A 2-year longitudinal study on signs and symptoms of mandibular dysfunction was performed with 285 17-year-old adolescents living in a certain geographic area in Skellefteå, Sweden. Crepitation was neither reported nor recorded in any subject. Both reports and recordings of TMJ clicking sounds fluctuated with time. The 2-year period prevalence was 24%, and 5.8% consistently reported TMJ clicking sounds. The corresponding figures for clinically recorded clickings were 36% and 9.3%, respectively. Both reported and recorded joint sounds were significantly more frequently found in 19-year-old girls than in boys. No consistent pattern of relationships between reported and recorded clicking sounds and single factors obtained by the questionnaire or clinically recorded variables could be found. Palpation tenderness in three muscle sites was to a varying degree related to both reports and recordings of clicking. Each year, significant relationships were found between reports of TMJ sounds and symptom indices. Recorded sounds were significantly related to a clinical index in the two oldest age groups. The prevalence of TMJ clicking sounds increases with age, and girls are more prone to have them than boys. In view of the natural longitudinal fluctuations, most clickings only need to be supervised, and when there is a demand for treatment, reversible methods are advocated in adolescents.
对瑞典谢莱夫特奥某一地理区域的285名17岁青少年进行了一项为期两年的下颌功能障碍体征和症状纵向研究。在任何受试者中均未报告或记录到摩擦音。颞下颌关节弹响的报告和记录均随时间波动。两年期间的患病率为24%，5.8%的人持续报告有颞下颌关节弹响。临床记录弹响的相应数字分别为36%和9.3%。报告和记录的关节弹响在19岁女孩中比在男孩中更常见。在报告和记录的弹响与问卷获得的单一因素或临床记录变量之间，未发现一致的关系模式。三个肌肉部位的触压痛在不同程度上与弹响的报告和记录有关。每年，颞下颌关节弹响的报告与症状指数之间均存在显著关系。在两个年龄最大的年龄组中，记录到的弹响与临床指数显著相关。颞下颌关节弹响的患病率随年龄增长而增加，女孩比男孩更容易出现弹响。鉴于自然的纵向波动，大多数弹响只需进行监测，当有治疗需求时，提倡在青少年中采用可逆方法。
