Evaluation of pain threshold upon palpation of the masticatory muscles in women with temporomandibular disorder according to the Research Diagnostic Criteria of Temporomandibular Disorders

ABSTRACT Purpose: to evaluate the pain threshold upon palpation of the masticatory muscles in women with temporomandibular disorder (TMD) according to the Research Diagnostic Criteria of Temporomandibular Disorders (RDC/TMD). Methods: a cross-sectional study was conducted involving the evaluation of pain threshold upon palpation of the extraoral muscles (temporal, masseter, posterior mandibular region, submandibular region) and intraoral muscles (lateral pterygoid area and temporal tendon) in women using the RDC/TMD clinical examination. Results: 60 women were evaluated. Statistically significant differences were found among the muscles evaluated regarding the pain threshold. The lateral pterygoid area, bilaterally, had the lowest pain threshold, followed by the masseter and temporal muscles. Conclusion: this study suggests that the lateral pterygoid muscle, bilaterally, has the lowest pain threshold upon palpation among the masticatory muscles, followed by masseter and temporal muscles, in women with TMD, according to the RDC/TMD evaluation.

Introdução: A Disfunção Temporomandibular (DTM) é um quadro patológico que afeta o sistema estomatognático e, frequentemente, acompanhada de dor. Objetivos: Aferir o nível de dor dos pacientes portadores de DTM e a prevalência de sintomatologia articular e muscular. Percebeu-se que a relação entre a origem da DTM e a sintomatologia dolorosa é pouco relatada na literatura. Materiais e Métodos: Trata-se de um estudo descritivo, observacional de corte transversal, desenvolvido com 30 pacientes com DTM, diagnosticado pelo Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). A amostra foi determinada pelas estimativas de atendimento. A associação entre a sintomatologia e a origem da DTM foram verificadas através do teste qui-quadrado, com intervalos de confiança (95%). Foi usada uma ficha clínica para a coleta de dados com idade, gênero e nível da dor, que foi aferido através da Escala Visual Analógica de dor. Resultados: Constatou-se que 26 pacientes eram do sexo feminino e 4 do sexo masculino. Quinze apresentaram idade inferior a 36,5 anos, e os outros uma idade superior a esta. Quanto a origem da DTM, 19 tinham desordem articular e 11 muscular. A categoria moderada foi o nível mais prevalente, seguida do intenso. Determinou-se que não houve associação estatisticamente significante entre as variáveis deste estudo com a DTM. Conclusão: Constatou-se que, os fatores etiológicos analisados isoladamente não influenciam de forma única no desenvolvimento da DTM, mas poderão atuar em conjunto com outros fatores, já que a sua causa é multifatorial.Descritores: Dimensão Vertical; Boca Edêntula; Dor Facial; Síndrome da Disfunção da Articulação Temporomandibular.ReferênciasDworkin SF, LeResche L.

Prevalence Of Pain

Purpose:This study aimed to establish the prevalence of pain in the craniomandibular and cervical spine region in individuals with Temporomandibular Disorders (TMD) and to analyze the effects of these disorders on the bilateral activation of anterior temporalis (AT) and masseter (MA) muscles during the masticatory cycle.Methods:The participants were 55 female volunteers aged 18–30 years. The presence of TMD and craniomandibular and cervical spine pain was evaluated by applying the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire and using a combination of tests for the cervical region. The muscle activity of AT and MA during the masticatory cycle was assessed using the symmetry and antero-posterior coefficient indices.Results:The AT activity during the masticatory cycle is more asymmetric in individuals with TMD. The craniomandibular pain, more prevalent in these individuals, influenced these results.Conclusion:Individuals with TMD showed changes in the pattern activity of AT. The craniomandibular nociceptive inputs can influence the increase in asymmetry of the activation of this muscle.

Background Temporomandibular disorder (TMD) development in fibromyalgia syndrome (FMS) is not yet fully understood, but altered neuromuscular control in FMS may play a role in triggering TMD. Objective The purpose of this study was to verify the association between neuromuscular control and chronic facial pain in groups of patients with FMS and TMD. Design A cross-sectional study was conducted. Methods This study involved an analysis of facial pain and electromyographic activity of the masticatory muscles in patients with FMS (n=27) and TMD (n=28). All participants were evaluated according to Research Diagnostic Criteria for Temporomandibular Disorders and surface electromyography (SEMG). Myoelectric signal calculations were performed using the root mean square and median frequency of signals. Results The data revealed premature interruption of masticatory muscle contraction in both patient groups, but a significant correlation also was found between higher median frequency values and increased facial pain. This correlation probably was related to FMS because it was not found in patients with TMD only. Facial pain and increased SEMG activity during mandibular rest also were positively correlated. Limitations Temporal conclusions cannot be drawn from the study. Also, the study lacked a comparison group of patients with FMS without TMD as well as a control group of individuals who were healthy. Conclusions Altered neuromuscular control in masticatory muscles may be correlated with perceived facial pain in patients with FMS.

Generalized Joint Hypermobility

Temporomandibular disorders (TMD) consist of a group of symptoms such as: pain of temporomandibular joints, masticatory muscles or surrounding tissues, dysfunctions of TMJs’ mobility, and crepitation. The Hypermobility Joint Syndrome (HJS) manifests in the flaccidity of joint structures, an increase in the range of joint motion, and occurs more often in the young and women. The aim of this study was to present the occurrence of HJS among patients with myogenic TMD and disc displacement with reduction. The secondary goal was to assess the effectiveness of physiotherapy directed to TMD with coexisting HJS. The study involved 322 patients with symptoms of TMD. HJS was diagnosed using the Beighton Scale, which confirmed its occurrence in 26 cases. 79 subjects (7 males and 72 females; mean age, 33.9 ± 10.4 years) were selected and divided into two groups: HJS + TMD (n = 26; 2 males and 24 females; mean age, 27.1 ± 9.4 years) and TMD (n = 53; 5 males and 48 females; mean age, 37.4 ± 9.2 years). These patients completed 3-week physiotherapy management. Before and after physiotherapy, the myofascial pain severity on Numeric Pain Rating Scale, linear measurement of maximum mouth opening, and opening pattern, were assessed. To demonstrate differences between the results, the level of significance for statistical analysis was set at α = 0.05. A statistically significant improvement was obtained in decreasing myofascial pain in both groups. Coordination of mandibular movements was achieved in both groups. Generalized joint hypermobility occurred among patients with TMD. Physiotherapy directed to TMD was effective in reducing myofascial pain and restoring TMJ’s coordination also in patients with HJS.

The Relationship

Considered as a set of disorders, temporomandibular disorder (TMD) involves several anatomical structures such as the temporomandibular joint, masticatory muscles and attached structures. Its etiology is multifactorial, and the psychobehavioral factor, especially sleep disorders, is relevant in this context. This study aimed to assess the prevalence of temporomandibular dysfunction (TMD), sleep quality, and possible associations between these variables, in first to fifth year students of the Dental School. A sample of 182 students participated in this study and a questionnaire proposed by the American Academy of Orofacial Pain and the Pittsburgh Sleep Quality Index questionnaire were used to obtain the data. 75.27% of the students were females and 24.72% males. TMD was observed in 45.60% of students, and 68.13% of the students reported poor sleep quality. However, there was no significant association between the variables (TMD and sleep quality, p=0.114). Regarding the severity of TMD, the mild form was more prevalent (34.61%), being more prevalent in females (79.16%). However, there was no significant association between TMD and sleep quality (p=0.317). There was no association between TMD and sleep quality in the studied population.
