Abstract

The records were analyzed of 106 patients with sports-related dental traumas treated in 1983 at the public oral surgery unit in Helsinki, Finnland; 51 were examined six years after injury. The mean age was 11.8 years (range 7-24 years). The woman/man ratio was 1:3. In 39 of cases, the injuries had arisen from ice hockey or skating; 30 happened during school hours; 80 were uncomplicated crown fractures, concussions or subluxations. During the six-year follow-up, of 80 teeth in 51 patients, root resorption was found in 6 teeth (7.5), periapical lesions were noted in 2 teeth (2.5), and obliteration of the pulp was seen in 4 teeth (5). Three teeth (3.7) had suffered loss of vitality. The pulp had been exstirpated in 13 of the traumatized teeth (16). In all, 13.7 of the patients were found to have complications six years later. The results showed that long follow-up periods are needed after dental injury. Verf.-Referat
