in Indian population. Awareness and understanding of this aberrant third root and its canal morphology can minimize the chances of a missed canal which in turn will contribute to the successful outcome of root canal treatment. This article reports successful endodontic treatment of a rare case of permanent mandibular first molar with Radix paramolaris in Indian population.
