This case report describes the management of developmental dental alterations in permanent dentition as a consequence of severe intrusive luxation in its predecessors in a child of 2 years. At 10 years of age, this patient was referred for consultation due to lack of permanent maxillary right central and lateral incisors. Radiographic examination revealed impaction of hypoplasic permanent maxillary central incisor, absence of the lateral incisor and compound odontoma in region of the permanent maxillary lateral incisor. The odontoma was surgically removed and unerupted central incisor was placed in orthodontic traction over a period of 8 months. The central incisor presented with abnormal shape and was restored with composite resin. Odontoma histologic analysis was carried out through Hematoxylin and Eosin coloration and Scanning Electron Microscopy. Cement and osteocement formations were found in soft tissue, as well as some irregularly distributed dentine islands of tooth-like structures, indicative of compound odontoma. We followed up this patient for 5 years and orthodontic management was successfully performed for correct alignment of the maxillary right central incisor impacted by compound odontoma.
