Today facial heat emission patterns may be rapidly obtained and quantified with the use of advanced electronic thermography units that have the promise of being a nonionizing, noninvasive, low-cost diagnostic alternative for the evaluation of temporomandibular joint disorders. This study design measured the use of electronic thermography as a tool to select between asymptomatic (control) subjects and a patient group with mild to moderate temporomandibular joint disorders. Study populations consisted of 24 asymptomatic (control) subjects and 20 patients with (1) either locked or unlocked temporomandibular joints, (2) varying degrees of limitation of mouth opening, (3) mild to moderate muscle pain, and (4) mild to moderate temporomandibular joint arthralgia. The results indicated that the control group demonstrated a high level of thermal symmetry over the temporomandibular joint region. The patient group demonstrated a low level of thermal symmetry with a delta T value of 0.4 degrees C. The control group was selected from the patient group with 85% sensitivity (17 of 20), and 92% specificity (22 of 24), and 89% overall accuracy (39 of 44), when selecting among the 44 subjects used in this study. The conclusion therefore is that electronic thermography shows promise as a method of diagnosing mild to moderate temporomandibular joint disorders.
如今，使用先进的电子热成像设备可以快速获取并量化面部热发射模式，这些设备有望成为一种用于评估颞下颌关节紊乱症的非电离、非侵入性且低成本的诊断方法。本研究设计测量了电子热成像作为一种工具，用于在无症状（对照）受试者和患有轻度至中度颞下颌关节紊乱症的患者组之间进行区分。研究人群包括24名无症状（对照）受试者和20名患者，这些患者患有（1）颞下颌关节锁定或未锁定，（2）不同程度的张口受限，（3）轻度至中度肌肉疼痛，以及（4）轻度至中度颞下颌关节疼痛。结果表明，对照组在颞下颌关节区域表现出高度的热对称性。患者组表现出较低的热对称性，温差值为0.4摄氏度。在本研究使用的44名受试者中进行选择时，对照组从患者组中挑选出来，其灵敏度为85%（20例中的17例），特异性为92%（24例中的22例），总体准确率为89%（44例中的39例）。因此，结论是电子热成像作为一种诊断轻度至中度颞下颌关节紊乱症的方法显示出前景。
