Taurodontism is a rare dental anomaly in which the involved tooth has an enlarged and elongated body and pulp chamber with apical displacement of the pulpal floor. It has a very low incidence and very few cases are reported in literature in deciduous dentition. Endodontic treatment of a taurodont tooth is challenging and requires special handling because of the proximity and apical displacement of the roots. In this article a case of five year child with bilateral involvement of mandibular second molars is presented.
