ABSTRACT

A articulação temporomandibular está vunerável a várias condições de anormalidades já bastante conhecidas, dentre elas, o deslocamento do disco articular sem redução, considerado pela literatura o mais comum das patologias desta região. A deterioração do quadro pode ser um indicativo da necessidade cirúrgica. Em específico, no deslocamento de disco sem redução, o reposicionamento definitivo pode ser adquirido através de discopexia e artrocentese. O presente trabalho tem como objetivo relatar um caso clínico de deslocamento de disco articular bilateral sem redução, apresentando a importância da fisioterapia associada à abordagem cirúrgia na recuperação da função mandibular, bem como, reforçar a importância de uma abordagem conjunta entre análise clínica e imaginológica para resolução de casos. Paciente feminino cursando com diversos sintomas em face e pescoço de forma progressiva ao longo de dois anos foi submetida a cirurgia na articulação temporo-mandibular, onde foi feita a discopexia através de ancoragem dos discos articulares com parafusos. A avaliação física, assim como, a imaginológica, ajudaram na confirmação do diagnóstico. A abordagem cirurgica adotada no tratamento deste caso foi descrita na literatura desde o final do século XIX. Conclui-se que, o método utilizado no tratamento do deslocamento de disco sem redução deve ser baseado nos sinais e sintomas do paciente, cuja abordagem deve ser readequada de acordo com as mudanças do quadro apresentado. Nesta análise, a abordagem cirúrgica associada à fisioterapia específica para as estruturas musculoesquelética da face trouxeram resultados positivos(AU)


The temporomandibular joint is responsible for several well-known conditions of abnormalities, among them, the joint disc displacement without reduction, considered by the literature the most common pathology of this region. Deterioration of the condition may be indicative of surgical need. Specifically, in displacement disc without reduction, definitive repositioning can be achieved through discopexy and arthrocentesis. The aim of the present study is to report a case of unilateral articular disc displacement without reduction, as well the importance of physiotherapy associated with the surgical approach in the recovery of mandibular function, as well as reinforcing the importance of a joint approach between clinical and imaging analysis for case resolution. Female patient with several symptoms in the face and neck progressively over two years, underwent surgery in the temporomandibular joint, where discopexy was performed by anchoring the articular discs with screws. The physical assessment, as well as the imaging, helped to confirm the diagnosis. The surgical approach adopted in the treatment of this case has been described in the literature since the end of the 19th century. In conclusion, the method used to treat articular disc displacement without reduction should be based on the patient's signs and symptoms, whose approach should be readjusted according to the changes in the presented picture. In this analysis, the surgical approach associated with specific physiotherapy for the musculoskeletal structures of the face brought positive results(AU)

ABSTRACT

Introducción: la luxación de la articulación temporomandibular es un desplazamiento del cóndilo fuera de sus posiciones funcionales dentro de la fosa articular y la eminencia articular, la cual ocasiona una pérdida completa de la función articular. La luxación crónica es toda luxación aguda que progresa sin un tratamiento específico y que puede ser de carácter recurrente. La eminectomía es un tratamiento quirúrgico definitivo contra la luxación crónica de articulación temporomandibular. Objetivo: reportar el caso clínico de un paciente masculino, de la tercera década de su vida, con diagnóstico de luxación crónica de la articulación temporomandibular de cinco meses de evolución y presentar una revisión actualizada de la literatura sobre este procedimiento quirúrgico. Caso clínico: el paciente fue tratado quirúrgicamente con eminectomía bilateral. Discusión: la eminectomía es un procedimiento quirúrgico controversial; sin embargo, recientes investigaciones lo catalogan como seguro y efectivo. Conclusión: el caso clínico presentado muestra un buen resultado.

ABSTRACT

RESUMEN Introducción: Se denomina trastorno temporomandibular al conjunto de condiciones musculoesqueléticas que afectan la articulación temporomandibular, los músculos de la masticación y las estructuras anatómicas adyacentes. Objetivo: Evaluar la efectividad de las terapias físicas en pacientes con trastornos de la articulación temporomandibular. Métodos: Se efectuó una intervención terapéutica en la Clínica Estomatológica Provincial Docente Mártires del Moncada de Santiago de Cuba, desde junio de 2016 hasta febrero de 2020. La muestra quedó conformada por 264 pacientes distribuidos en 4 grupos con 66 integrantes cada uno, a quienes se les aplicaron diferentes terapias físicas, tales como ultrasonido, laserterapia, magnetoterapia y técnica de estimulación eléctrica transcutánea, respectivamente. Se analizaron las siguientes variables: edad, grado de trastorno de la articulación temporomandibular y efectividad terapéutica. Se empleó el porcentaje como medida de resumen y el estadígrafo de Ji al cuadrado con un nivel de significación de 0,05. Resultados: Predominó el sexo femenino en todas las terapias aplicadas con más de 75,0 % y el grupo etario de 40 - 49 años. Al finalizar el tratamiento se observó que en los grupos donde se empleó ultrasonido, láser y magneto, la respuesta fue efectiva en más de 90,0 % de los pacientes, con primacía del primero (96,6 %); sin embargo, en el grupo donde se utilizó la técnica de estimulación eléctrica transcutánea solo se logró en 89,4 % de los afectados. Conclusiones: La ultrasonoterapia fue más efectiva en pacientes con trastornos de la articulación temporomandibular.


ABSTRACT Introduction: A temporomandibular disorder is a group of musculoskeletal conditions that affect the temporomandibular joint, the mastication muscles and the adjacent anatomical structures. Objective: To evaluate the effectiveness of the physical therapies in patients with temporomandibular joint disorders. Methods: A therapeutic intervention was carried out in Mártires del Moncada Teaching Provincial Stomatological Clinic from Santiago de Cuba, from June, 2016 to February, 2020. The sample was formed by 264 patients distributed in 4 groups with 66 members each one, to whom different physical therapies were applied, such as ultrasound, laser therapy, magnetotherapy and technique of transcutaneous electric stimulation, respectively. The following variables were analyzed: age, grade of dysfunction of the temporomandibular joint and therapeutic effectiveness. The percentage as summary measure and the chi-squared test were used with a significance level of 0.05. Results: There was a prevalence of the female sex in all the therapies applied with more than 75.0 % and the 40 - 49 age group. When concluding the treatment it was observed that in the groups where ultrasound, laser and magneto was used, the response was effective in more than 90.0 % of the patients, with primacy of the first one (96.6 %); however, in the group where the technique of transcutaneous electric stimulation was used it was just achieved in 89.4 % of the affected patients. Conclusions: The ultrasonotherapy was more effective in patients with temporomandibular joint disorders.

ABSTRACT

Objetivo: Objetivou-se investigar as possíveis relações entre as Disfunções Temporomandibulares com alterações do Sistema Vestibular (SV). Métodos: Estudo descritivo com abordagem quantitativa realizado em 09 pacientes com idade média entre 18 e 40 anos. Os participantes foram recrutados no grupo de estudo e pesquisa em Fisioterapia e Odontologia na Dor Orofacial (FISIODOF) da Universidade de Fortaleza. O presente estudo foi aprovado pelo comitê de ética, com parecer N° 1.310.583. Resultados: De acordo com o RDC/TMD, 3 casos são do grupo G1, 1 caso é do grupo G2, 1 casos é do grupo G1 e G2, e os outros 4 casos como grupos G1 e G3. Todos os pacientes apresentaram resultados negativo no teste de Fukuda. Já na Manobra de Dix-Hallpike 3 pacientes apresentaram resultado positivo. Discussão: A hipertonia muscular é descrita como principal responsável pelos sintomas auditivos e vestibulares de pacientes com DTM. Entretanto, não existe uma relação precisa descrita na literatura entre DTM e disfunção do sistema vestibular. Conclusão: A DTM pode causar alterações no sistema vestibular, explicadas pelo fato das estruturas da articulação temporomandibular e sistema vestibular serem anatomicamente próximas. No entanto, outras pesquisas se fazem necessárias para caracterizar os achados vestibulares em portadores de disfunção temporomandibular(AU)


Objective: The objective was to investigate the possible relationships between Temporomandibular Disorders with changes in the Vestibular System (SV). Methods: Descriptive study with a quantitative approach conducted in 09 patients with a mean age between 18 and 40 years. Participants were recruited from the study and research group in Physiotherapy and Dentistry in Orofacial Pain at the University of Fortaleza. This study was approved by the ethics committee, No. 1,310,583. Results: According to the RDC / TMD, 3 cases are from the G1 group, 1 case is from the G2 group, 1 case are from the G1 and G2 group, and the 4 other cases are from the G1 and G3 groups. All patients had a negative Fukuda test result. In the Dix-Hallpike maneuver, 3 patients had a positive result. Discussion: Muscular hypertonia is described as the main responsible for the auditory and vestibular symptoms of patients with TMD. However, there is no precise relationship described in the literature between TMD and vestibular system dysfunction. Conclusion: TMD can cause changes in the vestibular system, explained by the fact that the structures of the temporomandibular joint and the vestibular system are anatomically close. However, further research is necessary to characterize vestibular findings in patients with temporomandibular disorders(AU)

ABSTRACT

El propósito de este trabajo cualtitativo fue aplicar el método de Bioneuroemoción en individuos que, estando en tratamiento por bruxismo, continuaban con dolor y sintomatología asociada. El análisis de las creencias limitantes en común de los individuos, las resonancias familiares y la emoción primaria desencadenada, permitieron obtener desde dónde percibían dichos individuos las situaciones de mayor estrés. Para ello, se consideró un diseño muestral centrado en un grupo de cinco pacientes que concurrían al Servicio de ATM (Articulación Temporomandibular) de un hospital odontológico de la Ciudad de Buenos Aires, donde estaban siendo tratados por bruxismo con placas miorrelajantes (AU)

ABSTRACT

RESUMO Objetivo comparar os conhecimentos e interesses dos fonoaudiólogos especialistas em motricidade orofacial quanto ao uso do laser de baixa potência antes e após a aprovação da Resolução nº 541 do Conselho Federal de Fonoaudiologia. Métodos trata-se de um estudo observacional, transversal e quantitativo, de caráter comparativo. Foi composto por dois momentos distintos: uma primeira coleta de dados, realizada em 2016, antes da aprovação da resolução e a segunda coleta, realizada em 2020, após a publicação das normativas. A primeira amostra foi constituída por 25 participantes e a segunda por 49, todos especialistas em motricidade orofacial. O instrumento de coleta consistiu em um formulário online elaborado no Google Forms, composto por questões do perfil do fonoaudiólogo, conhecimentos, interesses e aplicabilidades da fotobiomodulação com o laser de baixa potência. Os dados foram analisados utilizando estatística descritiva e inferencial. Resultados nos dois momentos, a expressiva maioria dos profissionais indicou saber o que é fotobiomodulação e concordou que o especialista em motricidade orofacial pode atuar com a técnica. Além disso, os profissionais apontaram a disfunção temporomandibular e a paralisia facial como principais casos para aplicações. Foram encontradas diferenças estatisticamente significativas entre os resultados obtidos antes e após a publicação da resolução, verificando-se aumento expressivo no acesso à bibliografia, capacitação, conhecimento das normas de biossegurança, acesso ao aparelho de laser e utilização na prática clínica. Conclusão constatou-se mudança no perfil profissional em relação ao uso da fotobiomodulação, com aumento dos conhecimentos, interesses e aplicabilidades pelos especialistas em motricidade orofacial, após a publicação da resolução normativa.

ABSTRACT

A mastigação pode ser realizada de maneira bilateral, porém a maioria das pessoas possui um lado de preferência mastigatório (LPM). O objetivo do estudo foi verificar, por meio de avaliação em imagens por tomografia computadorizada de feixe cônico (TCFC), se o LPM influencia em parâmetros anatômicos das ATM de indivíduos com disfunção temporomandibular (DTM) de origem articular. Para este estudo, 106 exames (212 ATM) de TCFC foram analisados, sendo 56 exames (112 ATM) de voluntários sem o diagnóstico de DTM (grupo controle - GC) e 50 exames (100 ATM) de indivíduos com diagnóstico de DTM de origem articular (grupo experimental - GE). As variáveis analisadas nos exames foram: o formato axial e o formato paracoronal das cabeças das mandíbulas (côndilos), o grau de translação e o grau de rotação articulares, o volume das cabeças das mandíbulas, a altura e a inclinação dos tubérculos articulares. Para estudar os fatores lado, LPM e grupo foram construídos, para cada variável analisada, quatro modelos de Equações de Estimação Generalizadas (EEG) e o nível de significância adotado foi de 5%. Apenas uma interação significante foi observada entre grupo e LPM para explicar o formato axial da cabeça da mandíbula (p-valor < 0,001). No entanto, dois tipos do formato axial foram excluídos do GE por não serem observados no LPM esquerdo, e após essa exclusão, o LPM não modificou a possibilidade de o paciente apresentar qualquer um dos outros três formatos axiais (p-valor > 0,05). Dessa forma, os resultados evidenciaram que o LPM não exerceu influência sobre os parâmetros estruturais e dinâmicos das ATM de indivíduos com DTM de origem articular. No entanto, estudos complementares são necessários para que nossos resultados possam ser replicados em amostras maiores.


Chewing can be done bilaterally, but most people have a chewing side preference (CSP). The objective of the study was to verify, through image evaluation using cone beam computed tomography (CBCT), if the CSP influences anatomical parameters of the TMJ of individuals with temporomandibular disorder (TMD) of joint origin. For this study, 106 exams (212 TMJ) of CBCT were analyzed, being 56 exams (112 TMJ) of volunteers without the diagnosis of TMD (control group - CG) and 50 exams (100 TMJ) of individuals diagnosed with TMD of origin articular (experimental group - EG). The variables analyzed in the exams were: the axial format and paracoronal format of the heads of the mandible (condyles), the degree of translation and the degree of articular rotation, the volume of the heads of the mandibles, the height and inclination of the articular tubercles. To study the side, CSP and group factors, four models of Generalized Estimating Equations (GEE) were built for each variable analyzed and the significance level adopted was 5%. Only one significant interaction was observed between group and CSP to explain the axial format of the head of mandible (p-value < 0.001). However, two types of axial format were excluded from the EG because they were not observed in the left CSP, and after this exclusion, the CSP did not change the possibility that the patient had any of the other three axial format (p-value > 0.05 ). Thus, the results showed that the CSP did not influence the structural and dynamic parameters of the TMJ of individuals with TMD of joint origin. However, further studies are needed so that our results can be replicated in larger samples.

ABSTRACT

A Disfunção Temporomandibular (DTM) é um grupo de desordens músculoesqueléticas que pode afetar os músculos da mastigação e as articulações temporomandibulares. Alguns critérios de diagnóstico vêm sendo propostos como o questionário Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), avaliação clínica cuidadosa, que em algumas situações deve ser complementada com exames de imagem, incluindo radiografias convencionais, tomografia computadorizada e ressonância magnética. Alternativamente, a termografia tem sido utilizada como um exame de imagem auxiliar no diagnóstico da DTM. Uma revisão sistemática das evidências existentes, em relação à eficácia do exame de termografia no diagnóstico das DTMs, foi feita para esclarecer a seguinte pergunta clínica "Qual a eficácia do exame termográfico no diagnóstico das DTMs em comparação à avaliação clínica?". A pesquisa foi realizada no Instituto de Ciência e Tecnologia (ICT) da Unesp, Brasil. Para isso foi traçada uma estratégia de busca nas seguintes bases de dados: PubMed, EMBASE, LILACS, Scopus, HTA DATABASE, Cochrane Library, Biblioteca Brasileira em Odontologia (BBO) e Web of Science. A busca foi registrada no PROSPERO - International Prospective Register of Systematic Reviews. Os títulos e resumos foram lidos e 86 artigos foram selecionados. Os textos completos foram lidos e a extração de dados foi realizada. A busca nas bases de dados resultou em 427 artigos, removidas as duplicatas restaram 234 artigos, e pela seleção de títulos e resumos 86 artigos foram selecionados para acesso ao texto completo. Os textos foram lidos e os dados relevantesforam extraídos. A avaliação da qualidade dos estudos incluídos foi realizada através da ferramenta QUADAS (Quality Assessment of Diagnostic Accuracy Studies) e os dados foram sintetizados de forma qualitativa, resultando em 11 artigos para extração de dados e avaliação de risco de viés. O exame de termografia pode ser considerado um exame auxiliar no diagnóstico das DTMs, porém mais estudos devem ser conduzidos.


Temporomandibular disorders (TMDs) are a group of painful musculoskeletal conditions that affect the masticatory muscles, the temporomandibular joints (TMJs), and/or other anatomic structures of the stomatognathic system. Standardized criteria for TMD diagnosis have been proposed (Diagnostic Criteria for Temporomandibular Disorders [DC/TMD]), and rely on careful clinical examination that is aided, in some situations, by imaging studies, including conventional radiography, computed tomography (CT) and magnetic resonance imaging (MRI). Alternatively, thermography has been presented as an auxiliary diagnostic test for assessing internal derangements of the TMJs because it is useful for TMD evaluation as a clinical screening method that improves diagnostic accuracy. A Systematic review of diagnostic accuracy studies and a critical synthesis of available evidence of thermography value in the diagnosis of TMD, was done in order to answer the question: "How effective is the thermographic examination in diagnosing TMD compared to clinical evaluation?" The research was hold in the Science and Technology Institute (ICT) Unesp, Brazil. A search strategy was drawn up in the following electronic databases: PubMed, EMBASE, LILACS, Scopus, HTA DATABASE, Cochrane Library, Brazilian Dentistry Library and Web of Science. The search was registered in the PROSPERO - International Prospective Register of Systematic Reviews. The titles and abstracts were read and 86 papers were selected. After full text analysis, the data extraction was performed. The online search identified a total of 427 papers, duplicate references were removed and 234 papers remained, and by selecting titles and abstracts 86 papers were selected for full text access. The QUADAS (Quality Assessment of DiagnosticAccuracy Studies) tool was used to assess the risk of bias, and the data were synthesized in a qualitative way. Resulting in 11 studies to extraction data and risk bias analysis. Although, the thermography can be considered an auxiliary diagnostic test, more studies must be conducted.

ABSTRACT

Abstract The present cross-sectional case-control study aimed to determine if there is an association between specific oral behaviors, sleep bruxism (SB), awake bruxism (AB), and painful temporomandibular joint (TMJ) clicking. Ninety individuals were dived into three groups; Group 1 (n = 30): painful TMJ clicking; Group 2 (n = 30): painless TMJ clicking; and Group 3 (n = 30): control group. The following clinical data were studied: oral behaviors (unilateral chewing, gum chewing, nail biting, foreign objects biting, leaning with jaw against the hand, and sleeping in a position that pressures the jaw), SB, AB (including the frequency in 10 days, evaluated by ecological momentary assessment), and malocclusions investigated based on clinical inspections (anterior open bite, posterior cross-bite, abnormal overbite/overjet, occlusal guidance, mediotrusive and/or laterotrusive interferences, retruded contact position to maximum intercuspation slide, missing posterior teeth). All statistical tests (Kolmogorov-Smirnov, chi-square, and one-way ANOVA) were performed with a 5% significance level. Group 1 had the highest frequency of and a significant association with leaning with jaw in the hand, sleeping position that pressures the jaw, gum chewing, nail biting, and AB (p<0.05). Gum chewing, nail biting, and AB were associated with Group 2 only when compared to Group 3 (p<0.05). No significant difference among groups was found for other behaviors (unilateral chewing and foreign objects biting), SB, and all malocclusions (p>0.05). It can be concluded that patients with painful TMJ clicking had a higher frequency of and a significant association with some specific harmful behaviors and AB.

ABSTRACT

RESUMO Objetivo Investigar a influência da fotobiomodulação associada à terapia miofuncional orofacial (TMO) em pacientes com disfunção temporomandibular muscular (DTM). Método Trata-se de uma pesquisa do tipo ensaio-clínico randomizado e cego, com uma amostra de 11 mulheres com DTM muscular, dividida em dois grupos. O Grupo Experimental (GE) composto por 05 voluntárias submetidas à TMO associada à fotobiomodulação, e o Grupo Controle Positivo (GC) composto por 06 mulheres submetidas à TMO associada à fotobimodulação inativa (placebo). A intervenção foi realizada em 12 sessões: uma avaliação, 10 sessões de fonoterapia associada à fotobiomodulação, e uma reavaliação. Para os desfechos foram consideradas a investigação da percepção de dor, com a Escala Visual Analógica (EVA), a investigação da sensibilidade à palpação com o protocolo Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), e a verificação da qualidade de vida (QV) por meio do protocolo Oral Health Impact Profle - short form (OHIP-14). Resultados o GE teve aumento nas medidas dos movimentos de abertura e de protrusão mandibular, e evidenciou melhora na avaliação da QV. Conclusão A TMO quando associada à fotobiomodulação contribuiu no aumento da amplitude dos movimentos mandibulares e com ganhos importantes na percepção da qualidade de vida, e com melhora significativa nos quadros dolorosos das voluntárias com DTM.


ABSTRACT Purpose To investigate the influence of photobiomodulation associated with orofacial myofunctional therapy (OMT) in patients with temporomandibular muscle disorders (TMD). Methods Randomized, blinded trial clinical study with a sample of eleven women with muscle TMD divided into two groups. The experimental group (EG) consisted of five women submitted to orofacial myofunctional therapy associated with photobiomodulation, and the control group (CG) consisted of six women submitted to orofacial myofunctional therapy associated with inactive photobiomodulation (placebo). The intervention was performed in the following twelve sessions: one evaluation, ten speech therapy sessions associated with photobiomodulation, and one reevaluation. For outcomes, investigation on pain perception using the visual analogue scale (VAS), investigation of palpation sensitivity with the research diagnostic criteria for temporomandibular disorders (RDC/TMD), and quality of life (QOL) verification through oral health impact profile - short form (OHIP-14) were considered. Results The EG increased measurements of mandibular movements of opening and protrusion and improved in the evaluation of QOL. Conclusion Orofacial myofunctional therapy, when associated with photobiomodulation, contributed to increase the range of mandibular movements, with important improvements in the perception of quality of life and with significant improvement in the painful conditions of volunteers with TMD.

ABSTRACT

ABSTRACT Purpose The aim of the study was to investigate the electroneurophysiological aspects of volunteers with temporomandibular disorders before and after performing isotonic exercises for pain relief and self-care guidelines. Methods The study was a parallel controlled randomized controlled trial under protocol 1,680,920. The inclusion criteria were age between 18 and 60 years, muscle temporomandibular dysfunction with or without limitation of mouth opening and self-reported pain with scores between 4 and 10. The individuals were randomized into experimental group and control. Twenty-three volunteers participated in the study, most of then were female. Control group had 11 and experimental group 12 individuals. Dropouts occurred in both groups, two in the experimental group and three in the control group. Since there were an intergroup imbalance the power density was analysed just in experimental group. Electroencephalographic recording was performed before and after the interventions, using the 32-channel apparatus, with sample frequency of 600 Hz and impedance of 5 kΩ. The data were processed through the MATLAB computer program. The individual records filtered off-line, using bandpass between 0.5 and 50 Hz. Epochs of 1,710 ms were created and the calculation of the absolute power density calculated by means of the fast Fourier transform. The statistical approach was inferential and quantitative. Results The alpha power density analyzed presented a difference, but not significant, when compared in the two moments. Conclusion According to this study, isotonic exercises performed to reduce pain provided a small increase in alpha power density in the left temporal, parietal and occipital regions.

ABSTRACT

Abstract Mirror-image pain is a kind of pain that occurs on the contralateral side, but its pathogenesis remains unclear. Objective To develop an osteoarthritis mouse model for investigating mirror-image pain through observing nocifensive behaviors, histological changes, and nociceptive activity at days 3, 7, 14, 21, and 28 after the chemical induction of unilateral temporomandibular joint (TMJ) osteoarthritis. Methodology We randomly divided 6-week-old mice into sham and complete Freund adjuvant groups. To induce nocifensive behaviors, we applied 0.04 g of von Frey filament, 10 psi of air puff, and cold acetone on both sides of whisker pads at different days. The histology of TMJ on both sides was observed by hematoxylin/eosin staining and microcomputed tomography scanning. Furthermore, the nociceptive activity was evaluated using the phosphorylated cyclic AMP response element binding protein (pCREB) and a microglia marker at different days in the trigeminal subnucleus caudalis. Results Nocifensive behaviors against mechanical and temperature stimuli on the contralateral side became stronger than the baseline on day 28, in agreement with the elevation of the pCREB and the microglia marker in the trigeminal subnucleus caudalis. Thus, hypernociception on the contralateral side occurred at day 28. Conclusions Clearly, the TMJ model with unilateral osteoarthritis exhibited mirror-image pain. Therefore, this model is useful in investigating the pathogenesis of pain and in developing treatments.

ABSTRACT

Resumen El objetivo del estudio fue analizar si la hiperlaxitud articular generalizada (HAG) es un factor de riesgo para los trastornos de la articulación temporomandibular (ATM). Para ello se evaluó la posible asociación entre chasquido de la ATM y el diagnóstico de HAG. Se trabajó con la siguiente hipótesis: el paciente con HAG, tendría mayor prevalencia de chasquido a nivel de la ATM que los que no la presentan, constituyendo la HAG un factor de riesgo para padecer un desorden articular (DA). Se examinaron 214 estudiantes de facultad de odontología (FO) de la Universidad de la República (Udelar) de Uruguay, 161 participantes del sexo femenino y 53 masculino, de entre 18 y 30 años (edad media 23.8 años, DE=2.7). A cada participante se le realizó un cuestionario y un examen clínico para diagnóstico de HAG utilizando el índice de Beighton (IB), chasquido, antecedente de trauma maxilofacial, ortodoncia, dentición completa, bloqueo abierto y turno. Todos los exámenes fueron realizados por un investigador ciego calibrado (calibración interoperador chasquido kappa= 0.68; intraoperador Beighton=0.82, chasquido=1). El estudio fue aprobado por el Comité de Ética y todos los participantes firmaron un consentimiento informado. El análisis estadístico de los datos fue realizado en base a un modelo de regresión logística múltiple. La prevalencia de HAG fue 34.16% en el género femenino y 7.55% en el masculino, de chasquido 24.22% para el femenino y 11.32% en el masculino. Las variables género (OR=3,244, p-valor 0,018) y antecedente de traumatismo (OR=2,478, p-valor 0,041) se asociaron significativamente a la presencia de chasquido. No se encontró asociación entre chasquido e HAG. El género femenino y los antecedentes de traumatismo podrían ser factores de riesgo para desórdenes a nivel de la ATM. La ausencia de asociación entre HAG y chasquido en dicho grupo etario (18-30 años), sugiere que dicho factor podría no ser de riesgo para el desarrollo de dichas patologías.


Resumo O objetivo do estudo foi examinar se a hiperlaxidade articular generalizada (HAG) é um fator de risco para disfuncao articulacao temporomandibular (DAT). Isso foi feito avaliando a possível associação entre cliques atm e diagnóstico hag. O trabalho foi feito com a seguinte hipótese: o paciente com HAG, teria maior prevalência de clique no nível atm do que aqueles que não o fazem, tornando a HAG um fator de risco para DAT. Foram examinados 214 alunos de Odontologia da Universidad de la República (Udelar) do Uruguai, 161 do sexo feminino e 53 do sexo masculino, com idade entre 18 e 30 anos (idade média de 23,8 anos, DE:2,7). Cada participante recebeu questionário e exame clínico para diagnóstico de HAG utilizando o índice Beighton (IB), clique, antecedente de trauma maxilofacial, ortodontia, dentição completa, bloqueio aberto e turno. Todos os testes foram realizados por um pesquisador cego calibrado (calibração interoperadora kappa-click-0,68; intraoperador Beighton-0.82, clique-1). O estudo foi aprovado pelo Comitê de Ética e todos os participantes assinaram consentimento informado. A análise estatística dos dados foi realizada com base em um modelo de regressão logística múltipla. A prevalência de HAG foi de 34,16% no sexo feminino e 7,55% no masculino, de clique 24,22% para o feminino e 11,32% para o masculino. As variáveis de gênero (OR-3.244, valor p 0,018) e antecedente do trauma (OR-2.478, valor p 0,041) estiveram significativamente associadas à presença de clique. Não foi encontrada associação entre clique e HAG. O sexo feminino e o histórico de trauma podem ser fatores de risco para distúrbios no nível do articulacao temporomandibular . A ausência de associação entre HAG e click sugere que esse fator pode não estar em risco para o desenvolvimento de tais patologias.


Abstract This study analyzes whether generalized joint hypermobility (GJH) is a risk factor for temporomandibular joint disorders (TMD). Therefore, we evaluated the potential association between TMD clicking and GJH diagnosis. We worked with the following hypothesis: patients with GJH would have a higher prevalence of TMJ clicking than those without it, making GJH a risk factor for joint disorders. Two hundred and fourteen students from the School of Dentistry of Universidad de la República del Uruguay (UdelaR) were examined: 161 female and 53 male, aged 18 to 30 (average age: 23.8 years, SD=2.7). Each participant was given a questionnaire, and a clinical examination was performed to diagnose GJH using the Beighton score (BS), clicking, history of maxillofacial trauma, orthodontics, full dentition, open lock, and shift. A calibrated blind researcher (kappa inter-rater click calibration = 0.68; intra-rater BS score=0.82, click=1) performed all the examinations. The Ethics Committee approved the study, and all the participants signed an informed consent. A multiple logistic regression model was used to analyze the data statistically. GJH prevalence was 34.16% in women and 7.55% in men; clicking prevalence was 24.22% in women and 11.32% in men. There was a significant association between sex (OR=3.244, p-value 0.018) and history of trauma (OR=2.478, p-value 0.041) and the presence of clicking. No association was found between clicking and GJH. Female sex and history of trauma could be risk factors for TMJ disorders. The lack of association between GJH and clicking in this age group (18-30) suggests that GJH may not be a risk factor for developing these pathologies.

ABSTRACT

Objetive: This study was to compare the effectiveness of arthrocentesis versus the insertion of anterior repositioning splint (ARS) in improving the mandibular range of motion (MRM) for patients with the temporomandibular joint (TMJ) anterior disc displacement with reduction (ADDwR). Methods: 36 patients diagnosed as ADDwR were recruited and divided randomly into two groups. The first group (G1) was treated by arthrocentesis, and the second (G2) was treated using ARS. All patients were reexamined after six months. Results: Except that for protrusive movement, there were significant differences between the two groups for the percentage changes of the MRM as measured by the amount of pain free opening, unassisted opening, maximum assisted opening, right lateral and left lateral movements (p < 0.05). Conclusion: Within the context of the current study, the non-invasive, lower cost ARS, provided better results in improving the MRM when managing ADDwR cases. (AU)


Objetivo: O presente estudo comparou a eficácia da Artrocentese em relação à inserção da Placa Reposicionadora Anterior (PRA) na melhoria da Amplitude de Movimento Mandibular (AMM) para pacientes que apresentam Deslocamento de Disco Anterior com Redução (DDAcR) da Articulação Temporomandibular (ATM). Método: 36 pacientes diagnosticados como DDAcR foram recrutados e divididos aleatoriamente em dois grupos. O primeiro grupo (G1) foi tratado através da Artrocentese e o segundo (G2), tratado com a PRA. Todos os pacientes foram reexaminados após seis meses. Resultados: Com exceção do movimento protrusivo, houve diferenças significativas entre os dois grupos para as mudanças percentuais das medidas de AMM pela quantidade de abertura sem dor, abertura sem assistência, abertura máxima com assistência, movimentos laterais direitos e laterais esquerdos (p < 0,05). Conclusão: Dentro do contexto do estudo atual, a PRA, não invasiva e de menor custo, proporcionou melhores resultados na melhoria da AMM no gerenciamento de casos de DDAcR (AU)

ABSTRACT

Temporomandibular joint osteoarthritis (TMJOA) is mainly manifested as perforation of temporomandibular joint disc (TMJD) and destruction of condylar osteochondral complex (COCC). In recent years, tissue engineering technology has become one of the effective strategies in repairing this damage. With the development of scaffold material technology, composite scaffolds have become an important means to optimize the performance of scaffolds with the combined advantages of natural materials and synthetic materials. The gelling method with the minimally invasive concept can greatly solve the problems of surgical trauma and material anastomosis, which is beneficial to the clinical transformation of temporomandibular joint tissue engineering. Extracellular matrix scaffolds technology can solve the problem of scaffold source and maximize the simulation of the extracellular environment, which provides an important means for the transformation of temporo joint tissue engineering to animal level. Due to the limitation of the source and amplification of costal chondrocytes, the use of mesenchymal stem cells from different sources has been widely used for temporomandibular joint tissue engineering. The fibrochondral stem cells isolated from surface layer of articular cartilage may provide one more suitable cell source. Transforming growth factor β superfamily, due to its osteochondrogenesis activity has been widely used in tissue engineering, and platelet-rich derivative as a convenient preparation of compound biological factor, gradually get used in temporomandibular joint tissue engineering. With the deepening of research on extracellular microenvironment and mechanical stimulation, mesenchymal stem cells, exosomes and stress stimulation are increasingly being used to regulate the extracellular microenvironment. In the future, the combination of complex bioactive factors and certain stress stimulation may become a trend in the temporomandibular joint tissue engineering research. In this article, the progress on tissue engineering in repairing COCC and TMJD, especially in scaffold materials, seed cells and bioactive factors, are reviewed, so as to provide information for future research design and clinical intervention.

ABSTRACT

OBJECTIVES@#To evaluate the value of arthroscopy in the diagnosis and treatment of synovial chondromatosis of the temporomandibular joint (TMJSC).@*METHODS@#The cases of 16 patients preliminarily diagnosed with TMJSC by magnetic resonance imaging (MRI) from July 2011 to December 2018 were analyzed retrospectively. If the diagnosis was confirmed by arthroscopy, the opening operation was performed. The preoperative MRI, arthroscopy and opening operation, postoperative pathology and postoperative MRI of confirmed cases were analyzed, and clinical follow-up was performed to evaluate the curative effect of open surgery. The degree of mouth opening and visual analogue scale (VAS) scores for pain pre-operation and during follow-up of the confirmed cases were analyzed by @*RESULTS@#Fourteen cases of TMJSC were diagnosed by arthroscopy, consistent with the postoperative pathological diagnosis. Postoperative MRI examination showed that articular cavity lesions basically disappeared. Ten patients with synovial chondromatosis were followed-up (follow-up rate, 71.4%) from 6 months to 7 years and 8 months (average follow-up time, 17.6 months); no recurrence was found, and clinical symptoms improved by varying degrees. Before operation and at follow-up, @*CONCLUSIONS@#Arthroscopy is essential in the diagnosis and treatment of TMJ synovial chondromatosis.

ABSTRACT

OBJECTIVES@#To investigate the differences in the temporomandibular joints (TMJs) between patients with anterior disc displacement with reduction (ADDwR) and asymptomatic subjects by using 3D morphometric measurements.@*METHODS@#A total of 15 patients with ADDwR and 10 asymptomatic subjects were enrolled. Then, 3D models of the maxilla and mandible were reconstructed using MIMICS 20.0. Nine morphologic parameters of TMJs on both sides were measured on the 3D solid model. The differences in the parameters were analyzed between the patients and the asymptomatic subjects and between the left and right sides of each group.@*RESULTS@#The horizontal and coronal condylar angles on the ipsilateral side of the patients were significantly greater than those of the asymptomatic subjects (@*CONCLUSIONS@#ADDwR will increase the condylar angles to be significantly greater than the normal level and decrease SRA and articular spaces to be significantly smaller than the normal level. The condyles will be displaced upward, closer to the fossa.

ABSTRACT

OBJECTIVES@#This study aimed to explore the role of osteoclast differentiation in the occurrence of temporomandibular joint osteoarthritis (TMJOA).@*METHODS@#A mouse TMJOA model was constructed. Micro-CT was used to observe the changes in condylar bone during the development of TMJOA. Hematoxylin-eosin (HE) staining was used to observe the histological structure changes of the condyle of TMJOA mice. Tartrate resistant acid phosphatase (TRAP) staining was used to observe the presence of osteoclasts in TMJOA joint tissue. The synovial fluid of patients with TMJ-OA was collected to determine the effect on osteoclast differentiation.@*RESULTS@#Micro-CT revealed that the condyle of the TMJOA group had the most obvious damage in the second and third weeks, and the shape of the condyles also changed in a beak-like manner. HE staining showed that the condyle cartilage and subchondral bone structure of TMJOA mice were disordered in the second week. TRAP tissue staining showed that the number of osteoclasts of the TMJOA group obviously increased in the second week. Results of cell experiments showed that the number of osteoclast differentiation significantly increased after stimulation of synovial fluid from TMJOA patients, and the cell volume increased.@*CONCLUSIONS@#TMJOA animal models and TMJOA patient synovial cell experiments could induce osteoclast differentiation, indicating that osteoclast differentiation plays an important role in TMJOA occurrence.
