To compare the effect of a rapid low-level laser therapy (LLLT) protocol to Michigan occlusal splint in the treatment of myofascial pain, as well as to evaluate their impact on Oral Health-Related Quality of Life (OHRQoL).
Thirty participants were randomly allocated into three groups: G1: occlusal splint (n = 11), G2: LLLT (n = 10), and G3: LLLT placebo (n = 9). LLLT and placebo were applied in the points of pain upon palpation.
G1 presented improvement in pain ( = 0.014) and in the diagnosis of myofascial pain ( = 0.008), while G2 and G3 did not. Regarding OHRQoL, G1 and G2 presented significant improvement ( = 0.005, in both), whereas, G3 did not.
Michigan occlusal splint was effective in reducing pain and improving OHRQoL. Treatment with the rapid LLLT protocol only provided an improvement in OHRQoL.
比较快速低水平激光疗法（LLLT）方案与密歇根咬合夹板治疗肌筋膜疼痛的效果，并评估它们对口腔健康相关生活质量（OHRQoL）的影响。
将 30 名参与者随机分配到三个组：G1：咬合夹板（n=11），G2：LLLT（n=10），G3：LLLT 安慰剂（n=9）。LLLT 和安慰剂在触诊疼痛点时应用。
G1 在疼痛（ = 0.014）和肌筋膜疼痛诊断（ = 0.008）方面均有改善，而 G2 和 G3 则没有。关于 OHRQoL，G1 和 G2 均有显著改善（ = 0.005），而 G3 则没有。
密歇根咬合夹板在减轻疼痛和提高 OHRQoL 方面有效。快速 LLLT 方案治疗仅提供了 OHRQoL 的改善。
