ABSTRACT

Aim: To describe cone-beam computed tomography (CBCT) features in patients with temporomandibular disorders (TMDs), in terms of degenerative changes, condylar excursions and positioning as well as their possible correlations with signs and symptoms. Methods: Clinical records of patients diagnosed with TMD who were seen between January 2018 and December 2019 were retrospectively evaluated. These patients were divided into the following groups based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD): arthralgia, myalgia, and arthralgia and myalgia groups. The CBCT examination findings of the patients were evaluated in relation to degenerative changes, estimates of condylar excursion, and condylar positioning. The likelihood ratio test was used to verify the possible differences among the three groups, whereas the chi-square test was used to verify the possible differences among the signs and symptoms for the tomographic findings (p ≤ 0.050). Results: In this study, 65 patients with TMD were included. These patients were predominantly female (84.6%) with a mean age of 40.6 years. Tomographic findings of flattening, hyperexcursion and posterior condylar positioning were frequent. A significant correlation was noted between osteophyte and lateral capsule pain (p = 0.027), erosion and posterior capsule pain (p = 0.026), and flattening, pseudocysts (p < 0.050) and condylar excursion (p < 0.001) with mouth opening. Conclusion: Few correlations were noted between degenerative changes and signs of joint pain as well as degenerative changes and condylar hypoexcursion with mouth opening. These correlations were likely associated with division by diagnosis, whereas condylar positioning did not correlate with signs and symptoms

ABSTRACT

Los contactos mediotrusivos son aquellos contactos oclusales que se encuentran entre las vertientes in- ternas de las cúspides linguales maxilares y las inter- nas de las cúspides bucales mandibulares del lado de no trabajo durante los movimientos de lateralidad. Estos contactos mediotrusivos podría desencadenar trastornos temporomandibulares, afectando la oclu- sión y la articulación temporomandibular. El objetivo de este estudio es analizar las caracterís- ticas y la relación entre los contactos mediotrusivos con la articulación temporomandibular y la oclusión en pacientes que consultan al Servicio de Oclusión y ATM del Hospital Odontológico de la Facultad de Odontología de la Universidad Nacional del Nordeste (AU)


Mediotrusive contacts are those occlusal contacts that are found between the internal slopes of the maxillary lingual cusps and the internal slopes of the mandibular buccal cusps on the non-working side during laterality movements. These mediotrusive contacts could trigger temporomandibular disorders affecting occlusion and temporomandibular joint. The objective of this study was to analyze the characteristics and relationship of mediotrusive contacts with occlusion and the temporomandibular joint, in patients who consult the Occlusion and TMJ Service of the Dental Hospital of the Faculty of Dentistry of the National University of the Northeast (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.


Background: Temporo-mandibular joint dislocation is a displacement of the condyle, out of its functional positions within the articular fossa and articular eminence, causing a complete loss of joint function. Chronic dislocation is any acute dislocation that progresses without specific treatment and that can be recurrent. Eminectomy is a definitive surgical treatment for chronic temporomandibular joint dislocation. Objective: To report the clinical case of a male patient in the third decade of his life with a diagnosis of chronic dislocation of the temporomandibular joint of 5 months of evolution and to carry out an updated review of the literature on this surgical procedure. Case Report: The patient was treated surgically with bilateral eminectomy. Discussion: Eminectomy is a controversial surgical procedure; recent research classifies it as safe and effective. Conclusion: The presented clinical case shows a good result.

ABSTRACT

ABSTRACT Introduction: Temporomandibular disorder (TMD) refers to a group of conditions that compromise the harmonious movement and function of the temporomandibular joint, masticatory muscles, and associated structures. The etiopathogenesis of TMD is multifactorial but not well-understood, with the role of genetic factors still being unclear. Objective: This review aims to summarize the results of studies that evaluated TNF-α levels and the -308G/A TNF-α polymorphism in TMD patients. This study emphasizes the importance of a more selective treatment involving TNF-α inhibitors that can potentially reduce inflammation and pain, and improve quality of life. Methods: The MEDLINE/PubMed database, Cochrane Library, and Web of Science database were searched for case-control studies published until September 2020 that compared levels of TNF-α or presence of its -308G/A polymorphism in TMD patients and healthy individuals. Results: Six case-control studies were identified with a total of 398 TMD patients, aged between 12 and 78 years. The control group consisted of 149 subjects, aged between 18 and 47 years. The occurrence of TMD was predominant in females. Majority of studies found high TNF-α levels in TMD patients, compared to the control group. One of these studies found a positive correlation between the GA genotype and the development of TMD. Conclusion: Majority of the TMD patients showed elevated TNF-α levels, and a possible explanation for this could be the presence of the -308G/A polymorphism.


RESUMO Introdução: A disfunção temporomandibular (DTM) é definida como um grupo de alterações que comprometem a articulação temporomandibular, os músculos mastigatórios e as estruturas associadas. A etiopatogenia da DTM é multifatorial, e o papel dos fatores genéticos permanece obscuro. Objetivo: A presente revisão teve como objetivo descrever as contribuições de estudos que avaliaram os níveis de TNF-α e o polimorfismo -308 G/A em pacientes com DTM. Esse estudo enfatizou a importância de um tratamento mais completo envolvendo os inibidores do TNF-α que podem potencialmente reduzir a inflamação e a dor, contribuindo para melhorar a qualidade de vida do paciente. Métodos: As pesquisas foram realizadas nas bases de dados MEDLINE/PubMed, Cochrane Library e Web of Science, em busca de estudos de caso-controle publicados até setembro de 2020 que avaliassem os níveis de TNF-α e seu polimorfismo -308 G/A nos pacientes com DTM e em controles saudáveis. Resultados: Seis estudos de caso-controle foram identificados, com um total de 398 pacientes com DTM, e a idade variou de 12 a 78 anos. O grupo controle consistiu de 149 indivíduos e sua idade variou, aproximadamente, de 18 a 47 anos. O sexo feminino foi predominante. A maioria das pesquisas encontrou níveis elevados de TNF-α nos pacientes, em comparação com os controles. Um estudo encontrou uma associação positiva entre o genótipo GA e o desenvolvimento de DTM. Conclusão: A maioria dos pacientes com DTM demonstrou predisposição a uma maior produção de TNF-α, e isso poderia ser explicado pela presença do polimorfismo -308 G/A.

ABSTRACT

Resumo Como abordar uma doença que traz vivências tão singulares e fazê-lo sem dissociações com as relações, as condições de vida e sociedade? A Disfunção temporomandibular (DTM) é um grupo de desordens crônicas difíceis de diagnosticar e prover tratamento. Como em outras doenças similares, tais dificuldades podem agravar o impacto negativo sobre a saúde. O estudo busca identificar vivências de usuários de serviços de saúde com DTM, visando contribuir com as práticas de reflexão e manejo para a questão. Foi desenvolvido um estudo qualitativo, de caráter otobiográfico, a partir de entrevistas com pessoas em tratamento de DTM. Parte-se da premissa nietzschiana de que o processo de subjetivação é alimentado por vivências; portanto, o método busca a identificação de traços dessas vivências nos textos produzidos a partir da transcrição das entrevistas. As vivências dos pacientes foram agrupadas em cinco trincheiras: nomeação; frustrações; escondido; tristeza, medo e morte; e destinos. Uma variedade de efeitos negativos foi descrita através dos três primeiros estágios, enquanto em destinos, emergem as sensações de bem-estar. Destaca-se o valor do espaço profissional-usuário, que expressa a potência de criação de modos inovadores e sensíveis de lidar com os processos de saúde-doença.


Abstract How does one address an ailment related to such unique experiences without dissociating it from relationships, living conditions and society? Temporomandibular Disorder (TMD) is one of a group of chronic disorders that are difficult to diagnose and provide treatment. As in other similar ailments, such difficulties may accentuate a negative impact on health. The study seeks to identify experiences of health service users with TMD, aiming to contribute to reflection and management practices for the issue. A qualitative otobiographical study was developed, using interviews with people undergoing TMD treatment. Based on the Nietzschean premise that the process of subjectivation is fed by experiences, the method seeks to identify traces of these experiences through the texts resulting from the interviews. Patients' experiences were grouped into five categories: recognition; frustrations; concealment; sadness, fear and death; and destinies. A variety of negative effects have been described in the first three stages, whereas the last one, namely destinies, elicits feelings of well-being. The value of the interactive (professional-user) space, which expresses itself as the power to create innovative and sensitive ways of dealing with health-disease processes, needs to be highlighted.

ABSTRACT

Introducción: Los desórdenes temporomandibulares son un grupo de trastornos que afectan la articulación temporomandibular y/o los tejidos musculoesqueléticos asociados. Objetivo: Determinar la efectividad de los concentrados de plaquetas en el tratamiento de los desórdenes temporomandibulares. Métodos: La búsqueda de la literatura fue realizada desde enero del 2014 hasta abril del 2019, en las bases de datos biomédicas: PubMed, Embase, SciELO, Scopus, Science Direct, Sistema de información sobre literatura gris en Europa, Literatura Latinoamericana y del Caribe en Ciencias de la Salud, Google Académico y el Registro Central de Ensayos Clínicos Cochrane. Se definieron como criterios de selección de los estudios que fueran ensayos clínicos aleatorizados, con una antigüedad máxima de cinco años, que reportarann la efectividad (reducción del dolor y aumento de apertura máxima) de los concentrados plaquetarios en el tratamiento de los desórdenes temporomandibulares. El riesgo de sesgo de los estudios fue analizado por medio del Manual Cochrane de revisiones sistemáticas de intervenciones. Resultados: La estrategia de búsqueda resultó en nueve artículos, de los cuales el 100 por ciento reportó que no había diferencia en la reducción del dolor y el aumento de apertura máxima de los concentrados plaquetarios en el tratamiento de los desórdenes temporomandibulares. Conclusiones: La literatura revisada sugiere que existe una ligera evidencia de los beneficios potenciales de las inyecciones intraarticulares de los concentrados plaquetarios en pacientes con desórdenes temporomandibulares. Sin embargo, es necesario establecer un protocolo estandarizado para la preparación y aplicación de estos concentrados(AU)


Introduction: Temporomandibular disorders are a group of dysfunctions which affect the temporomandibular joint and/or associated musculoskeletal tissues. Objective: Determine the effectiveness of platelet concentrates in the treatment of temporomandibular disorders. Methods: A bibliographic search was conducted from January 2014 to April 2019 in the biomedical databases PubMed, Embase, SciELO, Scopus, Science Direct, System for Information on Gray Literature in Europe, Latin American and Caribbean Health Sciences Literature, Google Scholar, and Cochrane Central Register of Clinical Trials. The following selection criteria were defined for the studies: randomized clinical trials published in the last five years and reporting on the effectiveness (pain reduction and maximum opening increase) of platelet concentrates in the treatment of temporomandibular disorders. Bias risk analysis was based on the Cochrane manual of systematic reviews of interventions. Results: Nine papers were retrieved, of which 100 percent reported no differences in pain reduction or maximum opening increase resulting from the use of platelet concentrates in the treatment of temporomandibular disorders. Conclusions: The literature review conducted suggests that there is slight evidence of the potential benefits of intra-articular injections of platelet concentrates in patients with temporomandibular disorders. However, a standardized protocol should be established for the preparation and application of these concentrates(AU)

ABSTRACT

Objetivo. Estimar la prevalencia de trastornos temporomandibulares (TTM) en estudiantes de Odontología de la Universidad Juárez del Estado de Durango, México. Material y métodos. Se trata de un estudio descriptivo, observacional, prospectivo y transversal. El universo de estudio contempló a la población estudiantil de la Facultad de Odontología, de la Universidad Juárez del Estado de Durango (México). Se incluyeron alumnos que cursaron del 1.o al 8.o semestre durante el ciclo escolar 2018-A, con edades entre los 18 y 28 años, a quienes se les aplicó un instrumento (índice anamnésico simplificado de Fonseca) que permitió caracterizar los TTM. El tamaño de la muestra se determinó utilizando el software Epi InfoTM y se obtuvo un tamaño de muestra total de 263 individuos. Para describir los datos, se utilizó el paquete estadístico R Studio Team (2019). Resultados. La prevalencia total de TTM en la población estudiada fue del 63% y el TTM más prevalente fue el leve, con un 44%. La prueba Ji2 entre el sexo y el TTM muestra significancia estadística (p = 0,001), igual que entre el sexo y los ítems del índice simplificado de Fonseca: ítem 4 (p = 0,001), ítem 7 (p = 0,021), ítem 8 (p = 0,021), ítem 9 (0,001) y el ítem 10 (p = 0,001). Conclusiones. Existe una alta prevalencia de TTM en la población estudiantil de la Facultad de Odontología de la Universidad Juárez del Estado de Durango (México), y el sexo femenino tiene una relación con la presencia y la manifestación de síntomas en estos trastornos. (AU)


Objective: The objective was to estimate the prevalence of temporomandibular disorders (TMD), in students of the Faculty of Dentistry. Material and Methods: This was a descriptive, observational, prospective, cross-sectional study. The study included 18 to 28-year-old students from the Faculty of Dentistry of the Universidad Juárez del Estado de Durango, México, attending the 1st to 8th semester of the 2018-A school year in whom the simplified Fonseca anamnestic index (sFAI) was applied to characterize TMD. The sample size was determined using the Epi InfoTM software, obtaining a total sample size of 263 individuals. The R Studio (2019) statistical package was used to describe the data. Results: The prevalence of TMD in the study population was 63%, with a mild disorder being the most prevalent in 44%. The Chi2 test showed statistically significant differences between sex and TMD (p = 0.001) and between sex and 5 items of the sFAI: item 4 (p= 0.001), item 7 (p= 0.001), item 8 (p = 0.021), item 9 (p= 0.001) and item 10 (p = 0.001). Conclusions: There is a high prevalence of TMD in the student population of the Faculty of Dentistry of the Universidad Juárez del Estado de Durango, Mexico, with females presenting a higher prevalence of the presence and manifestation of symptoms in these disorders.

ABSTRACT

Este estudo objetivou verificar as principais manifestações bucofaciais que as doenças reumáticas podem causar. Foram selecionadas, assim, 05 doenças reumáticas: Artrite Reumatóide (AR), Síndrome de Sjogren (SS), Lúpus Eritematoso Sistêmico (LES), Esclerose Sistêmica (ES) e a Síndrome de Behçet (SB). Estas, por sua vez, foram escolhidas por apresentarem como sinais e sintomas clínicos problemas orofaciais. Foi elaborado, dessa maneira, uma revisão bibliográfica de trabalhos com vintênio de 2000 a 2020 nas seguintes bases: LILACS, MEDLINE e SCIELO. Propõe-se, portanto, a introdução de um Cirurgião-dentista na equipe multidisciplinar de Reumatologia para diagnosticar e tratar as especificidades bucofaciais que acometem os portadores de problemas reumáticos...

This study aimed to verify as main bucofacial manifestations that rheumatic diseases can cause. Thus, 05 rheumatic diseases were selected: Rheumatoid Arthritis (RA), Sjogren's Syndrome (SS), Systemic Lupus Erythematosus (SLE), Systemic Sclerosis (ES) and Behçet's Syndrome (SB). These, in turn, were chosenbecause they present as orofacial clinical signs and symptoms. In this way, a bibliographic review of works with twenty years from 2000 to 2020 was prepared on the following bases: LILACS, MEDLINE and SCIELO. Therefore, it is proposed to introduce a dental surgeon in the multidisciplinary team of Rheumatology to diagnose and treat as orofacial specificities that affect patients with rheumatic problems...

ABSTRACT

Disfunção Temporomandibular (DTM) apresenta-se como principal causa de dores orofaciais de origem não dentária. A acupuntura é indicada para o alívio de da dor em casos de DTM muscular, baseada em propriedades anti-inflamatórias com efeitos neuro-hormonais. Objetivou-se nesta pesquisa a avaliação da eficácia da acupuntura como um método válido para redução imediata da sintomatologia dolorosa e limitação de abertura bucal nos casos de DTM. Realizou-se terapia acupuntural em 30 pacientes com DTM, avaliando-se a dor, a partir da Escala Verbal (EV) e da Escala Analógica Visual (EAV) e a limitação de abertura bucal com o auxílio de paquímetro digital antes e após a terapia para registro da análise. O aumento da média de abertura bucal foi de 9,2% no total de participantes. Quanto à sintomatologia dolorosa, apresentou redução média em 63%. Na EV, 27 dos pacientes tiveram resposta "moderada" e "intensa" para sensação dolorosa. Contudo, após a terapia, observou-se ausência de sensação dolorosa intensa. Os dados apontaram significância da terapia acupuntural para redução dor e limitação de abertura bucal, de forma imediata, em pacientes com DTM... (AU)


Temporomandibular Disorder (TMD) is the main cause of orofacial pain of non-dental origin. Acupuncture is indicated for pain relief in cases of muscle TMD, based on anti-inflammatory properties with neuro hormonal effects. The aim of this research was to evaluate the effectiveness of the acupuncture as a valid method for immediate reduction of painful symptoms and mouth opening limitation in TMD cases. Acupuncture therapy was performed in 30 patients with TMD, evaluating pain from the Verbal Scale (VE) and Visual Analog Scale (VAS) and mouth opening limitation with the aid of a digital caliper before and after therapy to record the analysis. The increase in the average mouth opening was 9.2% in the total number of participants. As for painful symptoms, an average reduction of 63%. In IV, 27 of the patients had "moderate" and "intense" responses to painful sensation. However, after therapy, the absence of intense painful sensation was observed. The data showed the significance of acupuncture therapy for immediate pain reduction and mouth opening limitation in patients with TMD... (AU)

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)

Se utilizaron métodos del nivel teórico, empírico, estadísticos y matemáticos. Resultados: El 52,5 % de los pacientes presentó trastornos temporomandibulares, de los cuales, la relación de molares era bilateral en el 80 %. Con respecto a la relación de caninos, todos los afectados presentaron relación de mesio, disto o combinación de ellas. La mayoría de los no afectados (89,5 %) tenía coincidencia de las líneas media. Conclusiones: Se constata que cualquier alteración en la oclusión dentaria según los criterios de Andrews tendrán consecuencias en el sistema estomatognático y, por tanto, en la aparición de los trastornos temporomandibulares.


ABSTRACT Introduction: The study of occlusion and its role in the etiology of temporomandibular disorders has been a controversial topic of interest in the stomatological field. Objective: To determine the relationship between occlusion, according to key I of the Andrews criteria, and temporomandibular disorders. Method: An observational, descriptive, cross-sectional study was carried out on students of dentistry at the Clínica Estomatológica Docente Provincial of the city of Sancti-Spíritus, in the period from September 2018 to September 2019. The population was of 42 students, the simple random sample consisted of 40 of them, those who responded to the inclusion criteria. The study variables were: presence of temporomandibular disorder, canines and molars ratio and coincidence of dental midlines. Methods of the theoretical, empirical, statistical and mathematical levels were used. Results: 52.5% of the patients presented temporomandibular disorders, of which the molar relationship was bilateral in 80%. Regarding the relationship of canines, all those affected presented a relationship of mesio, disto or a combination of them. Most of the unaffected (89.5%) had midline coincidence. Conclusions: It is found that any alteration in dental occlusion according to the Andrews criteria will have consequences on the stomatognathic system and, therefore, on the appearance of temporomandibular disorders.

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.

ABSTRACT

Pain of the orofacial region is the primary complaint for which patients seek treatment. Of all the orofacial pain conditions, one condition that possess a significant global health problem is temporomandibular disorder (TMD). Patients with TMD typically frequently complaints of pain as a symptom. TMD can occur due to complex interplay between peripheral and central sensitization, endogenous modulatory pathways, and cortical processing. For diagnosis of TMD pain a descriptive history, clinical assessment, and imaging is needed. However, due to the complex nature of pain an additional step is needed to render a definitive TMD diagnosis. In this review we explicate the role of different biomarkers involved in painful TMD. In painful TMD conditions, the role of biomarkers is still elusive. We believe that the identification of biomarkers associated with painful TMD may stimulate researchers and clinician to understand the mechanism underlying the pathogenesis of TMD and help them in developing newer methods for the diagnosis and management of TMD. Therefore, to understand the potential relationship of biomarkers, and painful TMD we categorize the biomarkers as molecular biomarkers, neuroimaging biomarkers and sensory biomarkers. In addition, we will briefly discuss pain genetics and the role of potential microRNA (miRNA) involved in TMD pain.

ABSTRACT

OBJECTIVES@#This study was conducted to investigate the brain function of patients with temporomandibular disorders (TMD) by combining the static and dynamic amplitudes of low-frequency fluctuation (ALFF).@*METHODS@#Thirty patients with TMD and 20 healthy controls were enrolled. All the participants completed their questionnaires, received clinical examinations, and underwent resting-state functional magnetic resonance imaging scanning. We compared the static and dynamic ALFF between the patients and healthy controls by conducting a two-sample @*RESULTS@#The patients with TMD showed increased static and dynamic ALFF in the posterior cingulate cortex compared with that of the controls (whole-brain level, uncorrected @*CONCLUSIONS@#Our findings revealed that the resting-state brain function of the posterior cingulate cortex and the medial orbitofrontal cortex of patient with TMD increased. These changes probably indicated the potential central mechanisms underlying the increased self-relevant thoughts, negative emotion, and abnormal emotion regulation in TMD.

ABSTRACT

Objetivo: evaluar la rehabilitación funcional de la ATM en pacientes con osteoartrosis, con abordaje neuromuscular. La osteoartrosis se caracteriza por la degeneración del cartílago articular y la cortical ósea, que conduce a dolor e inmovilidad. Se incluyó a 8 mujeres entre 20 y 42 años de edad con dolor en la región orofacial, signos de oclusión disfuncional e imágenes compatibles con trastornos degenerativos en ATM. Clínicamente se evaluó el dolor y la oclusión y, mediante tecnología electrónica, se obtuvieron datos objetivos de los movimientos de apertura-cierre y lateralidades, la velocidad de apertura-cierre mandibulares y de los ruidos articulares. Las mediciones fueron realizadas al inicio y al finalizar el tratamiento de estabilización mandibular con una ortosis neuromuscular. Para determinar la significación estadística se utilizaron el Student`s test de comparaciones múltiples y el análisis de varianza, ANOVA, de un factor. Las diferencias entre medias se consideraron significativas con p <0.05. Los resultados demostraron ausencia de dolor en el 100% de los casos al primer mes de tratamiento. Se incrementaron la apertura bucal (6,73 mm promedio), ambas lateralidades (P=0.0023), velocidad en apertura y en cierre (no estadísticamente significativo). Después de estabilizar la mandíbula se redujo la frecuencia de los ruidos. En conclusión, la oclusión dental disfuncional es el principal factor etiológico de la artrosis de la ATM. El establecimiento de una oclusión fisiológica produce la descompresión de la ATM, aumenta el rango de los movimientos mandibulares y disminuye significativamente el dolor (AU)


Objective: to evaluate the functional rehabilitation of the TMJ in patients with osteoarthritis, with a neuromuscular approach. Osteoarthrosis is characterized by degeneration of articular cartilage and bone cortex, which leads to pain and immobility. Eight women between 20 and 42 years of age with pain in the orofacial region, signs of dysfunctional occlusion, and images consistent with degenerative TMJ disorders were included. Clinically, pain and occlusion were evaluated and, using electronic technology, objective data were obtained on the opening-closing movements and lateralities, the opening-closing speed of the jaws and joint noises. Measurements were made before and at the end of the mandibular stabilization treatment with a neuromuscular orthosis. To determine the statistical significance, the Student`s multiple comparisons test and the analysis of variance, ANOVA, of one factor were used. The differences between means were considered significant with p <0.05. The results showed absence of pain pain in 100% of cases in the first month of treatment. Mouth opening (6.73 mm average), both lateralities (P = 0.0023), opening and closing speed (not statistically significant) were increased. After stabilizing the jaw the noise frequency value was reduced. In conclusion, dysfunctional dental occlusion is the main etiologic factor of TMJ osteoarthritis. Establishing a physiological occlusion causes TMJ decompression, increases the range of mandibular movements, and significantly decreases pain (AU)

ABSTRACT

Abstract The objective of this study was to evaluate if individuals with dentofacial deformities (DFD) who require orthognathic surgery are affected more by depression and pain. A case-control study was performed with 195 individuals. In the DFD group, 145 individuals with Class II and III malocclusion requiring orthognathic surgery were selected. The control group was composed of 50 individuals with no DFD. All patients were diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Data were analyzed with a significance level of 0.05. The DFD group more often presented severe depression (p = 0.020) and chronic pain (p = 0.017). They also presented higher prevalence of Nonspecific Physical Symptoms Including Pain (P = 0.002) and Nonspecific Physical Symptoms Excluding Pain (p = 0.002). Concerning TMD symptoms, the DFD group had more myofascial (p = 0.002) and articular pain (p = 0.041). Therefore, the results of this study suggest that depression and pain are more common in individuals with DFD requiring orthognathic surgery compared with individuals without DFD.
