Signs of TMJ dysfunction syndrome were monitored longitudinally from the age of 12 to 14 years in 160 junior high students and 15 to 17 years in 480 senior high school students. Thirty-one percent of the junior high school students and 39.6% of the senior high school students presented with one or multiple signs of TMJ dysfunction syndrome at least once during the examination period. The percentage of subjects presenting continuously with one or multiple signs at all examinations was 8.9% among junior high school students and 12.9% among senior high school students. The predominant sign in the subjects, who continuously presented with one or multiple signs of TMJ dysfunction syndrome was TMJ sounds. The number of subjects presenting with TMJ clinical signs for the first time at the third examination (third year student) was high compared to the other examinations. When intra-individual longitudinal results were examined in subjects, who at least once during the examination period presented with one or multiple signs of TMJ dysfunction syndrome was found to be high (75.0% among junior high school students and 86.5% among senior high school students). In the subjects presenting with one or multiple signs of TMJ dysfunction syndrome continuously over the two year period, the percentage of subjects, who at least once presented with multiple signs was 90.9% among junior high school students and 22.0% among senior high school students.
对160名初中生从12岁至14岁、480名高中生从15岁至17岁纵向监测颞下颌关节功能紊乱综合征的体征。在检查期间，31%的初中生和39.6%的高中生至少有一次出现颞下颌关节功能紊乱综合征的一种或多种体征。在所有检查中持续出现一种或多种体征的受试者比例，初中生为8.9%，高中生为12.9%。持续出现颞下颌关节功能紊乱综合征一种或多种体征的受试者中，最主要的体征是颞下颌关节弹响。与其他检查相比，在第三次检查（三年级学生）时首次出现颞下颌关节临床体征的受试者数量较多。当对在检查期间至少有一次出现颞下颌关节功能紊乱综合征一种或多种体征的受试者进行个体内纵向结果检查时，发现该比例较高（初中生为75.0%，高中生为86.5%）。在连续两年出现颞下颌关节功能紊乱综合征一种或多种体征的受试者中，至少有一次出现多种体征的受试者比例，初中生为90.9%，高中生为22.0%。
