Case of the Week: Taurodontism on CBCT

This fun case of taurodontism involves all the maxillary and mandibular molars. This tooth anomaly is not one that I come across often so when I saw this awesome example I just had to share.

Taurodontism refresher = elongated body/pulp chamber with shortened roots and lack of constriction of the cemento-enamel junction (CEJ). If you have a bunch of time or are bored you can even classify it further into hypotaurodontism, mesotaurodontism or hypertaurodontism. This is done by calculating the crown-to-root ratio using the deepest aspect of the occlusal surface to the furcation and the furcation to the apices.

Hypotaurodontism1.1 to 1.29
Mesotaurodontism1.3 to 2.0
Hypertaurodontism2.0+

Side note on this breakdown. I have no idea how this would be relevant for anyone in a clinical setting but maybe there is someway that this is useful. If you have any idea how or actually like to know this in a clinical setting please feel free to share below.

And now onto the fun case I came across. Here are some 3D reconstructions along with a rotated sagittal view. There are also two videos – sagittal and coronal.
