Pain, limitations in opening, asymmetrical jaw movements, and temporomandibular joint (TMJ) sounds are the most common findings in temporomandibular joint disorders (TMDs), which causes excruciating pain, inflammation of the surrounding muscles, posterior fibers, and synovial fluid. This study aimed to evaluate and compare the effects of ultrasound heat therapy and low-level laser therapy (LLLT) in reducing TMD-related pain.
This prospective study included 42 patients (age range, 25-45 years), who were divided into two groups of 21 patients each. All patients were prescribed a non-steroidal anti-inflammatory drug (NSAID) twice a day for 5 days for temporary relief of pain prior to the commencement of treatment. Patients were kept on a soft diet and asked to restrict mouth opening during the same period. Fifteen sessions of LLLT (Group A) or ultrasound therapy (Group B) were administered to the affected side.
Post-therapy, the mean visual analog scale score for group A and group B was 4.81 (2.01) and 6.19 (1.20), respectively; the difference was statistically significant and favoring the LLLT group. Similarly, the mean mouth opening for group A and group B was 3.99 (0.40) and 3.65 (0.41), respectively; the difference was statistically significant and favoring the LLLT group.
Our study recommends LLLT for treating TMD-related pain with no underlying bony pathology.
疼痛、开口受限、不对称的下颌运动以及颞下颌关节（TMJ）弹响是颞下颌关节紊乱病（TMDs）最常见的表现，该病会引发剧痛、周围肌肉、后纤维及滑液的炎症。本研究旨在评估和比较超声热疗与低强度激光疗法（LLLT）在减轻TMD相关疼痛方面的效果。
这项前瞻性研究纳入了42例患者（年龄范围25 - 45岁），分为两组，每组21例。所有患者在治疗开始前每天服用两次非甾体抗炎药（NSAID），持续5天以暂时缓解疼痛。在此期间，患者保持软食，并被要求限制开口。对患侧进行15次LLLT（A组）或超声治疗（B组）。
治疗后，A组和B组的平均视觉模拟量表评分分别为4.81（2.01）和6.19（1.20）；差异具有统计学意义，且LLLT组更优。同样，A组和B组的平均开口度分别为3.99（0.40）和3.65（0.41）；差异具有统计学意义，且LLLT组更优。
我们的研究推荐LLLT用于治疗无潜在骨质病变的TMD相关疼痛。
