Perceptions of pain levels and chewing impairment among adolescents undergoing orthodontic treatment with fixed appliances

Aim: the aim of this cohort study was to evaluate the perceptions of adolescents regarding pain levels and chewing impairment throughout the first 12 months of orthodontic treatment with fixed appliances. methods: a total of 120 adolescents aged 11 and 12 years undergoing orthodontic treatment at the faculty of dentistry of the Federal University of Minas Gerais participated in this study. malocclusion was evaluated by means of the dental aesthetic index. pain level and degree of chewing impairment were evaluated by means of two questions selected from the short form of the child perceptions questionnaire (CPQ11-14). each question had five response options with the following scoring system: never (0), once or twice (1), sometimes (2), often (3) and every day/almost every day (4). both questions were answered by the adolescents at four different times: before fixed appliances' placement (T1), one month after banding and fixed appliances' bonding (T2), four months after banding and fixed appliances' bonding (T3), and 12 months after banding and fixed appliances' bonding (T4). results: the mean age of adolescents was 11.39 (±0.68). significant differences were observed for pain levels (p=0.038) and chewing impairment (p=0.020) over the study period. pain levels at T1 were significantly lower than at T2 (p=0.038) and T4 (p=0.020). chewing impairment at T1 was significant lower than at T2 (p<0.001), T3 (p=0.014) and T4 (p=0.005). conclusion: adolescents undergoing orthodontic treatment with fixed appliances present an increase in pain levels and in chewing impairment.

Salivary stress biomarkers and anxiety symptoms in children with and without temporomandibular disorders

Abstract The etiology of temporomandibular disorders (TMD), which are considered as a heterogeneous group of psychophysiological disturbances, remains a controversial issue in clinical dentistry. This study aimed to evaluate whether the salivary alpha-amylase (sAA), cortisol levels, and anxiety symptoms differ between children with and without TMD. Initially, 316 young subjects were screened in public schools (nonreferred sample); 76 subjects aged 7-14 years were selected and comprised the TMD and control groups with 38 subjects each matched by sex, age, and the presence/absence of sleep bruxism. Four saliva samples were collected: upon waking, 30 min and 1 h after awakening (fasting), and at night (at 8 PM) on 2 alternate days to examine the diurnal profiles of cortisol and sAA. Anxiety symptoms were screened using the Multidimensional Anxiety Scale for Children (MASC-Brazilian version). Shapiro-Wilk test, Student's t-test/Mann-Whitney U test, and correlation tests were used for data analysis. No significant differences were observed in the salivary cortisol area under the curve (AUCG mean ± SD = 90.22 ± 63.36 × 94.21 ± 63.13 µg/dL/min) and sAA AUCG (mean ± SD = 2544.52 ± 2142.00 × 2054.03 ± 1046.89 U/mL/min) between the TMD and control groups, respectively (p > 0.05); however, the clinical groups differed in social anxiety domain (t = 3.759; CI = 2.609, 8.496), separation/panic (t = 2.243; CI = 0.309, 5.217), physical symptoms (U = 433.500), and MASC total score (t = −3.527; CI = −23.062, −6.412), with a power of the test >80% and large effect size (d = 0.80), with no significant correlation between the MASC total score, cortisol, and sAA levels. Although children with TMD scored higher in anxiety symptoms, no difference was observed in the salivary stress biomarkers between children with and without TMD.

Assessment of knowledge on temporomandibular disorders among Mexican dental educators / Evauación del conocimiento sobre trastornos temporomandibulares en docentes de odontología en México

Temporomandibular disorders (TMDs) is an umbrella term that embraces a group of musculoskeletal and neuromuscular conditions that involve the temporomandibular joints, muscles and all associated tissues. Because of the relatively high number of patients with TMDs in the population, instruction in this area of health care should be included on all dental curricula. Although levels of knowledge among dentists have been evaluated in several countries, they have not been in Mexico. This study evaluates the dental faculty's range of knowledge about TMD at five dental schools in Puebla, Mexico. Using an observational design, a survey was administered to 161 educators in order to assess their knowledge of TMD. Four domains were assessed, including: a) pathophysiology; b) psychophysiology; c) psychiatric disorders; and d) chronic pain. Overall knowledge of TMD was measured using a consensus of TMD experts' answers as a reference standard1The results show that educators' overall knowledge had 55% agreement with the reference standard. Individually, the psychophysiological domain was correctly recognized by 77.7% of the educators; correct responses on the other domains ranged from 38% to 56%. This study demonstrates the need to incorporate standardized TMDs instruction into the dental curricula at Mexican Universities, without which graduating dentists will lack the necessary knowledge or experience to diagnose and manage their TMD patients.

Los Trastornos Témporomandibulares (TTM) incluyen un grupo de condiciones musculoes que léticas y neuromusculares que afectan a la Articulación Temporomandibular (ATM), los músculos masticadores y otros tejidos asociados. Debido al número relativamente alto de pacientes con TTM en la población, la educación en esta área de la salud debe ser incluida en las currículas de las escuelas de odontología. A pesar de que el nivel de conocimiento sobre TTM ha sido evaluado en diversos países, esto no ha sido realizado en México, por lo que el objetivo del presente estudio fue evaluar el nivel de conocimiento sobre los TTM de los profesores de odontología en cinco universidades de Puebla, México. Bajo un diseño observacional, se administró una encuesta a 161 docentes de odontología para evaluar el nivel de conocimiento sobre los TTM. La encuesta incluyó cuatro dominios: a) patofisiología; b) psicofisiología; c) trastornos psiquiátricos y d) dolor crónico. Se usaron las respuestas otorgadas con un consenso de expertos como estándar de referencia1 para evaluar el nivel global de conocimiento sobre los TTM. Los resultados mostraron que los docentes tuvieron un nivel global de conocimiento del 55% de acuerdo al estándar de referencia. El dominio psicofisiológico indivi dualmente fue el mejor reconocido con el 77% de acuerdo con los expertos; las respuestas correctas en los otros dominios oscilaron entre el 38% y el 56%. El presente estudio demostró la necesidad de incorporar educación sobre los TTM estandarizada en la currícula de las escuelas o facultades de odontología en las universidades mexicanas. Hasta que esto suceda, las generaciones de odontólogos no tienen el conocimiento ni la experiencia necesarios para diagnosticar y manejar a los pacientes con Trastornos Temporomandibulares.

Association of temporomandibular dysfunction and stress in university students / Asociación de disfunción temporomandibular y estrés en estudiantes universitarios

The aim of this study was to evaluate the influence of emotional factors in temporomandibular disorders (TMD) in university students. The universe of this study consisted of 696 students of both sexes, from the University of Passo Fundo (UPF) - RS, who signed the free and informed consent term and received the Fonseca's Questionnaire, in order to verify the level of TMD and the Social Readjustment Rating Scale (SRRS), to evaluate the degree of stress level, at the beginning and end of the semester, beginners and graduating students. Data were tabulated and statistically analyzed using the Chi-Square test, with the significance level of 5%. From the total, 489 (70.25%) subjects had some degree of TMD, being the light TMD the most prevalent (309) in all areas of knowledge, with no statistical difference between the studied areas (p= 0.004). There was correlation between TMD and stress-SRRS (r= 0.217). There is a low percentage of individuals who are free from TMD. The correlation between TMD and stress was weak in all studied groups, regardless the area of knowledge, academic period and school grade.

El objetivo de este estudio fue evaluar la influencia de los factores emocionales en los trastornos temporomandibulares (TTM) en estudiantes universitarios. Fueron estudiados 696 estudiantes de ambos sexos, de la Universidad de Passo Fundo (UPF) - RS, que recibieron el Cuestionario de Fonseca, con el fin de verificar el nivel de TTM y la Escala de Reajuste Social (ERS), para evaluar el grado de nivel de estrés, en dos momentos distintos, al principio y al final del semestre, tanto en estudiantes que ingresaron a la Universidad como en estudiantes que se gradúan. Los datos fueron tabulados y analizados estadísticamente mediante la prueba de chi-cuadrado, con un nivel de significación del 5%. Del total, 489 (70,25%) sujetos tenían algún grado de TTM, siendo el tipo leve de TTM el más frecuente (309) en todas las áreas del conocimiento, sin diferencia estadística entre las áreas estudiadas (p= 0,004). No hubo correlación entre los TTM y el estrés-ERS (r= 0,217). Existe un bajo porcentaje de las personas que están libres de TTM. La correlación entre los TTM y el estrés era débil en todos los grupos estudiados, independientemente del área de conocimiento, periodo académico y grado escolar.

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)

Is there an association between anxiety/depression and temporomandibular disorders in college students?

Objective: Considering the high incidence of Temporomandibular Disorders (TMD) in the population aged 15-30 years and the fact that students are exposed to stressful psychosocial factors, the purposes of this study were: to verify clinical symptoms and jaw functionality in college students with TMD according to the anxiety/depression (A/D) level and to evaluate the correlation between A/D and functionality, maximum mouth opening (MMO) and pain and muscle activity. Material and Methods: Nineteen students with TMD diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders underwent two assessments during an academic semester. The evaluations were based on questionnaires (MFIQ - Mandibular Function Impairment Questionnaire; HADS - Hospital Anxiety and Depression Scale), clinical measurements (MMO without pain, MMO and assisted MMO; palpation of joint and masticatory muscles), and electromyography. The HADS scores obtained in the two assessments were used to classify all data as either "high" or "low" A/D. Data normality, differences and correlations were tested with the Shapiro-Wilk test, Student's t-test (or the Wilcoxon test), and Spearman test, respectively. The alpha level was set at 0.05. Results: None of the clinical variables were significantly different when comparing low and high A/D data. In low A/D there was a significant correlation between HADS score and: MFIQ (P=0.005, r=0.61), and MMO without pain (P=0.01, r=-0.55). Conclusions: Variation in A/D level did not change clinical symptoms or jaw functionality in college students with TMD. Apparently, there is a correlation between TMJ functionality and A/D level, which should be further investigated, taking into account the source of the TMD and including subjects with greater functional limitation. .

Painful temporomandibular disorders, self reported tinnitus, and depression are highly associated / Disfuncao temporomandibular dolorosa, auto-relato de zumbido e depressao estao fortemente associados

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. .

Objetivo Investigar a associação entre disfunção temporomandibular (DTM) dolorosa, auto-relato de zumbido e níveis de depressão. Método A amostra foi composta por 224 indivíduos com idades de 18 a 76 anos. O Research Diagnostic Criteria for Temporomandibular Disorders , eixo I, foi usado para classificar a DTM e o eixo II para obtenção do auto-relato de zumbido e dos níveis de depressão. Para a análise dos dados, foi aplicado o teste odds ratio (OR) com intervalo de confiança (IC) de 95%. Resultado Somente a presença de DTM dolorosa estava significativamente associada aos níveis de depressão moderado/severo (OR=9,3, 95%; IC: 3,44-25,11). A presença concomitante de DTM dolorosa e auto-relato de zumbido aumentaram a magnitude da associação com os níveis de depressão moderado/severo (OR=16,3; 95% IC: 6,58-40,51). Conclusão Disfunção temporomandibular dolorosa, altos níveis de depressão e auto-relato de zumbido estão fortemente associados. Entretanto, o desenho do estudo não permite estabelecer uma relação causal entre essas três entidades. .

The influence of patient's motivation on reported pain during orthodontic treatment

INTRODUCTION: Patients usually experience pain during orthodontic treatment. This fact can affect cooperation and the development of treatment. Reporting pain during treatment seems to be influenced by emotional aspects such as the patient's motivation. OBJECTIVE: To assess the relationship between patient's motivation and the intensity of reported pain during two stages of treatment. METHODS: Twenty males (11-37 years old) answered a questionnaire divided into five categories regarding their motivation towards treatment. The subjects were studied for 14 days (7 days with bonded brackets and 7 days with the initial arch inserted) and the intensity of pain was evaluated on a daily basis. All the issues, including the intensity of pain, were measured through the visual analog scale (VAS). RESULTS: The VAS-associated questionnaire proved to have good temporal reliability and reasonable internal consistency, being that the "perceived severity" domain had the greatest, although not significant (p = 0.196) correlation with pain intensity. Only the question asking the patients if they thought that their teeth were too uneven showed a positive correlation with pain intensity (p = 0.048). CONCLUSION: The results seem to indicate that the five categories related to treatment motivation cannot be used to predict discomfort during treatment. In addition, patients who think their teeth are too uneven may experience more severe pain due to greater force application after insertion of the initial arch.

INTRODUÇÃO: experiências de dor são relatadas rotineiramente pelos pacientes durante o tratamento ortodôntico, o que pode prejudicar a cooperação e o desenvolvimento do tratamento. Os relatos de dor parecem ser influenciados por fatores emocionais, como a motivação para o tratamento. OBJETIVO: avaliar a correlação existente entre a motivação para o tratamento ortodôntico e a intensidade de dor relatada pelos pacientes durante duas fases iniciais do tratamento. MÉTODOS: vinte indivíduos homens, com 11 a 37 anos de idade, foram avaliados por meio de um questionário dividido em cinco domínios relacionados à motivação para tratamento ortodôntico. Os indivíduos foram acompanhados durante 14 dias, sendo 7 dias apenas com os braquetes colados e 7 dias com o arco inicial inserido, sendo a intensidade de dor avaliada diariamente. Todas as questões, assim como intensidade da dor, foram mensuradas por meio da Escala Visual Análoga (EVA). RESULTADOS: o questionário associado à EVA apresentou boa confiabilidade temporal e consistência interna razoável, sendo que o domínio "Severidade percebida" apresentou a maior correlação com a intensidade de dor, apesar de não significativa (p = 0,196). Na análise das questões, apenas a que avaliou se os pacientes julgavam seus dentes muito tortos apresentou correlação positiva com a intensidade de dor (p = 0,048). CONCLUSÃO: os resultados indicam que os cinco domínios relacionados à motivação para o tratamento ortodôntico não podem ser utilizados para predizer o desconforto durante o tratamento, porém o fato de o indivíduo julgar seus dentes tortos pode indicar experiências de dor mais intensas devido à maior aplicação de força após a inserção do arco inicial.

Medical conditions and body pain in patients presenting orofacial pain / Condições médicas e dores corporais em pacientes com dor orofacial

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.

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.

Orofacial pain and temporomandibular disorders: the impact on oral health and quality of life

Many conditions may cause painful symptoms in orofacial structures. Among the chronic conditions that affect this area, temporomandibular disorders are the most common. Temporomandibular Disorder is a collective term that includes a number of clinical complaints involving the masticatory muscles, the Temporomandibular Joint and associated structures. In some cases, these complaints can be associated with depression, catastrophizing behavior and impact on quality of life. The present study aims to explain the relationship between Temporomandibular Disorders and pain chronification and their relation to a variety of psychosocial and behavioral comorbid conditions. The mechanisms of pain conduction and suggestions for management are also addressed.

Temporomandibular disorder and generalized joint hypermobility: application of diagnostic criteria / Disfunção têmporo-mandibular e hipermobilidade articular generalizada: aplicação de critérios diagnósticos

Generalized joint hypermobility (GJH) has been considered a predisposing factor for the development of temporomandibular disorder (TMD). AIM: To evaluate clinical and psychosocial aspects in individuals diagnosed with TMD with or without GJH. MATERIALS AND METHODS: Clinical and experimental study, which enrolled 34 women, from 18 to 35 years of age with TMD diagnosed by RDC/TMD. The GJH was assessed by the Beighton score and volunteers were broken down into 2 groups: with GJH (n = 22) and without GJH (n = 12). RESULTS: We found a high percentage of GJH (64. 71 percent). All participants had myofascial pain; 79. 41 percent had arthralgia and 41 percent had disk displacement. There was a correlation between higher GJH scores and higher passive mouth opening amplitude (p=0. 0034), with pain (p=0. 0029) and without pain (p=0. 0081). Greater mandibular range of motion was observed in the group with GJH, except for protrusion. Painful mouth opening was statistically higher in the GJH group (p=0. 0279). CONCLUSIONS: Individuals with TMD associated or not to GJH do not differ significantly regarding clinical and psychosocial aspects, except in the mandibular opening range of motion, which if kept at physiological levels can lead to a late diagnosis of TMD in these individuals.

A hipermobilidade articular generalizada (HAG) é uma condição sistêmica considerada como fator contribuinte para o desenvolvimento de sinais e sintomas da disfunção têmporo-mandibular (DTM). OBJETIVO: Avaliar aspectos clínicos e psicossociais de indivíduos com DTM associada ou não à HAG. Material e Método: Consistiu de um estudo clínico e experimental do qual participaram 34 mulheres, com idades entre 18 e 35 anos, diagnosticadas com DTM pelos Critérios diagnósticos para pesquisa em DTM (RDC/TMD). A HAG foi avaliada pelo Escore de Beighton e os voluntários divididos em 2 grupos: com HAG (n=22) e sem HAG (n=12). RESULTADOS: Verificou-se elevado percentual de HAG (64,71 por cento). Todos os participantes apresentaram dor miofascial, 79. 41 por cento artralgia e 41 por cento desordens discais. Houve correlação entre maiores escores de HAG e maior amplitude de abertura bucal passiva (p=0,0034), com (p=0,0029) e sem dor (p=0,0081). Observaram-se maiores amplitudes de movimento mandibular no grupo com HAG, exceto para a protrusão. A abertura com dor foi significativamente maior no grupo hipermóvel (p=0,0279). CONCLUSÕES: Indivíduos com DTM associada ou não à HAG não diferem significativamente quanto aos aspectos clínicos e psicossociais avaliados, exceto quanto à amplitude de abertura mandibular, cuja manutenção em níveis fisiológicos pode levar ao diagnóstico tardio de DTM nestes indivíduos.

Trait anxiety affects the orofacial nociceptive response in rats

The aims of the present study were to assess the influence of: a) trait anxiety on orofacial pain; and b) orofacial pain on state anxiety. Forty-four rats were initially exposed to the free-exploratory paradigm for the evaluation of their anxiety profiles. In accordance to the parameter "Percentage of time in the novel side", the animals were considered as presenting high or low levels of trait anxiety when presenting values below the 1st quartile, or above the 3rd quartile, respectively. A week later, formalin-1.5% was injected into the upper lip of each animal. The behavioural nociceptive response, characterized by increased orofacial rubbing (OR), was quantified for 30 minutes, as follows: Total time OR (0-30 minutes: total pain), 1st phase OR (0-6 minutes: neurogenic pain), and 2nd phase OR (12-30 minutes: inflammatory pain). Immediately after this test, but still under the effect of formalin, the rats were submitted to the Elevated Plus-maze test (EPM). The results showed that the high trait anxiety individuals presented higher frequency of OR than the low trait anxiety ones, except during the neurogenic pain period. However, no correlation was found between OR frequency and levels of state anxiety presented on the EPM. In conclusion, the animals presenting higher anxiety profiles were the most susceptible to orofacial pain, nevertheless, orofacial pain did not influence state anxiety.

Relationship between psychological factors and symptoms of TMD in university undergraduate students

Temporomandibular disorders is a collective term used to describe a number of related disorders involving the temporomandibular joints, masticatory muscles and occlusion with common symptoms such as pain, restricted movement, muscle tenderness and intermittent joint sounds. The multifactorial TMD etiology is related to emotional tension, occlusal interferences, tooth loss, postural deviation, masticatory muscular dysfunction, internal and external changes in TMJ structure and the various associations of these factors. The aim of this study was to evaluate the prevalence of the relationship between signs of psychological distress and temporomandibular disorder in university students. A total 150 volunteers participated in this study. They attended different courses in the field of human science at one public university and four private universities. TMD was assessed by the Research Diagnostic Criteria (RDC) questionnaire. Anxiety was measured by means of a self-evaluative questionnaire, Spielberger's Trait-State anxiety inventory, to evaluate students' state and trait anxiety. The results of the two questionnaires were compared to determine the relationship between anxiety levels and severity degrees of chronic TMD pain by means of the chi-square test. The significance level was set at 5%. The statistical analysis showed that the TMD degree has a positive association with state-anxiety (p=0.008; p<0.05) and negative with trait-anxiety (p=0.619; p<0.05). Moreover, a high TMD rate was observed among the students (40%). This study concluded that there is a positive association between TMD and anxiety.

Disfuncao temporomandibular e o termo usado para descrever uma serie de disturbios envolvendo as articulacoes temporomandibulares, musculos da mastigacao e oclusao, com sintomas comuns como dor, restricao de movimento, sensibilidade muscular e ruido articular intermitente. A etiologia da DTM e multifatorial e esta relacionada a tensao emocional, interferencias oclusais, perda de dentes, desvio postural, disfuncao muscular mastigatoria, mudancas internas e externas na estrutura da ATM, e a diferentes associacoes entre esses fatores. O objetivo deste estudo foi avaliar a relacao entre estresse psicologico e sinais de desordem temporomandibular em estudantes universitarios. Um total de 150 voluntarios participaram deste estudo sendo alunos de uma universidade publica e quatro universidades privadas de diferentes cursos da area de ciencias humanas. A avaliacao da DTM foi realizada por meio do questionario Research Diagnostic Criteria (RDC). Para a avaliacao da ansiedade foi aplicado o questionario Ansiedade Traco-Estado de Spielberger. Os resultados dos niveis de ansiedade e dos graus de DTM dos dois questionarios foram comparados pelo teste do qui-quadrado, com nivel de significancia de 5%. A analise estatistica mostrou que o grau de DTM tem relacao positiva para a Ansiedade-Estado (p = 0,008, p <0,05) e negativa para a ansiedade-traco (p = 0,619, p <0,05), alem disso, foi observado alto indice de DTM entre os estudantes (40%). Por meio dos resultados obtidos e analisados neste estudo, concluiuse que havia uma associacao positiva entre DTM e ansiedade.

Validation of the multimedia version of the RDC/TMD axis II questionnaire in Portuguese

OBJECTIVE: The aim of the study was to validate the multimedia version of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis II Questionnaire in Portuguese language. MATERIAL AND METHODS: The sample comprised 30 patients with signs and symptoms of temporomandibular disorders (TMD), evaluated at the Orofacial Pain Control Center of the Dental School of the University of Pernambuco, Brazil, between April and June 2006. Data collection was performed using the following instruments: Simplifed Anamnestic Index (SAI) and RDC/TMD Axis II written version and multimedia version. The validation process consisted of analyzing the internal consistency of the scales. Concurrent and convergent validity were evaluated by the Spearman's rank correlation. In addition, test and analysis of reproducibility by the Kappa weighted statistical test and Spearman's rank correlation test were performed. RESULTS: The multimedia version of the RDC/TMD Axis II questionnaire in Portuguese was considered consistent (Crombrach alpha = 0.94), reproducible (Spearman 0.670 to 0.913, p<0.01) and valid (p<0.01). CONCLUSION: The questionnaire showed valid and reproducible results, and represents an instrument of practical application in epidemiological studies of TMD in the Brazilian population.

Percepção de mães sobre a síndrome da erupção dentária e suas manifestações clínicas na infância / Percepción de las madres acerca del síndrome de erupción dental y manifestaciones clínicas de la infancia / Mothers perception of dental eruption syndrome and its clinical manifestation during childhood

Objetivo Este estudo objetivou identificar a percepção de mães primíparas e multíparas sobre a erupção dentária e suas manifestações, ao mesmo tempo em que relacionou e discutiu a ocorrência destas manifestações a luz da literatura pertinente. Método Trata-se de um estudo qualitativo descritivo, onde os sujeitos foram 61 mães, com bebês na faixa etária entre 3 e 12 meses de idade, usuários do Hospital de Pediatria da UFRN, na cidade de Natal, RN, Brasil. Utilizou-se uma entrevista semi-estruturada para coleta das informações. A análise dos dados foi feita pelo Software ALCESTE 4.5, utilizando-se as variáveis primíparas, para designar mães com apenas um filho e multíparas para mães com dois filhos ou mais. Resultados A presença de sintomatologia foi relatada por 75 por cento das mães entrevistadas. A percepção das mães de ambas as classes, provavelmente reflete desconhecimento do processo de desenvolvimento infantil e convergem para a presença de sintomas clínicos atribuídos ao processo eruptivo, porém, o grande diferencial está na forma de apreensão desta realidade. As primíparas manifestam claramente que o conhecimento foi adquirido através do senso comum, enquanto que as multíparas reproduzem este mesmo conhecimento baseado na experiência com os filhos anteriores. Discussão Concluiu-se que durante essa fase de erupção dentária os profissionais tenham uma posição firme e definida, baseada em evidências fartamente colocadas pela literatura, da relação direta entre erupção dentária e sintomatologia geral, dando a devida atenção a cada paciente e suas queixas, para desmistificar e melhor compreender esse processo na sua totalidade.

Objective This study was aimed at identifying primiparous and multiparous mothers perceptions about tooth eruption and related symptoms as well as discussing such events occurrence in the light of the relevant literature. Methods The research adopted a qualitative, descriptive design; 61 mothers who had already given birth to babies aged 3 to 12 months old were studied. Their children were outpatients at Rio Grande do Norte Federal Universitys Paediatric Hospital in Natal, RN, Brazil. A semi-structured interview was used for collecting data. ALCESTE 4.5 software was used for analysing data based on primiparous and multiparous mothers as variables; the former term referred to mothers bearing a child for the first time and multiparous to those who had born more than one child. Results Symptomatology was related by 75 percent of the mothers interviewed here. The perception of the mothers from both groups probably pointed to a lack of knowledge regarding child development and the process leading to the presence of clinical symptoms due to tooth eruption. However, the great difference lay in how this reality was perceived; mothers having a single child clearly affirmed that knowledge was acquired by common sense, whilst mothers of more than one child reproduced such knowledge according to their experience with previous children. Discussion It was concluded that during this phase of tooth eruption, professionals must adopt a firm and defined position based on the literature providing evidence of the real relationship between tooth eruption and general symptoms, paying attention to every patient and their complaints to demystify and better understand this whole process.

Objetivo Este estudio tuvo como objetivo identificar la percepción de las madres primíparas y multíparas en la erupción de los dientes y sus manifestaciones, así como examinar la ocurrencia de estos hechos a la luz de la documentación pertinente. Método La investigación tuvo un diseño cualitativo descriptivo y 61 madres cuyos bebés habían entre 3 y 12 meses de edad fueron estudiadas. Sus hijos eran pacientes del Hospital de Pediatría de la Universidad Federal de Rio Grande do Norte, en la ciudad de Natal, RN, Brasil. Para recoger los datos, se utilizó una entrevista semi-estructurada. El ALCESTE 4.5 fue utilizado para analizar los datos basados en las primíparas y multíparas madres como variables. El primero se utilizó para las madres que lleven a un niño por primera vez y multíparas que los cuales habían nacido más de un niño. Resultados La sintomatología fue referida por 75 por ciento de las madres entrevistadas. La percepción de las madres de ambos grupos probablemente señala desconocimiento del desarrollo del niño y el proceso converge a la presencia de síntomas clínicos debido a la erupción del diente. Sin embargo, la gran diferencia está en la forma de recoger esta realidad. Madres de un niño afirmaron claramente que el conocimiento fue adquirido por el sentido común, mientras que las madres de más de un niño se reproducen en este mismo conocimiento de acuerdo con la experiencia basada en los niños mayores. Discusión Se concluyó que durante esta fase de la erupción de los dientes, los profesionales deben tener una postura firme definida, basados por la literatura, la relación directa entre la erupción de los dientes y los síntomas generales, prestando atención a cada paciente y sus quejas, para así desmitificar y comprender mejor este proceso en su totalidad.

Influence of psychopathologies on craniomandibular disorders

Psychopathologies play a role in the etiology and maintenance of craniomandibular disorders (CMD). In this study, the craniomandibular index was applied to valuate signs and symptoms of CMD in 60 dentate patients, who were assigned to 2 groups: symptomatic (n=35) and asymptomatic (n=25). An interview on psychopathologies was carried out with the aim to detect the presence of some mood disorders, such as depression, dysthymic and bipolar I disorders. Among these disturbances, depression was the most significant aspect to be reported (p<0.05) since it was present in most symptomatic patients. This important interaction was also significantly correlated (p<0.05) with the Palpation Index. These results suggest that psychopathological aspects could increase muscle tenderness and pain in addition to sleep dysfuntions and other physical complaints. Therefore, psychopathologies should be regarded as an important aspect in patients with orofacial pains.

Os transtornos psíquicos podem desempenhar um importante papel na etiologia e manutenção das desordens craniomandibulares (DCM). Desta forma, neste estudo, foi aplicado o índice craniomandibular (ICM), o qual permite detectar a presença de sinais e sintomas de DCM em 60 pacientes totalmente dentados. Estes pacientes foram divididos em dois grupos: sintomáticos (n=35) e assintomáticos (n=25). Um teste psiquiátrico foi administrado para diagnosticar patologias psíquicas pertencentes ao DSM-IV, como a depressão e os transtornos distímico e bipolar I. Das patologias psíquicas relacionadas aos transtornos de humor, a depressão mostrou uma relação estatisticamente significante (p<0,05) com os pacientes sintomáticos para DCM. Ao analisar o índice de palpação separadamente, essa relação se manteve significante (p<0,05) numa escala crescente de valores, demonstrando a ação destes transtornos sobre a sintomatologia dolorosa muscular. Assim sendo, os transtornos mentais exerceriam uma influência considerável na etiologia da DCM, na medida em que potencializariam a dor. Isso ocorreria em função do aumento da tensão muscular, dos distúrbios do sono e de outras alterações fisiológicas advindas destes transtornos.

Psychological evaluation and cope with trigeminal neuralgia and temporomandibular disorder / Avaliação psicológica e enfrentamento na neuralgia trigeminal e disfunção temporomandibular

OBJECTIVE: To determine the psychological aspects of orofacial pain in trigeminal neuralgia (TN) and temporomandibular disorder (TMD), and associated factors of coping as limitations in daily activities and feelings about the treatment and about the pain. METHOD: 30 patients were evaluated (15 with TN and 15 with TMD) using a semi-directed interview and the Hospital Anxiety Depression (HAD) scale. RESULTS: TN patients knew more about their diagnosis (p<0.001). Most of the patients with TN considered their disease severe (87 percent), in opposite to TMD (p=0.004); both groups had a high level of limitations in daily activities, and the most helpful factors to overcome pain were the proposed treatment followed by religiosity (p<0.04). Means of HAD scores were 10.9 for anxiety (moderate) and 11.67 for depression (mild), and were not statistically different between TMD and NT (p=0.20). CONCLUSION: TN and TMD had similar scores of anxiety and depression, therefore patients consider TN more severe than TMD. Even with higher limitations, patients with TN cope better with their disease then patients with TMD.

OBJETIVO: Comparar aspectos psicológicos de dor orofacial entre neuralgia trigeminal (NT) e disfunção temporomandibular (DTM), e repercussões em atividades diárias, enfrentamento a representação da dor. MÉTODO: 30 pacientes foram avaliados (15 com NT, 15 com DTM) utilizando entrevista semi-dirigida e a Escala Hospitalar de Ansiedade e Depressão (HAD). RESULTADOS: Pacientes com NT sabiam melhor sobre seu diagnóstico (p<0,001). A maioria destes considerou sua doença grave (87 por cento), em oposição a pacientes com DTM (p=0,004); ambos tiveram um alto nível de limitações durante atividades diárias, e o tratamento seguido da religiosidade foram considerados os aspectos mais positivos para superação da dor (p<0,04). Não houve diferença estatística entre os grupos quanto a HAD (p=0,20), sendo a média dos índices foi 10,9 para ansiedade (moderada) e 11,67 para depressão (leve). CONCLUSÃO: Tanto pacientes com NT como pacientes com DTM apresentaram níveis semelhantes de ansiedade e depressão, entretanto pacientes com NT consideram sua doença mais grave do que os outros doentes. Mesmo com alto grau de limitações, seu enfrentamento da doença é melhor do que o enfrentamento de doentes com DTM.
