An epidemiologic sample of 84 subjects was followed longitudinally from the age of 15 to 25 years concerning clinical signs of craniomandibular dysfunction. There was an obvious fluctuation of the clinical signs of craniomandibular disorders over the 10-year period. No statistically significant change of any of the separate clinical signs or the clinical dysfunction index was noted, and no subject had severe signs of dysfunction. Muscle pain on palpation was still the most common clinical sign and was noted in nearly half of the subjects after 10 years. Temporomandibular joint clicking was common at the ages of 15 and 25 years, but no subject had developed locking of the temporomandibular joint during the 10-year period. Occlusal interferences in the retruded contact position and on the nonworking side increased during the 10-year period and were now present in 74% and 32% of the participants, respectively. A slight increase of occlusal wear was noted, but more pronounced wear was still a rare finding at the age of 25 years. Twenty-one subjects (25%) were judged by the examiners to be in need of some kind of functional treatment. The treatment advocated was in most cases minor, however, and could, with few exceptions, be incorporated in the subjects' ordinary dental treatment.
对84名受试者的流行病学样本进行了纵向跟踪，从15岁至25岁观察颅下颌功能紊乱的临床体征。在这10年期间，颅下颌疾病的临床体征有明显波动。未观察到任何单独临床体征或临床功能指数有统计学意义的变化，且没有受试者有严重的功能障碍体征。触诊时肌肉疼痛仍是最常见的临床体征，10年后近一半受试者出现该体征。颞下颌关节弹响在15岁和25岁时很常见，但在这10年期间没有受试者出现颞下颌关节绞锁。在10年期间，后退接触位和非工作侧的咬合干扰增加，现在分别有74%和32%的参与者存在。观察到咬合磨损略有增加，但在25岁时更明显的磨损仍然很少见。检查人员判断21名受试者（25%）需要某种功能治疗。然而，所提倡的治疗大多是轻微的，除少数例外，可纳入受试者的常规牙科治疗。
