Traumatic intrusion of maxillary permanent incisors into the nasal cavity associated with a seizure disorder: report of a case.

Childhood traumatic dental injury is typically associated with motor vehicle accidents, sports, or other recreational activities. However, seizure disorders or other compromising medical conditions may precipitate dental trauma. Complete intrusion injuries in the mixed or permanent dentition are relatively rare. This paper describes the case history of an adolescent male who sustained displacement of a lateral incisor into the nasal cavity and complete bony intrusion of the three other permanent maxillary incisors because of a fall following a seizure. Counseling on helmet/face-shield usage for seizure-susceptible patients must be provided and documented, particularly after sustaining traumatic injury.
