On the assumption that the colour difference between attached gingiva and alveolar mucosa is accompanied by a temperature difference, twenty subjects with a high standard of oral health were studied. Five points on either side of the mucogingival junction were examined by means of a thermocouple probe. A mean difference amounting to about 2/3 degrees C was found between the surface temperatures of the two structures.
基于附着龈与牙槽黏膜之间的颜色差异伴随着温度差异这一假设，对20名口腔健康状况良好的受试者进行了研究。使用热电偶探头检查了膜龈联合两侧的五个点。发现这两种结构的表面温度平均相差约2/3摄氏度。
