ABSTRACT Objective: To estimate the prevalence of developmental defects in dental enamel and its possible association with prenatal, neonatal and postnatal conditions in six-year-old schoolchildren in a southern Brazilian municipality. Methods: A cross-sectional study was conducted involving 655 six-year-old schoolchildren. Sociodemographic and health data were collected through interviews with mothers and children’s oral examinations at schools. Multivariate analyses were performed using Poisson regression with robust estimator. Results: The prevalence of developmental defects of enamel was 44.0%. Demarcated opacities were the most prevalent, followed by diffuse opacities. Late pregnancy, maternal schooling less than eight years, female gender and child’s white skin color were independently associated with the prevalence of demarcated opacities. Conclusions: The prevalence of developmental defects in dental enamel was 44.0%. Late pregnancy, maternal schooling less than eight years, female gender and child’s white skin color were associated with the prevalences.

RESUMO Objetivo: Estimar a prevalência de defeitos de desenvolvimento do esmalte dentário e sua possível associação com fatores pré-natais, neonatais e pós-natais em escolares de seis anos de idade em um município do sul do Brasil. Métodos: Foi conduzido um estudo transversal envolvendo 655 escolares de seis anos de idade. Os dados sociodemográficos e de saúde foram coletados por meio de entrevistas com as mães e exames bucais das crianças nas escolas. As análises multivariadas foram realizadas por meio de regressão de Poisson com estimador robusto. Resultados: A prevalência de defeitos de desenvolvimento do esmalte foi de 44,0%. As opacidades demarcadas foram as mais prevalentes, seguidas das difusas. Gravidez tardia, escolaridade materna inferior a oito anos, sexo feminino e cor da pele branca da criança foram independentemente associados à prevalência de opacidades demarcadas. Conclusões: A prevalência de defeitos de desenvolvimento do esmalte dentário foi de 44,0%. Gravidez tardia, escolaridade materna inferior a oito anos de estudo, sexo feminino e cor da pele branca da criança estiveram associados às prevalências.

ABSTRACT Objective: To identify the association between individual and socioeconomic factors during the first thousand days of the child's life and the occurrence of risk behaviors for the development of malocclusions. Material and Methods: Cross-sectional study. A sample of 655 6-year-old schoolchildren and families was included. Interviews with mothers were performed at home. The dependent variables were risk behaviors to the development of malocclusions. Independent variables were socioeconomic conditions, aspects of gestation, birth and health of the child up to two years of age. Bivariate and multivariate analyzes were performed through Poisson regression. Results: Maternal education of less than eight years was independently associated with the interruption of exclusive breastfeeding until the fourth month (PR=1.58 CI 95%; 1.07; 2.37). Occupation of the mother with income [PR=1.26; 1.02; 1.56)], occupation of the father without income [PR=1.46 (1.01; 2.14)] were associated fwith interruption of breastfeeding until the sixth month. Pregnancy in adolescence [PR=0.83 (0.70; 0.98)] and nursery attendance [PR=1.15 (1.02; 1.28)] were associated with bottle use. Nursery attendance [PR=1.27 (1.01; 1.59)], hospitalization in the first 29 days of life [PR=1.34 (1.01; 1.80)], occurrence of reflux [PR=1.30 (1.01; 1.70)] were associated with pacifier using. Conclusion: Variables related to the period of the first thousand days of life are associated with higher risk behaviors for the occurrence of malocclusions.

ABSTRACT Objective To determine the maternal and early childhood factors associated with asthma and obesity in children aged 6 to 7 years. Methods A case-control study conducted with children aged 6 to 7 years. Applications with questions about asthma symptoms in the last 12 months, maternal and childhood data in the first 2 years of life, and anthropometric data were collected. Children who presented asthma symptoms were considered as cases and those without asthma symptoms were considered as controls, later divided into two subgroups that were eutrophic or overweight/obesity. Logistic regression was performed to estimate the association between asthma symptoms (adequate weight and overweight/obesity) and gestational and personal factors, calculating odds ratio and 95% confidence interval (95%CI). Values of p<0.05 were considered significant. Results Two hundred and one children were evaluated, 25.4% had asthma symptoms, 37.2% of them were overweight/obesity. Waist circumference, triceps skinfold, and body mass index were higher in the group with overweight/obesity asthma symptoms compared to no asthma symptoms (p<0.05). Factors significantly associated with asthma and overweight/obesity symptoms included: the maternal history of asthma (odds ratio of 3.73; 95%CI: 1.10-12.6) and hypertension during pregnancy (odds ratio of 3.29; 95%CI: 1.08-9.94). Conclusion Maternal history of asthma and hypertension during pregnancy increased the chances of children, at 6 and 7 years of age, having symptoms of asthma and obesity.

ABSTRACT Objective: To estimate the prevalence and associated factors of dental trauma in 6-year-old school children in the city of Palhoça, Brazil. Material and Methods: Cross-sectional study nested in a cohort study. It involved a representative sample of school children born in 2009, residing in the municipality and regularly enrolled in public and private schools (n = 1,102). Clinical data were obtained through oral exams. To evaluate the incisal overjet, the distance in millimeters was measured horizontally from the labial surface of the lower central incisor to the labial surface of the upper incisor. Bivariate analyses were performed using the Chi-square test, with a p-value <0.05 considered statistically significant. Multivariate analyses using Poisson Regression were performed to identify independent associations between the prevalence and the independent variables studied. Results: Prevalence of dental trauma was 4.2% (95% CI 3.0-5.4). Dental trauma was statistically associated with studying in a private school (PR = 1.03; 95% CI 1.01-1.06) (p=0.016) and with inadequate lip coverage (PR = 1.08; 95% CI 1.01-1.14) (p=0.016). Conclusion: The prevalence of 4.2% of dental trauma in six-year-old children, associated with inadequate and greater lip coverage in children from private schools should be taken into account, since most teeth at this stage are newly erupted.

ABSTRACT Objective: To study the influence of the first thousand days of life on establishing determinant behaviors for dental caries in childhood. Material and Methods: Longitudinal retrospective study involving 664 children born in 2009 living in a southern Brazilian municipality was carried out. Data was collected through interviews with mothers and through child’s health card. Dependent variables were 1) tooth brushing onset after two years of age; 2) absent tooth brushing or once a day; 3) tooth brushing without adult supervision; 4) not having gone to the dentist until the age of 6; and 5) seek for dental services due to toothache at 6 years of age, over the last 30 days. Bivariate and multivariate analyses were performed using Poisson Regression to estimate relative risks (RR) and respective confidence intervals at the 95% accuracy level. Results: Mothers with lower schooling at child’s birth presented a higher risk of “child’s tooth brushing onset only after two years of age”, “brushing the teeth once a day only or not brushing” and with “child not having gone to the dentist until the age of 6”. Mothers who did not have a job when the child was born were associated with “not having gone to the dentist until the age 6”. Children with gastroesophageal reflux who underwent hospitalization for more than 2 days under age 2 were associated with “seeking dental services because of pain at 6 years of age over the last 30 days”. Conclusion: Higher risks of some determinant behaviors related to dental caries were associated with variables of the period of the first thousand days of life.

Abstract The aim of this report is to describe general and methodological characteristics of a cohort study in southern Brazil (Coorte Brasil Sul), aimed at understanding the impact of the first 1,000 days of life on children’s health. It is a cohort study involving all children born in 2009 and their families living in the municipality of Palhoça, State of Santa Catarina, Brazil. Face-to-face interviews with parents at home using a structured questionnaire and children’s physical and clinical examinations at schools have been carried out. Cross-sectional analyzes, longitudinal comparisons and hierarquical regression analysis will allow understanding if the first 1,000 days of life can influence on 6-year-old children’s health. The Coorte Brasil Sul is in its retrospective phase together with the children’s physical data collection. Preliminary data (n=1270) related to nutritional status point to a high prevalence of overweight (16.4%) and obesity (15.5%). With the continuity of the study, it is expected to evaluate if the first phases of life can influence health during adolescence and in adult life, mainly in relation to chronic diseases.

RESUMO Objetivo: Estudar o impacto do trauma dental na qualidade de vida relacionada a saúde oral entre escolares brasileiros. Métodos: Foi realizado estudo transversal envolvendo uma amostra representativa de escolares (n = 435), em uma cidade no sul do Brasil. Os dados sobre trauma dental foram coletados através de exames orais utilizando os critérios do O’Brien (1993), restritas a fraturas dentais e avulsões. A versão brasileira dos impactos no desempenho diário (OIDP) foi utilizado para recolher dados sobre o impacto na qualidade de vida relacionada à saúde bucal. O teste do qui-quadrado foi utilizado para a análise bivariada com níveis de significância de p <0,05. As razões de prevalência (RP) e intervalos de confiança (95%) foram estimados utilizando regressão de Poisson log-linear com um estimador robusto. Resultados: A prevalência de trauma dental foi de 7,2%, e foi associado com as seguintes dimensões: realização de atividades cotidianas [(RP = 3,52 (IC 95%, 1,06-11,75)] (p = 0,040), e falar [(PR = (IC 95%, 1,24-10,86) 3,67] (p = 0,019) após o ajuste para sexo, idade, cárie dentária e maloclusão. Conclusão: A prevalência de traumatismo dentário encontrado entre esta população era baixa, mas significativamente associada à qualidade relacionada à saúde bucal de vida.

ABSTRACT Objective: To study the impact of dental trauma on the oral health-related quality of life among Brazilian students. Methods: A cross-sectional study involving a representative sample of students of the public schools (n = 435) in a city in southern Brazil was carried out. Data on dental trauma were collected through oral examinations using the O’Brien’s criteria (1993) restricted to fractures and avulsions. The Brazilian version of the Oral Impacts on Daily Performances (OIDP) was used in order to collect data on the impact of oral health-related quality of life. Bivariate and multivariate analysis were performed through Poisson log-linear regression with robust estimator with significance levels set at p <0.05. Prevalence ratios (PR) and confidence intervals (95%) were estimated. Results: The prevalence of dental trauma was 7.2%, and it was associated with the following dimensions: performing daily activities [(PR = 3.52 (95% CI, 1.06-11.75)] (p = 0.040), and speaking [(PR = 3.67 (95% CI, 1.24-10.86)] (p = 0.019) after adjusting for sex, age, dental caries and malocclusion. Conclusion: The prevalence of dental trauma found among this population was low, but significantly associated with oral health-related quality of life.

Resumo Introdução A cárie dentária na adolescência continua sendo um importante problema de saúde pública; entretanto, a sua relação com os fatores psicológicos é pouco estudada. Objetivo Estudar a possível associação entre aspectos de autoestima e cárie dentária em adolescentes. Material e método Estudo transversal envolvendo amostra de 409 adolescentes de 13 municípios do sul do Brasil. A cárie foi avaliada segundo critérios da Organização Mundial da Saúde e a autoestima, pela Escala de Rosenberg. O teste do qui-quadrado foi utilizado para determinar a significância estatística das associações. Para ajustar para variáveis de confusão, foi utilizada a regressão loglinear de Poisson com estimativa robusta. Resultado Foram observadas associações positivas entre presença de dentes cariados e alguns aspectos da escala de autoestima: “Às vezes, eu acho que não presto para nada” (p <0,001); “Eu gostaria de poder ter mais respeito comigo mesmo” (p=0,016), e “Eu, com certeza, me sinto inútil, às vezes” (p=0,022). Associação negativa foi observada com: “No conjunto, eu estou satisfeito comigo” (p=0,022). Na análise ajustada, os adolescentes com dentes cariados apresentaram maior prevalência de respostas positivas para a questão “Às vezes, eu acho que não presto para nada” [RP= 1,23 (IC 95% 1,05; 1,44)] e maior prevalência de respostas negativas para a questão “No conjunto, eu estou satisfeito comigo” [RP= 1,12 (IC 95% 1,02; 1,24)]. Conclusão Aspectos da autoestima foram, independente e significativamente, associados com a presença de dentes cariados.

Abstract Introduction Dental caries in adolescents remains an important public health problem, but its relationship with psychological factors are poorly studied. Objective To study the possible association between aspects of self-esteem and dental caries in adolescents. Material and method A cross-sectional study involving a sample of 409 adolescents from 13 Southern Brazilian municipalities was carried out. Dental caries status was assessed through the World Health Organization criteria. For questions related to self-esteem the Rosenberg Self-Esteem Scale was used. The outcomes were each question of the scale. The chi-square test was used to determine statistical significance of associations. To adjust for confounding variables, the Poisson loglinear with robust estimator was used. Result Positive associations were observed for the presence of decayed teeth and “At times, I think I am no good at all” (p<0.001), “I wish I could have more respect for myself” (p= 0.016), “I certainly feel useless at times” (p= 0.022) and negative association with “On the whole, I am satisfied with myself” (p= 0.022). In the adjusted analysis, adolescents with decayed teeth had a higher prevalence of positive responses to “At times, I think I am no good at all” [(PR= 1.23 (CI 95% 1.05; 1.44)], and negative responses for “On the whole, I am satisfied with myself” [(PR= 1.12 (CI 95% 1.02; 1.24)]. Conclusion Aspects of self-esteem were significantly and independently associated with the presence of decayed teeth.

O objetivo deste estudo foi propor um modelo para a avaliação da qualidade da atenção à saúde bucal da criança. O marco conceitual para a elaboração da matriz avaliativa foi composto por estudos de avaliação de serviços de atenção à saúde bucal no Brasil e em outros países, e levantamento e revisão das políticas públicas vigentes relacionadas à saúde da criança no Brasil. A qualidade da gestão municipal na atenção básica da saúde bucal infantil foi avaliada sob duas dimensões: Gestão e Provimento. Na primeira, foram dispostas duas subdimensões: articulação e recursos, e na segunda, mais duas subdimensões: promoção e prevenção, e diagnóstico e tratamento. A matriz de avaliação ficou composta por nove indicadores na dimensão de Gestão e nove na dimensão de Provimento. Os indicadores foram elaborados em oficinas com especialistas. O modelo tem condições de ser aplicado em municípios com diferentes portes populacionais, e permite identificar os pontos nos quais os gestores devem aperfeiçoar suas ações.

This article proposes a model for quality evaluation of oral health care in children. The conceptual framework for the evaluation matrix consisted of evaluation studies on oral health care services in Brazil and other countries and a survey and review of prevailing public policies for children's health in Brazil. Two dimensions, Management and Provision, were evaluated in the quality of municipal management of pediatric oral health care. Management included two component dimensions, articulation and resources, while Provision included two more, "promotion and prevention" and "diagnosis and treatment". The evaluation matrix consisted of nine indicators in the Management dimension and nine in the Provision dimension. The indicators were elaborated in workshops with specialists. The model proved appropriate for application in municipalities with different population sizes and allows identifying the areas where managers should improve their actions.

Introdução: O câncer de lábio, boca e faringe é um sério problema de saúde. Altas taxas de incidência são encontradas no mundo. No Brasil, as regiões Sul e Sudeste são as que apresentam maiores taxas de incidência. Objetivo: Descrever a taxa de sobrevida em cinco e dez anos em portadores de câncer de lábio, boca e faringe atendidos em um centro de referência de Florianópolis, SC. Métodos: Estudo de coorte histórica, realizado com dados de pacientes que tiveram diagnóstico entre 1º de janeiro e 31 de dezembro de 2001 e acompanhados até 31 de dezembro de 2011. Foi realizada análise descritiva e estimada a sobrevida pelo método de Kaplan-Meier. O modelo semiparamétrico de Cox foi utilizado para estimar o risco de óbito. Resultados: As taxas de sobrevida ao final de 5 e 10 anos foram de 33,3 e 26,9%, respectivamente. O estadio clínico avançado ao momento do diagnóstico aumentou em 2,88 e 2,51 o risco de óbito, respectivamente. Sexo, etnia, nível de escolaridade, diagnóstico e tratamento prévios, bem como idade, não se mostraram significativamente associados. Conclusão: As taxas de sobrevida aos 5 anos foi de 33,3% e, aos 10 anos, foi de 26,9%. O estadio avançado mostrou-se como fator de risco independente para o óbito por câncer de lábio, boca e faringe nos dois períodos analisados.

Introduction: Cancer of the lip, mouth and pharynx is a serious health problem. High incidence rates are found worldwide. In Brazil, the Southern and Southeastern regions have the highest incidences in the country. Objective: To describe 5 and 10-year survival rates in patients with cancer of the lip, mouth and pharynx at a referral center in Florianopolis, Santa Catarina, Brazil. Methods: Retrospective cohort study using data from patients diagnosed between January 1st and December 31st, 2001, with follow-up until December 31st, 2011. Descriptive analysis was performed and survival was estimated by Kaplan-Meier method. Cox semi-parametric model was used to estimate death risk. Results: Survival rates at 5 and 10 years were 33.3 and 26.9%, respectively. Advanced clinical stage in the diagnosis increased death risk by 2.88 and 2.51, respectively. Sex, ethnicity, level of education, previous diagnosis and treatment, as well as age, did not show significant association. Conclusion: Survival rate at 5 years was 33.3% and, at 10 years, was 26.9%. Advanced stage was an independent risk factor for death due to cancer of the lip, mouth and pharynx in both periods analyzed.

O tabagismo tem sido apontado como uma epidemia, e a prevenção ao hábito é indicada como prioridade máxima para a saúde pública das nações. Este é um estudo do tipo observacional e transversal envolvendo uma amostra representativa da população adulta de município do sul do Brasil com o intuito de conhecer a prevalência do consumo do tabaco e o perfil do tabagista. A prevalência de fumantes foi de 17,3%, sendo que o sexo feminino representou 54,9% da amostra. Neste estudo, o tabagismo ocorreu predominantemente em pessoas com idade superior a 39 anos (p<0,001), com escolaridade de até oito anos de estudo (p<0,001), com índices de depressão verificados pelo Inventário de Beck para Depressão considerados como moderado ou grave (p=0,001) e com baixa renda familiar (p<0,029). O município apresenta alta prevalência de consumo de tabaco, que afeta, predominantemente, a população acima de 39 anos de idade, com menor renda e com menor escolaridade. Este estudo evidencia ainda uma associação entre depressão moderada a severa e o hábito do tabagismo.

The tobacco consumption has been pointed as an epidemic and the prevention to the smoking habit is indicated as high priority for the public health of the nations. This is an observational cross-sectional study comprising a representative sample of an adult population in a Southern Brazilian city aiming to know the tobacco consumption prevalence and the profile of the smoker. Smokers' prevalence was 17.3% and female subjects were 54.9% of the sample. Smoking occurred predominantly in subjects with age older than 39 years (p<0.001), with less than eight years of education (p<0.001), with moderate and severe scores of depression measured by Beck Depression Inventory (p=0.001) and low familiar income (p=0,029). The district shows high prevalence of smokers which are predominantly subjects older than 39 years, with low income and education. This study also showed an association with moderate or severe depression and the smoking habit.
