Taurodontism was hitherto considered to be a marker of oro-facial disorders. Since then, it has been reported with a moderately high-to-high prevalence on panoramic radiographs in case series of otherwise normal individuals in Brazilian, Middle Eastern and East Asian communities. This now understood higher than-formerly expected prevalence is important to the endodontist, orthodontist and restorative dentist. Therefore, the oral and maxillofacial radiologists should be aware of this phenomenon and its measurements to advise better their clinical colleagues.
