‘External Inflammatory Root Resorption’ (EIRR) is a pathological condition affecting the root portion of the tooth that can lead to tooth loss if not diagnosed and treated early and correctly. Calcium Hydroxide [Ca (OH)2] is an excellent intracanal medicament, which is used in cases of teeth with external root resorption and also used in pulp necrosis and peri-radicular lesions. Permanent mandibular first premolar has one single root and rarely found with an additional second root. ‘Taurodontism’ is an embryonic dental anomaly of the tooth relating to tooth morphology characterized by vertically enlarged pulp chambers, apical displacement of pulp floors and short roots. Occurrence of all these rare dental malformations and conditions is a rarity. Therefore, the aim of this clinical case report is to enlighten readers about successful non-surgical management of bifurcated and mesotaurodontic mandibular right first premolar associated with external root resorption.
