To estimate the incidence of temporomandibular disorder (TMD) pain among Swedish adolescents by age and gender and to describe the temporal patterns of TMD pain.
This 3-year longitudinal study was carried out at all Public Dental Service clinics in a Swedish county from 2000 to 2003. All individuals aged 12 to 19 years in the county who visited the clinics for annual examinations were eligible for the study.
Overall, the incidence of TMD pain among all adolescents was 2.9% annually among 2,255 participating adolescents. Incidence among girls was significantly higher than in boys, 4.5% versus 1.3%, respectively. Incidence increased with age in girls and boys, although less so in boys (3.0% to 6.9% versus 1.7% to 2.6%). These adolescents were re-examined annually for 3 years, and a fluctuating pattern of TMD pain was common. Overall, 11.4% of all subjects reported TMD pain on at least 1 occasion; 88.6% of the cohort remained pain-free. Of those reporting TMD pain, 4.7% could be defined as intermittent cases, 3.1% were single-incident cases, 0.9% were recurrent cases, and 0.9% had continuing pain for 1 or 2 years.
The incidence of self-reported TMD pain among Swedish adolescents aged 12 to 19 years increased with age, particularly among girls. The pattern of pain in most adolescents fluctuated over time. Less than 1% of the cohort had continued pain over each year, and the majority of these subjects were girls.
按年龄和性别估算瑞典青少年颞下颌关节紊乱病（TMD）疼痛的发病率，并描述TMD疼痛的时间模式。
这项为期3年的纵向研究于2000年至2003年在瑞典一个县的所有公共牙科服务诊所开展。该县所有12至19岁到诊所进行年度检查的个体均符合研究条件。
总体而言，在2255名参与研究的青少年中，所有青少年每年TMD疼痛的发病率为2.9%。女孩的发病率显著高于男孩，分别为4.5%和1.3%。男孩和女孩的发病率均随年龄增加，尽管男孩增加幅度较小（分别为3.0%至6.9%和1.7%至2.6%）。这些青少年接受了为期3年的年度复查，TMD疼痛呈波动模式很常见。总体而言，11.4%的所有受试者至少有一次报告TMD疼痛；88.6%的队列无疼痛。在报告TMD疼痛的人中，4.7%可定义为间歇性病例，3.1%为单次发作病例，0.9%为复发性病例，0.9%持续疼痛1或2年。
12至19岁瑞典青少年中自我报告的TMD疼痛发病率随年龄增加，尤其是女孩。大多数青少年的疼痛模式随时间波动。每年不到1%的队列有持续疼痛，且这些受试者大多数是女孩。
