Painful Temporomandibular Disorder Is Associated With Migraine in Adolescents: A Case-Control Study.

Some types of primary headaches and temporomandibular disorders (TMD) are comorbid in adults and highly prevalent in adolescents. Herein, we investigated the association of painful TMD with specific headache diagnoses (migraine, tension-type headache) and with headache frequency in adolescents. We also explored the association of headache diagnosis with the number of painful sites in the trigeminal area. Painful TMD was assessed using the Research Diagnostic Criteria for TMD. We conducted a case-control study of adolescents from 13 to 15 years old who were recruited among participants in a previous epidemiologic study conducted in Araraquara, SP, Brazil. Headaches were classified according to the second edition of the International Classification for Headache Disorders. Logistic, multinomial logistic and linear regression models were used to test associations. Of 149 individuals, 55.7% presented painful TMD. Adolescents with painful TMD (cases) were more likely to have migraine compared with those without TMD (controls; odds ratio = 3.0, 95% confidence interval = 1.47-6.19, P = .033). Significant differences were not observed for probable tension-type headache (P = .307) or tension-type headache (P = .834). Painful TMD was also associated with an increase in headache frequency (linear-by-linear association = 8.051; P = .005). Only migraine was associated with a greater number of painful sites on palpation in the trigeminal area (P = .001). Migraine and frequency of headache were associated with painful TMD in adolescents. PERSPECTIVE: Migraine and headache frequency were strongly associated with painful TMD in adolescents, and causality must be determined. For now, the presence of 1 condition should raise suspicion of the other and warrants collaboration between orofacial pain specialists and neurologists.

Effects of localized versus widespread TMD pain on sleep parameters in patients with bruxism: A single-night polysomnographic study.

OBJECTIVE: The purpose of this study was to investigate whether the presence of concomitant widespread pain could influence the polysomnographic characteristics of patients with Sleep Bruxism(SB) and chronic masticatory muscle pain(TMD). METHODS: 20 SB/TMD patients (17 women and 3 men) were evaluated according to the RDC/TMD questionnaire; and were divided into two groups according to the absence (Group A) or presence (Group B) of widespread pain. They were evaluated in a one night polysomnography paradigm. RESULTS: Group B had lower sleep efficiency (p=0.034) and higher mean age (p=0.000) than Group A. Self-reported orofacial pain complaints, clinical and emotional aspects (RDC/TMD Axis I and II), and SB PSG parameters were similar in both groups; all patients had masticatory myofascial pain and the pain characteristics were bilateral location (95.0%) and tightness/pressure quality (70.0%). CONCLUSIONS: At a single-night PSG, SB/TMD patients with widespread pain presented lower PSG sleep efficiency and higher mean age.

Parafunctional habits are associated cumulatively to painful temporomandibular disorders in adolescents.

This cross-sectional study was designed to evaluate the effect of sleep bruxism, awake bruxism and parafunctional habits, both separately and cumulatively, on the likelihood of adolescents to present painful TMD. The study was conducted on a sample of 1,094 adolescents (aged 12-14). The presence of painful TMD was assessed using the Research Diagnostic Criteria for Temporomandibular Disorders, Axis I. Data on sleep bruxism, awake bruxism and parafunctional habits (nail/pen/pencil/lip/cheek biting, resting one's head on one's hand, and gum chewing) were researched by self-report. After adjusting for potential demographic confounders using logistic regression, each of the predictor variables (sleep bruxism, awake bruxism and parafunctional habits) was significantly associated with painful TMD. In addition, the odds for painful TMD were higher in the concomitant presence of two (OR=4.6, [95%CI=2.06, 10.37]) or three predictor (OR=13.7, [95%CI=5.72, 32.96]) variables. These findings indicate that the presence of concomitant muscle activities during sleep and awake bruxism and parafunctional habits increases the likelihood almost linearly of adolescents to present painful TMD.

Temporomandibular Disorders in a Young Adolescent Brazilian Population: Epidemiologic Characterization and Associated Factors.

AIMS: To carry out an epidemiologic characterization of the most common subtypes of temporomandibular disorders (TMD) and to identify associated factors in a Brazilian sample of young adolescents. METHODS: From a population of public schoolchildren (12 to 14 years of age), 3,117 students were randomly invited to participate in this study. TMD was assessed according to the Research Diagnostic Criteria for TMD (RDC/TMD) Axis I, in addition to some questions of the Axis II history questionnaire. The associated factors, ie, difficulty with concentration/attention, anger, sadness, anxiety, headache complaints, oral parafunctions, diurnal jaw clenching, tooth grinding at night, and parents not living together, were assessed based on the responses of the adolescents and their parents to structured questions. For the statistical analyses, descriptive statistics, chi-square tests, odds ratio, and logistic regression models were used, adopting a 95% confidence interval and 5% level of significance. RESULTS: The sample consisted of 1,307 individuals (response rate of 41.9%), 56.8% (n = 742) girls. Overall, 397 (30.4%) adolescents presented with TMD, of whom 330 (25.2%) had painful TMD diagnoses. The majority of these had painful TMD of muscular origin (13.1%) and comprised chronic cases (14.9%). Girls presented higher frequencies of TMD overall, painful TMD, painful combined TMD, and chronic painful TMD diagnoses The final multivariate logistic regression model revealed that headache complaints (odds ratio 2.87; confidence intervals 2.21-3.72), oral parafunctions (2.08; 1.26-3.44), tooth grinding at night (2.05; 1.56-2.70), diurnal jaw clenching (1.96; 1.50-2.55), and parents not living together (1.38; 1.07-1.80) were the factors significantly associated with a TMD (overall) diagnosis. CONCLUSION: About 25% of the adolescents evaluated presented painful TMD, and the majority of these comprised muscular and chronic cases. Some factors, such as reports of headache complaints, oral parafunctions, tooth grinding at night, and parents not living together, were associated with this condition among young Brazilian adolescents. Special attention should be given to these factors among adolescents with TMD.

Temporomandibular disorders among Brazilian adolescents: reliability and validity of a screening questionnaire.

UNLABELLED: Temporomandibular disorders (TMD) screeners assume significant item overlap with the screening questionnaire proposed by the American Academy of Orofacial Pain (AAOP). OBJECTIVE: To test the reliability and validity of the Portuguese version of AAOP questions for TMD screening among adolescents. MATERIAL AND METHODS: Diagnoses from Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I were used as reference standard. Reliability was evaluated by internal consistency (KR-20) and inter-item correlation. Validity was tested by sensitivity, specificity, predictive values, accuracy and receiver operating characteristic (ROC) curves, the relationship between the true-positive rate (sensitivity) and the false-positive rate (specificity). Test-retest reliability of AAOP questions and intra-examiner reproducibility of RDC/TMD Axis I were tested with kappa statistics. RESULTS: The sample consisted of 1307 Brazilian adolescents (56.8% girls; n=742), with mean age of 12.72 years (12.69 F/12.75 M). According to RDC/TMD, 397 [30.4% (32.7% F/27.3% M)] of adolescents presented TMD, of which 330 [25.2% (27.6% F/22.2% M)] were painful TMD. Because of low consistency, items #8 and #10 of the AAOP questionnaire were excluded. Remaining items (of the long questionnaire version) showed good consistency and validity for three positive responses or more. After logistic regression, items #4, #6, #7 and #9 also showed satisfactory consistency and validity for two or more positive responses (short questionnaire version). Both versions demonstrated excellent specificity (about 90%), but higher sensitivity for detecting painful TMD (78.2%). Better reproducibility was obtained for the short version (k=0.840). CONCLUSIONS: The Portuguese version of AAOP questions showed both good reliability and validity for the screening of TMD among adolescents, especially painful TMD, according to RDC/TMD.

Association between painful temporomandibular disorders, sleep bruxism and tinnitus.

The present cross-sectional study was designed to investigate the association between sleep bruxism (SB), tinnitus and temporomandibular disorders (TMD). The sample consisted of 261 women (mean age of 37.0 years). The Research Diagnostic Criteria for Temporomandibular Disorders were used to classify TMD and self-reported tinnitus. SB was diagnosed by clinical criteria proposed by the American Academy of Sleep Medicine. The results showed an association between painful TMD and tinnitus (OR=7.3; 95%CI=3.50-15.39; p<0.001). With regard to SB, the association was of lower magnitude (OR=1.9; 95%CI=1.16-3.26; p<0.0163). When the sample was stratified by the presence of SB and painful TMD, only SB showed no association with tinnitus. The presence of painful TMD without SB was significantly associated with tinnitus (OR=6.7; 95%CI=2.64-17.22; p<0.0001). The concomitant presence of painful TMD and SB was associated with a higher degree of tinnitus severity (OR=7.0; 95%CI=3.00-15.89; p<0.0001). It may be concluded that there is an association between SB, painful TMD and self-reported tinnitus; however, no relationship of a causal nature could be established.

Relationship between levels of neuropeptide Substance P in periodontal disease and chronic pain: a literature review.

The aim of the current review was to investigate the relationship between levels of neuropeptide Substance P in periodontal disease and chronic pain. Substance P is a neuropeptide that is directly related with pain. In periodontal disease, it is expressed during the inflammatory process, and is one of the factors responsible for bone resorption. Studies have shown that Substance P levels are highest in the gingival crevicular fluid from sites with active periodontal disease and bone loss. The persistence of these substances could be sufficient to stimulate neurogenic inflammation in susceptible tissues, and cause pain. The scientific literature shows that Substance P expressed during periodontal disease can be a risk factor for patients with systemic inflammatory pathologies, such as chronic arthritis or rheumatoid arthritis. Additional research is needed to confirm the participation of this substance in the origin of some types of chronic pain.

Painful temporomandibular disorders, self reported tinnitus, and depression are highly associated.

OBJECTIVE: The aim of this study was to investigate the association among painful temporomandibular disorders (TMD), self reported tinnitus, and levels of depression. METHOD: The sample consisted of 224 individuals with ages ranges from 18 to 76 years. The Research Diagnostic Criteria for Temporomandibular Disorders Axis I were used to classify TMD and Axis II were used for self reported tinnitus, and to score the levels of depression. The odds ratio (OR) with 95% confidence interval (CI) was applied. RESULTS: The presence of painful TMD without tinnitus was significantly associated with moderate/severe levels of depression (OR=9.3, 95%; CI: 3.44-25.11). The concomitant presence of painful TMD and tinnitus self-report increased the magnitude of the association with moderate/severe levels of depression (OR=16.3, 95%; CI, 6.58-40.51). CONCLUSION: Painful temporomandibular disorders, high levels of depression, and self reported tinnitus are deeply associated. However, this association does not imply a causal relationship.

Entretanto, o desenho do estudo não permite estabelecer uma relação causal entre essas três entidades. .

Influência de abordagens biopsicossociais e autocuidados no controle das disfunções temporomandibulares crônicas / Influence of biopsychosocial approaches and self-care to control chronic pain and temporomandibular disorders

BACKGROUND AND OBJECTIVES: Temporomandibular joint disorder (TMD), which is a musculoskeletal condition of the masticatory system, may become chronic and further worsen quality of life (QL) of patients. Due to the interrelation between physical and emotional symptoms, there is increasing search for the integrative model, which includes psychosocial approaches for the treatment of painful conditions. This study aimed at reviewing in the literature the impact of education and simple self-care modalities on pain and disorders related to chronic painful TMD. CONTENTS: Psychosocial factors are often involved with pain chronicity, making bio-behavioral approaches increasingly more indicated to change pain perception and to decrease distress and psychosocial changes which go along with persistent pain. CONCLUSION: Current literature, although not extensive, indicates positive results of education and self-care methods for chronic painful TMD. Further studies are needed to reinforce such findings and spread the application of such approaches to control chronic and TMD pain.

JUSTIFICATIVA E OBJETIVOS: A disfunção temporomandibular (DTM), condição musculoesquelética do sistema mastigatório, pode se tornar crônica, causando maior comprometimento na qualidade de vida (QV) dos pacientes. Devido à inter-relação entre sintomas físicos e emocionais, há uma crescente busca pelo modelo integrativo, o qual inclui abordagens psicossociais para o tratamento de condições dolorosas. O objetivo deste estudo foi realizar uma revisão de literatura sobre o impacto da educação e modalidades simples de autocuidados podem ter na dor e na disfunção relacionadas à DTM dolorosa crônica. CONTEÚDO: Os fatores psicossociais estão frequentemente envolvidos na cronificação da dor, tornando as abordagens biocomportamentais cada vez mais indicadas para mudar a percepção da dor, reduzir o sofrimento e as alterações psicossociais que acompanham as dores persistentes. CONCLUSÃO: A literatura existente, apesar de não ser vasta, indica resultados positivos da aplicação de métodos de educação e autocuidados em DTM dolorosa crônica. Mais estudos são necessários para reforçar tais achados e disseminar a aplicação de tais abordagens no controle da dor crônica e da DTM.

Temporomandibular disorders, sleep bruxism, and primary headaches are mutually associated.

AIMS: To investigate the association among temporomandibular disorders (TMD), sleep bruxism, and primary headaches, assessing the risk of occurrence of primary headaches in patients with or without painful TMD and sleep bruxism. METHODS: The sample consisted of 301 individuals (253 women and 48 men) with ages varying from 18 to 76 years old (average age of 37.5 years). The Research Diagnostic Criteria for Temporomandibular Disorders were used to classify TMD. Sleep bruxism was diagnosed by clinical criteria proposed by the American Academy of Sleep Medicine, and primary headaches were diagnosed according to the International Classification of Headache Disorders-II. Data were analyzed by chi-square and odds ratio tests with a 95% confidence interval, and the significance level adopted was .05. RESULTS: An association was found among painful TMD, migraine, and tension-type headache (P < .01). The magnitude of association was higher for chronic migraine (odds ratio = 95.9; 95% confidence intervals = 12.51-734.64), followed by episodic migraine (7.0; 3.45-14.22) and episodic tension-type headache (3.7; 1.59-8.75). With regard to sleep bruxism, the association was significant only for chronic migraine (3.8; 1.83-7.84). When the sample was stratified by the presence of sleep bruxism and painful TMD, only the presence of sleep bruxism did not increase the risk for any type of headache. The presence of painful TMD without sleep bruxism significantly increased the risk in particular for chronic migraine (30.1; 3.58-252.81), followed by episodic migraine (3.7; 1.46-9.16). The association between painful TMD and sleep bruxism significantly increased the risk for chronic migraine (87.1; 10.79-702.18), followed by episodic migraine (6.7; 2.79-15.98) and episodic tension-type headache (3.8; 1.38-10.69). CONCLUSION: The association of sleep bruxism and painful TMD greatly increased the risk for episodic migraine, episodic tension-type headache, and especially for chronic migraine.

Medical conditions and body pain in patients presenting orofacial pain.

OBJECTIVE: To verify the frequency of self-reported medical conditions and pain areas in orofacial pain patients, comparing them with patients from the routine dental care. METHODS: Data were collected from archives of the Orofacial Pain Clinic (Group A, n=319) and of the routine dental care clinics (Group B, n=84) at Faculdade de Odontologia de Araraquara, São Paulo, in Brazil. All individuals answered a standardized clinical questionnaire and completed a body map indicating their pain areas. RESULTS: The Mann-Whitney's test demonstrated that Group A presented a higher mean number of medical reports than Group B (p=0.004). In both groups, Pearson's correlation test showed that the highest frequencies of medical conditions were positively correlated to highest frequencies of painful areas (0.478, p=0.001 and 0.246, p=0.000, respectively). CONCLUSIONS: Group A tended to report more medical conditions and there was a positive correlation between the number of medical conditions and the one of pain areas for both groups.

New approaches to dental occlusion: a literature update.

Because the study of occlusion is a basic area in dentistry, its components, physiology and integration with the stomatognathic system (SS) have been the subject of interest in the scientific literature. However, the focus given to this issue has changed substantially. Currently, new approaches have been proposed in order to update concepts and to demonstrate the full integration and functionality of this system within the human body. With this approach, the authors proposed the following literature review aimed at gathering recent papers (published from 2000 to 2010) with innovative study design, methodology and/or results. The authors' intention is to show the main trends in the study of occlusion and the SS. The literature review was conducted in the PubMed database, using initially the term "dental occlusion" as a key-word. As items of interest were found, papers were grouped by categories according to their main subject matter. Forty-seven articles were selected and the main categories obtained were: 1. functional magnetic resonance imaging (fMRI); 2. brain activation; 3. masticatory/occlusal function; 4. body function and physical performance; 5. osseoperception; 6. finite element models; and 7. occlusion and pain. Observing the current literature, the authors found that recent studies present different methodologies for the study of occlusion. These studies have allowed scientists to obtain detailed information about the physiology of occlusion and the SS, as well as about its integration in the body. Research in this area should be continued in order to clarify, in detail, the role of each component of the SS and its interaction with human physiology.

OBJETIVO: Verificar a frequência de problemas médicos autorrelatados e a frequência de áreas de dor no corpo em pacientes com dor orofacial, comparando-os a pacientes submetidos a tratamento odontológico de rotina. MÉTODOS: Os dados foram coletados dos arquivos da Clínica de Dor Orofacial (Grupo A, n=319) e de clínicas de tratamento odontológico rotineiro (Grupo B, n=84) da Faculdade de Odontologia de Araraquara, São Paulo, Brasil. Os indivíduos responderam a questionários e preencheram um mapa corporal indicando os locais de dor. RESULTADOS: O teste de Mann-Whitney demonstrou que o Grupo A apresentou uma média de relatos de problemas médicos superior ao Grupo B (p=0,004). Para ambos os grupos, o teste de correlação de Pearson demonstrou correlação positiva entre os problemas médicos e a frequência de áreas dolorosas (respectivamente, 0,478, p=0,001 e 0,246, p=0,000). CONCLUSÕES: O Grupo A relatou maior número de problemas médicos e houve correlação positiva entre a frequência desses problemas e a de áreas de dor para ambos os grupos.

Mapas de dor corporal aprimoram os relatos das queixas dolorosas em pacientes com dor orofacial / Body pain maps improve the report of painful complaints in patients with orofacial pain

JUSTIFICATIVA E OBJETIVOS: Identificar as queixas dolorosas dos pacientes é essencial para determinar diagnósticos e intervenções terapêuticas adequadas em dor orofacial (DOF). Assim, o objetivo deste estudo foi verificar a frequência das queixas de dor relatadas comparando-as àquelas marcadas pelos pacientes em mapas de dor. MÉTODO: Os dados foram coletados dos prontuários de 532 pacientes da Clínica de Dor Orofacial da Faculdade de Odontologia de Araraquara. Os indivíduos responderam a um questionário informando suas queixas de dor e completaram um mapa corporal indicando as áreas dolorosas. A frequência dos relatos foi comparada à frequência dos locais identificados nos mapas. Foram consideradas nove regiões anatômicas: cabeça, face, pescoço, ombros, braços, tórax, abdômen, costas e pernas. Também foram calculados sensibilidade, especificidade e valores kappa comparando os relatos de dor aos mapas, os últimos considerados padrão-ouro. RESULTADOS: A média etária da amostra foi de 33,5 ± 13,8 anos, 33,9 ± 13,9 anos para as mulheres e 31,7 ± 13,1 anos para os homens. Foi observada maior prevalência de dor entre as mulheres. Em ambos os gêneros, as regiões com mais queixas de dor estavam localizadas na parte superior do corpo e uma diferença significativa entre os relatos de dor e os desenhos de dor foi observada para as regiões abaixo do pescoço. Os mapas de dor corporal demonstraram superioridade sobre os relatos de dor na identificação das queixas dolorosas durante a anamnese. CONCLUSÃO: O relato da queixa principal não foi um método eficiente para conhecer todas as queixas dolorosas, pois os mapas corporais evidenciaram a presença de dores adicionais em pacientes com DOF.

BACKGROUND AND OBJECTIVES: Assessing patients´ pain complaints is essential for determining adequate diagnosis and therapeutic interventions in orofacial pain (OFP). Thus, the aim of this study was to verify the frequency of reported pain complaints compared to those marked on patients´ body pain maps. METHOD: Data was collected from the Orofacial Pain Clinic archives (532 patients) of Araraquara Dental School. All individuals answered a standardized clinical questionnaire to report their chief complaints and completed a body map indicating their pain areas. The frequency of reported pain complaints was compared to the frequency of painful sites identified on body maps. Nine anatomic regions were considered: head, face, neck, shoulders, arms, chest, abdomen, back, and legs. In addition, sensitivity, specificity and kappa values were calculated comparing the pain reports to body pain drawings, the latter being considered as gold standard. RESULTS: The mean age of total sample was 33.5 ± 13.8 years, 33.9 ± 13.9 years for women and 31.7 ± 13.1 years for men. Higher prevalence of pain was observed among female patients. Overall, the regions of greater pain reports were located in the upper body areas, both for women and men. A significant difference between the pain reports and the pain drawings was observed for the body regions below the neck, in both genders. The body pain maps demonstrated superiority against pain reports in assessing patients´ painful complaints during the anamnesis. CONCLUSION: Pain reports were not an efficient method for diagnosing all patient´s painful complaints, because body pain maps evidentiated additional pain complaints in OFP patients.

Clinical features of the sleep bruxism and gastroesophageal reflux association deserve professional attention / Características clínicas da associação entre o bruxismo do sono e o refluxo gastroesofágico merecem atenção profissional

Introdução: Bruxismo tem sido definido como uma atividade parafuncional oral que consiste em apertar e/ou ranger os dentes durante o sono ou na vigília. Além do bruxismo do sono (BS), outros movimentos orofaciais também podem, esporadicamente, ocorrer durante o sono. A regurgitação ocasional e a queimação no peito devido ao refluxo gastroesofágico (RGE) são freqüentes sintomas relatados pela população em geral. A RGE refere-se à presença de sinais e sintomas secundários, com ou sem sinais de lesões na mucosa do esôfago. Os dentistas são, muitas vezes, os profissionais da saúde que primeiro diagnosticam o RGE por meio da observação de suas manifestações orais. Objetivo: Assim, o objetivo do presente artigo foi discutir os procedimentos clínicos e diagnósticos em dois pacientes com BS e RGE, contribuindo assim para a difusão do conhecimento sobre a interação dessas duas entidades. Recomenda-se aos dentistas estarem atentos para identificar os primeiros sinais de RGE que se manifestam na cavidade oral. Conclusão: Neste ponto, destaca-se a importância de tratar o paciente como um todo, esforçando-se para identificar outras fontes de problema que poderiam atuar como fatores agravantes destas condições.

Introduction: Bruxism has been defined as an oral parafunctional activity that includes clenching and/or grinding the teeth while asleep or awake. In addition to sleep bruxism (SB), various other orofacial movements sporadically occur during sleep. Occasional regurgitation and heartburn due to gastroesophageal reflux (GER) are frequent in the general population. GER refers to the presence of symptoms that are secondary to the reflux of gastric content through the esophagus with or without signs of esophageal mucosal lesions. Dentists are often the first health care professionals to diagnose GER through observation of its oral manifestation. Objective: The aim of the present case reports was to discuss the diagnosis and clinical procedures followed in two patients with SB and GER, thereby contributing to the dissemination of knowledge about these two entities. We therefore recommend dentists to be alert to identifying the first signs of GER that appear in the oral cavity. Conclusion: At this point, we highlight the importance of treating the patient as a whole, in an endeavor to identify other sources of the problems that could contribute as factors aggravating these conditions.

Sensibilidade dolorosa à palpação em pacientes com disfunção temporomandibular crônica / Sensibilidad dolorosa a la palpación en pacientes con disfunción temporomandibular crónica / Painful sensitivity to palpation in patients presenting with chronic temporomandibular dysfunction

Cefaléias primárias estão freqüentemente relacionadas à disfunção temporomandibular, sendo o aumento da sensibilidade dolorosa um achado comum nesses pacientes. Este estudo propôs investigar a sensibilidade dolorosa à palpação em pacientes com disfunção temporomandibular crônica, comparando grupos com presença ou ausência de cefaléias primárias. A disfunção temporomandibular e o tipo de cefaléia primária foram diagnosticados, respectivamente por meio dos critérios de diagnóstico para pesquisa das desordens temporomandibulares e por um questionário baseado na Classificação Internacional de Cefaléias (2004). A localização, avaliação e o agrupamento dos sítios musculares e articulares para palpação foram realizados segundo os critérios de diagnóstico para pesquisa das desordens temporomandibulares, considerando-se o temporal, masseter, articulação temporomandibular e sítios cervicais bilateralmente. A amostra foi composta por 213 (88,0 por cento) mulheres e 29 (12,0 por cento) homens, com faixa etária média de 37,41 anos. As médias do número de sítios positivos à palpação nos grupos sem cefaléia, cefaléia do tipo tensional, migrânea e cefaléia crônica diária e foram respectivamente: 12,43; 14,38; 15,21 e 15,62 (p= 0,107) (mínima 2 e máxima 22). Apenas para os sítios do músculo temporal foi detectada diferença estatisticamente significante entre os grupos de cefaléia quanto à sensibilidade dolorosa à palpação (p= 0,007). O número de sítios dolorosos não foi estatisticamente diferente entre os grupos estudados e apenas o músculo temporal demonstrou diferença estatisticamente significante quanto ao grau de dor à palpação(AU)

The cephalalgias are frequently associated with the temporomandibular disorders being common to find an increase of pain sensitivity in these patients. Thus, the objective of present study was to assess the sensitivity to palpation in patients presenting with chronic temporomandibular disorders comparing two groups one with headache and other without it, respectively. The temporomandibular disorders and the primary cephalalgias were diagnosed according the Diagnostic Criteria for the Research of Temporomandibular Disorders and by a questionnaire based on the International Classification of the Cephalalgias (2004). Location, assessment and grouping of muscular and articular areas for palpation were carried out according to the Diagnostic Criteria for above mentioned disorders, considering bilaterally the masseter muscle, the temporalis muscle, the cervical region and the temporomandibular joint. Sample included 213 (88.0 percent) of women and 29 (12.0 percent) men with a mean age of 37.41 years. The mean of number of zones positive to palpation in the groups without headaches, tension headache, migraine and daily chronic headache were: 12.43, 14.38, 15.21 and 15.62 (p= 0.107) (min 2 max 22). The areas of temporalis muscle showed significant differences among groups (p= 0.007). The number of painful points was not statistically different among groups and only in the temporalis muscle there were differences with statistical significant to palpation(AU)

Las cefaleas están frecuentemente relacionadas con los trastornos temporomandibulares, por esta razón es común encontrar un aumento de sensibilidad al dolor en los pacientes que padecen dicha enfermedad. El objetivo de este estudio fue evaluar la sensibilidad a la palpación en pacientes con trastornos temporomandibulares crónicos. Se realizó una comparación entre 2 grupos con cefalea y sin cefalea respectivamente. Los trastornos temporomandibulares y las cefaleas primarias, fueron diagnosticados mediante los criterios diagnósticos para la investigación de los trastornos temporomandibulares y por un cuestionario basado en la clasificación internacional de cefaleas en el año 2004. La localización, evaluación y agrupación de las áreas musculares y articulares para la palpación, se realizaron de acuerdo a los criterios diagnósticos para la investigación de los trastornos temporomandibulares, se tuvo en cuenta el músculo masetero, el temporal, la región cervical y la articulación temporomandibular bilateralmente. La muestra fue de 213 mujeres (88,0 por ciento) y 29 hombres (12,0 por ciento), con una media de edad de 37,41 años. La media del número de zonas positivas a la palpación en los grupos sin cefalea, dolor de cabeza de tipo tensional, migraña y cefalea crónica diaria fueron: 12,43; 14,38; 15,21; 15,62 y (p= 0,107) (mínimas 2 y máximas 22). Las áreas del músculo temporal demostraron diferencias significativas entre los grupos (p= 0,007). El número de puntos dolorosos no fue estadísticamente diferente entre los grupos y solo en el músculo temporal se observó diferencias estadísticamente significativas a la palpación(AU)

Fisioterapia no tratamento da dor orofacial de pacientes com disfunção temporomandibular crônica / Physiotherapy as treatment of orofacial pain in patients with chronic temporomandibular dysfunction

Estudos recentes têm demonstrado resultados consistentes com o uso das terapias físicas nos casos de dor e limitação de movimentos em Disfunção Temporomandibular (DTM). Dessa forma, nosso objetivo foi avaliar o efeito de dez sessões de fisioterapia, exercícios e laserterapia no tratamento da dor muscular e da artralgia em uma mulher com DTM. O alívio médio dos sintomas dolorosos obtidos por sessão foi de 20 por cento, atingindo valor zero nas últimas semanas e mantendo-se estável por 60 dias após o término do tratamento. Os resultados demonstraram que o protocolo de tratamento utilizado foi efetivo no alívio da dor da região articular, assim como da tensão do músculo masseter, levando a paciente a reduzir a ingestão de medicamentos para controle da dor. Entretanto, estudos adicionais são necessários para se definir com maior precisão o efeito de outros programas de fisioterapia, assim como sua interação com as demais modalidades de tratamento(AU)

Estudios recientes han demostrado resultados consistentes con el uso de la terapia física en casos de dolor y limitación del movimiento por disfunción temporomandibular. Esta investigación tuvo como objetivo evaluar el efecto de 10 sesiones de terapia física, ejercicio y terapia por láser en el tratamiento del dolor muscular y artralgias en una mujer con disfunción temporomandibular. El alivio de los síntomas dolorosos obtenido por sesión fue sobre un 20 por ciento al acercarse a 0 en las últimas semanas y se mantuvo estable después de 60 días de finalizar el tratamiento. Los resultados mostraron que el protocolo de tratamiento utilizado fue eficaz para reducir el dolor de la articulación temporomandibular y la tensión del músculo masetero, a su vez le permitió al paciente reducir el uso de medicamentos. Sin embargo, son necesarios más estudios para definir con mayor precisión el efecto de otros programas de fisioterapia y su interacción con otras modalidades de tratamiento(AU)

Recent studies have shown consistent results using the physical therapy in cases of pain and limitation of movement from temporomandibular dysfunction. Thus, our objective was to assess the effect of ten sessions of physical therapy and laser therapy in treatment of muscular pain and arthralgias in a woman with temporomandibular dysfunction. The painful symptoms relief achieved by session was over 20 percent, up to zero at the end of treatment. Results demonstrated that the treatment protocol used was effective to reduce the temporomandibular joint and the masseter muscle tension and a decreased of drugs by patient. However, more studies are needed to define with more accuracy the effect of other physiotherapy programs and its interaction with other treatment modalities(AU)
