The purpose of the present study was to evaluate the relationship between psychological variables and the clinical diagnosis of temporomandbular disorders (TMD) in 12-year-old adolescents. TMD pain was assessed by RDC/TMD examination (Research Diagnostic Criteria for Temporomandibular Disorders) (Axis I and II). Five-hundred and fifty-eight subjects (330 girls and 228 boys) were examined. Bivariate analyses were performed using the Chi-square test (chi(2)). The logistic regression models were adjusted estimating the Odds Ratios (OR), their 95% confidence intervals (CI), and significance levels. Only 2.19% of the boys and 8.18% of the girls presented one of the Axis I categories. All variables from axis II were related to TMD diagnosis (p < 0.001). Gender was significantly related to TMD diagnosis (p = 0.0028). The risk of TMD incidence for girls was 3.5 times higher than that for boys (Odds Ratio = 3.52, Confidence Interval 1.31-9.43). The individuals who presented the variable 'characteristics of pain intensity' (CPI) higher than 0 had 31 times more risk of TMD incidence (Odds Ratio = 31.361, Confidence interval 6.01-163.5). We concluded that psychological variables and female gender are important risk indicators related to TMD incidence, even in adolescents.

Objectives: The aim of this study was to determine the risk indicators for signs and symptoms of temporomandibular dysfunction (TMD) in children between 4 and 12 years of age. Study Design: One hundred six patients were assessed for the following variables:(1) signs and symptoms of TMD (deviation when opening mouth, joint noises, limitation of movement, pain in the mandible or during movement), (2) dentition and occlusal abnormalities, and 3) habits (pacifier sucking, nonnutritive sucking, finger sucking, nail biting, and teeth grinding (bruxing). Multivariate logistic regression was performed with the level of significance set at P &lt; 0.05. Results: The prevalence of at least one sign or symptom of TMD in the present sample was 12.26%(n = 13). Only bruxing (P = 0.01, odds ratio 6.08, CI 1.51–24.51) and posterior crossbite (P = 0.03, odds ratio 5.74, CI, 1.18–27.85) achieved statistical significance in the multivariate regression model and were considered risk indicators for signs and symptoms of TMD. Conclusions: Children with bruxing or clenching habits and those with posterior crossbite have a greater likelihood of developing signs and symptoms of TMD.

The present study investigated the distribution profile of dental caries and its association with areas of social deprivation at the individual and contextual level. The cluster sample consisted of 1,002 12-year-old schoolchildren from Piracicaba, SP, Brazil. The DMFT Index was used for dental caries and the Care Index was used to determine access to dental services. On the individual level, variables were associated with a better oral status. On the contextual level, areas were not associated with oral status. However, maps enabled determining that the central districts have better social and oral conditions than the deprived outlying districts.

Patients under beta-blockers therapy presented reduced non-stimulated salivary flow when compared to controls, without influencing the sense of taste or masticatory performance. The use of anxiolytics did not affect salivary flow and taste perception in the studied sample.

As feiras livres são um importante espaço de comercialização dos produtos da agricultura familiar, indo muito além disso: é também espaço de socialização, identidade regional e cultural e também de articulação política. Assim, este trabalho analisa a dinâmica da feira dos agricultores familiares do município de Conceição do Mato Dentro, Minas Gerais. Ao analisar a problemática dos produtores feirantes e seu relacionamento com outros atores sociais, procurou-se compreender os aspectos econômicos, através da representação na renda dos agricultores, na gestão autônoma dos feirantes, na movimentação da economia local e no seu potencial para fortalecimento e expansão, além dos aspectos socioculturais, nas relações de pertencimento estabelecidas neste espaço. Metodologicamente a pesquisa, de natureza qualitativa, utilizou-se de entrevistas, conversação e observação como instrumentos de coleta de dados, tendo por grupo de entrevistados feirantes, consumidores e comerciantes. Os resultados mostram que a feira gera trabalho e renda no campo, dinamiza a economia local e oferta a soberania e segurança alimentar para a população urbana, além de ser espaço privilegiado de organização e participação social.

The purpose of this study was to assess the transit of poultry, as well as the inspection on the outbreak of diseases, by addressing the issues concerning the system of the National Program on Poultry Sanity and its legal resolutions. The data on the animal transportation and the occurrence of the diseases were collected from the official services. A legislation-based assessment was also carried out for the period from 2008 to 2012 in the state of Sergipe, Brazil. Results showed an intense transit of poultry in just about all towns of the state in the period under study, especially in chicken farms where less number of poultry is bred: from 5,000 to 15,000. Besides, 64% of poultry transportation was found to be intermunicipal. The state of Sergipe has received poultry particularly from the states of Pernambuco (49.87%), Bahia (20.85%), Minas Gerais (5.94%), Paraíba (5.16%), and Goiás (5.05%). The number of transit indicates an increase in transit over the years. In addition, three of six municipalities which saw these diseases (Estância, São Cristóvão and Itaporanga d'Ajuda) are responsible for a great part of the poultry transit. Results also showed that the majority of activities of the State Program on Poultry Sanity would be carried out in the municipalities where a larger poultry marketing flow takes place, thereby seeking to record a greater number of notifications on the diseases and, then, carry out the surveillance activities. Therefore, regarding the poultry transit, it is recommended to do a mapping of the risk regions for poultry diseases, as well as studies about the epidemiological characterization of the municipalities of the state of Sergipe.

The objective of the study was to develop regression models to describe the epidemiological profi le of dental caries in 12-year-old children in an area of low prevalence of caries. Two distinct random probabilistic samples of schoolchildren (n=1,763) attending public and private schools in Piracicaba, Southeastern Brazil, were studied. Regression models were estimated as a function of the most affected teeth using data collected in 2005 and were validated using a 2001 database. The mean (SD) DMFT index was 1.7 (2.08) in 2001 and the regression equations estimated a DMFT index of 1.67 (1.98), which corresponds to 98.2% of the DMFT index in 2001. The study provided detailed data on the caries profi le in 12-year-old children by using an updated analytical approach. Regression models can be an accurate and feasible method that can provide valuable information for the planning and evaluation of oral health services. DESCRIPTORS:Child. Dental Caries. DMF Index.

RESUMOO objetivo do estudo foi desenvolver modelos de regressão para delinear o perfi l epidemiológico da cárie dentária em localidade com baixa prevalência de cárie aos 12 anos de idade. Foram examinadas duas amostras probabilísticas (n=1.763) de indivíduos de escolas públicas e privadas de Piracicaba,(SP). Dados sobre os dentes mais afetados foram coletados em 2005 e validados utilizando um banco de dados (2001). A média (dp) do CPOD foi de 1,7 (2,08) em 2001 e os modelos de regressão desenvolvidos estimaram um CPOD de 1,67 (1,98) em 2005, o qual representa 98,2% do CPOD em 2001. Os resultados apresentaram detalhes do perfi l da cárie dentária aos 12 anos, usando uma abordagem analítica atual. Os modelos de regressão poderiam ser considerados como uma forma acurada e factível no auxílio do planejamento e avaliação dos serviços em saúde bucal. DESCRITORES:Criança. Cárie Dentária.

Although the teeth most affected by dental caries at present are practically the same as those 60 years ago, e.g. the fi rst permanent molars, the epidemiological profi le of the disease has completely changed. In the 1940s almost all individuals had caries experience while nowadays the highest caries scores are concentrated in a small number of individuals, 4 the so-called "polarization group". Thus, many questions arise about what the actual epidemiological profi le of dental caries would be; how the disease is distributed among the population; and what risk factors are associated. This demands the search for tools that would give a more accurate disease distribution profi le. The reduction in caries prevalence has been an ongoing process for years, and has brought about chan...

The aim of this study was to analyse mastication and the sense of taste in 39 patients submitted to cancer treatment in different areas of the body and to compare these variables with those of 44 control individuals within the same age range. The following aspects were assessed: dental status (DMFT); stimulated and non-stimulated salivary flow; sense of taste (salty, sweet, bitter and sour); and masticatory performance (MP), through the calculation of X(50). Logistic regression models were established to test the association between the independent variables and cancer treatment. Cancer patients had lesser stimulated salivary flow, a smaller number of teeth and occlusal units, worse MP, higher salty, sweet and sour taste scores and a lower bitter taste score (P < 0·05). A significant positive correlation was found between MP and the DMFT index in both groups (P < 0·05), meaning that a lower DMFT index value denoted a smaller X(50) value (better masticatory performance). The logistic regression model revealed that patients who had undergone cancer treatment had a greater probability of exhibiting a smaller number of teeth, higher salty and smaller bitter taste scores (P < 0·05). It was concluded that patients who were submitted to cancer treatment presented oral physiology alterations when compared with control subjects at the same age range.
