“…The maximum mouth opening also increased significantly in the laser group from the eighth session compared to those receiving 500 mg of naproxen. 39 Our study, however, failed to demonstrate any significant improvement in the mean maximum painless mouth opening between the study groups. That might somehow be attributed to the differences in laser parameters, treatment sessions, and a longer follow-up period which was 2 months after completing the treatment in their study and only 2 weeks in ours.…”

“…24,26,34,35 In our study, the laser at a 940 nm wavelength was irradiated and it resulted in a significant reduction in pain in all the patients. The positive outcome of LLLT was demonstrated in previous studies by Salmos-Brito et al, 36 Ahrari et al, 17 Mazzetto et al, 37 Shirani et al, 38 Ebrahimi et al, 18 Azizi et al, 22 and Khalighi et al, 39 who all found a significant reduction in pain intensity of TMD patients with LLLT. Khalighi et al assessed the efficacy of 810 nm galliumaluminum-arsenide diode source laser therapy versus pharmacotherapy in improving MPDS in 40 patients.…”

Introduction: Myofascial pain dysfunction syndrome (MPDS) is a common temporomandibular joint disorder. Due to its multifactorial etiology, treatment usually involves more than one modality to obtain complementary results. The purpose of this study was to compare the combined effect of a low-level laser, a hard occlusal appliance, and conventional pharmacotherapy with pharmacotherapy only in the management of patients with MPDS. Methods: In this study, 15 patients with MPDS were diagnosed and randomly assigned to 3 groups (n=5). Subjects in Group 1 were treated with pharmacotherapy (PT); Group 2 received the diode laser (940 nm gallium arsenide) every other day for a total of 10 sessions, plus pharmacotherapy (PTL) and Group 3 were given hard occlusal splint 12 h/day for 4 weeks, plus pharmacotherapy (PTO). The intensity of pain was measured using the visual analog scale (VAS) prior to the treatment, 2 and 4 weeks after the onset of treatment and 2 weeks later. The maximum painless mouth opening and pain intensity at muscle palpation were also recorded. Comparisons were made between the groups via repeated measure analysis of variance (ANOVA) (P<0.05). Results: Pain relief in the subjective VAS was observed in both laser and appliance groups in the third and fourth examination sessions (P<0.05). No statistically significant reduction in pain was noted using pharmacotherapy only. The maximum painless mouth opening and muscle tenderness were not significantly different between the 3 groups (P>0.05). Conclusion: Both the laser and the occlusal appliance combined with pharmacotherapy proved to be effective for pain reduction in patients with MPDS. All groups, however, failed to result in a significant improvement in the maximum mouth opening or tenderness in masticatory muscles.

“…Several studies showed that LLL can reduce the pain in TMD patients. 4,[10][11][12]22,29,[32][33][34][35] Maximum mouth-opening, pain, and muscle tenderness were the criteria recorded in the present study. After the last session, mouth-opening had significantly decreased in all groups.…”

Comparative effectiveness of Low Level Laser therapy and Transcutaneous Electric Nerve Stimulation on Temporomandibular Joint Disorders

IntroductionTemporomandibular joint disorder (TMD) is a general term for clinical problems in temporomandibular joints (TMJs), masticatory muscles, and surrounding tissues, which manifest as limitations in motion and joint sounds. 1 TMD is the second most-common skeletal-muscular problem and one of the most common chronic problems involving orofacial pain, discomfort and disability. Approximately 75% of the population has several symptoms of TMD and 33% have at least one symptom. 2-5The etiology of TMD, especially muscle pain, is multifactorial and includes parafunctional habits, trauma, stress, heredity and occlusal factors 5 ; thus, conservative and reversible treatment, especially during initial periods, is recommended. 5,6 Several treatments have been suggested to control pain and symptoms. These include orthopedic stabilization, intraoral devices, medications (analgesics, muscle relaxants, antidepressants, and placebos) and physical therapy. 5 The aim of physical therapy is muscle relaxation, a decrease in pain, spasms, swelling and inflammation, and joint stability. Methods:In this single-blind study, 40 patients with temporomandibular disorders were randomly divided into four groups: TENS (TENSTem dental), LLL (diode 810 nm CW), sham-TENS, and sham-LLL. All subjects were examined and data on pain and tenderness in the temporomandibular joint (TMJ) and masticatory muscles (using the visual analogue scale) and mouth-opening (distance between incisal edges before feeling pain; mm) were collected before baseline (T1), after each session (T2-T5) and one month after the end of the sessions (T6)), and analyzed using repeated measure analysis of variance (ANOVA) and Bonferroni statistical tests. A P value < 0.05 was considered significant. Results:The decrease in pain (P = 0.000), tenderness (P = 0.000) and increase in mouth-opening ability (P = 0.002) was greater in the TENS and LLL groups than in the placebo groups. At the one-month follow-up, significant decrease in pain and tenderness was recorded in the TENS and LLL groups (P = 0.000). There was no significant differences between TENS and LLL and the placebo groups for maximum mouth-opening at the end of the study (P = 0.692). Conclusion: Using TENS or LLL therapy can improve TMD symptoms at least for the short term. Although the effects of the placebo played a role in improving symptoms, their effects were less important.

“…10 Therefore, medications play an important role in the treatment of TMD patients, since 90% of these patients report pain as the main complaint, which generates disability and socioeconomic costs. 10,11 Pharmacotherapy for TMD usually occurs empirically. Although the prescription is extensive, there is a lack of specific scientific evidence for the pathology.…”

Introduction: Temporomandibular Disorders (TMD) are defined as a set of painful and/or dysfunctional conditions related to masticatory muscles, Temporomandibular Joint (TMJ) and associated structures. This study proposed to evaluate the prevalence of TMD symptoms in dentists from Fortaleza, one Brazilian city, relating the age group, gender and time of professional performance. Materials and Methods: This is a crosssectional, descriptive-analytical research. A total of 495 dentists were selected, of which 55.8% (n= 276) were females and 44.2% (n= 219) were males, with a professional working time up to 10 years (69.1%, n= 342), up to 30 years old (57.0%; n= 282). Results: When asked about the movements that interfered with weekly pain according to European Academy of Craniomandibular Disorders (EACD), the majority of the participants reported no pain (p<0.01), among the ones who answered yes, headache was the most prevalent (31%, n= 70), followed by pain in the temples, face, TMJ or mandible (17.3%; n= 39). In relation to participants who responded to have pain symptoms, headache was the most prevalent symptom. Regarding the search for treatment, the majority pointed to seek treatment with a neurologist. Despite several pain symptoms reported, most participants rated their own health with an average of 8.69±1.35. Conclusion: In spite of the several studies on the prevalence of TMD in the literature, there are still few studies evaluating the prevalence of TMD symptoms in dentists.
