ABSTRACT

The taurodontism is an alteration of tooth morphology with the coronal portion elongated on body at the expense of tooth root portion, which is longitudinally diminished, producing a flat apical migration of pulp in multirooted dental organs. The most affected organs are permanent molars. This alteration also usually occurs in the primary dentition. The diagnosis is usually verified radiographic or after tooth extraction. Male patient age nine that required attention to present temporary dental organ and Angle Class III molar is reported. Body evaluation: short neck, long stem, long limbs. Passive and immature behavior. The facial topographical assessment: biotype oval, concave profile, protrusive lower lip, prominent chin. The panoramic radiograph revealed four first permanent molars with enlarged pulp chambers at the expense of root canals and root shortening. Evaluation with cytogeneticist and geneticist was requested. The patient did not present numerical structural alterations and a normal 46, XY chromosome formula was reported, so the presence of the syndrome was discarded and can think of a Mendelian autosomal dominant disorder. The dentist plays a crucial role in the diagnosis and treatment of these patients. We conclude that taurodontism is an isolated feature that does not compromise the vitality and dental organ function. It is a variation of shape including the neurovascular bundle which may be associated with various syndromes.
