BORIE E, Eduardo; OPORTO V, Gonzalo  and  ARACENA R, Daniel. Dens evaginatus in Hemophilic Patient: A Case Report. Int. J. Morphol. [online]. 2010, vol.28, n.2, pp.375-378. ISSN 0717-9502.

Tooth development occurs through the interaction between oral tissues during embryogenesis. Alteration through odontogenesis may cause tooth morphological alterations, one of these could be Dens evaginatus. This anatomical variation could be originated from an abnormal proliferation and folding of a portion of the inner enamel epithelium and subjacent ectomesenchymal cells of the dental papilla into the stellate reticulum of the enamel organ during the bell stage of tooth formation. Dens evaginatus is defined as a tubercle, or supplemental solid elevation on some portion of the crown surface. Inadequate clinical management of these teeth may result in a pulpal exposure and possible loss of vitality of the tooth. The research wants to report a case of Dens evaginatusin a permanent mandibular premolar requiring endodontic treatment.A 13-year old male patient attended the Dental Service of a local Hospital, reporting pain the lower left side of the jaw. He reported to be in medical treatment for hemophilia. During an intra oral examination, the left side in the mandible exhibited a multitubercular appearance of left premolars which suggest. Patient shows a sinus tract related to tooth 3, 4, which was sore to palpation and percussion. In radiographic analysis a radio-opacity appeared in the tubercle area of the tooth. Due to low incidence of this anomaly among the young population, it is important that Dentistry related professionals know the characteristics of this anatomical variation in order to perform an adequate clinical management of Dens evaginatus.
