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).

Additional unusual dental findings such as single-rooted funnel-shaped molars, reduced crown size, enamel hypoplasia, supernumerary teeth, dental fusion, taurodontism, abnormal occlusal anatomy with wide grooves, and atypical cusps have been reported in most previous cases of this syndrome.
In the present study, the prevalence of other anomalies (odontoma, fusion, dens invaginatus, talon cusp, taurodontism, macrodontia, dilaceration, ectopic eruption and microdontia) were observed more rare than other prevalence studies (4,7,10,17).
A correlation has been determined between the presence of denticles and the enamel pearls, taurodontism, dilaceratio and crooked roots [5].

Other abnormalities like alopecia, taurodontism, mental retardation, small genitals, premature aging, nutmeg liver, horseshoe kidneys, amyloidosis, and development of Hodgkin's disease and adenocarcinoma have also been reported, (12,16) but not observed in this patient.

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.
