The prevalence of dental injuries in the permanent dentition was studied in a population comprising 1635 Swedish school children aged 7-15 years. A retrospective study of dental injuries in the deciduous dentition was also carried out. A total of 483 (30%) children in the material had experienced dental injuries. Twelve per cent of the injuries had been sustained before the age of 7 years and 18 per cent after that age. The majority of injuries had occurred between the ages 3-10 years. In the permanent dentition, over 75 per cent of the injuries recorded had been sustained before the age of 11 years. Boys had a higher trauma frequency than girls, the sex ratio being 1.2:1 in the deciduous dentition and 1.6:1 in the permanent dentition. Thirty per cent of the injured deciduous teeth required some kind of treatment. The corresponding figure for the permanent dentition was 46 per cent.
对1635名7至15岁的瑞典学童组成的人群进行了恒牙列牙损伤患病率的研究。同时还对乳牙列牙损伤进行了回顾性研究。该样本中共有483名（30%）儿童经历过牙损伤。12%的损伤发生在7岁之前，18%发生在7岁之后。大多数损伤发生在3至10岁之间。在恒牙列中，记录的损伤中有超过75%发生在11岁之前。男孩的创伤发生率高于女孩，乳牙列中的性别比为1.2:1，恒牙列中的性别比为1.6:1。30%的受伤乳牙需要某种治疗。恒牙列的相应数字为46%。
