Temporomandibular Joint Pain

Since nitric oxide is related to nociception and the sleep-wake cycle, this study sought to determine its involvement in the altered sleep pattern in a temporomandibular joint pain model by investigating the effect of the inhibitor of nitric oxide synthase (L-NAME) and that of its precursor (L-arginine). The temporomandibular joints of test animals were injected with Freund’s adjuvant or saline, and their sleep was recorded. The procedure was repeated after the administration of L-NAME and L-arginine. L-NAME increased rapid eye movement (REM) sleep in the control group. The orofacial pain group showed a reduction in total sleep time and an increase in sleep latency compared with the SHAM group. L-NAME increased sleep time, non-rapid eye movement (NREM), and REM sleep and reduced sleep latency in the orofacial pain group. L-arginine did not alter sleep parameters. Thus, L-NAME improved sleep efficiency, whereas L-arginine did not modify it, suggesting the involvement of nitric oxide in painful temporomandibular joint conditions.

Craniocervical Dystonia

Temporomandibular disorders are a set of musculoskeletal dysfunctions within the masticatory system, with multiple etiologies. OBJECTIVE: Since craniocervical dystonia can involve the same neuromuscular structure as the temporomandibular joint, we sought to assess the correlation between temporomandibular disorders and craniocervical dystonia. METHOD: We applied the Research Diagnostic Criteria for Temporomandibular Disorders to 42 patients with craniocervical dystonia, in order to identify orofacial pain and temporomandibular characteristics on the day of botulinum toxin injection. RESULTS: Twenty-two patients (52.3%) reported temporomandibular joint pain; 24 (57.1%), joint sounds; 20 (47.6%), masticatory muscle pain; and 21 (50%), diminished jaw mobility. The patients with oromandibular dystonia presented temporomandibular disorders more frequently than did patients with other types of craniocervical dystonia (p<0.001). CONCLUSION: Temporomandibular disorders occur frequently in patients with oromandibular dystonia. Further studies should address the proper treatment of temporomandibular disorders associated with dystonia.

Temporomandibular Joint Pain

Abstract Background: Orofacial pain may have an impact on quality of life. It may affect the overall well-being of an individual. Objective: To assess the prevalence of orofacial pain and its impact on quality of life in early adolescents in Indore city, India. Methods: This was a cross-sectional study which included a total of 800 children selected from various public and private schools located in Indore city, India. A questionnaire was developed which collected information on sociodemographic characteristics and previous dental visits. The severity of pain was assessed using Von Korff pain scale and quality of life using the General Health Questionnaire 12 (GHQ-12). The chi-square test and logistic regression analysis were performed. Results: The overall prevalence of orofacial pain was found to be 17.9%. Toothache (10.1%) was found to be the most prevalent orofacial pain followed by temporomandibular joint pain (4.3%). The highest severity of pain (Grades 3 and 4) was reported for toothache followed by temporomandibular joint pain. The results of the logistic regression model showed that the prevalence of orofacial pain (odds ratio=7.18, p-value<0.0001a) was strongly associated with poor quality of life. Conclusion: The orofacial pain has a negative influence on the quality of life of adolescents. Effective policies should be created to improve the quality of life of adolescents focusing on oral health education and prevention of oral diseases.

Background: Temporomandibular Joint (TJ) pain and orofacial myalgia (OM) are the most significant problems in physiotherapy context to treat in Cervicofacial burn (CB). However, there is a lack of clinical studies in investigating the effects of electro acupuncture therapy on TJ pain with OM following post healed CB patients.<br/> Objective: To investigate the effects of clinical and functional efficacy of electro acupuncture therapy on temporomandibular joint pain with orofacial myalgia following post healed cervicofacial burn patients.<br/> Methods: Through two block random sampling method, the eligible participants were randomized and allocated into active EAT (Active-EAT; n = 15) and placebo EAT (Placebo-EAT; n = 15) groups. The Active-EAT group received electro acupuncture therapy and the Placebo-EAT group received placebo effect with regular physiotherapy care for 4 times in a week for 4 weeks. Primary (pain intensity, pain threshold, pain frequency) and secondary (mouth opening, disability level and quality of life) measures were measured at baseline, after the 4th week, 8th week and 6 month follow up.<br/> Results: Baseline demographic and clinical attributes show homogenous presentation among the study groups (p > 0.05). After 4 weeks of treatment, and at the end of 6 months follow up, the pain intensity, 3.0 (CI 95% 2.83 to 3.16), pain threshold 18.6 (CI 95% -35.0 to -2.1), pain frequency 2.9 (CI 95% 2.54 to 3.25), mouth opening, -13.4 (CI 95% -15.1 to -11.6), disability level 12.4 (CI 95% 12.16 to 12.63), and quality of life -25.8 (CI 95% -31.0 to -20.5) showed more improvement (p < 0.001) in Active-EAT group than Placebo-EAT group.<br/> Conclusion: The reports of this study proved that, 4 weeks active electro acupuncture therapy with regular physiotherapy care has an ideal treatment protocol for temporomandibular joint pain with orofacial myalgia following post healed cervicofacial burn. This study also provided a new knowledge for physiotherapists in the field of TJ rehabilitation.
