The main symptoms of temporomandibular disorders (TMDs) are pain from musculoskeletal and/or joint-in the head and neck region-and complaints of difficulty in mandibular movements. The photobiomodulation therapy (PBMT) has been reported as a promising treatment in the management of these symptoms. The objective of this research was to assess the effect of PBMT immediately after irradiation on TMDs symptoms under a prospective clinical trial, randomized, triple-blinded, placebo-controlled, and with two parallel arms. According to the RDC/TMD, maximum mouth opening (MMO) and pain in the orofacial/cervical muscles and temporomandibular joint (TMJ) were recorded. One hundred forty-five participants (71 placebo and 74 PBMT experimental) were analyzed after irradiation protocols (sham-PBMT or PBMT) at the orofacial/cervical skull musculature and at the TMJ. The results showed a reduction in the total pain score ( = 0.026), a reduction in the number of painful points ( = 0.013), and an increase in the MMO ( = 0.016) in the PBMT protocol group when compared to the placebo protocol (sham-PBMT). The PBMT was shown to be effective in reducing orofacial/cervical skull pain immediately after the irradiation. It is clinically relevant and should be taken into consideration by professionals who are dedicated to treating this pathology because, in addition to bringing comfort to patients who need dental treatment, it also consists of a low-cost and low technical complexity clinical approach.
颞下颌关节紊乱病（TMDs）的主要症状是头颈部肌肉骨骼和/或关节疼痛，以及下颌运动困难的主诉。光生物调节疗法（PBMT）已被报道为治疗这些症状的一种有前景的方法。本研究的目的是在前瞻性临床试验中，评估照射后立即进行PBMT对TMDs症状的影响，该试验为随机、三盲、安慰剂对照且有两个平行组。根据RDC/TMD，记录最大开口度（MMO）以及口面部/颈部肌肉和颞下颌关节（TMJ）的疼痛情况。在对面部/颈部颅骨肌肉组织和TMJ进行照射方案（假PBMT或PBMT）后，对145名参与者（71名安慰剂组和74名PBMT试验组）进行了分析。结果显示，与安慰剂方案（假PBMT）相比，PBMT方案组的总疼痛评分降低（P = 0.026），疼痛点数减少（P = 0.013），MMO增加（P = 0.016）。结果表明，PBMT在照射后能立即有效减轻口面部/颈部颅骨疼痛。它具有临床相关性，致力于治疗这种疾病的专业人员应予以考虑，因为它除了能为需要牙科治疗的患者带来舒适外，还是一种低成本且技术复杂性低的临床方法。
