Temporomandibular disorder (TMD) is a variety of clinical problems that originate from the area of the temporomandibular joint (TMJ), masticatory muscles, and surrounding tissues. There are different treatment options; however, there is no evidence that low level laser treatment (LLLT) will last about six months. The aim of this study was to determine the survival rate of treatment with red (660 nm) and infrared (790 nm) laser in cases of TMDs.
In 19 subjects, one side of the face (half face) was randomly selected to receive intervention, in a total of 116 sensitive points. Pain was measured at baseline and time intervals of 24 h, 30, 90, and 180 days after treatment. Laser irradiation with 4 j/cm² in the TMJs and 8 j/cm² in the muscles was used in three sessions. Kaplan-Meier survival analysis and logistic regression were performed.
Both treatments showed statistically significant results (p < 0.001). The survival rate for red and infrared laser was 0.24 and 0.30, respectively, at 180 days. Grinding teeth and headache were associated with recurrent pain.
Both lasers were effective in the treatment of TMD symptoms and had a low survival rate at 180 days.
颞下颌关节紊乱病（TMD）是源自颞下颌关节（TMJ）、咀嚼肌及周围组织区域的一系列临床问题。有多种治疗选择；然而，尚无证据表明低强度激光治疗（LLLT）的效果能持续约六个月。本研究的目的是确定红色（660纳米）和红外（790纳米）激光治疗TMD的生存率。
在19名受试者中，随机选择一侧面部（半侧脸）接受干预，共116个敏感点。在基线以及治疗后24小时、30天、90天和180天的时间间隔测量疼痛程度。在颞下颌关节处以4焦耳/平方厘米、在肌肉处以8焦耳/平方厘米进行三次激光照射。进行了Kaplan-Meier生存分析和逻辑回归分析。
两种治疗均显示出具有统计学意义的结果（p < 0.001）。在180天时，红色激光和红外激光的生存率分别为0.24和0.30。磨牙和头痛与复发性疼痛相关。
两种激光在治疗TMD症状方面均有效，且在180天时生存率较低。
