title: Multiple traumatic injury to maxillary incisors in an adolescent female: treatment outcome with two years follow-up.
abstract: Number, type and severity of dental injuries per patient differ according to the patient's age and the cause of accident. The trauma group resulting from pedestrian-, bicycle-, and car-related injuries is usually dominated by multiple dental injuries, injuries to the supporting bone and soft-tissue injuries. This report describes a case of a 16.2-year-old female who suffered traumatic injuries to her permanent maxillary incisors after a car accident. Concussion of tooth 12, extrusive luxation of tooth 11, avulsion of tooth 21 and subluxation with complicated crown fracture of tooth 22 were observed at the emergency visit 75 minutes after the trauma. Tooth 21 was dry stored for 15 minutes, then in milk for 60 minutes. The treatment plan according to IADT guidelines was performed with the satisfaction of the dentists and the patient. After 1 year follow- up a replacement root resorption of tooth 21 was diagnosed; it was then considered severe at the time of the 2 year control visit. Educational programs are essential to optimize the treatment outcome both at the accident site and also at the dental office.
