Taurodontism - case report of a morpho-anatomical variant

Taurodontism is an important abnormality in tooth morphology. Therefore, this anatomical disparity requires an understanding of the tooth morphology, which is essential for cavity preparation, root canal therapy and extraction. Metric analysis was carried out through categorisation, by means of intraoral periapical radiographs that were exposed using an extension cone paralleling (XCP) instrument (paralleling technique), and superimposed with a calibrated grid. This revealed hypertaurodont premolars in two patients and six hypertaurodont and two hypotaurodont molars in another patient. Keywords: bull-like teeth, endodontic therapy, XCP
