taurodontism

tau·ro·don·tism

(taw'rō-don'tizm), [MIM*272700]
A developmental anomaly involving molar teeth in which the bifurcation or trifurcation of the roots is very near the apex, resulting in an abnormally large and long pulp chamber with exceedingly short pulp canals.
[L. taurus, bull, + G. odous, tooth]

taurodontism

[tô′rō·don′tiz·əm]
Etymology: L, taurus, bull; Gk, odous, tooth
a variation in tooth form characterized by prism-shaped molars with large pulp spaces, resulting from branching of the root only in the middle (mesotaurodontism), or in the apical third or not at all (hypertaurodontism).

taurodontism (tôr´ōdon´tizəm),

n a tooth in which the pulp chamber is elongated and enlarged, and extends deeply into the region of the roots. A similar condition is seen in the teeth of cud-chewing animals.

Such abnormalities may include peg-shaped incisors, long thin-rooted teeth, malformed molars, microdontia, enamel hypoplasia, shallow cusps, taurodontism and partial anodontia [Levy, 1967].
The pulp chambers appear to be duplicated, and taurodontism (long pulp chambers and short roots) may be present.
Taurodontism In taurodontism the pulp chambers are enlarged in an apical direction and the bifurcation or trifurcation point of the molars is also displaced toward the apex.
This tooth and the P4 show no evidence of taurodontism or enamel hypoplasia.
Other taurodont molars of undoubted Pleistocene age are known from the site, and this feature can be compared with the high incidence of taurodontism - a condition of enlargement of the pulp cavity and coalescence of the roots of molar teeth - among Neanderthal permanent molars (but the characteristic is also present among modern populations).
It is interesting that taurodontism, characterized by an enlarged pulp chamber and an apically positioned furcation of molar teeth, is frequently associated with increase in tooth size [Hamner et al.

No ectodermal morphological characteristics such as taurodontism, invaginations, short or thin roots were seen in the dentitions in which the primary molars persisted.
