This study assessed the ability of electronic thermography to identify internal derangement of the temporomandibular joint. The study population consisted of 30 patients with internal derangement verified by temporomandibular joint arthrotomography. Electronic thermography was conducted using an Agema 870 thermographic unit. Thermal assessments included: (1) pattern recognition; (2) pattern symmetry; (3) absolute temperature measurements; (4) delta T measurements; and (5) mean temperature measurements and differences within five designated anatomic zones. Results indicated: (1) low levels of thermal symmetry in patients with internal derangement of the temporomandibular joint, and (2) absolute temperature measurements and mean temperature zone measurements showing large delta T values (0.4 degrees C to 0.8 degrees C). Demonstration of characteristic thermal temporomandibular joint changes suggests that electronic thermography may have potential for assessing internal derangement of the temporomandibular joint. However, more extensive studies are needed before thermographic procedures can be accepted clinically.
本研究评估了电子热成像技术识别颞下颌关节内紊乱的能力。研究对象包括30例经颞下颌关节造影证实存在内紊乱的患者。使用阿杰玛870热成像仪进行电子热成像检查。热评估包括：（1）模式识别；（2）模式对称性；（3）绝对温度测量；（4）温差测量；以及（5）五个指定解剖区域内的平均温度测量及差异。结果表明：（1）颞下颌关节内紊乱患者的热对称性水平较低，（2）绝对温度测量和平均温度区域测量显示出较大的温差值（0.4摄氏度至0.8摄氏度）。颞下颌关节特征性热变化的显示表明，电子热成像技术可能具有评估颞下颌关节内紊乱的潜力。然而，在热成像程序被临床接受之前，还需要进行更广泛的研究。
