Can the severity of orofacial myofunctional conditions interfere with the response of analgesia promoted by active or placebo low-level laser therapy?

To analyze the influence of orofacial myofunctional condition (OMC) on pain perception, temporomandibular disorders (TMD) severity, and the response to low-level laser therapy (LLLT) in women with painful TMD. Seventy-eight women, 59 with TMD, received active laser (30) or placebo (29), with 19 cont...

Description
Summary:To analyze the influence of orofacial myofunctional condition (OMC) on pain perception, temporomandibular disorders (TMD) severity, and the response to low-level laser therapy (LLLT) in women with painful TMD. Seventy-eight women, 59 with TMD, received active laser (30) or placebo (29), with 19 controls. OMC, TMD severity, pain intensity, and pressure pain threshold (PPT) were assessed at different times during the masticatory test: before treatment (LLLT dose: 780nm), during, and after 30 days. No correlation was found between OMC and pain perception or TMD severity (p > 0.05). The active and placebo LLLT showed reduction of pain during chewing and better recovery levels during the rest period (p > 0.05), without differences between OMC groups. The perception of pain and severity of TMD are not correlated with the OMC, and the response of analgesia promoted by active LLLT or placebo is not associated with OMC.
