The study reports the total incidence as well as the incidence of different types of traumatic tooth injuries in a Swedish county in the age interval 0-19 years during 1989/90. The incidence of individuals experiencing tooth injuries was 13 per 1000 per year. Boys were more frequently injured in the age-groups 3-4 years and 7-9 years and girls, in the age-group 5-6 years. A method is presented defining uncomplicated and complicated tooth injuries as a basis for estimating the economic consequences of these injuries in the community. Boys more often suffered uncomplicated injuries to permanent teeth and girls, to primary teeth (p < 0.05). The same distribution was found for uncomplicated multiple tooth injuries. Boys sustained more uncomplicated hard tissue injuries and girls, more uncomplicated luxation injuries (p < 0.01). Using a classification according to the most serious tooth injury in each episode, 33% of the episodes had resulted in complicated injuries in which the pulpal tissue and/or periodontal membrane was severely damaged.
该研究报告了1989/90年期间瑞典一个县0至19岁年龄段不同类型创伤性牙损伤的总发病率以及发病率。经历牙损伤的个体发病率为每年每1000人中有13人。在3至4岁和7至9岁年龄组中男孩受伤更为频繁，而在5至6岁年龄组中女孩受伤更为频繁。提出了一种方法，将简单和复杂牙损伤进行定义，以此作为估计这些损伤在社区中的经济后果的基础。男孩恒牙遭受简单损伤的情况更为常见，而女孩乳牙遭受简单损伤的情况更为常见（p<0.05）。简单的多牙损伤也呈现出相同的分布情况。男孩遭受的简单硬组织损伤更多，而女孩遭受的简单牙齿脱位损伤更多（p<0.01）。根据每次发作中最严重的牙损伤进行分类，33%的发作导致了复杂损伤，其中牙髓组织和/或牙周膜受到严重损伤。
