The objective of this research was to verify the association between verbal bullying and untreated dental caries. The present cross-sectional study had a representative sample of 1,589 children, aged 8-10 years, from public schools. Information on verbal bullying related to the oral condition was obtained through a questionnaire directed to the students. Clinical data were collected by 4 calibrated examiners (kappa > 0.70) using the DMFT/dmft and PUFA/pufa indexes for caries. Socioeconomic issues were answered by those responsible. The prevalence of verbal bullying related to the oral condition was 27%. The results of the Poisson regression, in an adjusted multiple model, showed a significant association between bullying and untreated caries lesions (prevalence ratio, PR: 1.27; 95% CI: 1.07-1.52), PUFA/pufa index (PR: 1.34; 95% CI: 1.11-1.61), pulp involvement (PR: 1.35; 95% CI: 1.09-1.67), and abscess (PR: 1.74; 95% CI: 1.18-2.56). It was concluded that children with untreated dental caries had a higher prevalence of verbal bullying when compared to caries-free or disease-treated children.

Enamel fracture had no significant impact on children's quality of life, while enamel-dentin fracture did have an impact on quality of life.

The proportion of students taking active trips was higher when going to work than to school. All indicators were associated with the mode of commuting, except gender and place of residence for commuting to work.

OBJETIVO: este estudo se propôs a avaliar a influência da quantidade de exposição gengival na estética do sorriso para os sexos feminino e masculino, e se existe diferença de opinião entre ortodontistas, clínicos gerais e pessoas leigas. MÉTODOS: utilizaram-se fotografias da face durante o sorriso de um indivíduo do sexo feminino e de um indivíduo do sexo masculino. As fotos foram alteradas digitalmente para produzir cinco diferentes níveis de exposição gengival, que variaram de exposição gengival de 4mm até a cobertura dos incisivos superiores pelo lábio superior em 4mm. As fotografias foram impressas em tamanho real da face, dispostas aleatoriamente em um álbum e foram classificadas por 30 ortodontistas, 30 clínicos gerais e 30 leigos, quanto à atratividade do sorriso, em péssimo, ruim, regular, bom ou ótimo. RESULTADOS: o sorriso mais estético para o indivíduo do sexo feminino, tanto para ortodontistas, clínicos gerais e leigos, foi aquele em que o lábio superior repousa na margem cervical dos incisivos superiores, mostrando toda a coroa dos incisivos (p<0,05). Para o indivíduo do sexo masculino, o sorriso mais estético, para pessoas leigas, foi com o lábio na altura da margem cervical dos incisivos superiores (p<0,05), sendo que ortodontistas e clínicos gerais consideraram tanto o lábio na altura da margem cervical como o lábio superior cobrindo os incisivos superiores em 2mm como os mais estéticos (p<0,05). CONCLUSÕES: a estética do sorriso para mulheres e homens foi influenciada pela quantidade de exposição gengival, havendo diferença de opinião entre ortodontistas, clínicos gerais e leigos.

Rev Bras Educ Fís Esporte, (São Paulo) 2016 Jul-Set; 30(3):757-68 • 757 Physical activity and environment in men and women IntroductionPhysical activity at leisure, transportation, social support and urban environment perception in women and men in Florianópolis/SC CDD. 20.ed. 613 Regular physical activity (PA) has been pointed as an important component of a healthy life style 1 . Increase in physical activity levels and a healthy life style can reduce the risk of coronary diseases and in uence the rate of mortality by chronic diseases 2 . However, studies from Brazil and other countries show that the population is not su ciently physically active 3 and the increase of sedentary behavior has been a crescent concern for public health policies [4][5] .One possibility to change population attitude towards physical activity is to identify associated factors that can make possible the implementation of public policies and strategies that contribute to an active life style adoption 6 . e models that try to explain the prevalence of physical activity in leisure and transport are multifactorial and consider psychosocial, sociodemographic factors and, more recently, urban environmental characteristics in di erent populations and contexts [7][8][9][10] . ere is evidence that some attributes of the perceived urban environment are associated with practice of physical activity during leisure (LFA) and transport (TFA) [11][12] . Individuals that mentioned having AbstractThe aim of the study was to identify characteristics of the perceived physical environment and social support associated with physical activity during leisure (LFA), and transportation (TFA) in man and women. The study was based on a systematic sample of 746 residents in Florianópolis, SC, Brazil, obtained by phonebook. We utilized the long version of International Physical Activity Questionnaire (IPAQ), and the scale of active mobility in the community environment (news adapted). The outcomes investigated were not meeting the recommendations for physical activity (NARAF) in LFA and TFA in man and women. As explanatory variables we investigated the characteristics of socio-demographic variables, perception of the environment, general health, and body mass index (IMC). We performed logistic regression analysis to estimate the odds ratios and the adjusted attributes of the physical environment and social support of man and women that NARAF. The response rate was 91% (n = 746). The prevalence of women in NARAF in transportation was 73.3% (69.1-77.5%) and for men was 71.1% (66.1 to 76.2%). In the LFA NARAF prevalence of women was 78.4% (74.5-78.3%) and 74.9% (70.1-79.7%) in men. In TFA environmental attributes associated with less chance of NARAF were: live in an area close to shopping areas, gym and bank branch close to home. In the LFA, street lighting, security during the day, walking site close to home and live near the coastline. Programs to promote AFL in adults should consider variables of the urban environment (lit streets, safety, local walking or phys...

Background Malocclusion is a condition frequently seen in primary dentition due to the interaction of environmental, genetic and behavioural factors. The occurrence of some types of malocclusions can have an impact on oral health-related quality of life in children. Hence, the present study aimed to verify the impact of primary dentition malocclusion on oral health-related quality of life in preschool children. Methods A population-based cross-sectional study was conducted in Florianopolis, Brazil, with a representative sample of 1050 preschoolers aged between 2 and 5 years, randomly selected. Parents answered the Brazilian version of the Early Childhood Oral Health Impact Scale and also to a questionnaire on socio-economic indicators. Data obtained from the questionnaire were obtained by item response theory based on model of gradual response. The malocclusion assessed was: anterior open bite, increased overjet and posterior crossbite. Poisson regression model was employed for multivariate analysis (P < 0.05). Results Malocclusion was observed in 36.7% of the children. Of these, 11.4% were anterior open bite, 67.2% were increased overjet, and 21.4% were posterior crossbite. Malocclusion's impact on oral health-related quality of life was 28.6%. In children aged 4–5 years, the prevalence of malocclusion’s impact on quality of life was 49.5% higher than in children aged 2–3 years. Statistical analysis showed that preschool children with malocclusion showed no significant impact on quality of life. Conclusions The findings of the present study indicate that the occurrence of primary dentition malocclusion has no impact on the quality of life of children aged 2–5 years.

Objective: To determine the prevalence of bruxism, associating it with mouth breathing in preschool children in Florianopolis, Brazil. Material and Methods: Clinical examination and questions to parents/guardians of 429 children aged 2-5 were conducted. The clinical examination was performed by three calibrated examiners to register the presence of tooth wear on incisors and molars. The questions were related to sleep bruxism (teeth grinding) and mouth breathing. For determinate diagnosis, were "possible" bruxism by the American Academy of Sleep Medicine and "probable" bruxism, whereas the Item Response Theory was employed for mouth breathing. To determine the associations, a Chi-square test and Fisher exact test with a standard error of 5% and 95% interval confidence were applied. Results: The clinical examination revealed bruxism in 8.2%, whereas the parental report revealed bruxism in 17.2%. When clinical examination was associated with the parent's report, bruxism was present in 2.1%. Among the non-clinical variables, the most prevalent changes included: child presenting a regular stuffy nose (19.6%), followed by child is always open-mouthed (16.1%). A significant statistical association between bruxism and age was obtained (p<0.05), the age group with prevalence of 4 and 5 years old with 68.9%. There was no mouth breathing association with the presence of bruxism (p>0.05). Conclusion: Bruxism was prevalent for children aged 4-5 and bruxism had no association with mouth breathing.

Observando a tendência de ensinar Machine Learning (ML) já na educação básica, surge também a necessidade de avaliação da aprendizagem. Com o objetivo de assegurar uma avaliação confiável e válida, apresentamos a avaliação de uma rubrica para a avaliação da aprendizagem da aplicação de conceitos de ML com base nos resultados da aprendizagem de 108 alunos do ensino fundamental e médio. Tanto a análise da confiabilidade (Coeficiente Ômega de 0,646) quanto a análise da validade convergente do construto por meio da matriz de correlação policórica indicam a possibilidade de duas dimensões. Mesmo indicando a necessidade de revisão com uma amostra maior, esses resultados já podem auxiliar na aplicação da rubrica.
