ABSTRACT

Resumen Introducción: El bruxismo está definido como una actividad oral motora que consiste en el apretamiento o rechinamiento involuntario (rítmico o espasmódico no funcional) de los dientes, con una prevalencia de 5,9% a 49,6% en niños. Lo que podría contribuir a problemas clínicos asociados con la articulación temporomandibular. La asociación entre la disfunción temporomandibular (DTM) y el bruxismo en niños aún no está totalmente establecida. Objetivo: El objetivo de esta revisión de literatura es recopilar información actualizada de estudios que hayan abordado la asociación entre el bruxismo y la disfunción temporomandibular en niños de 3 a 12 años. Metodología: Se realizó una búsqueda en las bases de datos de Scopus, Pubmed y Scielo usando los descriptores "Niño", "Niños", "Preescolar", "Bruxismo", "Bruxismo del sueño", "Disfunción Temporomandibular"; y, "Síndrome de la Disfunción de Articulación Temporomandibular". Fueron incluidos artículos publicados en los últimos 15 años en idiomas español, inglés y portugués. Fueron incluidos estudios transversales, de cohorte, casos controles y ensayos clínicos aleatorizados. Resultados: Se evaluaron 242 artículos, de los cuales solo 11 fueron incluidos de acuerdo a los criterios de inclusión. Entre los estudios incluidos, dos de ellos no encontraron asociación entre DTM y bruxismo, tres encontraron una tendencia o probable asociación y seis encontraron una asociación positiva. Conclusiones: Existen estudios que relatan asociación entre el bruxismo y las disfunciones temporomandibulares en niños de 3 a 12 años, relacionando la presencia de signos y síntomas de la DTM con el bruxismo, pudiendo ser este último, un factor de riesgo para la presencia de DTM.


ABSTRACT Introduction: Bruxism is defined as an oral motor activity that consists of involuntary clenching or grinding (non-functional rhythmic or spasmodic) of the teeth, with a prevalence rate ranging from 5.9% to 49.6% in children, which could contribute to clinical problems associated with the temporomandibular joint. The association between bruxism in children and temporomandibular dysfunction (TMD) is not yet fully established. Objective: The objective of this literature review is to collect up-to-date information on studies that have addressed the association between bruxism and temporomandibular dysfunction in children ranging 3 - 12 years of age. Methods: A search was performed in the Scopus, PubMed and SciELO databases using the descriptors "Child", "Children", "Child, Preschool", "Bruxism", "Sleep Bruxism", "Temporomandibular Dysfunction" and "Temporomandibular Joint Dysfunction Syndrome." Articles published in the last 15 years in the Spanish, English and Portuguese languages were included. Results: A total of seventy-two articles were assessed. Only 11 articles were included according to the inclusion criteria. Among the included studies, two of them found no association between TMD and bruxism, three found a trend or probable association, and six found a positive association. Conclusion: There are studies that report an association between bruxism and temporomandibular dysfunctions in children ranging 3 - 12 years old, relating the presence of signs and symptoms of TMD with bruxism.

ABSTRACT

Introdução: A disfunção temporomandibular é um problema de saúde pública bastante subnotificado. Além disso, o seu diagnóstico é complexo e exige o uso de instrumentos válidos e confiáveis para uso em estudos epidemiológicos. Objetivo: Validar o instrumento de diagnóstico epidemiológico da DTM (IDE/DTM), com aplicabilidade para estudos epidemiológicos nacionais. Metodologia: Trata-se de um estudo de validação, foram avaliadas a validade da estrutura interna através da Análise Fatorial Exploratória (AFE), confiabilidade (consistência interna, interobservadores e intraobservador) e a validade convergente do IDE/DTM usando os Critérios de Diagnóstico para Disfunção Temporomandibular (DC/TMD) como padrão-ouro. A amostra foi composta por 221 voluntários, 120 na etapa de AFE, 50 para o teste-reteste e 101 na validade convergente. Resultados: A AFE revelou 3 dimensões (DTM Muscular, DTM Articular e Diagnóstico diferencial) com todos os itens com cargas fatoriais > 0.4, que explicaram 73,3% da variância total. Boa consistência interna com alfa de Cronbach= 0,775. A confiabilidade variou entre substancial e excelente, reprodutibilidade interobservadores (Kappa=0,74-1,00, ICC=0,91-0,97; p< 0,001) e intraobservador (Kappa= 0,75-0,94, ICC=0,80-0,98; p< 0,001). O escore total do IDE/DTM apresentou critérios de diagnósticos válidos e satisfatórios segundo o DC/TMD (Kappa= 0,906; p<0,001), com capacidade para diferenciar indivíduos sem e com DTM com ponto de corte de 4,9 (Sensibilidade=1,0; Especificidade= 1,0; AUR=1,0), DTM Mista com ponto de corte de 14 ou mais (Sensibilidade=0,8; Especificidade=1,0; AUR=0,987), e DTM Muscular (Sensibilidade=1,0; Especificidade= 0,88; VPP= 0,89; VPN= 1,0) ou DTM Articular (Sensibilidade=0,95; Especificidade= 0,87; VPP= 0,83; VPN=0,96) com ponto de corte entre 5-13,9 pontos, sendo o diagnóstico obtido a partir da maior pontuação em cada dimensão (Muscular ou Articular). Conclusão: O IDE/DTM é um instrumento de avaliação válido e confiável, com propriedades psicométricas adequadas e satisfatórias, capaz de diagnosticar pessoas com DTM e classificar o subtipo da condição (Muscular, Articular e Mista) (AU).


Introduction: Temporomandibular disorders (TMD) is a highly underreported health problem. In addition, its diagnosis is complex and requires the use of valid and reliable instruments for use in epidemiological studies. Objective: To validate the Epidemiological Diagnostic Instrument for TMD (EDI/TMD), with applicability for national epidemiological studies. Methodology: This is a validation study, internal structure validity through Exploratory Factor Analysis (EFA), reliability (internal consistency, interobserver and intraobserver), and convergent validity of the EDI/TMD were assessed using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) as the gold standards. The sample was composed of 221 volunteers, 120 in the EFA stage, 50 for the test-retest, and 101 for convergent validity. Results: AFE showed three factors (Muscles TMD, Joint TMD, and Differential Diagnosis) with all items having factor loadings > 0.4, which explained 73.3% of the total variance. Good internal consistency with Cronbach's alpha= 0.775. Reliability ranged from substantial to excellent, reproducibility interobserver (Kappa=0.74-1.00, ICC=0.91-0.97; p< 0.001) and intraobserver (Kappa= 0.75-1.00, ICC=0.80-0.98; p< 0.001). The EDI/TMD total score showed valid and satisfactory diagnostic criteria according to the DC/TMD (Kappa= 0.906; p<0.001), with the ability to differentiate between individuals without and with TMD with a cut-off point of 4.9 (Sensitivity=1.0; Specificity=1.0; AUR=1.0); Mixed TMD with a cut-off point of 14 or more (Sensitivity=0.8; Specificity=1.0; AUR=0.987); and either Muscles TMD (Sensitivity=1.0; Specificity= 0.88; PPV= 0.89; NPV=1.0) or Joint TMD (Sensitivity=0.95; Specificity= 0.87; PPV= 0.83; NPV=0.96), with a cut-off point between 5-13.9, with the diagnosis obtained from the highest score in each factor (Muscles or Joint). Conclusion: The EDI/TMD is a valid and reliable assessment tool, with adequate and satisfactory psychometric properties, capable of diagnosing people with TMD and classifying the subtype of the condition (Muscles, Joint, and Mixed) (AU).

ABSTRACT

ABSTRACT Objective: To evaluate the prevalence of temporomandibular disorders (TMD) in students and to evaluate if any relationship existed between the stress levels, salivary cortisol levels, and TMD. Material and Methods: A total of 348 students, 187 female, and 161 male students, participated in this cross-sectional study. Students were evaluated based on the Research Diagnostic Criteria for TMD. The stress levels were evaluated using the Perceived Stress Scale. The students were divided into the control and TMD groups. Salivary cortisol levels in the salivary samples were analyzed. Results: The prevalence rate of TMDs was 30.7% in the study population. Of the female students, 61% had TMD compared with 46% of male students. Muscle disorders were the most predominant disorder in 14.2% of the students with TMD. The TMD group showed significantly higher salivary cortisol and stress levels than the control group. The TMD group also showed a moderate positive correlation between cortisol and stress levels (p=0.01). Conclusion: The study showed a strong association between salivary cortisol levels, stress, and temporomandibular disorders. Salivary cortisol could be used as a prognostic biomarker for stress while assessing the severity of TMJ problems in stressed individuals.

ABSTRACT

La presencia de desórdenes temporomandibulares (TTM) en el niño es un tema controversial. Algunos autores sostienen su ausencia en la población infantil; sin embargo, otros han observado signos y síntomas de TTM en poblaciones pediátricas. Nosotros creemos que tales desórdenes pasan inadvertidos con frecuencia por la falta de un examen clínico completo y minucioso que incluya el estudio de la ATM como parte del sistema estomatognático y como revisión rutinaria en la clínica odontopediátrica. Ante las reiteradas consultas que recibimos en la asignatura Odontología Niños de la FOLP, surgió la inquietud de profundizar en el tema y decidimos realizar un trabajo de investigación denominado : "Disfunciones temporomandibulares y su relación con trastornos de ansiedad en una población infantil". El objetivo general de este trabajo fue determinar los signos y síntomas de los TTM y su relación con los distintos niveles de trastornos emocionales en una población infantil, con el propósito de brindar información a odontólogos y odontopediatras acerca de la importancia de realizar un correcto examen clínico de la ATM que nos alerte sobre la posibilidad de aparición de TTM en niños, sin dejar de estar atentos a los miedos o los diferentes grados de ansiedad que los niños pueden desarrollar y que contribuyen en buen grado a agravar o desencadenar el cuadro.

ABSTRACT

A disfunção temporomandibular tem caráter multifatorial e merece uma abordagem diferenciada tanto para seu diagnóstico quanto seu tratamento, sendo frequentemente recomendada a atuação de uma equipe multidisciplinar. Várias são as manifestações que podem acometer as articulações temporomandibulares decorrentes de patologias sistêmicas. Dentre estas, a tuberculose raramente as acomete, mas a ocorrência de manifestações extrapulmonares vem crescendo nos últimos anos. Estima-se que a tuberculose acometa 8.8 milhões de pessoas ao ano, levando 1.45 milhões destas ao óbito. O objetivo desta revisão foi levantar dados e informações para profissionais da área da saúde, em especial os Cirurgiões Dentistas,para um correto e precoce diagnóstico, uma vez que a detecção correta da patologia possibilita tratamento adequado e previne o surgimento de alterações graves na forma e função das articulaçõesenvolvidas.


Temporomandibular disorders are a multifactorial disease, that deserves a special approachfor its diagnosis and treatment, and a multidisciplinary team is suggested. Various systemic pathologies have a TMJ manifestation. Among these diseases, tuberculosis rarely has a temporomandibularjoint occurrence, but extra pulmonary manifestation is increasing in the last years.About 8,8 million people are affected by tuberculosis each year, and 1,45 million die because ofit. The objective of this review is collect data and information for health professional, in special Dentists, in order to clarify the relationship between TMD and tuberculosis, early diagnosis and correct treatment, once that the correct identification of this patology can provide adequate treatment and prevents for more severe complications.

ABSTRACT

A disfunção temporomandibular (DTM) é uma condição comum, que afeta até 28% da população. A articulação temporomandibular (ATM) é uma articulação complexa, composta por uma série de estruturas teciduais ósseas e moles, e cada uma das quais podem estar implicada em funções fisiológicas específicas e em síndromes associadas a patologias clínicas. O conhecimento da aparência da imagem normal da ATM, a sua aparição no exame radiológico e técnicas intervencionistas são úteis para fornecer uma contribuição diagnóstica eficiente. Anormalidades da ATM não podem ser avaliadas de forma confiável apenas por exame clínico, mas com o uso da RM podemos descrever alterações articulares que não eram vistas em qualquer outro método de imagem, indicando ser este o melhor método diagnóstico. Este artigo teve o objetivo de evidenciar a importância do uso da RM para diagnóstico das alterações da ATM, exemplificando diversas condições descritas com seu auxílio...


Emporomandibular disorders (TMD) is a common condition that affects up to 28% of the population. Temporomandibular joint (TMJ) is a complex articulation which consists of bones and soft tissue structures, each of which may be implicated in specific physiological functions and in clinical syndromes associated pathologies. Knowledge of the appearance of the normal image of TMJ, its appearance in the radiological examination, and interventional techniques are useful to provide efficient diagnostic contribution. TMJ abnormalities can not be evaluated only reliably by clinical examination, but with the use of MRI we can describe articular changes that were not seen in any other imaging method, indicating that this is the best diagnostic method for this task. This article aims to highlight the importance of MRI for diagnosis of impaired TMJ exemplifying various conditions described in the rescue...

ABSTRACT

Los Criterios Diagnósticos para la Investigación de los Trastornos Temporomandibulares (CDI/TTM) ofrecen un sistema estandarizado para evaluar la Disfunción Temporomandibular (DTM). Sin embargo, la validez del diagnóstico clínico obtenido con estos criterios al compararlo con el diagnóstico obtenido de las imágenes de Resonancia Magnética (RM) es controversial. El objetivo fue determinar la concordancia que existe entre la evaluación clínica realizada con los CDI/TTM e imágenes de RM de la articulación temporomandibular (ATM), de pacientes atendidos en la Clínica Integral del Adulto, de la Escuela de Odontología de la Universidad del Valle, en Cali, Colombia. Se evaluó clínicamente a 36 individuos, con edades comprendidas entre 18 y 60 años, utilizando los CDI/TTM y se les realizaron exámenes de RM. Las variables estudiadas fueron sexo, edad, signos y síntomas de la ATM, Posición Normal del Disco (PND), Desplazamiento Discal con Recaptura (DDCR) y Desplazamiento Discal Sin Recaptura (DDSR). Los datos obtenidos fueron sometidos a pruebas estadísticas para determinar el índice Kappa y características operativas de la prueba clínica. El Índice Kappa fue 0,53, con una concordancia entre las evaluaciones clínicas e imagenológicas moderada. De la población estudiada, 91,6% fue del sexo femenino, con 31 años como promedio de edad. El signo hallado con mayor frecuencia fue el ruido articular (77%) y el síntoma más frecuente fue el dolor facial (69%). La sensibilidad de los CDI/TTM para determinar la PND fue 0,52 y la especificidad 0,87; la sensibilidad para el DDCR fue 0,8780 y la especificidad 0,709; la sensibilidad para el DDSR fue 0,5714 y la especificidad 0,948. La DTM se presentó con mayor frecuencia en las mujeres, con edad promedio de 31 años. Los CDI/TTM pueden considerarse confiables, especialmente para el DDCR; sin embargo, tratamientos invasivos, permanentes o quirúrgicos, requerirían confirmación con un diagnóstico imagenológico para evitar falsos positivos.


The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) offer a standardized system to clinically evaluate the most common subtypes of Temporomandibular Disorders (TMD). However, the validity of the clinical diagnose obtained with these criteria when compared with the diagnose obtained from the images of Magnetic Resonance (MR) is controversial. The objective of this study was to determine the concordance existing between the clinical evaluation obtained from the RDC/TMD and that obtained from MR images of the temporomandibular joint (TMJ) of patients attending the Clínica Integral del Adulto ­ Clínica de ATM, of the Escuela de Odontología of the Universidad del Valle, Cali, Colombia. A population of 36 patients of both sexes, with ages between 18 and 60 years, were clinically evaluated with the RDC/TMD and MR. The variables considered were sex, age, signs and symptoms of the TMJ, Normal Disc Position (NDP), Disc Displacement with Reduction (DD-R) and Disc Displacement without Reduction (DD-NR). The data obtained were submitted to statistical tests to determine the Kappa Index and operative characteristics of the clinical evaluation. The Kappa Index obtained was 0.53, which shows that the concordance between the clinical and the imagenological evaluations is moderate. Of the total population studied, 91.6% were females, with 31 years as average age. The most frequent sign found was the joint sound (77%) and the most frequent symptom was facial pain (69%). The sensitivity of the RDC/TMD to determine NDP was 0.52 and the specificity 0.87; the sensitivity for the DD-R was 0.8780 and the specificity 0.709; the sensitivity for the DD-NR was 0.5714 and the specificity 0.948. The TMD were found most frequent in women, with average age of 31 years. The RDC/TMD can be considered reliable, especially for the DD-R; however, invasive, permanent or surgical treatments would require confirmation with imagenological diagnoses to avoid false positives.

ABSTRACT

Objetivo Avaliar a confiabilidade e responsividade do duty factor à dor provinda da desordem temporomandibular Métodos Participaram 20 voluntárias, com média de idade de 29 anos e 6 meses (±9,2), portadoras de desordem temporomandibular miogênica, segundo o critério diagnóstico para pesquisa em Desordem Temporomandibular (RDC/TMD). Foram coletados sinais eletromiográficos nas condições de repouso dos músculos mastigatórios, na presença de dor moderada a severa e na diminuição ou eliminação desta dor após aplicação de Estimulação Elétrica Nervosa Transcutânea durante 45 minutos. Os sinais eletromiográficos de repouso foram processados para obtenção dos valores do tempo de ativação muscular acima de 10% do valor da máxima força de apertamento dentário. A confiabilidade foi testada pelo coeficiente de correlação intraclasse em dados repetidos antes da analgesia. Também foi calculado o erro padrão de medida e mínima mudança detectável. A responsividade da variável foi analisada entre as coletas eletromiográficas realizadas antes e após a analgesia pelo tamanho de efeito e média de resposta padronizada. Resultados Duty factor apresentou valores de coeficiente de correlação intraclasse acima de 0,75 para todos os músculos. O erro padrão foi entre 4% e 8% e a mínima mudança detectável entre 5% e 12%. Na responsividade da variável para a dor, o tamanho de efeito obteve valores entre 0,2 e 0,5 e a média da resposta padronizada, valores acima de 0,8. Conclusão O duty factor apresentou confiabilidade excelente e responsividade à dor da desordem temporomandibular baixa para tamanho de efeito e excelente para média da resposta padronizada. .


Purpose To assess the reliability and responsiveness of the duty factor variable for assessing pain originating from temporomandibular disorders. Methods The sample comprised 20 female volunteers, mean age 29 years 6 months (± 9.2), with a diagnosis of myogenic temporomandibular dysfunction according to the Research Diagnostic Criteria for Temporomandibular Disorders. Electromyographic (EMG) signals were collected at three times: during mandibular rest; in the presence of moderate to severe pain; and when pain was reduced to mild or absent after 45 minutes of transcutaneous electrical nerve stimulation (TENS). Electromyographic signals during mandibular rest were processed to obtain values for muscle activation time greater than 10% of maximum bite force. Reliability was tested with intraclass correlation for repeated data before analgesia. Standard error of measurement (SEM) and minimum detectable change (MDC) were also computed to determine reliability. Responsiveness of duty factor was analyzed between EMG recordings, before and after analgesia, by calculating effect size (ES) and standardized response mean (SRM). Results Duty factor presented intraclass correlation coefficient above 0.75 for all muscles. Standard error of measurement ranged from 4% to 8% and minimum detectable change from 5% to 12%. Regarding the responsiveness of duty factor to pain, effect size values fell between 0.2 and 0.5 and SRM values were greater than 0.8. Conclusion Duty factor showed excellent reliability. However, responsiveness to TMD-related pain was low as expressed by effect size and excellent as expressed by standardized response mean. .

ABSTRACT

Objetivo Comparar, entre portadoras de disfunção temporomandibular (DTM) e controles, o tempo de ativação do músculo masseter e do músculo temporal anterior, em diferentes faixas de amplitude eletromiográfica de superfície, durante a mastigação. Métodos Foram avaliadas 22 voluntárias, com idades entre 18 e 48 anos, divididas em Grupo DTM (n=14) do tipo “Ia”, de acordo com o Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TDM) e Grupo Controle (n=8), assintomáticas. Foram registrados, por meio de eletromiografia de superfície, a amplitude e o tempo de ativação dos músculos masseter e temporal anterior, durante mastigação bilateral de Parafilm M® por dez segundos. Os sinais eletromiográficos foram categorizados em três faixas percentuais, 0-39%, 40-74% e 75-100%, relativas ao valor médio de amplitude de três contrações máximas de apertamento dentário. As porcentagens dos tempos totais de ativação (duty factor), em cada uma das faixas de amplitude, foram comparadas entre os grupos pelo teste t-Student, para dados não pareados. Resultados Não houve diferenças significativas do duty factor na comparação entre os grupos controle e DTM. Conclusão A variável eletromiográfica testada não se mostrou útil como ferramenta diagnóstica na prática clínica, o que será possível apenas quando em conjunto com a história clínica e exame físico do indivíduo. .


Purpose This study aimed to compare the time of masseter and anterior temporal muscle activations, in different ranges of surface electromyographic amplitude, between controls and individuals with temporomandibular disorders (TMDs) during mastication. Methods Twenty-two female patients, aged 18-48 years, were divided into the TMD group (n=14; TMD type Ia, according to the Research Diagnostic Criteria for Temporomandibular Disorders) and the control group (n=8; non-diagnosed and asymptomatic individuals). Time and surface electromyography (SEMG) amplitudes from the anterior temporal and masseter muscles were registered during bilateral chewing of Parafilm M® for 10 s. SEMG amplitudes were categorized as 0-39%, 40-74%, and 75-100% of the mean of three maximal clenchings. The percentages of total activation times (duty factor) in each range of SEMG amplitudes were compared between groups using an unpaired Student’s t-test. Results: There were no differences in duty factor comparisons between groups. Conclusion: The activation time of the masticatory muscles was not found to be shorter in the TMD patients than in the controls. Finally, the application of the electromyographic variable proposed in this study may not be considered useful to diagnose type Ia TMD in clinical practice. However, its application may be complementary to the history and physical examination of these patients. .

ABSTRACT

La articulación temporomandibular constituye una de las estructuras faciales más complejas y ha sido reconocida como una causa de dolor y disfunción desde principios del siglo pasado. Su complicado funcionamiento determina que las mínimas alteraciones produzcan en ellas una gran diversidad de problemas funcionales, a los que se les conoce como trastornos temporomandibulares, que pueden originarse muy temprano con relación a las etapas de crecimiento y desarrollo craneofacial. El objetivo de este trabajo fue determinar la prevalencia de disfunción de la articulación temporomandibular e identificar los factores de riesgo asociados a estos trastornos en el grupo estudiado. Esta investigación fue de tipo descriptiva y transversal, cuyo universo de trabajo estuvo conformado por 320 niños, con edades comprendidas entre 7 y 11 años, pertenecientes a la Escuela primaria urbana Sofiel Riverón. El diagnóstico de disfunción fue realizado mediante la aplicación del Test de Krogh Paulsen. Los resultados mostraron que 6 de cada 100 niños encuestados presentaba disfunción temporomandibular y los factores de riesgo identificados con mayor frecuencia fueron: interferencias oclusales (45 por ciento), hábitos parafuncionales (35 por ciento), bruxismo (15 por ciento), estrés (5 por ciento). Fue apreciado un incremento de estos factores conjuntamente con las edades, aunque no de manera uniforme. Se hace necesario enfatizar en el examen funcional de la articulación temporomandibular en niños, ante la manifestación precoz de desórdenes temporomandibulares y mediante actividades de promoción, prevención e intervención clínicas oportunas, actuar sobre estos factores de riesgo y contribuir a disminuir las cifras de afectados.


The temporomandibular joint is one of the most complex facial structures and has been recognized as a pain and dysfunction source since the beginning of the last century. Its complicated functioning determines that the minimal alterations produce a great diversity of functional problems, known as temporomandibular disorders that may be originated very early with relation to the cranio-facial growing and development stages. The aim of this work was determining the prevalence of the temporomandibular joint dysfunction and identifying the risk factors associated to these disorders in the studied group. This was a cross- sectional descriptive research; the working universe was formed by 320 children aged 7-11 years, assisting the urban primary school Sofiel Riverón. The dysfunction diagnosis was made applying the Krogh Paulsen test. The results showed that 6 of every 100 inquired children had temporomandibular dysfunctions and the risk factors more frequently identified were: oclusal interferences (45 percent), parafunctional habits (35 percent), bruxism (15 percent), and stress (5 percent). It was appreciated these factors increment with the age, although not in an even way. It is necessary to emphasize in the functional examination of the children temporomandibular joint in the presence of precocious temporomandibular disorders and, through opportune activities of promotion, prevention and clinical intervention, influence on these risk factors and contribute to diminishing the number of affected children.

ABSTRACT

O presente estudo foi clínico duplo-cego randomizado, placebo controlado. Avaliou o efeito analgésico do acuponto Estômago 7 (E7) em pacientes portadores de Disfunção Temporomandibular. A possível analgesia foi estudada bilateralmente nos músculos masséter e temporal anterior. A proposição se estendeu a fim de elucidar se existem diferenças nos resultados quando se utiliza um ponto em um lado da face, se o resultado repercute do outro lado da face e se a acupuntura atua no limiar de dor do indivíduo. O estudo foi aprovado pelo Comitê de Ética em Pesquisa. A amostra constou de 56 pacientes. Todos os pacientes receberam a acupuntura real e acupuntura placebo, em sessão única. O acuponto E7 foi puncionado sempre do lado direito da face dos indivíduos. Os parâmetros utilizados para a avaliação foram a Escala Visual Analógica (EVA) e o Limiar de dor à Pressão (LDP). Avaliados antes e após o tratamento. A diminuição média do parâmetro EVA do lado direito foi de 39,73. Para o lado esquerdo, a diminuição média foi de 41,81. O parâmetro LDP aumentou imediatamente. O ponto isolado de acupuntura E7 promoveu a diminuição da dor do músculo masséter dos indivíduos. Foi possível agulhar um lado do paciente e atuar no lado oposto. O limiar de dor a pressão (LDP) medida no músculo-temporal anterior foi aumentado bilateralmente.


This was a clinical, double blind, randomized, placebo controlled study. It had the purpose of assessing the analgesic effect of acupoint Stomach 7 (S7) in patients with Temporomandibular Disorders. The possible analgesia was studied bilaterally on the masseter and anterior temporalis muscles. The proposal intended to find if there are differences in the results when a point on one side of the face is used and whether there is a repercussion on the other side of the face. Moreover, if acupuncture acts on the pain threshold of individuals. The study was approved by the Ethics Committee of Researches of the School of Dentistry of the University of São Paulo under number 544519. Fifty-six patients took part in the study. All the patients received real acupuncture and placebo acupuncture in a single appointment. Acupoint St7 was stimulated always on the right side of the patients faces. The parameters used for the assessment were the Visual Analog Scale (VAS) and the Pressure Pain Threshold (PPT), assessed before and after treatment. The mean decrease of VAS parameter on the right side was 39.73; and on the left side, the mean decrease was 41.81. The parameter PPT increased immediately. The isolated point of acupuncture St7 organized decrease of pain in the masseter muscle of patients. It was possible to puncture one side of the patient and act on the opposite side. The Pressure Pain Threshold (PPT) measured on the anterior temporalis muscle increased bilaterally.

ABSTRACT

A associação entre sinais e sintomas de Disfunções Temporomandibulares (DTM) e achados em imagens de ressonância magnética (RM) tem sido controversa, dessa forma, este estudo avaliou a posição do disco, pelo método do relógio, e verificou a associação com a posição da cabeça da mandíbula, com a dor muscular à palpação, abertura passiva e ativa, presença de estalo e idade em pacientes portadores de DTM que foram submetidos ao exame de RM. O disco foi classificado em 0- posição normal (banda posterior em 11 e 12 horas); 1- início do deslocamento (posição entre 11 e 10 horas); 2- deslocamento médio (posição entre 10 e 9 horas); e 3- deslocamento avançado (posição entre 9 e 8 horas). A posição da cabeça da mandíbula foi classificada de acordo com o método de Pullinger em 1- posterior; 2- anterior; e 3- concêntrica. As classificações foram realizadas por três examinadores. A associação entre os dados clínicos e imaginológicos foi realizada utilizando o coeficiente de correlação intraclasse, coeficiente de correlação de Spearman, análise de variância, teste exato de Fisher ou teste de Kruskal-Wallis conforme a necessidade, com 5% de nível de significância. Sessenta casos foram incluídos no estudo, com predomínio de mulheres e média de 37 anos de idade. Houve concordância excelente entre os examinadores para posição do disco e da cabeça da mandíbula, porém não houve correlação entre essas duas variáveis. A presença de estalo, dor muscular à palpação e amplitude de abertura de boca também não apresentaram correlação estatisticamente significante com a posição do disco. Apenas a dor muscular à palpação foi associada a abertura de boca (p<0,05). Conclui-se que não há associação entre sinais e sintomas clínicos e posição do disco com a posição da cabeça de mandíbula em pacientes portadores de DTM...


The association between signs and symptoms of temporomandibular disorders (TMD) and findings on magnetic resonance imaging (MRI) has been controversial, thus, this study evaluated the disc position, by the clock method, and verified the association with the condyle position, muscle pain on palpation, passive and active opening, presence of temporomandibular joint (TMJ) sound and age in patients with TMD who underwent MRI. The disc position was classified as 0 - normal position (posterior band at 11 and 12 hours); 1 - mild displacement (position between 11 and 10 hours); 2 - Moderate displacement (position between 10:09 hours); and 3 - Severe displacement (position 9 to 8 hours). The condyle position was graded according to the Pullinger's method as 1 - posterior; 2 - anterior; and 3 - concentric. Three examiners performed the analyses. The association between clinical and imaging data was performed using the intraclass correlation coefficient ICC -, Spearman correlation coefficient, analysis of variance, Fisher's exact test or Kruskal-Wallis test as appropriate, with 5% significance level. Sixty cases were included in the study, with a predominance of women and average age of 37. There was excellent agreement between the examiners to disc and condyle position, but there was no significant correlation between these two variables. The presence of TMJ sound, muscle pain on palpation and range of mouth opening also showed no statistically significant correlation with the disc position. Only muscle pain on palpation was associated with mouth opening (p <0.05). It is concluded that there is no association between clinical signs and symptoms and disc position with condyle position in patients with TMD...

ABSTRACT

A Disfunção Temporomandibular (DTM) é um termo que remete ao conjunto de doenças que envolvem músculos mastigatórios, articulação temporomandibular (ATM) e estruturas associadas. Diversos estudos buscam uma ligação entre sinais e sintomas de pacientes com DTM, tentando correlacionar o posicionamento de estruturas anatômicas, especificamente disco articular e cabeça da mandíbula, com a presença de dores nas ATMs, nos músculos mastigatórios e posturais. No que se refere à posição da cabeça da mandíbula na fossa mandibular, a literatura relata existir uma grande variação, sendo que os conceitos de normalidade e anormalidade são controversos. Os estudos sobre DTM evoluíram ao longo dos anos, principalmente nas últimas três décadas, graças ao advento de técnicas de exames de imagem como a Tomografia Computadoriza (TC) e a Ressonância Magnética (RM). Atualmente a RM é considerada o melhor método de avaliação de imagem para se estudar a ATM, tanto nos aspectos anatômicos e fisiológicos de normalidade, quanto nos aspectos patológicos, complementando o exame clínico de pacientes com DTM. O objetivo principal desse estudo foi a comparação do método de Pullinger-Hollender (P-H) com o método de Gelb quanto à posição da cabeça da mandíbula (anterior, concêntrica ou posterior) avaliada no exame de ressonância magnética (cortes centrais sagitais ponderados em T1) de 60 pacientes (42 mulheres e 18 homens) diagnosticados com DTM...


The term Temporomandibular Disorder (TMD) refers to the group of diseases that involves the masticatory muscles, temporomandibular joint (TMJ) and associated structures. Several studies have sought a link between signs and symptoms of TMD patients, trying to correlate the position of anatomical structures, specifically articular disc and condyle, with the presence of pain in the TMJ, masticatory and postural muscles. As regards the position of the condyle in the articular fossa, the literature reports a wide variation and the concepts of normality and abnormality are controversial. Nevertheless, the methods described to measure this placement do not follow a pattern. Studies on DTM have evolved over the years, especially in the last three decades, thanks to the advent of techniques of imaging tests such as Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). MRI is currently considered the best method of imaging evaluation to study the TMJ both anatomical and physiological aspects of normality as the pathological aspects, complementing the clinical examination of patients with TMD. The main objective of this study was to analyze the position of the condyle in the articular fossa (anterior, posterior or concentric) using comparison of the PullingerHollender method (PH) with the Gelb method evaluated the MRI (sagittal central sections T1- weighted) 60 patients (42 women and 18 men) diagnosed with TMD. The secondary objective was to evaluate the inter-judge agreement in the application of the two methods. Each judge reproduced two drawings of each selected interval of 30 days between them, which were placed in four separate envelopes cut and later was chosen randomly one of them, the rest were discarded...

Objetivo: Describir las características clínicas de los pacientes con desórdenes temporomandibulares del Hospital de San José. Materiales y métodos: Serie de casos. Se incluyeron los pacientes con diagnóstico de desórdenes temporomandibulares durante junio del 2010 a junio del 2013. Resultado: Se identificaron 284 registros, con un promedio de edad de 41,5 años (DE 17,3). El 81,7% eran mujeres. El síntoma reportado con mayor frecuencia por el paciente fue dolor, con el 86,6%. La media de apertura oral fue 3,8 cm (DE 0,7). La resonancia magnética constituyó el examen más solicitado, con el 16,5%. El tratamiento médico más indicado fue la combinación de placa miorrelajante, dieta blanda y terapia térmica, con el 57%. El 18,6% de los pacientes con disfunción temporomandibular requirieron manejo quirúrgico. Conclusión: Al describir las características de los pacientes con desórdenes temporo-mandibulares en el Servicio de Cirugía Maxilofacial del Hospital de San José, en el periodo de junio del 2010 a junio del 2013, se puede concluir que el sexo que más presenta esta patología es el femenino, en mayores de 40 años, posiblemente por alteraciones oclusales debidas a mala adaptación protésica o ausencia de piezas dentales, estrés, presencia de hábitos parafuncionales asociados a posibles cambios artrósicos por la edad...


Temporomandibular joint disorders are the most frequent cause of non-dental orofacial pain. They are characterized by pain and mastication system dysfunction. Objective: To describe the clinical characteristics of patients with temporomandibular joint disorders at Hospital de San José. Materials and methods: Case series. Patients diagnosed with temporomandibular joint disorders between June 2010 and June 2013 were included. Results: Overall, 284 records were identified of patients with a mean age 41.5 years (SD 17.3). Of those, 81.7% were women. The most frequent symptom reported by the patients was pain (86.6%). Mean oral opening was 3.8 cm (SD 0.7). Nuclear magnetic resonance was the most requested study (16.5%). The medical treatment most frequently indicated was a combination of splint, soft diet and thermal therapy (57 %). Of the patients with temporomandibular dysfunction, 18.6% required surgical management. Conclusion: Based on the description of the characteristics of patientes with temporomandibular joint disorders coming to the Maxillofacial Surgery Service at Hospital de San José, between June 210 and June 2013, it may be concluded that this disorder is more frequent in the female gender and in people over 40. This may be explained perhaps by the occlusion abnormalities due to poor prosthetic fitting or absence of teeth, stress, or habitus associated with potential age-related arthrosis changes...

ABSTRACT

La alteración en el normal funcionamiento de la Articulación Temporomandibular (ATM), puede tener repercusiones en forma aguda o crónica, con especial énfasis en los músculos de la masticación y/o inflamación de la articulación, que conecta la mandíbula con el cráneo. La principal causa es la hiperfunción o parafunción muscular, como en el caso del bruxismo, con repercusión en el sistema musculo-esqueletal de la cavidad oral, como también diferentes tipos de desplazamientos del disco en la ATM. El desorden trasciende los límites entre diferentes disciplinas de la salud, en particular, odontología y neurología que tienen diferentes enfoques de tratamiento. La ATM es susceptible a muchas otras afecciones que afectan a otras articulaciones del cuerpo, incluyendo anquilosis, artritis, trauma, luxaciones, desarrollo de anomalías, neoplasias y lesiones recidivantes. La decisión para intervenir una ATM debería ser tomada con cautela y basada en un análisis racional y apropiado de la enfermedad subyacente. En csos selectos, la cirugía de ATM es el tratamiento de elección para un subconjunto de desordenes Temporomandibulares, incluyendo trastornos articulares internos, enfermedad degenerativa de la articulación, artritis reumatoide, artritis infecciosa, luxación mandibular, anquilosis e hiperplasia o hipoplasia condilar. El objetivo del presente trabajo es enmarcar la cirugía de ATM como un ámbito indiscutible de la cirugía oral y maxilofacial, que bajo un diagnóstico certero y criterio quirúrgico apropiado lleva a una resolución definitiva del cuadro patológico.


Temporomandibular joint disorder a term covering acute or chronic pain, especially in the muscles of mastication and/or inflammation of the temporomandibular joint, which connects the mandible to the skull. The primary cause is muscular hyper or parafunction, as in the case of bruxism, with secondary effects on the oral musculoskeletal system, like various types of displacement of the disc in the temporomandibular joint. The disorder transcends the boundaries between several health-care disciplines in particular, dentistry and neurology there are a variety of treatment approaches. The temporomandibular joint is susceptible to many of the conditions that affect other joints in the body, including ankylosis, arthritis, trauma, dislocations, developmental anomalies, enoplasia and rective lesions. The decision to perform temporomandibularjoint (TMJ) surgery should be made carefully and must be based on a rational and appropiate analysis of the underlying disease. In selected cases, TMJ surgery is the preferred treatment for a subset of temporomandibular disorders (TMDs), incluiding internal derangement, degenerative joint disease, rheumatoid arthritis, infectious arthritis, mandibular dislocation, ankylosis, and condylar hyperplasia or hypoplasia. The aim of this article is to establish that TMJ surgery is the undisputed purview of the maxillofacial surgeon, thatunder accurate diagnosis and adquate surgical criteria leads to a definitive resolution of the pathology.

ABSTRACT

A Disfunção Temporomandibular (DTM) se refere a várias doenças que envolvem os músculos da mastigação e/ou a articulação temporomandibular (ATM). Os distúrbios de desarranjo do disco são considerados uma subdivisão dos distúrbios intra-articulares da ATM e são aqueles onde há relacionamento anormal do disco articular com a cabeça da mandíbula, fossa articular e eminência articular. O procedimento para diagnosticar a DTM geralmente consiste em exame clínico, mas quando informações adicionais são necessárias para confirmar esse resultado, exames de imagem são solicitados. Imagem por ressonância magnética (IRM) é considerada o exame padrão-ouro de referência de diagnóstico não invasivo de deslocamento de disco. Na literatura revisada não há justificativa de que o corte central da IRM deva ser o utilizado para classificar o posicionamento do disco e talvez o uso de vários cortes da IRM pudesse fornecer um dado importante para uma correta interpretação da posição do disco. O presente estudo avaliou a concordância entre três avaliadores para ambos os critérios de classificação (corte central versus vários cortes); verificou a concordância entre os dois critérios, além de correlacionar os resultados obtidos por ambos os critérios com o sinal clínico de estalo em pacientes diagnosticados com DTM. Para medir os níveis de concordância das proporções de imagens deslocadas entre os três avaliadores foi utilizado o coeficiente de correlação intraclasse (ICC). Os níveis de concordância entre os métodos e entre as avaliadoras foram medidos através do método Kappa. O teste utilizado para verificar associações entre as variáveis foi o teste exato de Fisher bicaudal e o nível de significância adotado foi de 0,05. Do total de pacientes examinados 70% (42/60) eram do sexo feminino e 30% (18/60) do sexo masculino


A média de idade foi de 37,2 ± 12,5, Mensurando a concordância entre os avaliadores para os critérios diagnósticos do posicionamento do disco articular da ATM o ICC obtido foi excelente (0,839) para o critério que considerou a proporção de discos deslocados. Para o critério de pelo menos um disco deslocado um Kappa substancial de 0,795 foi alcançado e para o critério do corte central um Kappa de concordância quase perfeita de 0,806 foi encontrado. Um Kappa alto (0,815) também foi atingido na concordância da classificação do posicionamento do disco na IRM em abertura. Após os critérios de avaliação para a posição do disco serem submetidos aos testes estatísticos para a averiguação entre a concordância deles, um Kappa de concordância substancial de 0,697 foi constatado. Notou-se nesse estudo que existe uma associação entre o estalo e a classificação com o disco deslocado pelo método da corte central (p=0,01) e entre o diagnóstico de deslocamento do disco articular obtido através da IMR em abertura da ATM e o estalo (p=0,011). Não foi encontrada associação entre o estalo articular e a posição do disco articular pelo critério de vários cortes


The Temporomandibular Dysfunction (TMD) refers to several diseases related to the muscles involved in chewing and/or the temporomandibular joint (TMJ). The articular disc derangement disorders are considered a subdivision of TMJ intra-articular disorders and are the ones on which there is an abnormal relationship between the joint disc, the condyle (head of the jaw), the articular fossae and the articular eminence. The procedure to diagnose temporomandibular dysfunction consists of five clinical examinations, but when additional information becomes necessary to confirm the results, image techniques are required. Magnetic Resonance Imaging (MRI) is considered the golden standard technique and is the reference for non-invasive diagnosis of disc displacement. In the literature review it is not conclusive that the central slice of the MRI must be used to classify the disc position, and it is possible that the use of several slices of MRI could provide important data for a more appropriate interpretation of the disc position. This study compared the agreement of the findings between three analyzers for both classification criteria (central slice and several slices); verified the agreement between the two criteria, as well as correlated the obtained results for both criteria with the clinical sign of clicking in patients diagnosed with TMD. In order to measure the agreement of the displacement image proportions between the three analyzers, the interclass correlation coefficient (ICC) was used. The degrees of agreement between the analyzers were measured with the Kappa method. The test used to verify the association between the variables was the two-tailed Fischer exact test and the adopted level of significance was 0.05. From the total patients examined, 70% (42/60) were females and 30% (18/60) were males


The average age was 37,2 ± 12,5. The measurements for the agreement between the analyzers for the diagnosis criteria of the joint disc position of the TMJ resulted in an excellent ICC (0,839) for the criteria that considered the disc displacement proportions. For the criteria of at least one displaced disc, a substantial Kappa of 0,795 was reached, and for the criteria of central slice an almost perfect Kappa agreement of 0,806 was reached. A high Kappa (0,815) was also obtained in the agreement of the disc placement classification in the opened mouth MRI. After the criteria of analysis for disc position were submitted to statistical tests for validation of the agreement between them, a Kappa of substantial agreement of 0,697 was registered. It was observed in this study that there exists an association between clicking and the classification of disc displacement by the central slice method (p=0,01) as well as between the joint disc displacement diagnosis obtained through the opened mouth MRI of the TMJ and the clicking (p=0,011)
