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.

It also revealed taurodontism with molar teeth in the maxillary arch and underdeveloped mandibular ridge (Figure No.
Taurodontism is characterized by an enlarged pulp chamber with apical displacement of pulp floor and absence of cementoenamel junction constriction diagnosed by radiographic examination.
Abnormal tooth eruption, morbid root and coronal resorption, congenitally missing teeth, malocclusion, anterior open bites, pulpal calcification, dentin dysplasia, hypercementosis, root malformation, and taurodontism have been commonly seen.
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.
The frequency of other anomalies was as follows: molar-incisor hypomineralization 0.25%, turner hypoplasia 0.1%, fluorosis 0.1%, odontoma 0.1%, fusion 0.09%, gemination 0.06%, amelogenesis imperfecta 0.05%, dens invaginatus 0.03%, talon cusp 0.02%, taurodontism 0.02%, macrodontia 0.02%, dentinogenesis imperfecta 0.02%, dilaceration 0.02%, ectopic eruption 0.01% and microdontia 0.01%.
In addition, an association between taurodontism and hypodontia was found in a Dutch study, where taurodontism of the lower first molars was present in 29% of oligodontia patients but only 10% of controls [29].
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].
More recently, taurodontism of the first lower molar was detected in 24.8% of patients with congenital tooth loss, and first molar infraochlesis was detected in 65.7% of the same samples (Rubenstein et al., 1991; Bruce et al., 1994).
