Temporomandibular dysfunction syndrome (TMD) is a common disease among dental patients. It occurs as a consequence of malfunction of the tempromandibular and/or surrounding facial muscles. LED red light therapy is not been well established, and it is important to find out the role of this technique in the treatment of temporomandibular disorders.
To evaluate the efficacy of the LED red light in the treatment of the tempromandibular dysfunction syndrome.
Fifty students of the College of Dentistry/University of Baghdad with myofacial pain associated with Tempromandibular Disorder volunteered to participate in this study and be evaluated during both treatment and follow-up periods. They were 40 (80%) females and 10 (20%) males. Patients were divided into 2 groups: Group A treated by TenDlite® Medical Device model 204 with a LED's of wavelength 660 nm (red light) and Group B given placebo (no treatment at all) by just putting the TenDlite device near the tender points without battery and turning ON the device.
The changes in the pain value and number of the tender muscles in both groups were highly significant, only placebo group less but with no significant differences.
This study showed that red LED therapy could be useful in improving patient's symptoms regarding pain, clicking, and number of tender muscles. In addition, this study showed the importance of the psychological part of treatment of those patients. This trial is registered with TCTR20190406002.
颞下颌关节紊乱综合征（TMD）是牙科患者中的常见疾病。它是颞下颌关节和/或周围面部肌肉功能障碍的结果。LED红光疗法尚未得到充分证实，因此弄清楚该技术在颞下颌关节紊乱治疗中的作用很重要。
评估LED红光治疗颞下颌关节紊乱综合征的疗效。
巴格达大学牙科学院的50名患有与颞下颌关节紊乱相关的肌筋膜疼痛的学生自愿参与本研究，并在治疗期和随访期接受评估。他们中有40名（80%）女性和10名（20%）男性。患者被分为两组：A组使用波长为660nm的LED（红光）的TenDlite® 204型医疗设备进行治疗，B组仅将TenDlite设备靠近压痛点但不装电池且打开设备给予安慰剂（即不进行任何治疗）。
两组的疼痛值和压痛肌肉数量变化均非常显著，只是安慰剂组变化较小但无显著差异。
本研究表明，红色LED疗法可能有助于改善患者在疼痛、弹响和压痛肌肉数量方面的症状。此外，本研究还表明了对这些患者进行心理治疗的重要性。本试验已在泰国临床试验注册中心注册，注册号为TCTR20190406002。
