Taurodontism is a morphoanatomical change in the shape of a tooth, which usually occurs
in multirooted teeth. An enlarged body and pulp chamber, as well as apical displacement of
the pulpal floor, are characteristic features. Endodontic treatment of a taurodont tooth is
challenging, because it requires special care in handling and identifying the number of root
canals. A case of endodontic treatment of a maxillary first molar with taurodontism is
presented.
