MAIA, Ana Carolina Del-Sarto Azevedo et al. Traction of permanent maxillary central incisor impacted by the presence of mesiodens: ca. RFO UPF []. 2015, 20, 1, pp. 93-100. ISSN 1413-4012.

Introduction: supernumerary teeth, as the name suggests, are those that develop in upper jawbones, in addition to the normal series. It is believed that the etiology is related to hyperactivity of the dental lamina, trauma or even heredity. These teeth can be found in any area of the dental arches, and their most common location is midline of the maxilla, where they are called mesiodens. The presence of supernumerary teeth may cause several local disorders, including delayed eruption or impaction of adjacent teeth, diastemas, crowding, rotations, ectopic eruptions, root reabsorption, and formation of cysts. Objective and case report: this study aims to report a clinical case of surgical removal of mesiodens diagnosed in a 10-year-old patient, which caused the impaction of a permanent incisor. Surgical removal of the supernumerary was performed and a button was immediately bonded to the crown of the impacted incisor so to allow its traction. The patient was followed until complete eruption of element 21 and its realignment in the arch. Final considerations: we conclude that strict routine examinations and the use - when recommended - of additional tests are essential for proper diagnostic and therapeutic approach when identifying the occurrence of mesiodens.
