Dental injuries occurring from 1979–1985 in Finland in 6 contact team sports (American football, bandy, basketball, team handball, ice hockey and soccer) were studied. A total of 23,395 accidents occurred among registered players; 1526 (6.5%) of these accidents affected the dental structures. Contact between players caused over half of the accidents and a blow from a stick every third accident. Crown fractures were the most common type of dental injury, occurring most often to the maxillary central incisors. In most accidents (58.6%) only one tooth was affected. The highest rate of incidence was found in ice hockey (8.9%) and the lowest in American football (1.4%). The low incidence in American football was due to adequate facial and dental protection that is mandatory in this sport.
