Full intrusion of a tooth after facial trauma.
We report two cases of fully intruded tooth after facial fracture in adults. In the first case, the lateral incisor was intruded into the nasal cavity and slipped into the pyriform sinus during operation. The second case involved full intrusion of a molar into the maxillary sinus, resulting in infection. The importance of a thorough intraoral examination for patients with facial trauma is emphasized. All missing teeth should be accounted for to ensure that they have not dislodged inside the body. When full intrusion of a tooth is suspected, facial computed tomography scan may provide assistance with definite diagnosis. If an incisor is completely intruded into the nasal cavity, removal through the floor of the nostril should be considered.
