A Case of Intrusion With Mesiodens: 30 Months Follow Up (A Case Report)

Intrusive luxation is a dental injury that causes damage to supporting structures and pulp of a tooth because of its dislocation into the alveolar bone. Mesiodens is the most common type of supernumerary tooth found in anterior maxilla. This report presents the case of a intruded immature permanent incisor and the treatment of a inverted mesiodens. A 7-year-old boy was referred to the clinic 1 day after trauma. After clinical and radiographic examinations, intrusive luxation of the immature left permanent incisor and a inverted mesiodens diagnosed between the roots of central incisors. The surgical removal of mesiodens was delayed in order not to interfere the reeruption of intruded incisor. The intruded incisor, with careful monitoring, were allowed to spontaneously re-erupt, tooth started to re-erupt spontaneously in a few months. No periapical and/or pulpal pathology was observed during following period, root development continued, pulp remained vital. It can be concluded that intruded immature permanent teeth can spontaneously re-erupt, conserve their vitality, and continue their root development without any surgical or orthodontic management. However, with respect to surgical removal of mesiodens, ideal timing of intervention – immediate or delayed intervention – remains to be a highly controversial issue.
