Aims: To conduct a systematic review and meta-analysis to determine the efficacy of low-level laser therapy (LLLT) in treating temporomandibular myofascial pain in adults compared to laser placebo.
Methods: Randomized, placebo-controlled studies were identified by a search on March 2, 2016 and updated on February 9, 2017 in the PubMed, Web of Science, and Cochrane Library databases. Three of the authors assessed the studies for risk of bias. Outcomes included pain reduction on a visual analog scale (VAS) and interincisal opening.
Results: The initial search strategy yielded 142 unduplicated references assessed independently by three review authors. After evaluation, this number was reduced to eight relevant studies for inclusion in this review. Of these eight studies, four were at unclear risk of bias and four were at high risk. In a meta-analysis, pain intensity was significantly reduced after treatment in the group that received LLLT as compared to laser placebo (an average of 2.2 units on a scale of 0 to 10) (P = .005) and an average of 2.4 units 3 to 4 weeks later (P = .022). Pooled results showed a significant increase in interincisal opening at 1 month after treatment (P = .012), but not when the treatment was completed (P = .079).
Conclusion: The findings from this systematic review showed that LLLT seems to be effective in reducing pain in patients with temporomandibular myofascial pain with moderate-quality evidence. However, due to the high heterogeneity, small number, and high risk of bias of the included studies, the results are not definitive, and further well-designed studies are needed.

Temporomandibular disorder (TMD) is considered a complex disorder that follows the biopsychosocial model. The current study aimed to explore the effect of clinic location and referring physicians on the distribution of Axis I diagnoses according to the Diagnostic Criteria for TMD (DC/TMD). Eighty-eight patients from a dental school Orofacial Pain Clinic (DentalOFP) and 104 patients from a hospital Orofacial Pain Clinic (HospitalOFP) were examined by the same dentist who was certified as a DC/TMD examiner and compared.

The aims of the study are to analyze the influence of pain and no pain expectations on the physiological (electromyography (EMG) and pupillometry) and cognitive (Numerical Rating Scale (NRS)) response to pain. Pain expectation and no pain expectation situations were induced by employing instructional videos. The induction of pain was performed by palpating the masseter with an algometer in a sample of 2 groups: 30 healthy participants (control group) and 30 patients (Temporomandibular disorders (TMD) group) with chronic myofascial pain with referral in the masseter muscle (Diagnostic Criteria for Temporomandibular Dissorders (DC/TMD)).

Myofascial pain is one of the common symptoms in patients with temporomandibular joint disorders (TMD). Occlusal splint (OS) and masticatory muscle trigger point (TP) local injections are primary treatment options. We aimed to investigate the effects of these treatments using clinical and elastography measures.

Objective: The aim of this study was to design and use a headache diary in patients with frequent tension-type headaches (TTH). Another aim was to assess the relationship among oral behaviors, range of motion, and tenderness to palpation of the craniomandibular muscles.
Methods: Thirty-four patients participated in this prospective observational study for a 3-month period at the Adavall Clinic for Physiotherapy and Rehabilitation (Valladolid, Spain) in 2019.

To test the effectiveness of an 8-week exercise program targeted to the neck muscles compared to manual therapy, and placebo treatments on orofacial pain intensity, jaw function, oral health-related quality of life (OHRQoL), and jaw range of motion (ROM) in women with Temporomandibular Disorders (TMD). In this randomized controlled trial, fifty-four women (between 18-45 years old) with a diagnosis of myofascial or mixed TMD according to the Research Diagnostic Criteria for TMD (RDC/TMD) were randomized into three groups: Neck motor control training (NTG), Manual Therapy Group (MTG), and Placebo Group (PG). All patients were evaluated with the Visual Analog Scale, Mandibular Function Impairment Questionnaire, Oral Health Impact Profile-14, and jaw Range of Motion (ROM) at baseline, immediately after treatment (after 8 weeks of treatment), one month, and three-month follow-up.
