Potential Biomarkers

Temporomandibular disorder is a disorder that includes masticatory muscles or temporomandibular joints, unbalanced joint function or both. The disorders can disturb daily activity, cause by pain. The therapy consuming time and cost. Early detection of temporomandibular disorder is needed, as a prevention of more severe disorders. Increased cortisol can be found in myofacial pain and is not found in internal dearagement or osteoarthritis. Biomarkers of interleukin and monocyte chemoattractant proteins are only found in osteoarthritis. The use of biomarkers can be useful in detecting temporomandibular disorders. Biomarkers can be measured from blood, serum and saliva. Cortisol, dopamine and TAC are potential biomarkers in the temporomandibular disorder.

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.

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.

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.

State Of Art

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.

Thermal Changes

Temporomandibular disorders (TMD) consist of a group of pathologies that affect the masticatory muscles, temporomandibular joints (TMJ), and/or related structures. String instrumentalists, like many orchestra musicians, can spend hours with head postures that may influence the biomechanical behavior of the TMJ and the muscles of the craniocervicomandibular complex (CCMC). The adoption of abnormal postures acquired during performance by musicians can lead to muscular hyperactivity of the head and cervical muscles, with the possible appearance of TMD. Medical infrared thermography is a non-invasive procedure that can monitor the changes in the superficial tissue related to blood circulation and may serve as a complement to the clinical examination. The objective of this study was to use infrared thermography to evaluate, in one subject, the cutaneous thermal changes adjacent to the CCMC that occur before, during, and after playing a string instrument.

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 and aims. Vitamin D is synthesized in the skin with the aid of ultraviolet-B radiation, playing a variety of roles in the body. Temporomandibular disorders (TMDs) are a group of pathological conditions involving the temporomandibular joints as well as the masticatory muscles and othersurrounding tissues. In the present narrative review, we investigated the potential role of vitamin D in the etiology of temporomandibular disorders in order todetermine whether the current knowledge supports 25-hidroxyvitamin D (25-OHD) supplementation in temporomandibular disorders associated with insufficient or deficient levels of vitamin D. Methods. A literature research was performed in PubMed, Scopus, Science Direct, and Google Scholar databases, and a total of 10 articles were included for analysis. Results.Among the observational studies published to date, investigating the role for vitamin D in the etiology of TMDs, six of them suggest that there is a connection between the two aspects. In this context, patients suffering from TMD, with deficient levels of vitamin D (<30 ng/mL), are most likely to benefit from supplementation, whereas individuals with vitamin D level >50ng/mL probably have little benefit from supplementation.Conclusion.Vitamin D might be a safe, simple, and potentially beneficial way to prevent TMDs or to reduce pain; however, more randomized and placebo-controlled trials are required before any firm conclusions can be drawn.

Introduction. Some clinicians believed that mandibular deviation leads to facial asymmetry and it also had a correlation with temporomandibular disorders (TMDs). Posteroanterior (PA) cephalogram was widely reported as a regular record in treating facial asymmetry and craniofacial anomalies. The objective of this study was to analyze the relationship of menton deviation in PA cephalogram with temporomandibular disorders (TMDs) symptoms. Materials and Methods. TMJ function was initially screened based on TMD-DI questionnaire. PA cephalogram of volunteer subjects with TMDs (n=37) and without TMDs (n=33) with mean age of 21.61±2.08 years was taken. The menton deviation was measured by the distance (mm) from menton point to midsagittal reference (MSR) horizontally, using software digitized measurement, and categorized as asymmetric if the value is greater than 3 mm. The prevalence and difference of menton deviation in both groups were evaluated by unpaired t-test. Result. The prevalence of symmetry group showed that 65.9% had no TMDs with mean of 1,815 ± 0,71 mm; in contrast, the prevalence of asymmetry group showed that 95.5% reported TMDs with mean of 3,159 ± 1,053 mm. There was a significant difference of menton deviation to TMDs (p=0.000) in subjects with and without TMDs. Conclusion. There was a significant relationship of menton deviation in PA cephalogram with TMDs based on TMD-DI index.
