Temporomandibular joint disorders (TMDs) express a condition derived from a broad spectrum of etiological factors and clinical manifestations. Many treatment options have been developed for TMDs; nevertheless, conservative and non-invasive approaches ought to be prioritized. Laser therapy is an effective treatment for pain management due to its non-invasive nature and capacity for tissue regeneration. This review aimed at bringing an overview of the present evidence regarding the efficiency of laser therapy on myofascial or temporomandibular joint disorders pain. The search was conducted in four electronic databases: PubMed, Web of Science, Embase, and Scopus, of studies published between January 1997 and January 2023. The following terms have been extensively searched: "laser treatment", pain management", "temporomandibular joint disorders", "masseter muscle pain", "pterygoid muscle pain", and "temporal muscle pain". The inclusion criteria were original papers, available in full text, and written in English. Cohen's Kappa coefficient was used to assess the inter-rater reliability for article selection. The methodological quality was assessed with the Cochrane Risk of Bias tool for randomized controlled trials and the National Heart, Lung, and Blood Institute's quality assessment tool for before-after studies with no control group. Out of 846 identified records, 7 studies were included, of which 5 were randomized controlled trials. The inter-rater reliability for article selection showed an almost perfect agreement (Cohen's Kappa = 0.832, < 0.001). The protocol of laser application was not standardized; the laser wavelength ranged from 633 to 940 nm, with a power output range from 25 to 1600 mW. The number of sessions varied from 3 to 12, with a frequency of application from 1 time per week to 3 times per week. All studies reported pain reduction after laser therapy. Laser therapy is an efficient method to treat TMDs related to muscle pain. To accomplish the desired results, a standard procedure must be followed; however, the protocol is still not fully designed.
颞下颌关节紊乱病（TMDs）是一种由多种病因和临床表现引起的病症。针对TMDs已开发出多种治疗方法；然而，保守和非侵入性方法应优先考虑。激光疗法因其非侵入性和组织再生能力，是一种有效的疼痛管理治疗方法。本综述旨在概述目前关于激光疗法对肌筋膜或颞下颌关节紊乱病疼痛疗效的证据。检索了四个电子数据库：PubMed、科学网、Embase和Scopus，检索1997年1月至2023年1月发表的研究。对以下术语进行了广泛检索：“激光治疗”“疼痛管理”“颞下颌关节紊乱病”“咬肌疼痛”“翼状肌疼痛”和“颞肌疼痛”。纳入标准为全文可获取且用英文撰写的原创论文。采用Cohen卡方系数评估文章选择的评分者间信度。使用Cochrane偏倚风险工具评估随机对照试验的方法学质量，使用美国国立心肺血液研究所的质量评估工具评估无对照组的前后对照研究的方法学质量。在846条检索到的记录中，纳入了7项研究，其中5项为随机对照试验。文章选择的评分者间信度显示几乎完全一致（Cohen卡方 = 0.832，P < 0.001）。激光应用方案未标准化；激光波长范围为633至940 nm，输出功率范围为25至1600 mW。治疗次数从3次到12次不等，应用频率为每周1次到每周3次。所有研究均报告激光治疗后疼痛减轻。激光疗法是治疗与肌肉疼痛相关的TMDs的有效方法。为取得理想效果，必须遵循标准程序；然而，该方案仍未完全设计好。
