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).

Temporomandibular Disorders are Associated with Sociodemographic Factors, Health-Related and Oral Conditions in Adolescents: A Cross-Sectional Study

Abstract Objective: To assess the association between temporomandibular disorder (TMD) with sociodemographic factors, health-related factors, and oral conditions in adolescents. Material and Methods: This cross-sectional study was developed with 89 adolescents between 13 to 18 years. TMD diagnosis was obtained by the Research Diagnostic Criteria for Temporomandibular Disease (RDC/TMD) Axis I. Diagnoses of chronic pain, depression, presence of non-specific physical symptoms, including pain and anxiety, were obtained by the RDC/TMD Axis II. The feeling of happiness was measured by the Subjective Happiness Scale. Socio-economic and demographic characteristics were collected through self-administered questionnaires. Patients were examined for dental caries, dental trauma, malocclusion, and tooth wear. Parents answered a sociodemographic, economic, and general health questionnaire. Data were submitted to descriptive statistics, and a logistic regression model was used to assess the association between TMD and the socio-economic, demographic, health-related, and clinical variables. Results: TMD prevalence was 42%. TMD was associated to skin color (p=0.040), use of medications in the past year (p = 0.020) and previous dental trauma (p=0.030). Also, it tended to be associated with the presence of probable awake bruxism (p=0.053). Conclusion: Sociodemographic factors, health-related factors, and oral conditions play a role in TMD, with nonwhite adolescents, those who had used medications in the past year and/or had previous dental trauma having a greater chance of present this disorder (AU).

Temporomandibular joint dysfunction syndrome and police work stress: an integrative review. / Síndrome da disfunção da articulação temporomandibular e o estresse presente no trabalho policial: revisão integrativa.

This study aimed to investigate whether stress found in activities performed by Brazilian police workers is associated with the risk of developing a temporomandibular joint dysfunction syndrome (TMD), a disorder that is commonly associated with stressful conditions. An integrative literature review on stress, TMD and police work was carried out. We identified several stressors in the work of Brazilian police officers and observed that stress influences the development, aggravation and treatment of TMD symptoms. The quality of life and health of TMD carriers is compromised. The fact that studies have shown the association between stress and activities carried out by Brazilian police officers, as well as between stress and TMD, has led to the assumption of a possible relationship between stress caused by police work and the risk of these workers developing TMD. It is recommended that individuals be thoroughly examined before being treated and that such treatment be multidisciplinary. The literature on TMD in police workers is still incipient, which is why we recommend the development of further studies on the topic.

O estudo objetivou investigar se o estresse presente nas atividades dos trabalhadores da polícia brasileira pode ter relação com o desenvolvimento da síndrome da disfunção da articulação temporomandibular (DTM), uma doença comumente associada a condições estressantes. Realizou-se uma revisão integrativa de literatura sobre os temas estresse, DTM e atividade policial. Foram identificadas diversas fontes estressoras no trabalho do policial brasileiro e observou-se que o estresse influencia no desenvolvimento, agravamento e tratamento dos sintomas da síndrome. Há comprometimento na qualidade de vida e saúde dos portadores de DTM. O fato de estudos terem mostrado associação entre estresse e atividades desenvolvidas pelos policiais brasileiros, bem como relação entre estresse e DTM, levou à suposição de que é possível haver relação entre o estresse gerado pelo trabalho executado por policiais e o risco de desenvolvimento da DTM por essa classe de trabalhadores. É recomendado que o indivíduo portador da síndrome seja avaliado como um todo antes da execução do tratamento e que esse tratamento seja multidisciplinar. A literatura sobre DTM em policiais ainda é incipiente, motivo pelo qual sugere-se o desenvolvimento de estudos sobre o tema.

Prevalence of Temporomandibular Disorders in an Adult Brazilian Community Population Using the Research Diagnostic Criteria (Axes I and II) for Temporomandibular Disorders (The Maringá Study).

PURPOSE: The primary objective of this study was to assess the prevalence of temporomandibular disorders (TMDs) and comorbid factors (sleep bruxism and headaches). This study was a cross-sectional population survey in the city of Maringá, state of Paraná, Brazil. MATERIALS AND METHODS: Axes I and II of the Research Diagnostic Criteria for TMD (RDC/TMD) were used for assessment of TMD signs and symptoms. The population was users of the Brazilian public health system (SUS), of both sexes, between the ages of 20 and 65 years, and not seeking treatment for TMD. RESULTS: The selected population (N = 1,643) was composed mostly of (a) women (65.9%), (b) married or single individuals (90.6%), (c) Caucasians (70.1%), (d) individuals aged 32.7 ± 10.3 years, (e) individuals earning a medium income (75.1%), and (f) those who had completed a high school education or higher (79.9%). According to the chronic pain grade classification (CPG) in the RDC/TMD Axis II, 36.2% of the population had some degree of TMD pain (CPG I to IV); however, only 5.1% had severe limitation due to pain (CPG III or IV). In the RDC/TMD Axis I diagnoses, 29.5% presented with muscle disorders (group I), 7.9% with disk displacements (group II), and 39.1% with other joint disorders (group III). Headaches were present in 67.9% and awake and sleep bruxism in 30% and 33.4% of the population, respectively. CONCLUSION: The prevalence of signs and symptoms of TMD was high in this population, but with low disability; however, the proportion of patients in need of treatment was much lower.

Electromyography and asymmetry index of masticatory muscles in undergraduate students with temporomandibular disorders

Aim: To compare the electromyographic activity and the asymmetry index among degrees of severity of temporomandibular disorders (TMD). Methods: Surface electromyography (EMG) of the right and left masseter and temporalis muscles was performed in 126 undergraduate students at rest and at maximal voluntary contraction. Three measurements were performed for five seconds of maximal contraction and mandibular rest. The degree of temporomandibular dysfunction was identified according to the Fonseca anamnestic index. The analysis of the asymmetry index for two pairs of muscles during maximal voluntary contraction was based on the asymmetry index proposed by Naeije, McCarrol and Weijs (1989). Results: 48.41% of the sample had mild TMD, followed by volunteers without TMD (26.98%), moderate TMD (19.05%) and severe (5.56%). The survey results show absence of correlation between the Fonseca anamnestic index and electromyographic activity at rest and at maximal voluntary contraction in undergraduate students in both muscles (p>0.05) and the asymmetry index did not differ between the analyzed groups. Conclusions: For the population of undergraduate students, there is no evidence that the presence and severity of TMD influence the EMG activity of masseter and temporalis muscles and the muscle asymmetry index at rest and maximal voluntary contraction.

Marcadores tempranos de patologías de la articulación temporomandibular en pacientes con artritis reumatoidea / Early markers of temporomandibular joint pathology in patients with rheumatoid arthritis

Evaluar, en pacientes con artritis reumatoidea, los síntomas y signos clínicos de la ATM desde el punto de vista odontológico y reumatológico, interrelacionando los hallazgos realizados con reactantes de fase aguda -como eritrosedimentación- y con marcadores de la enfermedad -como el Health Assessment Questionaire (HAQ) y el Score Disease Activity. Determinar cuáles son los predictores más importantes de la enfermedad, a fin de facilitar el diagnóstico y el manejo temprano de patologías de la ATM en la artritis reumatoidea (DAS28). Materiales y métodos: se evaluaron 190 articulaciones de pacientes con artritis reumatoidea -considerando dos por paciente- y 22 controles. La evaluación de la ATM fue realizada mediante inspección clínica, cuestionarios y radiografías. La artritis reumatoidea fue testeada clínica, serológica y radiográficamente. Para evaluar las ATMs, se utilizó el score de Rohlin y Petersson y, para las manos, el de Larsen. Para la diferencia de porcentajes (p) se empleó la prueba de las diferencias proporcionales y la asociación se determinó con el coeficiente de correlación de Pearson (r). Resultados: se hallaron anormalidades radiográficas en 167 (87,89 por ciento) de las 190 ATM evaluadas. El 57,37 por ciento de los pacientes con artritis reumatoidea referían dolor en la ATM. El 58,95 por ciento presentaba menos de 20 piezas dentarias. El 70,53 por ciento tenía la apertura bucal máxima disminuida. Existió una asociación altamente significativa (A/S=0,000) entre las cefaleas de los pacientes con artritis reumatoidea y el grupo control; una asociación no significativa (N/S) entre los resultados del DAS28, el HAQ y la ERS (eritrosedimentación) con las erosiones de la ATM; y A/S=0,62 entre las erosiones de la mano y las de la ATM. Conclusión: se determinó que existe una alta prevalencia de problemas articulares en los pacientes con AR. Las erosiones en la mano se correlacionan con las de la ATM. Por todo esto, se sugiere la evaluación...

Temporomandibular disorders in a sample population of the Brazilian northeast.

Temporomandibular disorder (TMD) is a common condition. This study is part of a research group and it investigated the prevalence of TMD and myofascial pain and its association with gender, age and socioeconomic class. The sample comprised 100 subjects, aged 15 to 70, users of the Family Health Units' services, in the city of Recife, PE, Brazil. The TMD degree was evaluated using the Research Diagnostic Criteria for TMD and socioeconomic class by the Economic Classification Criteria Brazil. Categorical variables were analyzed by chi-square test for proportions and Fisher's exact test for 2x2 tables, and binary logistic analysis to track the relationship between the independent and dependent variables. According to the results, 42% of the subjects had TMD and 14% myofascial pain. No statistically significant association could be found between TMD and gender or socioeconomic class, but it was found to have statistically significant association with age, and myofascial pain was associated with socioeconomic class. Considering that the results of the present study should be confirmed by further studies and the fact that this was a pilot study, the prevalence must be analyzed with caution.

La disfunción temporomandibular y su relación con algunos factores de riesgo en niños de 7 a 11 años: Los Arabos, Matanzas / Temporomandibular dysfunction and its relationship with several risk factors in children aged 7 to 11 years: Los Arabos, Matanzas

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.

Association between prosthetic factors and temporomandibular disorders in complete denture wearers.

OBJECTIVE: The purpose of this study was to investigate the prevalence of temporomandibular disorders (TMD) in denture wearers and the association between prosthetic factors and this condition. BACKGROUND: There is no consensus about the relationship between prosthetic factors and TMD among denture wearers. MATERIALS AND METHODS: The sample was composed of 92 patients wearing both maxillary and mandibular complete dentures. The Research Diagnostic Criteria for TMD (RDC/TMD) were adopted for patient examination. Objective evaluation of denture quality was determined by analysis of retention and stability of mandibular denture, interocclusal distance, articulation and occlusion. Association between denture quality and TMD diagnosis was analysed using chi-square and Fisher's exact tests. RESULTS: 37.4% of the patients presented TMD. Denture quality was not significantly associated with the presence of TMD: mandibular retention (p = 0.466); mandibular stability (p = 0.466); interocclusal distance (p = 0.328); centric relation (p = 0.175); and balanced occlusion (p = 0.56). CONCLUSION: Within the scope of this case-controlled cross-sectional study, no robust association between prosthetic factors and TMD was found.

Correlation between self-reported and clinically based diagnoses of bruxism in temporomandibular disorders patients.

The present investigation was performed in a population of patients with temporomandibular disorders (TMD), and it was designed to assess the correlation between self-reported questionnaire-based bruxism diagnosis and a diagnosis based on history taking plus clinical examination. One-hundred-fifty-nine patients with TMD underwent an assessment including a questionnaire investigating five bruxism-related items (i.e. sleep grinding, sleep grinding referral by bed partner, sleep clenching, awake clenching, awake grinding) and an interview (i.e. oral history taking with specific focus on bruxism habits) plus a clinical examination to evaluate bruxism signs and symptoms. The correlation between findings of the questionnaire, viz., patients' report, and findings of the interview/oral history taking plus clinical examination, viz., clinicians' diagnosis, was assessed by means of φ coefficient. The highest correlations were achieved for the sleep grinding referral item (φ = 0·932) and for the awake clenching item (φ = 0·811), whilst lower correlation values were found for the other items (φ values ranging from 0·363 to 0·641). The percentage of disagreement between the two diagnostic approaches ranged between 1·8% and 18·2%. Within the limits of the present investigation, it can be suggested that a strong positive correlation between a self-reported and a clinically based approach to bruxism diagnosis can be achieved as for awake clenching, whilst lower levels of correlation were detected for sleep-time activities.

Conclusiones: existió una alta frecuencia de disfunciones temporomandibulares en la población estudiada(AU)

Objective: To identify temporomandibular dysfunction frequency in 16 to 18 years-old students from Roberto Labrada Ávila high school and to describe signs and symptoms of temporomandibular dysfunction and their relationship to the gender among these adolescents. Method: a cross-sectional, observational and descriptive study was carried out in 86 students ranging 16 to 18 years from Roberto Labrada Ávila high school during 2010. They were evaluated by using the Helkimo's clinical index to measure the frequency of temporomandibular dysfunctions. Demographic and social variables, signs and symptoms detected during physical examination were all evaluated. The collected data were statistically analyzed. Results: In the study group, 69.8 percent showed some temporomandibular dysfunction; the most observed sign was the functional disturbance of temporomandibular joint in 66.3 percent of the students. The percentage of affected females was 67.5 percent whereas that of males was 64.7 percent. Conclusion: The frequency of temporomandibular dysfunctions was high in the study sample(AU)

Sleep bruxism increases the risk for painful temporomandibular disorder, depression and non-specific physical symptoms.

To explore the relationship between sleep bruxism (SB), painful temporomandibular disorders (TMD) and psychologic status in a cross-sectional study. The sample consisted of 272 individuals. The Research Diagnostic Criteria for TMD (RDC/TMD) was used to diagnose TMD; SB was diagnosed by clinical criteria proposed by The American Academy of Sleep Medicine. The sample was divided into four groups: (1) patients without painful TMD and without SB, (2) patients without painful TMD and with SB, (3) patients with painful TMD and without SB and (4) patients with painful TMD and with SB. Data were analysed by Odds Ratio test with a 95% confidence interval. Patients with SB had an increased risk for the occurrence of myofascial pain (OR = 5·93, 95% CI: 3·19-11·02) and arthralgia (2·34, 1·58-3·46). Group 3 had an increased risk for moderate/severe depression and non-specific physical symptoms (10·1, 3·67-27·79; 14·7, 5·39-39·92, respectively), and this risk increased in the presence of SB (25·0, 9·65-64·77; 35·8, 13·94-91·90, respectively). SB seems to be a risk factor for painful TMD, and this in turn is a risk factor for the occurrence of higher depression and non-specific physical symptoms levels, but a cause-effect relationship could not be established.
