A new biofeedback approach for the control of awake bruxism and chronic migraine headache: utilization of an awake posterior interocclusal device / Uma nova abordagem via biofeedback para o controle do bruxismo de vigília e de enxaqueca crônica: utilização de um dispositivo interoclusal posterior em vigília

ABSTRACT Background: The relationship of bidirectional comorbidity between chronic migraine and pain in the cephalic segment led us to evaluate the improvement in reducing the pain in patients diagnosed with chronic migraine headache and awake bruxism, when undergoing treatment with a partial posterior interocclusal device designed for the management and control of awake bruxism through biofeedback. Methods: Seventy-four patients were evaluated during the following periods: pretreatment, seven, thirty, ninety, one hundred and eighty days, and one year. The evaluation was carried out by measuring the pain in the pretreatment period and pain reduction after awake bruxism treatment, using clinical evaluation and numerical scales for pain. Results: Most of the patients who complained of headache migraine pain, masticatory myofascial pain, temporomandibular joint and neck pain experienced a significant reduction in overall pain, including headaches, between t0 and t30 (p<0.0001). After 30 days of using the device, it was observed that the improvement remained at the same level without any recurrence of pain up to t90. At t180 and t360, it was observed that even with the device withdrawal (at t90) the improvement remained at the same level. Conclusion: The utilization of a posterior interocclusal device designed for the management and control of awake bruxism through biofeedback seems to contribute to the reduction of pain (including migraine headache) in the majority of patients, and, even with the device withdrawal (at t90), the improvement remained at the same level, suggesting the patients succeeded in controlling their awake bruxism and consequently the pains.

RESUMO Introdução: A relação de comorbidade bidirecional entre enxaqueca crônica e dor no segmento cefálico nos levou a avaliar a melhora na redução da dor em pacientes diagnosticados com cefaleia crônica de enxaqueca e bruxismo de vigília, quando submetidos a tratamento com dispositivo interoclusal posterior parcial projetado para o manejo e o controle do bruxismo acordado através de biorretroalimentação (biofeedback). Métodos: Setenta e quatro pacientes foram avaliados durante os seguintes períodos: pré-tratamento, sete, trinta, noventa e cento e oitenta dias, e um ano. A avaliação foi realizada por meio da avaliação da dor no período pré-tratamento e redução da dor após o tratamento do bruxismo de vigília, através de avaliação clínica e escalas numéricas de dor. Resultados: A maioria dos pacientes que se queixou de dor de cabeça com enxaqueca, dor miofascial mastigatória, articulação temporomandibular e dor no pescoço sofreu uma redução significativa na dor geral, incluindo dores de cabeça, entre t0 e t30 (p<0,0001). Após 30 dias de uso do dispositivo, observou-se que a melhora permaneceu no mesmo nível, sem recorrência da dor até t90. Em t180 e t360, observou-se que, mesmo com a retirada do dispositivo (em t90), a melhoria permaneceu no mesmo nível. Conclusão: A utilização de um dispositivo interoclusal posterior projetado para o controle do bruxismo de vigília através de biofeedback parece contribuir para a redução da dor (incluindo enxaqueca) na maioria dos pacientes, e, mesmo com a retirada do dispositivo (t90), a melhora manteve-se no mesmo nível, sugerindo que os pacientes conseguiram controlar o seu bruxismo de vigília e a dor associada a esse hábito.

The Role of Magnetic Resonance Imaging of the Temporomandibular Joint to Investigate Tinnitus in Adults with Temporomandibular Joint Disorder: A Comparative Study

Abstract Introduction The prevalence of tinnitus is higher in individuals with temporoman- dibular joint disorder (TMD) than in the general population. Magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) is the method of choice for investigation, and it has been hypothesized that specific MRI findings might be observed in TMD with comorbid tinnitus. Objective To comparatively describe MRI findings in patients with TMD with and without tinnitus, identifying the most common TMJ alterations and determining whether a correlation exists between severity of TMD and tinnitus. Methods A cross-sectional study of 53 adult patients with bilateral or unilateral TMD (30 with and 23 without tinnitus). The association between tinnitus and morphological aspects of TMD (changes in condylar morphology, articular eminence morphology, and disc morphology), disc displacement (with/without reduction), condylar translation, and intra-articular effusion was analyzed on MRI images. Results The mean patient age was 46.12 ± 16.1 years. Disc displacement was the most common finding in both groups (24 patients with tinnitus versus 15 without; p = 0.043). Only the frequency of disc displacement with reduction was significantly different between groups. Conclusion Additional imaging techniques should be explored to detect specific aspects of the relationship between tinnitus and TMD.

Implementation of TMD pain screening questionnaire in peruvian dental students / Implementacion de un cuestionario de triaje para trastornos temporomandibulares asociados al dolor en estudiantes de odontologia peruanos

The aim of this study was to screen for painful TMD conditions by implementing the validated Axis I screening instrument from the Diagnostic Criteria for Temporomandibular Disorders. Using the screener as a surrogate, the prevalence of the conditions was estimated among a convenience sample of dental students in Peru. A total 2,562 dental students, 63.7% women, aged 18 to 62 completed the instrument. Prevalence was estimated using both the short and long versions. The prevalence of painful TMD conditions was 19.4% with the short and 16.1% with the long version. The distribution of the conditions according to gender differed significantly between groups (p<.001). Prevalence estimates of painful TMD conditions using the screening instrument seems to be logistically adequate in a field assessment involving multiple geographic and cultural regions in Peru. These estimates seem to be consistent with internationally reported values.

El objetivo de este estudio fue tener una estimación de las condiciones de los trastornos temporomandibulares asociados al dolor, mediante la implementación de un instrumento validado de triaje para la medición del Eje I de los Criterios Diagnósticos para los Trastornos Temporomandibulares (CD/TTM). Usando este instrumento como un sustituto, se estimó la prevalencia de estas condiciones en una muestra por conveniencia de estudiantes de Odontología en el Perú. Un total de 2,562 estudiantes de Odontología, 63.7% mujeres, entre las edades de 18 a 62 años de edad, completaron el instrumento. La prevalencia fue estimada empleando las versiones corta y larga del instrumento. La prevalencia de los TTM asociados al dolor fue de 19.4% con la versión corta y 16.1% con la versión larga. La distribución de estas condiciones fue estadísticamente diferente según el sexo (p<.001). El empleo del instrumento de triaje para estimar la prevalencia de los TTMs asociados al dolor parece ser logísticamente adecuado en un escenario de diversas regiones geográficas y culturales en el Perú. Estas estimaciones parecen ser consistentes con valores internacionalmente reportados.

Painful temporomandibular disorder, sleep bruxism, anxiety symptoms and subjective sleep quality among military firefighters with frequent episodic tension-type headache. A controlled study / Desordens temporomandibulares dolorosas, bruxismo do sono, sintomas de ansiedade e qualidade subjetiva do sono em bombeiros militares com cefaleia do tipo tensional episódica frequente. Estudo controlado

ABSTRACT Objective To investigate associations of temporomandibular disorders (TMDs), bruxism, anxiety and sleep quality among military firefighters with frequent episodic tension-type headache (FETTH). Methods The sample comprised two groups (80 individuals): controls (mean age 35.2 years) and study group (mean age 38.5 years). Headache was diagnosed in accordance with the ICHD-III. The Research Diagnostic Criteria for TMDs were used to classify the TMDs; bruxism was diagnosed in accordance with the International Classification of Sleep Disorders; anxiety was classified using the Beck Anxiety Inventory; and sleep quality was assessed using the Pittsburgh Sleep Quality Index. In the statistical models, we used a significance level of 95%. Results Associations were found between participants with FETTH and TMDs (p < 0.001) and anxiety (p = 0.002).Poor quality of sleep (p = 0.687) and bruxism (p = 0.670) were not risk factors. Conclusion The study found that TMDs and anxiety among firefighters were associated with FETTH.

RESUMO Objetivo Investigar associações de distúrbios temporomandibulares (DTM), bruxismo, ansiedade e qualidade subjetiva do sono entre bombeiros militares com cefaleia do tipo tensional episódica frequente (CTTEF). Método A amostra consistiu em dois grupos com 80 indivíduos cada: controles (idade média 35,2 anos) e grupo de estudo (idade média 38,5 anos). A dor de cabeça foi diagnosticada de acordo com a Classificação Internacional de Cefaleias, 3a edição. Os critérios de diagnóstico de pesquisa para DTM (RDC / TMD) foram utilizados para classificar DTM; o bruxismo foi diagnosticado de acordo com a Classificação Internacional de Distúrbios do Sono; a ansiedade foi classificada usando o Inventário de Ansiedade Beck; e a qualidade do sono foi avaliada usando o Índice de Qualidade do Sono de Pittsburgh (PSQI). Nos modelos estatísticos utilizamos um nível de significância de 95%. Resultados Foram encontradas associações entre indivíduos com CTTEF e presença de DTM (p <0,001) e ansiedade (p = 0,002). A baixa qualidade do sono (p = 0,687) e o bruxismo (p = 0,670) não foram fatores de risco para CTTEF. Conclusão O estudo verificou que DTM e ansiedade entre os bombeiros estavam associados a CTTEF, mas a qualidade subjetiva do sono e o bruxismo não foram fatores de risco.

Toxina Botulínica para el Tratamiento de los Desórdenes Temporomandibulares / Botulinum Toxin for the Treatment of Temporomandibular Disorders

RESUMEN: Los Trastornos Temporomandibulares (TTM) consisten en un conjunto de condiciones patológicas que afectan la articulación temporomandibular (ATM), los músculos de la masticación y las estructuras asociadas. Estudios epidemiológicos estiman que 40 % a 75 % de la población adulta presenta por lo menos un signo de TTM, como ruido articular y 33 % por lo menos un síntoma, como dolor facial o en la ATM. La toxina botulínica (BoNT) es una neurotoxina producida por la bacteria anaerobia Clostridium botulinum, solo la toxina A y B son utilizadas en la práctica clínica después de la aprobación de la Food and Drug Administration en 1989 y 2000; actualmente continúan siendo utilizadas para tratar varias condiciones de dolor, incluyendo la espasticidad muscular, distonia, dolor de cabeza y dolor miofascial. Las propuestas del mecanismo de acción fueron sugeridas a mediados de 1950 manifestando que esta neurotoxina posee alta afinidad con la sinapsis colinérgicas, ocasionando un bloqueo en la liberación de acetilcolina de esos terminales nerviosos, sin alterar la conducción neural de las señales eléctricas o en la síntesis de almacenamiento de acetilcolina. La inyección intramuscular en dosis y localización apropiada, provoca denervación química parcial y disminución de la contractura, sin ocasionar parálisis completa a lo que se le atribuye ser un innovador y eficaz método de tratamiento para el dolor crónico asociada con hiperactividad de los músculos masticatorios. La toxina botulínica tipo A es ser una alternativa para el control de la sintomatología dolorosa presente en los TTMs de etiología miogénica. Los autores recomiendan realizar un correcto diagnóstico, ya que la indicación de este tipo de tratamiento con diagnósticos incorrectos lleva a resultados inciertos.

ABSTRACT: Temporomandibular Disorders (TMD) is a term that was used to describe a set of pathological conditions that affect temporomandibular joint (TMJ), muscles of mastication and associated structures. Epidemiological studies estimates that 40 % to 75 % of the adult population has at least one sign of TMD, such as joint noise and 33 % presented some symptom such as facial or joint pain. Botulinum toxin is a neurotoxin produced by the anaerobic bacterium Clostridium botulinum. There are two types of toxin (A and B) used in clinical practice that were approved by Food and Drug Administration in 1989 and 2000. These medications are in use to treat various diseases including muscle spasticity, dystonia, headache and myofascial pain. The mechanisms of action were suggested in the mid-1950s, this neurotoxin seems to have an action at cholinergic synapses, causing a block in the release of acetylcholine from the nerve terminals without altering the neural conduction of the electrical signals. The synthesis and storage of acetylcholine were preserved. Intramuscular injection in appropriate doses and location causes partial chemical denervation and decreased contracture, without causing complete paralysis of muscles. Due to this features, it has been considered an innovative and effective method to treat chronic pain associated with hyperactivity of masticatory muscles. The botulinum toxin type A appears to be an alternative method for pain control present in TMDs that have myogenic etiology. The authors recommend a correct diagnosis, since the indication of this type of treatment associated with an incorrect diagnosis leads to uncertain outcomes, creating false conclusions.

Class II Division 2 subdivision left malocclusion associated with anterior deep overbite in an adult patient with temporomandibular disorder

ABSTRACT The orthodontic treatment of patients with chief complaint of temporomandibular disorders (TMD) presents doubtful prognosis, due to the poor correlation between malocclusions and TMDs. The present case report describes the treatment of an adult patient with Angle Class II Division 2 subdivision left malocclusion associated with anterior deep overbite and TMD. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO), as part of the requirements to obtain the title of BBO Diplomate.

RESUMO O tratamento ortodôntico de pacientes com queixa principal de disfunção nas articulações temporomandibulares (DTM) apresenta prognóstico duvidoso, devido à baixa correlação entre as más oclusões e as DTMs. O presente relato de caso descreve o tratamento de um paciente adulto com má oclusão de Classe II, divisão 2, subdivisão esquerda, de Angle e sobremordida profunda, associadas à DTM.

Influência da hipermobilidade articular generalizada sobre a articulação temporomandibular e a oclusão dentária: estudo transversal / Influence of generalized joint hypermobility on temporomandibular joint and dental occlusion: a cross-sectional study

RESUMO Objetivo Avaliar a oclusão dentária e a articulação temporomandibular de mulheres com e sem hipermobilidade articular generalizada. Método A hipermobilidade foi avaliada pelo Escore de Beighton, e as voluntárias foram distribuídas, conforme o escore obtido, em dois grupos: com e sem hipermobilidade. A articulação temporomandibular foi avaliada por meio do instrumento Critérios de Diagnóstico para Pesquisa de Desordens Temporomandibulares, e a avaliação oclusal compreendeu a classificação de Angle, presença de sobremordida, sobressaliência e mordida cruzada, padrão de desoclusão e interferências oclusais. Resultados 43 mulheres participaram voluntariamente da pesquisa, 17 no grupo com hipermobilidade e 26 no grupo sem hipermobilidade. A frequência de ruídos articulares e de desvio na abertura da boca foi maior no grupo com hipermobilidade (52,9% versus 38,5% e 76,5% versus 50%, respectivamente), sem diferença significante. Quanto à oclusão, nenhuma voluntária apresentou uma oclusão ideal e não se verificou diferença significativa na Classe de Angle entre os grupos. As alterações na oclusão obtiveram percentual maior no grupo com hipermobilidade (29,4% de sobremordida, 47,1% de sobressaliência e 17,6% de mordida cruzada), sendo que a mordida cruzada apresentou diferença estatística entre os grupos. Conclusão A hipermobilidade não influenciou a oclusão e as amplitudes de movimentos mandibulares nas mulheres avaliadas. Contudo, o maior percentual de ruídos articulares e de desvio não corrigido apresentado pelo grupo com hipermobilidade, mesmo sem diferença entre os grupos, pode constituir um indício de relação entre hipermobilidade e disfunção temporomandibular.

ABSTRACT Purpose To evaluate the dental occlusion and temporomandibular joint in women with and without generalized joint hypermobility. Methods Generalized joint hypermobility was assessed by the Beighton score. Individuals were divided into two groups: with and without hypermobility. The Research Diagnostic Criteria for Temporomandibular Disorders was used to evaluate the temporomandibular joint. Dental occlusion was assessed according to Angle classification, overjet and overbite measures, presence of open bite or crossbite, pattern of disocclusion, and occlusal interference. Results Forty-three women participated voluntarily in the study: 17 in the group with hypermobility and 26 in the group without hypermobility. The frequencies of joint noise and deviation during mouth opening were greater in the hypermobility group (52.9% vs. 38.5% and 76.5% vs. 50%, respectively), but without statistical significance. None of the volunteers presented ideal occlusion and no significant difference was found in Angle Class between the groups. The hypermobility group presented a higher percentage of changes in occlusion (29.4% of overbite, 47.1% of overjet, and 17.6% of crossbite), with crossbite showing statistical difference between the groups. Conclusion Hypermobility does not influence occlusion and range of mandibular motion in the women assessed. Nevertheless, the higher percentage of articular noise and uncorrected deviation during mouth opening shown by the group with hypermobility, even without statistical difference, may constitute evidence of correlation between hypermobility and temporomandibular disorder.

Occlusal changes secondary to temporomandibular joint conditions: a critical review and implications for clinical practice

ABSTRACT The relationship between Temporomandibular Disorders (TMD) and malocclusion is an extremely critical issue in dentistry. Contrary to the old concept that malocclusion causes TMD, occlusal changes, especially those observed as sudden, may be secondary and reflect joint or muscle disorders due to the obvious connection between these structures and the dental occlusion. Objectives The aim of this article is to present the most commonly occlusal changes secondary to TMD. Methods The clinical presentation of these conditions is discussed. Details regarding diagnosis, treatment, and follow-up of patients presenting TMD prior or during treatment are also presented. Conclusions All plans for irreversible therapy should be preceded by a meticulous analysis of TMD signs and symptoms in such a way that patients are not submitted to irreversible treatment, based on an untrue occlusal relationship, secondary to articular and/or muscular disorders. When present, TMD symptoms must always be controlled to reestablish a “normal” occlusion and allow proper treatment strategy.

Temporomandibular disorders in fibromyalgia patients: are there different pain onset? / Disfunção termomandibuar em doentes com fibromialgia: há diferença no início das dores?

ABSTRACT Objective To identify temporomandibular disorders (TMD) symptoms in two groups of fibromyalgia patients according to the temporal relation between the onset of facial pain (FP) and generalized body pain (GBP). Cross-sectional study design: Fifty-three consecutive women with fibromyalgia and FP were stratified according to the onset of orofacial pain: Group-A (mean age 47.30 ± 14.20 years old), onset of FP preceded GBP; Group-B (mean age 51.33 ± 11.03 years old), the FP started concomitant or after GBP. Clinical assessment Research Diagnostic Criteria for Temporomandibular Disorders and the Visual Analogue Scale. Results Myofascial pain with mouth opening limitation (p = 0.038); right disc displacement with reduction (p = 0.012) and jaw stiffness (p = 0.004) were predominant in Group A. Myofascial pain without mouth opening limitation (p = 0.038) and numbness/burning were more common in Group B. Conclusion All patients had temporomandibular joint symptoms, mainly muscle disorders. The prevalence of myofascial pain with limited mouth opening and right TMJ disc displacement with reduction were higher in Group A.

RESUMO Objetivo Identificar sintomas de disfunção temporomandibular (DTM) em dois grupos de pacientes fibromiálgicas, segundo a relação temporal entre o início da dor facial (DF) e das dores generalizadas no corpo (DGC). Estudo transversal: 53 pacientes consecutivas com fibromialgia e DF foram divididas de acordo com o início da dor orofacial: Grupo A (média de idade 47,30 ± 14,20anos), o início da DF precedeu o da DGC; Grupo-B (idade média 51,33 ± 11,03anos), a DF iniciou concomitantemente ou após a DGC. Avaliação clínica: Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) e escala visual analógica (EVA). Resultados Dor miofascial com limitação de abertura bucal (p = 0,038); deslocamento de disco à direita com redução (p = 0,012) e rigidez mandibular (p = 0,004) foram predominantes no Grupo A. Dor miofascial sem limitação de abertura bucal (p = 0,038) e dormência/queimação foram mais comuns no Grupo-B. Conclusão Todos os pacientes tiveram sintomas de DTM, principalmente disfunção muscular. A prevalência de dor miofascial com limitação de abertura bucal e deslocamento de disco à direita com redução foi maior no Grupo A.

Baropodometria dinâmica de atletas remadores, com sinais e sintomas de disfunção temporomandibular, pré e pós tratamento, com placa oclusal estabilizadora e exercício terapêutico de movimento mandibular: estudo piloto / Dynamic baropodometry in rowing athletes refering signs and symptoms of temporomandibular joint dysfunction before and after using an occlusal splint associated to therapeutic mandibular exercise: pilot study

A desordem temporomadibular em atletas da modalidade do remo é uma temática ainda pouco abordada na literatura, muito embora se tenha conhecimento que a biomecânica do gesto esportivo possa provocar dores lombares, fratura de costela devido ao estresse, além de dores cervicais provenientes do desprendimento de força, para atingir grande velocidade e manutendo o equilíbrio por um longo tempo. O presente estudo tem como objetivo analisar, por meio da baropodometria dinâmica, a ação da placa oclusal estabilizadora associada ao exercício terapêutico de movimento mandibular em atletas remadores diagnosticados como portadores de desordem temporomandibular (DTM). Estudos prévios demonstram que um dispositivo intraoclusal (placa oclusal estabilizadora) tem ação significante sobre o sistema de manutenção do equilíbrio corporal na postura estática. Trinta indivíduos remadores apresentaram-se como voluntários com queixa de dor, sendo 10 deles (40% homens e 60% mulheres), com idade entre 24 e 35 anos foram diagnosticados com DTM por meio do preenchimento do questionário RDC/TMD e de exame clínico. O presente estudo piloto foi caracterizado por ser um ensaio clínico, randomizado, controlado, prospectivo e de intervenção. Imediatamente após aplicação do questionário e do exame clínico, todos os indivíduos realizaram testes de

baropodometria estática e dinâmica. Após esta etapa, realizou-se a randomização dos grupos por meio de software online gratuito (www.random.org) que determinou os integrantes do grupo controle, denomindado de Grupo Exercício (GE) e grupo teste denominado de Grupo Placa (GP). Ambos os grupos receberam orientação para a realização do exercício terapeutico de movimento mandibular. Definidos os integrantes do GP, foram realizados agendamento para a realização da etapa de confecção da placa oclusal. Os grupos foram monitorados por 12 semanas e após este período foram reavaliados segundo os mesmos parâmetros da etapa inicial. A análise estatísitca foi realizada utilizando o modelo ANOVA (normalidade e homoscedasticiodade),teste T-Student e teste não paramétrico de Wilcoxon. Os resultados apresentaram significância estatística na redução da dor e aumento da amplitude articular da articulação temporomandibular (ATM) no GP (p<0,05). Não foi observada significância estatísitica na análise da pressão plantar dinâmica, justificado pelo fato da insuficiência do número de invidíduos da amostra. Concluiu-se que o uso da placa oclusal foi eficaz no tratamento da DTM pela redução do quadro doloroso, entretanto, uma amostragem maior se faz necessária pra a verificação da integração entre sistema estomatognático e postural na dinâmica da marcha.

Temporomadibular joint disorder (TMJD) in rower athletes has still few studies over this theme, where the biomechanics of athletic gesture points can produce low back pain, rib stress fractures and cervical pain as resulting from power requirement to obtain high speed and body balance for repeatedly long period exercises. The aim of this study was to analyze through dynamic plantar pressure the effects of occlusal splint and therapeutic exercise of mandibular movement in rowers diagnosed as suffering from TMJD. Previous studies have shown that the occlusal splint has significant action to keep the system of body balance in standing position. 30 rower athletes came as volunteers with pain symptoms, and 10 individuals, 40% men ande 60% women, aged between 24 and 35 years, were diagnosed with TMJD through completion of the RDC/TMD questionnaire and clinical examination. The research was performed by a randomized controlled prospective clinical study besides intervention. Immediately after the questionnaire application and clinical examination, all individuals performed tests of static and dynamic baropodometry. After this procedure, the groups were randomized by using a free online software (www.random.org) which determined the

members of control group, named Exercise Group (EG) and test group called Oclusal Splint Group (OSG). Both groups received guidance for performing only therapeutic exercise of mandibular movement. The OSG were scheduled for the completion of preparation stage for occlusal splint. All groups were monitored for 12 weeks and after this period were evaluated according to the same parameters of the initial step. Statistic analysis was performed by using ANOVA model (normal and homoscedasticity), t-Student test and Wilcoxon nonparametric test. The results showed statistical significance to pain relief and increase of amplitude range of jaw joint in OSG (p < 0.05). No statistical significance was observed in the analysis of dynamic plantar pressure, justified by insufficient statistic population. In conclusion the use of occlusal splint was effective in the treatment of TMJD to pain relief, however, a larger sampling is necessary to verify the integration among stomatognatic system, posture and and gait dynamics analyzes.

Evaluation and Management of Occlusal Disturbances among Temporomandibular Disorders Patients: A Report of Two Cases.

Th e occlusal interference is considered as contributing factor in temporomandibular disorders. It has a strong association with occlusal interferences causing occlusal disturbances leading to orthopedic instability of temporomandibular joint. Digital evaluation should be made to eliminate the premature contacts of the teeth and to establish the harmonious, functional occlusion. T-scan is a grid-based sensor technology and occlusal system that allows an easier and more accurate way to measure occlusal timing and the force. Th ese two case reports explains the steps involved in the correction of chronic myofacial pain dysfunction and premature occlusion of teeth with balancing side interferences, which are highly destructive for joint and teeth structure due to the amount and direction of force generated in temporomandibular patients.

Temporomandibular disorder and anxiety, quality of sleep, and quality of life in nursing professionals

To evaluate the association between temporomandibular disorder (TMD) and anxiety, quality of sleep, and quality of life in nursing professionals at theHospital de Clínicas de Uberlândiaof theUniversidade Federal de Uberlândia – HCU-UFU (Medical University Hospital of the Federal University of Uberlândia), four questionnaires were given to nursing professionals. The questionnaires were completed by 160 of these professionals. The Fonseca’s questionnaire was used to evaluate the presence and severity of TMD, the IDATE was used to evaluate anxiety, the SAQ was used to evaluate quality of sleep, and the SF-36 was used to evaluate quality of life. Forty-one nurses (25.6%) reported having no TMD (Fonseca’s questionnaire score ≤ 15), 66 (41.3%) had mild TMD (Fonseca’s questionnaire score 20–40), 39 (24.4%) had moderate TMD (Fonseca’s questionnaire score 45–65), and 14 (8.8%) had severe TMD (Fonseca’s questionnaire score ≥ 70). According to Fonseca’s questionnaire, the presence of TMD was associated with trait anxiety, but the TMD severity was associated with state anxiety classification (mild, moderate, severe). The SAQ score differed significantly from Fonseca classification. The Fonseca’s questionnaire score correlated negatively with the score of each dimension of the SF-36 (r = –0.419 to –0.183). We conclude that TMD is common among nursing professionals; its presence was associated with trait anxiety, and its severity was associated with state anxiety. Hence, the presence of TMD may reduce quality of sleep and quality of life.

Influence of craniomandibular and cervical pain on the activity of masticatory muscles in individuals with Temporomandibular Disorder / Influência da dor craniomandibular e cervical na atividade dos músculos mastigatórios em indivíduos com Disfunção Temporomandibular

Purpose: This study aimed to establish the prevalence of pain in the craniomandibular and cervical spine region in individuals with Temporomandibular Disorders (TMD) and to analyze the effects of these disorders on the bilateral activation of anterior temporalis (AT) and masseter (MA) muscles during the masticatory cycle. Methods: The participants were 55 female volunteers aged 18–30 years. The presence of TMD and craniomandibular and cervical spine pain was evaluated by applying the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire and using a combination of tests for the cervical region. The muscle activity of AT and MA during the masticatory cycle was assessed using the symmetry and antero-posterior coefficient indices. Results: The AT activity during the masticatory cycle is more asymmetric in individuals with TMD. The craniomandibular pain, more prevalent in these individuals, influenced these results. Conclusion: Individuals with TMD showed changes in the pattern activity of AT. The craniomandibular nociceptive inputs can influence the increase in asymmetry of the activation of this muscle. .

Objetivo: O objetivo deste estudo foi determinar a prevalência de dor nas regiões craniomandibular e cervical em indivíduos com Disfunção Temporomandibular (DTM) e analisar o efeito dessas desordens na ativação bilateral dos músculos temporal anterior (TA) e masseter (MA) durante o ciclo mastigatório. Métodos: Participaram deste estudo 55 voluntários do sexo feminino com idade de 18 a 30 anos. A presença de DTM e de dor craniomandibular e cervical foi avaliada por meio do questionário Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) e uma combinação de testes para a região cervical. A análise da ativação muscular do TA e MA durante o ciclo mastigatório foi realizada através dos índices de simetria e do coeficiente anteroposterior. Resultados: A atividade dos músculos TA, durante o ciclo mastigatório, é mais assimétrica em indivíduos com DTM. A dor craniomandibular, mais prevalente nesses indivíduos, influencia nesses resultados. Conclusão: Indivíduos com DTM apresentam alteração no padrão mastigatório do músculo TA e estímulos nociceptivos da região craniomandibular podem influenciar no aumento da assimetria de ativação dessa musculatura. .

Temporomandibular disorders and eating disorders: a literature review / As desordens temporomandibulares e os transtornos alimentares: uma revisão de literatura

INTRODUCTION: Temporomandibular disorders (TMD) and eating disorders (ED) affect function and parafunction of the oral cavity and have high rates of medical and psychological comorbidity. However, little is known about the possible associations between them, and few studies have investigated the existence of such associations. METHODS: A search was conducted on the SciELO, LILACS, and PubMed/MEDLINE databases to find relevant articles written in English and Portuguese. Only studies involving human beings were included, and there was no limit for year of publication. RESULTS AND CONCLUSIONS: There is evidence of the correlation between TMD and ED, but their comorbidity must be better understood. The presence of depressive symptoms is an aggravating factor that must also be taken into account during the diagnosis and treatment of those patients (AU)

INTRODUÇÃO: As disfunções temporomandibulares (DTM) e os transtornos alimentares (TA) envolvem a função e a parafunção da cavidade oral e apresentam altos índices de comorbidade médica e psicológica. No entanto, pouco se sabe sobre as possíveis associações entre essas entidades clínicas, e poucos artigos avaliaram a existência de uma relação elas. MÉTODOS: Uma busca foi realizada nas bases de dados SciELO, LILACS e PubMed/MEDLINE a fim de encontrar artigos relevantes escritos em inglês e português. Apenas estudos envolvendo seres humanos foram incluídos, e não foi estabelecido um limite para ano de publicação. RESULTADOS E CONCLUSÕES: Há evidências da correlação entre DTM e TA, mas essa comorbidade precisa ser melhor compreendida. A presença de sintomas depressivos é um fator agravante que também precisa ser levado em consideração durante o diagnóstico e tratamento desses pacientes (AU)

Temporo-mandibular disorders are an important comorbidity of migraine and may be clinically difficult to distinguish them from tension-type headache / Desordens temporomandibulares sao comorbidade importante da migranea e podem ser clinicamente dificeis de distinguir da cefaleia tipo tensional

Clinical differentiation between the primary headaches and temporomandibular disorders (TMD) can be challenging. Objectives : To investigate the relationship between TMD and primary headaches by conducting face to face assessments in patients from an orofacial pain clinic and a headache tertiary center. Method : Sample consists of 289 individuals consecutively identified at a headache center and 78 individuals seen in an orofacial pain clinic because of symptoms suggestive of TMD. Results : Migraine was diagnosed in 79.8% of headache sufferers, in headache tertiary center, and 25.6% of those in orofacial pain clinic (p<0.001). Tension-type headache was present in 20.4% and 46.1%, while the TMD painful occurred in 48.1% and 70.5% respectively (p<0.001). Conclusion : TMD is an important comorbidity of migraine and difficult to distinguish clinically from tension-type headache, and this headache was more frequent in the dental center than at the medical center. .

A diferenciação clínica entre as cefaleias primárias e as disfunções temporomandibulares (DTM) pode ser desafiadora. Objetivos : Investigar a relação entre DTM e cefaleias primárias conduzindo uma avaliação face a face entre pacientes de um centro de dor orofacial e de um centro terciário de cefaleia. Método : A amostra consistiu de 289 indivíduos avaliados consecutivamente em um centro terciário de cefaleia e 78 indivíduos de uma clínica orofacial. Resultados : A migrânea foi diagnosticada em 79,8% dos pacientes do centro de cefaleia e 25,6% dos pacientes do centro de dor orofacial. A cefaleia do tipo tensional esteve presente em 20,4% e 46,1%, enquanto as DTM dolorosas ocorreram em 48,1% e 70,5% respectivamente (p<0,001). Conclusão : DTM é uma comorbidade importante da migrânea e difícil de distinguir clinicamente da cefaleia do tipo tensional, tanto que esta cefaleia foi mais frequente no centro odontológico do que no centro médico. .

Signs and symptoms of Temporomandibular Disorders in the elderly / Sinais e sintomas dos Transtornos Temporomandibulares em Idosos

Purpose: This study investigated the prevalence of Temporomandibular Disorders (TMD) in the elderly and its association with palpation of the temporomandibular joint (TMJ), masticatory and cervical muscles as well as the presence of headache and joint noises. Methods: The sample consisted of 200 elderly of both genders (mean age: 69.2±5.7 years). The clinical evaluation of TMD signs and symptoms was divided into three stages: an anamnestic questionnaire, a TMJ evaluation, and a muscular examination. The results were analyzed through descriptive statistics as well as using χ2 and the tendency tests. Results: The presence of TMD was observed in 61% of the sample (mild: 43.5%, moderate: 13%, severe: 4.5%). A significantly greater prevalence of TMD was found for females (72.4%) compared with that for men (41.1%) (p<0.0001). Additionally, a significant association among TMD severity and palpation of the TMJ (p=0.0168), of masticatory muscles (p<0.0001), and of cervical muscles (p<0.0001) was verified. Also, there was a significant association between the frequency of headaches and the presence of TMD (p=0.0001). The association between the presence of joint noises and sensitivity to TMJ palpation was not significant. Conclusion: The elderly presented high TMD prevalence, mostly in females, with mild severity and related to TMJ and masticatory/cervical muscles palpation. Thus, the accomplishment of a detailed clinical examination to investigate the presence of such disorders is essential and it must not be neglected during the treatment of elderly patients. .

Objetivo: O objetivo deste estudo foi investigar a prevalência de Transtornos Temporomandibulares (DTM) em idosos e sua associação com a palpação da articulação temporomandibular (ATM), dos músculos mastigatórios e cervicais, bem como com a presença de dores de cabeça e ruídos articulares. Métodos: A amostra foi composta por 200 idosos, de ambos os gêneros (média de idade: 69,2±5,7 anos). A avaliação clínica dos sinais e sintomas foi dividida em três etapas: aplicação de questionário anamnésico, avaliação da ATM e exame muscular. Os resultados foram avaliados por meio de estatística descritiva, teste do χ2 e teste de tendência. Resultados: A presença de DTM foi observada em 61% da amostra (leve: 43,5%, moderada: 13%, intensa/grave: 4,5%). Verificou-se prevalência significantemente maior de DTM para as mulheres (72,4%) em comparação aos homens (41,1%) (p<0,0001). Houve associação significante entre a severidade da DTM e a presença de dor à palpação da ATM (p=0,0168), dos músculos mastigatórios (p<0,0001) e cervicais (p<0,0001). Observou-se associação significante entre a frequência de dores de cabeça e a presença de DTM (p=0,0001). Não houve associação significante entre a presença de ruídos articulares e a sensibilidade à palpação da ATM. Conclusão: Os idosos apresentaram alta prevalência de DTM, em sua maioria no gênero feminino, de grau leve, relacionada à palpação na ATM e nos músculos mastigatórios e cervicais. Assim, é essencial a realização de um completo exame clínico para investigar a presença desses transtornos, especialmente durante o tratamento de idosos. .

Body posture changes in women with migraine with or without temporomandibular disorders / Alteracoes da postura corporal estatica de mulheres com migranea com e sem disfuncao temporomandibular

Background: Migraine and temporomandibular disorders (TMDs) are reported to be associated. However, there are no reports on the association among migraines, TMDs and changes in body posture. Objectives : To assess changes in body posture in women suffering migraines with or without TMD compared with a control group. Method: Sixty-six women with a mean age of 18 to 45 years participated in this study. The groups were composed of 22 volunteers with migraine and TMD (MTMD), 22 volunteers with migraines without TMD (MG) and 22 women in the control group (CG). Static posture was assessed by photogrammetry, and 19 angles were measured. Results: Postural asymmetry was observed in the face for 4 angles measured on the frontal plane in the MG group and for 4 angles of the trunk in the MG and MTMD groups with respect to CG. However, for comparisons between MTMD and CG, clinical relevance was identified for two angles of the sagittal plane (Cervical and Lumbar Lordosis, Effect Size - ES - moderate: 0.53 and 0.60). For comparisons between the MG and CG, the clinical relevance/potential was verified for three angles with moderate ES (ES>0.42). The clinical relevance when comparing MTMD and CG was identified for four angles of facial symmetry head inclination (ES>0.54) and for two angles between MG and CG (ES>0.48). Conclusion : The results demonstrated the presence of postural changes compared with a control group in women with migraines with or without TMD, and there were similar clinically relevant postural changes among the patients with migraines with and without TMD. .

Contextualização: Há relatos na literatura sobre associações entre migrânea e disfunção temporomandibular (DTM). Entretanto, não há relatos sobre a associação entre migrânea, DTM e alterações da postura corporal. Objetivos: Avaliar a presença de alterações da postura corporal em mulheres com migrânea com e sem DTM em relação a um grupo controle. Método: Foram avaliados três grupos de 22 integrantes cada, na faixa etária de 18 a 50 anos, sexo feminino, compostos de voluntárias com migrânea e DTM (GMDTM), migranosas sem DTM (GM) e grupo controle (GC). As voluntárias foram submetidas à avaliação da postura estática por meio da fotogrametria, e foram mensurados 19 ângulos. Resultados: Foram observadas assimetrias posturais em quatro ângulos mensurados no plano frontal na face no GM e em quatro ângulos do tronco no GM e no GMDTM em relação ao GC. Entretanto, foi verificada relevância clínica para dois ângulos posturais no plano sagital (GM vs. GMDTM - lordose cervical e lombar, Effect size - ES moderados: 0,53 e 0,60) e, para comparação entre o GM e o GC, foi observada relevância clínica/potencial para três ângulos (ES>0,42). Foi verificada relevância clínica para quatro ângulos de simetria facial/inclinação da cabeça na comparação GMDTM e GM (ES>0,54) e para dois ângulos entre o GM e o GC (ES>0,48). Conclusão: Os resultados do presente trabalho demonstraram a presença de alterações de postura corporal em mulheres com migrânea com e sem DTM em relação ao grupo controle, e as alterações de postura foram similares entre os GM e GMDTM na análise de relevância clínica. .

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...

Trastornos temporomandibulares en pacientes con maloclusiones / Temporomandibular disorders found in patients with malocclusions

Existe una prevalencia de trastornos oclusales en gran medida relacionados con la presencia de disfunción temporomandibular. Objetivo: determinar el grado de disfunción temporomandibular según el Índice de Maglione en correspondencia con la prevalencia de maloclusiones en el área de salud del policlínico "Turcios Lima". Métodos: se realizó un estudio observacional descriptivo, de corte transversal, en la consulta de ortodoncia, de junio del 2008 a junio del 2009. De un universo constituido por los 280 pacientes que acudieron al servicio de ortodoncia en el período señalado con presencia de maloclusiones, se seleccionó una muestra de 84 pacientes por muestreo aleatorio simple, teniendo en cuenta los criterios de inclusión y exclusión realizados por criterios de expertos. Resultados: presentaban disfunción temporomandibular 74 pacientes y dentro de ellos 44 (52,4 por ciento) tenían disfunción grado II (Moderada). El 97 por ciento de los pacientes con relación molar de clase II, presentaban disfunción temporomandibular. El 42,9 por ciento de los pacientes con una maloclusión, presentaban disfunción grado I. El 60 por ciento de los pacientes con dos maloclusiones presentaban disfunción grado II y el 66,7 por ciento de los pacientes con tres maloclusiones, presentaban disfunción grado III. La mayor cantidad de pacientes tuvieron disfunción grado II (Moderada). Conclusiones: el mayor por ciento de los pacientes con disfunciones presentó una clase II molar y a medida que aumentó el número de maloclusiones aumentó también la severidad de la disfunción(AU)
