Skin surface temperature (SST) measurements were carried out over the temporomandibular joint (TMJ) and masseter muscle (MM) of 159 healthy children and adolescents aged 7, 11, 15 and 18 years. No current symptoms were found of impaired general health or from the masticatory system or recurrent headache. The recordings were done with a thermocouple in contact with the skin. The mean SST over the TMJ and MM increased with age, and from the youngest to the oldest group regarding the TMJ by 1.3 degrees C (right) and 1.6 degrees C (left), and for MM by 2.1 degrees C (right) and 2.5 degrees C (left). Variation in the mean difference between sides of the TMJ was 0.0-0.2 degrees C and for the MM 0.1-0.3 degrees C. The variation in SST between sides was reduced with increasing age, but was higher for MM than for TMJ in all age groups. In the 7-years group, there was a significant difference between right and left SST over TMJ and MM. It is concluded that SST increases with growth during childhood and that the SST for the TMJ is higher than MM in all age groups. The finding of a high degree of thermal symmetry between sides in all age groups may have diagnostic potential for pathological conditions involving blood flow and in evaluation of treatment of these conditions.
对159名年龄分别为7岁、11岁、15岁和18岁的健康儿童及青少年的颞下颌关节（TMJ）和咬肌（MM）进行了皮肤表面温度（SST）测量。未发现目前存在一般健康受损、咀嚼系统问题或复发性头痛的症状。记录是通过与皮肤接触的热电偶进行的。TMJ和MM上的平均SST随年龄增长而升高，就TMJ而言，从最年轻组到最年长组，右侧升高1.3摄氏度，左侧升高1.6摄氏度；对于MM，右侧升高2.1摄氏度，左侧升高2.5摄氏度。TMJ两侧平均差值的变化为0.0 - 0.2摄氏度，MM为0.1 - 0.3摄氏度。两侧SST的变化随年龄增长而减小，但在所有年龄组中，MM的变化高于TMJ。在7岁组中，TMJ和MM的左右SST之间存在显著差异。得出的结论是，儿童期SST随生长而升高，且在所有年龄组中TMJ的SST均高于MM。所有年龄组两侧高度的热对称性这一发现可能对涉及血流的病理状况具有诊断潜力，并可用于评估这些状况的治疗效果。
