Even nowadays there is in Brasil a large number of edentulous and a precarious financial condition of most of the population. In addition, World Health Organization aims for oral health, which consists on the maintenance of a natural dentition, functional and aesthetic composed of at least 20 teeth, without need of prosthetic intervention throughout life. From this and considering the lack of researches about the permanence of edentulous spaces in the oral cavity, and also avoiding overtreatment, this research has been proposed. Thus, the aim was to evaluate the effect of different lengths of the shortened lower dental arch in the presence or absence of a removable partial denture (RPD) on masticatory function, quality of life and occurrence of temporomandibular dysfunction. To achieve this goal, we compared the masticatory efficiency (colorimetric test), the oral comfort through the analysis of the impact of oral health in quality of life (OHIP-14), the presence of temporomandibular dysfunction (RDC/TMD) and the general quality of life (WHOQOL) of patients with shortened dental arches (SDA) (n=60), which is an arch with a reduction of teeth starting posteriorly, and patients with complete dental arch (Complete DA) (n = 34). The group of patients whit SDA was divided among PPR wears (PPD + SDA) (n = 17) and non-wears (n = 43). The population of this study consisted on patients who received or looked for treatment at the clinics of the Department of Dentistry of UFRN, from clinical analysis and records. The sample was chosen by convenience. For statistical analysis, it was a database in SPSS 17.0, followed by descriptive analysis with frequencies, absolute values, tests of central tendency and variability. The statistical tests used were chi-squared and analysis of variance as well as Tukey s post test, when applicable, all with a 95% confidence level. The results shown a prevalence of TMD of 47,1% among patients using PRP and 69,8% among those who didn t, but this result wasn t statistically significant. The mean of the results of masticatory efficiency, WHOQOL and OHIP didn t show association to the presence or absence of PPR and to the lower number of occlusal units of the patients (0, 1, 2 or more occlusal). The association only occurred among the different groups of SDA and the patients with complete dental arch. Taking into account the results, it could be observed that studied patients with low posterior support using lower PRP didn t have better masticatory efficiency, general quality of life, less impacts of their oral conditions in quality of life or not even less temporomandibular dysfunction or better masticatory efficiency when compared to those who didn t use the prosthesis

The epidemiology of temporomandibular disorders varies widely in the literature. The aim of this study was to determine the prevalence of TMD in dental students of the Federal University of Rio Grande do Norte assessed by different indexes. The sample consisted of 101 individuals selected by a randomized process, whose general outline was systematic sampling. For evaluation of the signs and symptoms of TMD, an anamnestic index, Fonseca s protocol, and two clinical indexes, the RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders), or standard index, and the Helkimo s Clinical Dysfunction Index were applied. Data were analyzed using the chi-square test and kappa, besides verifying the sensitivity and specificity (5% significance). The diagnosis of TMD by different indexes showed a variation in the prevalence between 72.3% (Helkimo s Clinical index), 64.4% (Fonseca s anamnestic index) and 35.6% (RDC/TMD). There was no statistical difference between the sexes for the RDC/TMD, although this difference was found for Fonseca s and Helkimo s indexes (p<0.05). The most frequent type of TMD were joint disorders (Groups II and III), and the subtypes disc displacement with reduction (17.8%) and arthralgia (15.8%). Most individuals showed a mild TMD (45.5%) for both indexes, Fonseca and Helkimo. When comparing the types of diagnoses, RDC/TMD with Fonseca and Helkimo, low agreement was found (k=0.17 and k= 0.35, respectively). A moderate correlation between the severity of TMD was obtained (kw= 0.53) for Fonseca s protocol and Helkimo s index. High sensitivity and low specificity were seen for both diagnoses compared to standard, resulting in excessive false positives. Within the limitations of the study, it was concluded that the prevalence of TMD can vary widely, depending on the index used for its diagnosis

OBJETIVO: avaliar a freqüência dos sinais e sintomas, dos hábitos parafuncionais e das características oclusais de 80 crianças, pacientes da clínica de Ortodontia Preventiva da Faculdade de Odontologia de Araçatuba - UNESP. METODOLOGIA: o exame clínico constituiu-se de avaliação das características oclusais do paciente e observação da presença de hábitos parafuncionais. As crianças foram submetidas a uma entrevista, supervisionadas pelos pais, cujas perguntas relacionavam-se com os sinais e sintomas da disfunção. RESULTADOS E CONCLUSÕES: concluiu-se que os sinais e sintomas mais freqüentes foram o hábito de ranger os dentes, dores de cabeça e ruídos na ATM. A onicofagia e o bruxismo foram os hábitos parafuncionais mais prevalentes. A freqüência de sinais e sintomas da disfunção temporomandibular pode ser verificada em crianças por meio da entrevista e exame clínico minucioso.

Objetivou-se neste estudo verificar a associação da classe econômica e do estresse com a ocorrência de disfunção temporomandibular (DTM). A população deste estudo constituiu-se de uma amostra estatisticamente significativa de 354 indivíduos de ambos os sexos, pertencentes a diferentes classes econômicas da zona urbana do município de Piacatu, São Paulo, Brasil. Para isso, utilizou-se o Critério de Classificação Econômica Brasil (CCEB) para a estratificação econômica da população. Retirou-se uma amostra de cada estrato, na qual aplicou-se o Questionário de Fonseca para verificar o grau de DTM, e a Escala de Reajustamento Social (SRRS) para verificar o grau de estresse. Os dados coletados foram tabulados por meio do programa Epi Info 2000, versão 3.2, e analisados estatisticamente por meio do Teste Qui-Quadrado, com nível de significância de 5%. Os chefes das famílias foram assim distribuídos: 4 famílias pertencentes à Classe A2, 14 à Classe B1, 25 à Classe B2, 112 à Classe C, 174 à Classe D e 25 à Classe E. Após a análise estatística não foi observada associação significativa entre classe econômica e disfunção temporomandibular (DTM); entretanto, a mesma ocorreu entre estresse e DTM (p<0,01). A classe econômica não influencia na ocorrência de DTM, mas existe associação direta entre estresse e disfunção temporomandibular.

CONTEXTUALIZAÇÃO: Disfunção temporomandibular (DTM) é um termo coletivo que engloba vários problemas clínicos envolvendo a musculatura da mastigação, as articulações temporomandibulares (ATM) e suas estruturas associadas, com alta prevalência nas populações. OBJETIVOS: Sabendo-se que estudos brasileiros vêm utilizando o instrumento proposto por da Fonseca et al. (1994) para diagnóstico da severidade desta disfunção, realizou-se este estudo com o objetivo de verificar e estimar a consistência interna e a reprodutibilidade do mesmo. MÉTODOS: O delineamento amostral adotado foi o probabilístico, e participaram 1230 indivíduos moradores da cidade de Ribeirão Preto (SP), maiores de 18 anos de idade. As entrevistas foram realizadas por um único entrevistador por meio de ligações telefônicas. Para estudo da consistência interna, calculou-se o Coeficiente de Kuder-Richardson (kr-20) e para estimar a reprodutibilidade, utilizou-se a estatística Kappa (κ). RESULTADOS: A consistência interna do formulário foi de 0,5594, apontando para uma validação abaixo do desejado. Observou-se maior contribuição das questões 1, 2, 3, 6 e 7 para o coeficiente kr-20 total e maior consistência do instrumento quando composto apenas pelas mesmas (0,7044). Observou-se reprodutibilidade Boa e Ótima para as questões. CONCLUSÕES: Frente ao exposto, sugere-se que o formulário proposto por da Fonseca et al. (1994) seja adaptado, ficando composto apenas pelas questões 1, 2, 3, 6 e 7 da versão inicial, colaborando, assim, para aumento da confiabilidade do instrumento. Deve-se ressaltar ainda a necessidade da realização de estudos de validade para assegurar adequadas características psicométricas à nova versão do instrumento.

This paper presents the results of an applied qualitative study with dental students and professionals who work with people suffering from temporomandibular disorder. The aim was to investigate the way that dental practitioners and students perceive patients affected by this disorder, how they feel faced with the patients' suffering, and the importance they assign to a multidisciplinary approach, highlighting the treatments used. It is noteworthy that various factors are involved in the temporomandibular disorder framework, including emotional factors, as cited by the majority of the respondents. The data obtained indicated that the knowledge of the professionals and students related to caring for people with temporomandibular disorders was appropriate, however, important inadequacies were highlighted, such as the fact that professionals do not investigate the life history of the person in their psychosocial context.

Individuals with temporomandibular disorders (TMD) often have signs and symptoms such as intra-articular pain, muscle spasm, neck pain radiating from others who interfere with this balance. Over time can lead to postural changes and correction of the cervical spine, anterior head and shoulder asymmetry. The aim was to verify the effects of manual therapy on posture in subjects with TMD. Materials and methods: 30 volunteers (mean: 21.43± SD:1.43) of both sexes who had TMD classified according to axis I of the Research Diagnostic Criteria participated in this study. These were photographed in the anterior frontal and sagittal planes for analysis of the following angles (acromion clavicular joint, sternoclavicular joint, orbicular external, corners of the mouthand and protruding head). After, the volunteers were divided into groups ATM (manual therapy in the treatment of temporomandibular joint), Cervical (manual therapy in the treatment of cervical joint) and Control. The Kolmogokov-Smirnov test, followed by ANOVA, considering a significance level of 5% was used. Results: Groups ATM, Cervical and Control were considered homogeneous with respect to the values of the angles measured. These also showed no significant difference between the 1st, 5th and 10th sessions, so the manual therapy techniques applied to the TMJ and Cervical groups were not sufficient to change postural alignment. Conclusion: The postural alignment, the TMD patients evaluated in this study did not change after attending the sessions proposals with manual therapy techniques in the cervical and TMJ.

INTRODUCTION: Temporomandibular disorders (TMD) have association with psychological manifestations. OBJECTIVE: The aims of this study were to correlate the severity of TMD and the level of self-esteem, and to investigate sex‑related differences. MATERIAL AND METHOD: We evaluated 57 subjects of both gender, with mean age of 20.28 ± 2.07 years, through the Fonseca Anamnesis Index (FAI) and Rosenberg Self-esteem Scale (RSS). Correlations between variables were performed using the Spearman correlation coefficient; comparisons between the genders were performed using the Mann-Whitney test. It was considered a significance level of 5%. RESULT: No differences were found for the comparisons between the gender in the FAI (p = 0.79) and the RSS (p = 0.90). RSS correlates with the FAI in women (p = 0.01), but in men this result does not occur (p = 0.07). CONCLUSION: We concluded that women are more likely to have emotional disturbances resulting from changes in the temporomandibular joint than men.
