Abstract

Taurodontism is an abnormal morphological trait of tooth shape, which usually occurs in multi-rooted teeth. An enlarged pulp chamber and apical displacement of the pulpal floor are characteristics. Endodontic treatment ofa taurodont tooth may be very difficult because it requires special care in identifying and treatment of the complex root canal system. The endodontic treatment ofa taurodont maxillary first molar is presented.
