The taurodontism even taurodontism (from Greek  ταυρος tauros "bull" and Greek  ὀδούς odous "tooth") is a very rare malformation of the molars . It usually occurs in the permanent teeth. Sometimes there is an autosomal dominant inheritance .

The first description comes from D. Gorjanovic-Kramberger from 1908.

The term was coined by Arthur Keith in 1913 .

Occurrence

There is an association with amelogenesis imperfecta , ectodermal dysplasia and tricho-dento-osseous syndrome , otodental syndrome and other rare syndromes.

It has also been seen in Klinefelter syndrome , XXYY syndrome, and Down syndrome .

Clinical manifestations

This is an abnormal shape of the tooth with enlarged tooth pulp , displacement of the bifurcation towards the tip of the root, missing waist on the tooth neck due to a malformation of the Hertwig epithelial sheath .

classification

A division into

  • mild form (hypotaurodontism)
  • moderately pronounced form (mesotaurodontism)
  • pronounced shape (hypertaurodontism)

was proposed by C. Shaw in 1928.
