PUPO, José Artur Cunha et al. Orthodontic Extrusion of the Upper Central Incisor: A Rare Case of Pulp Mummification. Int. J. Odontostomat. [online]. 2013, vol.7, n.2, pp.241-244. ISSN 0718-381X.

Due to its anatomical positioning, the central upper incisors are the most affected teeth when related to trauma injuries in the craniofacial region, among with nose traumas. In childhood, traumatic injury is most often caused by bicycle accidents, sports, recreational activities or falls. The aim of this report is to describe a treatment for intrusion of the left maxillary central incisor and the subsequent complications in an 8-year-old boy. Also, the report emphasizes the importance of careful long-term follow-up monitoring intruded permanent teeth. Pulp tissue, as other tissues in the human body, tends to change with traumas. Some of those changes are natural while others occur as result of injuries to the dentin-pulp complex such as caries lesions, periodontal disease, calcifications, as in the present report, or restorative dental procedures. Normally conducted endodontic treatment must take place to obtain maximal results, but only after the re-stabilization of the tooth.

Keywords : orthodontic extrusion; pulp calcification; tooth movement; tooth avulsion.
