The incidence and type of dental injuries among Norwegian soccer players were assessed according to the files of the Norwegian Soccer Association. In 1979-83 a total of 7319 injuries were reported. Approximately 20% (1267) were dental injuries. In every fifth case the expenses for necessary dental treatment exceeded the maximum compensation from the insurance company. The majority of the injuries occurred among male players (96.5%). Also the relative frequency of dental injuries was higher in men than in women. The prevalence of dental injuries was highest in the top division, and decreased gradually down through the divisions. Goalkeepers seemed to be more susceptible to injuries than did the other players. Uncomplicated crown fracture of maxillary front teeth was common and accounted for 45% of all dental injuries.
