A pilot study on the use of low level laser therapy in treatment of temporomandibular disorder
2018
Temporomandibular disorders (TMDs) is a collective term that embracing a number of clinical problems that involve the masticatory muscles, Temporomandibular Joint (TMJs), and the associated structures. It characterized by facial pain in the area of TMJ and muscle of mastication, restriction and sound during mandibular movement. Recently physical therapy such as Low Level Laser Therapy (LLLT) is used as one of the treatment modalities and it is believed to promote wound healing, tissue repair and induce analgesia. Convenience sampling was used which consist of 22 volunteered patients, 14 were treated with conventional treatment and 8 were treated with combination of LLLT and conventional therapy. Laser machine used was Waterlase/Biolase © 2007 with irradiation 0.5 W-30 Hz daily for three consecutive days, then once a week review treatment for two weeks. The space between laser beam and skin is 3 cm, applied as small circles for 2-3 minutes. Pain intensity before and after the treatment was recorded by using numerical rating scale (NRS). Statistical data analysis was conducted using SPSS software. Wilcoxon-sign ranked-test and Mann-Whitney U test were used. Pain intensity was reduced significantly in patients whom treated by combination of LLLT and conventional therapy. (p<0.05). Pain intensity after treatment for female were higher (M=1.20, SD=1.10) than for male (M=0.00, SD=0.00). Younger patients have higher pain intensity than older patients. LLLT is effective to be used as adjunct to the current conventional treatment in relieving pain in TMDs. Clinical article (J Int Dent Med Res 2018; 11(2): pp. 669-675
Evaluation of Low-Level Laser Therapy in the Treatment of Temporomandibular Disorders
Photomedicine and Laser Surgery, 2006
Objective: The purpose of this study was to assess the effectiveness of low-level laser therapy (LLLT) in the treatment of myogenic originated temporomandibular disorders (TMD). Background Data: Limited studies have demonstrated that LLLT may have a therapeutic effect on the treatment of TMD. Methods: Thirty-nine patients with myogenic TMD-associated orofacial pain, limited mandibular movements, chewing difficulties, and tender points were included in this study. Twenty-four of them were treated with LLLT for 10 sessions per day excluding weekends as test group, and 15 patients with the same protocol received placebo laser treatment as a control group. These parameters were assessed just before, just after, and 1 month after the treatment. Results: Maximal mouth-opening improvement, and reductions in pain and chewing difficulty were statistically significant in the test group when compared with the control group. Statistically significant improvements were also detected between two groups regarding reduction in the number of tender points. Conclusion: Based on the results of this placebo-controlled report, LLLT is an appropriate treatment for TMD and should be considered as an alternative to other methods.
Effectiveness of low‐level laser therapy in temporomandibular disorder
Scandinavian Journal of Rheumatology, 2003
Objective: To investigate the effectiveness of low-level laser therapy in the treatment of temporomandibular disorder and to compare treatment effects in myogenic and arthrogenic cases. Methods: Thirty-five patients were evaluated by magnetic resonance imaging and randomly allocated to active treatment (n~20) and placebo treatment (n~15) groups. In addition to a daily exercise program, all patients were treated with fifteen sessions of low-level laser therapy. Pain, joint motion, number of joint sounds and tender points were assessed. Results: Significant reduction in pain was observed in both active and placebo treatment groups. Active and passive maximum mouth opening, lateral motion, number of tender points were significantly improved only in the active treatment group. Treatment effects in myogenic and arthrogenic cases were similar. Conclusion: Low-level laser therapy can be considered as an alternative physical modality in the management of temporomandibular disorder.
Evaluation of low-level laser therapy in patients with acute and chronic temporomandibular disorders
Lasers in Medical Science, 2012
The purpose of this study was to address the following question: among patients with acute or chronic temporomandibular disorders (TMD), does low-level laser therapy (LLLT) reduce pain intensity and improve maximal mouth opening? The sample comprised myogenic TMD patients (according Research Diagnostic Criteria for TMD). Inclusion criteria were: male/female, no age limit, orofacial pain, tender points, limited jaw movements and chewing difficulties. Patients with other TMD subtypes or associated musculoskeletal/rheumatologic disease, missing incisors teeth, LLLT contra-indication, and previous TMD treatment were excluded. According to disease duration, patients were allocated into two groups, acute (<6 months) and chronic TMD (≥6 months). For each patient, 12 LLLT sessions were performed (gallium-aluminum-arsenide; λ0 830 nm, P040 mW, CW, ED08 J/cm 2). Pain intensity was recorded using a 10-cm visual analog scale and maximal mouth opening using a digital ruler (both recorded before/ after LLLT). The investigators were previously calibrated and blinded to the groups (double-blind study) and level of significance was 5% (p<0.05). Fifty-eight patients met all criteria, 32 (acute TMD), and 26 (chronic TMD). Both groups had a significant pain intensity reduction and maximal mouth opening improvement after LLLT (Wilcoxon test, p<0.001). Between the groups, acute TMD patient had a more significant pain intensity reduction (Mann-Whitney test, p00.002) and a more significant maximal mouth opening improvement (Mann-Whitney test, p00.011). Low-level laser therapy can be considered as an alternative physical modality or supplementary approach for management of acute and chronic myogenic temporomandibular disorder; however, patients with acute disease are likely to have a better outcome.
Lasers : A Boon In The Management Of Temporomandibular Disorders
Temporomandibular disorders have been identified as the most important cause of pain in the facial region. Pain relief and reestablishment of normal masticatory function are the main goals of conservative management of Temporomandibular Disorders (TMD). Laser therapy is a part of the treatment modality that have demonstrated to have an analgesic, anti-inflammatory and biostimulating effect. The LLLT is a non invasive , quick and safe, non pharmacological intervention that may be beneficial for patient with TMDs. This review article projects the use of LLLT for management of temporomandibular disorders ,its mode of action and also gives a review on various studies conducted to assess its efficacy on pain management.

Low-level laser therapy has still not been well established, and it is important to define a standardized protocol for the treatment of temporomandibular disorders (TMDs) using low level laser. There is no consensus on controlled clinical trials concerning the best option for laser therapy with regard to wavelength. The aim of this study was to evaluate the efficacy of red and infrared laser therapy in patients with TMD, using a randomized parallel-group double-blind trial. Methodology: Each hemiface of 19 subjects was randomized to receive intervention, in a total of 116 sensitive points. Pain was measured at baseline and time intervals of 24 hours, 30 days, 90 days, and 180 days after treatment. Irradiation of 4 J/cm 2 in the temporomandibular joints and 8 J/cm 2 in the muscles was used in three sessions. Results: Both treatments had statistically significant results (P,0.001); there was statistical difference between them at 180 days in favor of the infrared laser (P50.039). There was improvement in 24 hours, which extended up to 180 days in both groups. Conclusion: Both lasers are effective in the treatment and remission of TMD symptoms.

Objective: The purpose of this clinical study is to assess the capability of low-level laser therapy (LLLT) in the treatment of temporomandibular joint disorders (TMJDs). Materials and methods: Twenty-four temporomandibular disorder (TMD) patients were selected based on TMD pain screening, Wong and Baker pain scale, and clinical evaluation for signs of TMJDs. Sixteen patients were randomly selected and placed in an experimental group, and a placebo group comprised of eight patients. Painful muscular areas were identified by digital pressure, and laser was applied to these areas for an average of 300 seconds for each patient. The laser device was directed to painful areas without emission in the placebo group. Patients were evaluated before and immediately after each session and after 1 month. Results: Before and after treatment, the changes in pain levels in group I were statistically significant (p < 0.0001). The changes in pain levels before and after treatment in group II did not show any statistical significance (p = 1.000). The results were statistically significant (p = 0.000), on comparing the pain levels after 1 month in groups I and II. Conclusion: The results revealed a significant amount of pain reduction after LLLT on a short-term basis, the majority of patients reported a decrease in clicking frequency, and a softer mandibular movement compared with the placebo group. Clinical significance: The LLLT can be advocated as an adjunct in reducing pain levels in most TMJDs on a short-term basis. Observations from this study second this view.
