Definition

A thistle tube shape of the pulp chamber, meaning an enlarged coronal pulp chamber with narrow pulp canals giving a radiographic appearance of the shape of a thistle tube or a flame. It may occur isolated or associated with other dental anomalies and rare diseases such as dentinogenesis imperfecta, which should be assessed and coded separately. The diagnosis thistle tube shape pulp requires clinical and radiographic examinations. [from HPO]

Disease or Syndrome
Dentin dysplasia type II (DTDP2) is a defect of dentin formation in which the clinical appearance of the secondary teeth is normal, but the primary teeth may appear opalescent, similar to teeth affected by dentinogenesis imperfecta. The roots of the teeth are of normal shape and morphologic character. The pulp chambers and root canals of the anterior teeth and the premolars are shaped like thistle tubes because of the radicular extension of the pulp chamber. Most teeth show accumulations of pulp stones in these unusually shaped pulp chambers (summary by Kalk et al., 1998). Also see dentin dysplasia type I (DTDP1; 125400).
