The diagnostic and treatment challenges associated with traumatized intruded permanent incisors: A case report

Intrusions are considered among the most severe forms of dental trauma and are associated with severe late complications. Usually general dental practitioners are the first to see and treat these children. The present case describes the challenges associated with the diagnosis and treatment of late complications of complete intruded maxillary incisors accompanied by profound buccal displacement in an 8-year-old patient. The treatments performed included root-canal treatment of right central incisor using mineral trioxide aggregate (MTA) and a combination of surgical and orthodontic repositioning of the intruded left incisor. Clinical and radiographic examinations at 2 years' follow-up revealed intact lamina dura and no sign of ankylosis in both incisors, apexogenesis of the right central incisor, and positive response to pulp testing of the left central incisor. The present report emphasizes the need to follow a child with severe dental injury and to consult with trained specialists when needed.
