“…Ahrari et al [28] evaluated the effect of 810nm LLL in patients with myofascial pain one month after treatment and concluded that the effects of reducing the intensity of the pain and the increase in the mouth opening range were maintained. Some placebo-controlled studies indicated that LLLT was not effective compared to placebo [13,14,29]. In contrast, a recent study by Magri et al showed that there was no difference in the effects of active LLL or placebo on the decrease in pain intensity measured by VAS scale and sensory and affective pain components [29].…”

“…Many studies have confirmed the effectiveness of low-level laser therapy in decreasing pain and improving the function of orofacial system in patients with TMDs [7][8][9][10][11][12]. On the other hand, the results of some placebo-controlled studies negate the positive effects of LLLT in reducing pain and improving function of orofacial system compared to placebo [13,14]. Since the results of previous research are inconsistent, increasing attention in the research is attributed to finding adequate radiation characteristics and LLLT protocols in TMD management.…”

Introduction/Objective. Low-level laser therapy has been suggested as an alternative pain relief therapy in temporomandibular disorders patients. The aim of this study was to examine the effects of Low-level laser therapy on reducing pain intensity in temporomandibular disorders patients, compared to non-steroidal anti-inflammatory drugs. Methods. A total of 63 patients diagnosed with Research Diagnostic Criteria for Temporomandibular Disorders were divided into two groups. In the first group of 35 patients low-level laser therapy was applied three times a week, 15 treatment sessions during 5 weeks (Wavelength: 780 nm; Power density: 70 mW/cm2; Radiant energy: 4.2 J; Energy density: 4.2 J/cm2; Total treatment dose: 16.8 J/cm2;). The second group included 28 participants subjected to nonsteroidal anti-inflammatory drugs therapy (ibuprofen) during two weeks (first three days 3 ? 400 mg, remaining time 2 ? 400 mg per day). Pain was evaluated using 100 mm Visual Analog Scale, at the baseline, during therapy, two weeks and three months after treatments. Results. Statistically significant reduction of pain intensity was achieved both, in low-level laser therapy and in nonsteroidal anti-inflammatory drugs therapy groups and remained steady in the follow-up period of three months (p <0.01). Differences in Visual Analog Scale scores between observed groups were not statistically significant in each of the evaluation periods, (p = 0.375, p = 0.665, p = 0.52, respectively). Conclusion. The low-level laser therapy protocol applied in this research was efficient in reducing pain in temporomandibular disorders patients.

“…Surface EMG, myofunctional procedure ratings, and assessment of masticatory efficiency are some of the employed objective approaches [ 42 ]. This systematic review also focused on improving the secondary outcomes like MO [ 5 , 9 , 10 , 14 – 16 , 26 , 28 , 30 , 34 , 37 , 43 – 47 ], LE and PE mandibular movements [ 10 , 14 – 16 , 26 , 28 , 34 , 37 , 43 – 46 , 48 ], PPT [ 14 , 34 , 35 , 44 , 46 , 49 , 50 ], EMG parameters [ 32 , 34 ], joint noises [ 5 , 28 ], TMD masticatory efficiency (ME) [ 49 , 51 ], subjective tinnitus [ 29 ], and occlusal contacts distribution [ 48 ].…”

“…The studies showed that the number of sessions per week ranged from 1–7. Most of the studies argued for 2 sessions per week [ 5 , 11 , 13 , 14 , 26 , 28 , 32 , 35 , 37 , 43 , 45 , 49 – 51 , 56 , 57 ]. However, there was no mention of the number of sessions/weeks in a few studies [ 25 – 28 , 30 , 34 , 47 ].…”

Low-level laser therapy in temporomandibular joint disorders: a systematic review

et al. 2021

Temporomandibular joint disorders (TMDs) encompass a wide array of ailments affecting the temporomandibular joint (TMJ), muscles of mastication, and the allied structural framework. Myofascial pain, internal derangement of the joint, and degenerative joint diseases constitute the majority of TMDs. TMDs usually have a multifactorial etiology, and treatment modalities range from conservative therapies to surgical interventions. Low-level laser therapy (LLLT) has evolved as an efficient non-invasive therapeutic modality in TMDs. Previously conducted systematic reviews and meta-analyses have shown variable results regarding the efficiency of LLLT in TMJ disorder patients. Hence, this systematic review was carried out as an attempt to evaluate the efficacy of LLLT in the treatment of temporomandibular joint disorder patients.

“…The interincisal distance between the maxillary and mandibular incisal edges was measured by a ruler 18 . The magnitude of lateral jaw displacement was measured as the horizontal distance between the midpoints of the upper and lower central incisors 19 . In this study, ROM was evaluated at baseline, at week 1 and at week 4.…”

Background Interventions addressing pain and impaired functionality in individuals with temporomandibular disorders (TMDs) are needed. Objective To compare the effects of 4 weeks of exercise combined with ischaemic compression and exercise alone in patients with TMDs. Methods Fifty patients who were diagnosed with TMDs were randomised into Group 1 (exercise combined with ischaemic compression technique) (n = 25) or Group 2 (exercise alone) (n = 25). Both groups performed 4 weeks of Rocabado's exercise and 3 weeks of postural exercise, while Group 1 received ischaemic compression to the masseter muscle for a total of 3 sessions in addition to exercise. A ruler was used to assess range of motion (ROM) (painless mouth opening (PMO), maximum mouth opening, maximum assisted mouth opening (MAMO), left lateral movement and right lateral movement), the visual analogue scale and graded chronic pain scale were used to assess pain, an algometer was used to determine the pain pressure threshold (PPT), and the 8‐item jaw functional limitation scale was used to assess, functionality. The assessments were performed at baseline, at week 1 and at week 4. Results The participants in Group 1 exhibited larger PMO (F = 5.26, P = .02) and MAMO values (F = 6.71, P = .01) than did the patients in Group 2 at week 1. The effect size was small for MAMO (ES = 0.27) and moderate for PMO (ES = 0.51). However, there were no significant differences in any other outcomes between groups at week 1 or 4. Conclusion In summary, this randomised controlled trial indicates that exercise combined with ICT and exercise alone have similar effects on ROM, pain, the PPT and functionality in patients with TMDs.
