Relevant Role

Temporomandibular disorder (TMD) encompasses a set of disorders involving the masticatory muscles, the temporomandibular joint and associated structures. It is a complex biopsychosocial disorder with several triggering, predisposing and perpetuating factors. In the etiology of TMD, oral parafunctions, namely bruxism, play a relevant role. The study of bruxism is complicated by some taxonomic and diagnostic aspects that have prevented achieving an acceptable standardization of diagnosis. The aim of this study was to analyze the prevalence of temporomandibular disorders and bruxism in a Portuguese sample.

High Prevalence

Despite nearly a century of research on diseases affecting the temporomandibular joint (TMJ), masticatory muscles and associated structures, this problem still remains open. Pain syndrome caused by TMJ diseases ranks first in terms of prevalence among non-odontogenic pain syn-dromes in the maxillofacial region and leads to a signifi-cant deterioration in the quality of life of patients. The high prevalence of these diseases in female patients and the presence of a number of factors of a somatic, psycho-logical and social nature, contributing to such a high prevalence, indicate the need for more close attention of researchers to these aspects, which can become a way to develop new effective methods for the diagnosis and treatment of TMJ diseases in this category of patients. A review of scientific literature was carried out in order to identify topical scientific issues related to the study, di-agnosis and treatment of TMJ diseases.

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.

Introduction: Temporomandibular disorders (TMD) are a common and invalidating disease sometimes difficult to treat. Current international recommendations favour reversible and non-invasive treatments, including the injection of botulinum toxin (BTX) into masticatory muscles. There is no strong evidence of its effectiveness. Objective: The main goal of this study was to assess the effectiveness of BTX six months following injection, in terms of pain, mouth opening, improvement of symptoms and duration of effect. Materials and methods: A retrospective study carried out at Nantes University Hospital between 2014 and 2016. Results: Thirty-four patients were included. The mean age was 37 years (17–76) and seventy six percents were female. Eighty percent of patients reported a significant improvement, notably in cases of arthralgia, which decreased in 8/18 (44%) patients (p < 0.05). The mean duration of measured efficacy was 4.2 months. Discussion: Significant improvement in cases of arthralgia and a tendency for improvement in cases of myalgia, with a mean duration of action of 4.2 months. Although BTX injection do not guarantee complete resolution of myofascial pain, it have been shown to have beneficial effects on some symptoms have been shown. Conclusion: Botulinum toxin should be considered as an alternative treatment when other conservative methods fail to yield satisfactory results. A thorough multicentre assessment is necessary in the future to scientifically validate its use.

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.

Background: Temporomandibular disorders (TMD) are disorders of multifactorial origin that affect the temporomandibular joint and/or masticatory muscles. The TMD can generate compensations where physical therapy acts through myofascial releases and joint mobilizations to restore functionality. Objective: To verify the effects of manual therapy techniques on pain and electromyographic activity (EMG) of masticatory muscles in TMD patients. Methods: This is a quasi-experimental study composed of 10 subjects with TMD and 10 healthy subjects who underwent a session of myofascial release, joint mobilization and digit-pressure on the masticatory and cervical muscles. Pain levels and electromyographic activities of the temporal and masseter muscles were bilaterally assessed during the following situations: (1) Maximum Occlusion and (2) Chewing in the right and the left side with chewing gum. Data analysis was performed using BIOMEC-SAS software, in which the data were filtered with a 4th order Butterworth bandpass filter with 20-400hz and normalized as a percentage of maximum occlusion. Data were divided into homolateral and contralateral muscles alongside chewing. EMG variables were compared by factorial ANOVA, and pain by dependent t-test. Results: TMD patients had pain level reduction during maximum occlusion (Pre:4.55±2.2; Post:2.55±1.6; p=<0.001), right chewing (Pre:2.3±2.16; Post:0.4±0.69; p = 0.02) and left chewing (Pre: 1.0±1.15; Post:0.10±0.31; p = 0.05). There was no effect of manual therapy techniques on the EMG activity bilaterally of the temporal (p = 0.617) and masseter (p = 0.926) muscles during chewing. Patients with TMD had higher EMG activities during chewing on the homolateral temporal (p = 0.001) and masseter (0.004) muscles compared to subjects without injury. Conclusion: Manual therapy techniques reduced pain level in TMD patients. No changes in EMG activity were observed after manual therapy techniques. Finally, the study provides evidence of the influence of manual therapy techniques on short-term pain.

AbstractTemporomandibular disorders (TMD) affect the temporomandibular joints, the masticatory muscles, and surrounding tissues. Among symptoms such as jumps, joint noises, reduced mouth opening (closed lock), difficulties in closing the mouth (subluxation or open lock), pain is the most common symptom encountered among patients diagnosed with temporomandibular disorders. As literature on this topic is abundant and sometimes controversial, the authors focus on reviewing the state of art of occlusal splints indications. Therefore, the most common occlusal splints, like Lucia jig, nociceptive trigeminal inhibition (NTI), directive splints, etc., are being described, based on their design and therapeutic indications. Cases of malocclusions associated or not with parafunctions are usually manageable using the splints mentioned in this article. In case of disc displacements, occlusal appliances can be used, but as the etiology is multifactorial, there are some limitations, depending on the complexity of each clinical situation.

Temporomandibular disorders are complex dysfunctions of masticatory muscles and temporomandibular joints. Their symptoms affect more than 40% of the population and their prevalence is rising. It is important to establish a unified protocol for this specialistic examination. This review describes the authors’ own longstanding experiences and the discrepancies in the current literature regarding this topic as well as a detailed procedure of diagnosing temporomandibular disorders including the leading but often underrated role of a medical interview. We presented optimal physical examination methods as well as specific situations in which additional diagnostic and imaging tools may be useful. The emphasis was put on the importance of differential diagnosis between temporomandibular disorders and other diseases presenting with similar symptoms.
