Características miofuncionais orofaciais em adultos com disfunção temporomandibular crônica / Orofacial myofunctional characteristics in adults with chronic temporomandibular disorder

Objetivo: avaliar a condição miofuncional orofacial de indivíduos com disfunção temporomandibular, caracterizar o padrão de mastigação e investigar a relação entre a condição miofuncional orofacial e o desempenho nas funções de mastigação e deglutição. Materiais e métodos: foram analisados prontuários de participantes de um projeto de extensão interdisciplinar de odontologia e fonoaudiologia. A idade mínima para compor a amostra foi 18 anos. Os participantes haviam realizado exame odontológico e avaliação fonoaudiológica, com o protocolo de Avaliação Miofuncional Orofacial com Escores. Os resultados foram apresentados por distribuição absoluta,relativa e medidas de tendência central.Foram aplicados o teste t-student para amostras independentes e correlação de Pearson para avaliar associação. O nível de significância adotado foi 5%. As análises foram realizadas no IBM SPSS Statistics 21. Resultados: Dezessete prontuários integraram a amostra. A média de idade dos participantes foi 41,2 anos (±12,2),76,5% eram do sexo feminino. A média do escore total (AMIOFE) indicou condição miofuncional normal (92,5±5,14), porém da mastigação (7,94±1,60) e deglutição (13,1±1,17) revelam prejuízos funcionais. Não houve diferença significativa entre homens e mulheres no escore total (p=0,687), tampouco nas diferentes categorias avaliadas. Discussão:Os escores totais encontrados neste estudo, na mastigação e deglutição, estão de acordo com outras pesquisas realizadas e revelam alteração na função. Conclusão: as alterações funcionais orofaciais encontradas nos indivíduos com disfunção temporomandibular crônica deste estudo estão relacionadas com a condição miofuncional orofacial de uma maneira geral, e devem ser consideradas na elaboração de planos de tratamento, com o objetivo de proporcionar maior estabilidade aos resultados.

Aim: to evaluate the orofacial myofunctional condition of individuals with temporomandibular disorders, to characterize the mastication pattern and to investigate the relationship between the orofacial myofunctional condition and performance in mastication and swallowing functions. Materials and methods: medical records of participants in an interdisciplinary extension project in dentistry and speech therapy were analyzed. The minimum age to compose the sample was 18 years old. The participants had undergone a dental examination and speech-language pathology assessment, using the Orofacial Myofunctional Evaluation Protocol With Score protocol. Results were presented by absolute and relative distribution and measures of central tendency. Student's t-test for independent samples and Pearson's correlation were applied to assess association. The significance level adopted was 5%. Analyzes were performed using IBM SPSS Statistics 21. Results: seventeen medical records were part of the sample. The participants' mean age was 41.2 years (±12.2), 76.5% were female. The mean total score (OMES) indicated normal myofunctional condition (92.5±5.14), but mastication (7.94±1.60) and swallowing (13.1±1.17) revealed functional impairments. There was no significant difference between men and women in the total score (p=0.687), nor in the different categories evaluated. Discussion: The total scores found in this study, in mastication and swallowing, are in agreement with other studies carried out and reveal changes in function. Conclusion: functional variations found in subjects with chronic temporomandibular joint dysfunction in this study are related to general myofunctional orofacial disorder, and must be taken into consideration in treatment plans, with the aim of granting stability to the results.

Impacto das medidas de distanciamento social relacionadas à covid-19 em pacientes com disfunção temporomandibular / Impact of social distancing related to COVID-19 in patients with temporomandibular disorder

Aim: To evaluate the impact of the social distancing imposed by COVID-19 in the socioeconomic, familiar and health scope of the participants, as well as the relation of the gravity of the sign and symptoms of Temporomandibular disorder. Materials and methods: Two questionnaires were applied, one by telephone interview and the other virtual. The first asked about signs and symptoms of temporomandibular disorder and the second about behavior during the pandemic. Results: The sample was composed by 15 patients, mostly women who lived in Porto Alegre. 64,3% of the subjects declared there was a decrease in household income during this period. Concerning to difficulties found to access health service, make an appointment, and get health care, were the most cited, each pointed to 61,5% of the sample. The presence of anxiety and depression feelings were cited 64,3%. There was an increase in alcohol consumption during the pandemic as a decrease in the frequency of physical activity. Discussion: Several studies that were conducted during and after the pandemic, corroborate the findings that the social distancing cause negative repercussions in the mental health, socioeconomics situations and in the daily habits in the population from all over the world. Conclusion: With this study we could observed and analyzed how the patients who suffered with TMD faced the challenges proposed by the social distancing, due to COVID-19. We can conclude that the pandemic causes several negatives effects in most of the group.

Non-invasive therapies for management of temporomandibular disorders: a systematic review

Introduction: As a multifactorial disease, temporomandibular disorders (TMD) require a complex therapeutic approach, being noninvasive therapies the first option for most patients. The aim of this study was to perform a systematic review to analyze the most common non-invasive therapies used for TMD management. Methods: The review was done by searching electronic databases to identify controlled clinical trials related to pharmacologic and non-invasive treatments. Of all potential articles found, 35 were included in this review. Results: Low-level laser therapy (LLLT), occlusal splints (OS) and oral exercises/ behavior education (OE/BE) were the most common therapies used. LLLT showed significant results in pain and movement improvement in most studies. OS was usually combined to other therapies and resulted in improvement of pain. OE/BE showed significant results when combined with ultrasound, LLLT, and manual therapy. Conclusions: Non-invasive treatments can provide pain relief and should be prescribed before surgical procedures. LLLT was the therapy with the higher number of studies showing positive results. Based in heterogeneity of treatment protocols, diagnostic and outcomes criteria used, new well-designed randomized controlled trials (RCT) are necessary. (AU)

Comparative effectiveness of photobiomodulation and manual therapy alone or combined in TMD patients: a randomized clinical trial.

The effectiveness of photobiomodulation (PBM) and manual therapy (MT), alone or combined (CT), were evaluated in pain intensity, mandibular movements, psychosocial aspects, and anxiety symptoms of temporomandibular disorder (TMD) patients. Fifty-one TMD patients were randomly assigned to three groups: the PBM group (n = 18), which received PBM with 808 nm, 100 mW, 13.3 J/cm2, and 4 J per point; the MT group (n=16) for 21 minutes each session on masticatory muscles and temporomandibular joint TMJ; and the CT group (n = 17), applied during twelve sessions. Seven evaluations were performed in different moments using visual analogue scale (VAS), Research Diagnosis Criteria for Temporomandibular Disorders (RDC/TMD) Axis I and II, and Beck anxiety inventory (BAI). All groups demonstrated reductions in pain and improvement in jaw movements during treatment and at follow-up (< 0.001). The assessment of psychosocial aspects of TMD, comparing baseline and follow-up in all treatment groups, revealed that treatment did not promote modification in the intensity of chronic pain (p > 0.05). However, depression symptoms showed a reduction in PBM and CT groups (p≤0.05). All treatments promoted reduction in physical symptoms with and without pain and enhancement of jaw disabilities (p ≤ 0.05). MT promotes improvement in 5 functions, PBM in 2, and CT in 1 (p < 0.001). BAI analysis revealed that all treatments lead to a reduction in anxiety symptoms (p≤0.05). All protocols tested were able to promote pain relief, improve mandibular function, and reduce the negative psychosocial aspects and levels of anxiety in TMD patients. However, the combination of PBM and MT did not promote an increase in the effectiveness of both therapies alone.

Influence of the patient's clinical information on the diagnostic reproducibility and accuracy of MRI scans of temporomandibular joint pathologies.

PURPOSE: To evaluate the influence of the patient's clinical information on the accuracy as well as interexaminer and intraexaminer reproducibilities of temporomandibular joint (TMJ) magnetic resonance imaging (MRI) scans. MATERIALS AND METHODS: Forty MRI scans from 20 TMJs corresponding to 7 TMJ pathologies (ie, degenerative alterations of the condyle, degenerative alterations of the mandibular fossa, alterations in the morphology of the TMJ disc, disc displacement with reduction, disc displacement without reduction, TMJ effusion, and TMJ hypermobility) were assessed by seven uncalibrated specialists in temporomandibular disorders (TMD) at baseline, 30 day-, and 60-day follow-ups for accuracy and reproducibility. No clinical information was provided before the 60-day follow up. RESULTS: Examiners had a poor to regular accuracy (0.10 to 0.36), kappa index and 5% to 60% correct positive diagnosis) when compared with the radiologist's diagnoses (gold standard). The interexaminer reproducibility ranged from moderate to substantial (kappa = 0.32 to 0.71), and the intraexaminer reproducibility ranged from moderate to perfect (kappa = 0.38 to 1.00). Provision of clinical information improved neither the accuracy nor the reproducibility of the results (P < .05), with the exception of the intraexaminer reproducibility of one examiner. CONCLUSIONS: Calibration is needed in assessing TMJ MRI scans, even when trained specialists are provided with clinical information from the patient.

Relationship between sounds and disc displacement of the temporomandibular joint using magnetic resonance imaging / Relação entre ruído e deslocamento de disco da articulação temporomandibular utilizando imagem de ressonância magnética

Purpose: Magnetic resonance imaging (MRI) is useful for interpreting temporomandibular joint (TMJ) disorders including disc displacement. This study aimed to evaluate the relationship between TMJ sounds and disc displacement with and without reduction by clinical examination and MRI. Methods: A sample of 58 patients was clinically examined when after being referred to MRI due to signs and symptoms of unilateral or bilateral TMJ disc displacement. The diagnosis obtained using MRI was compared with the clinical findings for the presence or absence of articular sounds. Results: Most patients (n=39; 67%) had joint sounds manifested as clicking; the other 19 patients (33%) did not present sounds. Among the 39 patients with sounds, bilateral clicking was observed in 29 (74%), and unilateral clicking in 10 (26%) patients. Unilateral clicking was equally observed on the right and left sides, each occurring in 5 five patients (13%). Conclusion: The results suggest that articular sounds do not occur exclusively in TMJ with disc displacement with reduction. The presence or absence of joint sounds will not suffice as the only aspect criterion to be considered in the differential diagnosis of disc displacement with and without reduction.

Objetivo: A ressonância magnética nuclear (RMN) é de grande utilidade para o diagnóstico das desordens temporomandibulares, inclusive o deslocamento de disco é muito comum. O objetivo deste estudo foi avaliar a relação entre ruído articular e deslocamento de disco com e sem redução por meio de avaliação clinica e ressonância magnética nuclear. Metodologia: O estudo examinou 58 pacientes clinicamente, que foram submetidos à RMN quando apresentavam de sinais e sintomas de deslocamento de disco uni ou bilateral. O diagnóstico obtido pela RMN foi comparado com os achados clínicos relativos à presença ou não de ruído articular. Resultados: Dos 58 indivíduos estudados, 39 (67%) apresentaram ruído articular do tipo click, os restantes 19 (33%) não apresentaram ruídos. Dos 39 com ruído, a ocorrência bilateral foi de 29 (74%) e unilateral em 10 (26%) casos, sendo 5 (13%) do lado direito e 5 (13%) do lado esquerdo. Conclusão: Os resultados demonstraram que os ruídos articulares não estão restritos a articulações com deslocamento de disco com redução. A presença ou ausência de ruído articular não devem ser os únicos aspectos considerados para o diagnóstico diferencial entre deslocamento de disco com e sem redução.

Dor miofascial ou síndrome de Eagle? A importância do diagnóstico diferencial / Myofascial pain or Eagle´s syndrome? The importance of the differential diagnosis

A síndrome do processo estiloide alongado ou síndrome de Eagle e a dor miofascial fazem parte das disfunções craniomandibulares. Vários relatos de casos clínicos encontrados na literatura enfatizam as anormalidades do complexo estiloideo associadas a vários sintomas, como dor muscular, tender points, trigger points, que confundem o diagnóstico ou associam esses sintomas a outras enfermidades. Nesse sentido, é importante a obtenção de um diagnóstico preciso, em virtude de sintomatologia confundente. Este artigo relata um caso de dor miofascial no qual a paciente se apresentava com dor em região de cabeça e pescoço com o processo estiloide alongado em torno de 78 mm (observado em radiografia panorâmica). O diagnóstico final foi obtido por meio de exame clínico investigatório associado a imagens.

Avaliação da presença de edema ósseo intramedular, efusão e osteoartrose em ATMs com deslocamento de disco por meio da ressonância magnética nuclear / Evaluation of the presence of bone marrow edema, effusion and osteoarthrosis in TMJs with displacement disc by nuclear magnetic resonance

Considerando a importância da associação do diagnóstico por imagem ao exame clínico na avaliação de pacientes com disfunção temporomandibular, o objetivo da presente pesquisa foi investigar, por meio de exames por ressonância magnética nuclear, a relação do deslocamento de disco com o edema ósseo intramedular, a efusão articular e a osteoartrose da articulação temporomandibular. Para isso, foram avaliadas imagens de 65 ATMs de 37 pacientes adultos, de ambos os sexos com diagnóstico clínico de disfunção temporomandibular e radiográfico de deslocamento de disco. Os resultados mostraram a presença de osteoartrose em 26,3 por cento, efusão em 33,7 por cento e edema em 16,8 por cento dos casos. A osteoartrose esteve presente em 70,6 por cento das ATMs com deslocamento de disco sem redução e em apenas 12,5 por cento dos deslocamentos com redução. Além disso, não houve relação estatísticamente significativa entre o deslocamento anatômico do disco e as patologias. Essa variabilidade mostrou a importância do diagnóstico por RMN para o tratamento diferenciado de cada caso

Avaliação histoquímica e morfológica das alterações estruturais da matriz extracelular nos tecidos da região anterior da cabeça da mandíbuba da articulação temporomandibular de coelhos submetidos à interferência oclusal unilateral / Histochemical and morphological evaluation of the extracelular matrix of the anterior articular surface of temporomandibular joint condyle in rabbit with an occlusal interference

Neste estudo, foram avaliadas as alterações teciduais da cabeça da mandíbula da articulação temporomandibular de coelhos submetidos à interferência oclusal unilateral. Osanimais foram sacrificados 7, 30 e 60 dias após a colocação da interferência. As articulações foram retiradas em bloco e foram realizados cortes histológicos corados por hematoxilina-eosina, picrossirius-hematoxilina e alcian blue. Os resultados indicaram que os tecidos presentes na região anterior da superfície articular da cabeça da mandíbula foram afetados pelo aumento da dimensão vertical de oclusão. / Tissual changes were assessed in the condyle of the temporomandibular joint (TMJ) in rabbits submitted to an unilateral occlusal interference insertion. The animals were sacrificed after 7, 30, and 60 days of the placing of the interference appliance. Joints were removed en bloc. HE, Picrosirius-hematoxylin, and Alcian blue stained sections were prepared. The results indicate that the tissues of the anterior articular surface of the condyle are affected by the unilatreral bite raise. Cell proliferation, thickening of the joint tissue, fibrosis, and ossification were observed both contralaterally and on the same side the interference appliance was placed. Such processes may be interpreted as a morphological adaptation to the new functional demands on the TMJ as of the change in the occlusion pattern...
