Family structure, sociodemographic factors and type of dental service associated with oral health literacy in the early adolescence / Estrutura familiar, fatores sociodemográficos e tipo de serviço odontológico associados ao alfabetismo em saúde bucal no início da adolescência

Abstract The aim of this study was to evaluate associations between oral health literacy and family, sociodemographic and dental service characteristics in early adolescents. A cross-sectional study was conducted with 740 schoolchildren. The following variables were investigated using validated questionnaires: oral health literary (BREALD-30), sociodemographic characteristics, type of dental service and family functioning (FACES III). Associations were tested using robust Poisson regression analysis (α=5%). Higher oral health literacy was associated with the female sex (RR=1.09; 95%CI: 1.03-1.14), connected type of family cohesion (RR=1.12; 95%CI: 1.05-1.20), rigid (RR=1.14; 95%CI: 1.04-1.25) and structured (RR=1.11; 95%CI: 1.04-1.20) types of family adaptability, more than eight years of mother's schooling (RR=1.16; 95%CI: 1.10-1.22), age of caregiver more than 38 years (RR=1.07; 95%CI: 1.02-1.13) and the use of private dental services (RR=1.06; 95%CI: 1.01-1.12). The level of oral health literacy in early adolescents was associated with sex, family structure, mother's schooling, caregiver's age and type of dental service used.

Resumo Este estudo avaliou a associação de fatores sociodemográficos, familiares e do tipo de serviço odontológico utilizado ao alfabetismo em saúde bucal em pré-adolescentes. Trata-se de um estudo transversal com 740 escolares. Foram avaliados o alfabetismo em saúde bucal (BREALD-30), fatores sociodemográficos, tipo de serviço odontológico e funcionalidade familiar (FACES III) por meio de questionários validados. A associação entre as variáveis foi avaliada por meio de regressão de Poisson robusta (α=5%). Um maior alfabetismo em saúde bucal foi associado ao sexo feminino (RR=1.09; IC95%: 1.03-1.14), coesão familiar do tipo conectada (RR=1.12; IC95%: 1.05-1.20), adaptabilidade familiar dos tipos rígida (RR=1.14; IC95%: 1.04-1.25) e estruturada (RR=1.11; IC95%: 1.04-1.20), escolaridade materna superior a oito anos de estudo (RR=1.16; IC95%: 1.10-1.22), idade do responsável superior a 38 anos (RR=1.07; IC95%: 1.02-1.13) e uso de serviços odontológicos privados (RR=1.06; IC95%: 1.01-1.12). O nível de alfabetismo em pré-adolescentes foi associado ao sexo, estrutura familiar, idade e escolaridade do responsável e tipo de serviço odontológico utilizado.

Family and contextual factors associated with licit drug use in adolescence

ABSTRACT OBJECTIVE: TO evaluate the family and contextual factors associated with licit drug use among 15 to 19-year-old adolescents in the school context. METHODS: This is a representative, school-based, cross-sectional study conducted with 746 adolescents from 15 to 19 years old enrolled in public and private schools. Parents/guardians reported on the sociodemographic variables, while adolescents answered questionnaires on drug use, family cohesion and adaptability, oral health literacy and visits to the dentist. Information on school context was obtained at the institution and via municipal publications. Associations between variables were analyzed using unadjusted and adjusted multilevel Poisson regression models. RESULTS: Prevalence of licit drug use at least once and a pattern indicative of harmful drug use were 39.8% and 15.1%, respectively. After the adjusted analysis of licit drug use at least once, the variables gender (PR = 1.26; 95%CI: 1.01-1.59), family cohesion (PR = 9.81; 95%CI: 1.23-72.54), and average income of the school district (PR = 0.72; 95%CI: 0.57-0.91) remained in the final model. As for drug abuse, only the detached type (PR = 23.01; 95%CI: 2.46-214.87) and separated type (PR = 13.54; 95%CI: 1.40-130.97) of family cohesion remained in the final model. CONCLUSION: Experience with licit drug use was associated with family and contextual factors among the adolescents, while family cohesion was the main factor related to harmful drug use.

Socioeconomic status and family functioning influence oral health literacy among adolescents

ABSTRACT OBJECTIVE Evaluate socio-demographic, family and behavioral factors associated with oral health literacy (OHL) in adolescents. METHODS Cross-sectional study conducted with adolescents aged 15 to 19 years in Campina Grande, Brazil. Parents/guardians answered a questionnaire addressing socio-demographic data. The adolescents answered validated instruments on family cohesion and adaptability (family adaptability and cohesion evaluation scale), drug use (alcohol, smoking and substance involvement screening test), type of dental service used for last appointment and OHL (Brazilian version of the Rapid Estimate of Oral Health Literacy in Dentistry). Two dentists were trained to evaluate OHL (K = 0.87-0.88). Descriptive analysis was performed, followed by Poisson regression analysis (α = 5%). A directed acyclic graph was used to select independent variables in the study. RESULTS The following variables remained associated with better OHL: high mother's schooling level (RR = 1.07; 95%CI: 1.03-1.12), high income (RR = 1.04; 95%CI: 1.01-1.09), white ethnicity/skin color (RR = 1.05; 95%CI: 1.01-1.10), married parents (RR = 1.04; 95%CI: 1.01-1.09), "enmeshed" family cohesion (RR = 1.21; 95%CI: 1.12-1.30), "structured" (RR = 1.06; 95%CI: 1.01-1.12) or "rigid" (RR = 1.11; 95%CI: 1.04-1.19) family adaptability, having more than five residents in the home (RR = 1.07; 95%CI: 1.01-1.14) and having used a private dental service during the last appointment (RR = 1.08; 95%CI: 1.03-1.13). CONCLUSION Family functioning and socio-demographic factors influence the level of oral health literacy among adolescents.

Degree of family cohesion and social class are associated with the number of cavitated dental caries in adolescents

Abstract The aim of this study was to evaluate the association between number of cavitated dental caries in adolescents and family cohesion, drug use, sociodemographic factors and visits to the dentist. A cross-sectional study was conducted with 746 adolescents aged 15 to 19 years from Campina Grande, Brazil. The parents answered a questionnaire addressing sociodemographic data, and the adolescents answered questionnaires on drug use, type of family cohesion and visits to the dentist. Two examiners underwent training and calibration exercises (K > 0.80) to diagnose dental caries using the Nyvad criteria. A directed acyclic graph was created to select the variables to be controlled in the statistical model. Associations between the independent variables and the outcome were determined using robust Poisson Regression analysis for complex samples (α = 5%). Rate ratios (RR) and 95% confidence intervals (CI) were calculated. The prevalence of dental caries and cavitated lesions among the adolescents was 92.8% and 41.6%, respectively. The following variables remained associated with the number of cavitated lesions in the multivariate analysis: disengaged (RR: 6.30; 95%CI: 1.24-31.88; p = 0.028 ), separated (RR: 4.80; 95%CI: 1.03-22.35; p = 0.046) and connected (RR: 5.23; 95%CI: 1.27-21.59; p = 0.024) levels of family cohesion, and high social class (RR: 0.55; 95%CI: 0.39-0.76; p = 0.001). In conclusion, this paper posits that adolescents with a lower socioeconomic status, and those whose family cohesion was classified as disengaged, separated or connected, had a larger number of cavitated lesions.

Bullying among adolescents and school measures to tackle it / Bullying entre adolescentes e medidas escolares para combatê-lo

Abstract Background Adolescents are particularly susceptible to the effects of negative social interactions. Thus, knowledge on the behavioral characteristics of adolescents who are targets of bullying can assist with establishing actions directed to protection of the victims. Objective Describe the types of bullying practice and how adolescents perceive this violence, as well as the methods adopted by school to tackle it. Method A cross-sectional study was conducted with 612 public school students aged 10-19 years. Data were collected through the application of a questionnaire developed by the UK-based Kidscape organization. Items were added to this questionnaire aiming to characterize the respondents and their perception regarding the conduct of school administrators in tackling the problem. Statistical analysis involved frequency description and measures of bivariate and multivariate association (α=5%). Results The prevalence of bullying was 21.7%. No significant associations were found between bullying and socio-demographic factors (p>0.05). In most cases, the onset of aggressions was at 6-11 years of age of the victim. Verbal aggression was the most frequently observed type of bullying (82.2%), and the classroom was the location where most aggressions occurred (60.2%). Installation of surveillance cameras was the main action taken by school administrators to tackle the problem. Conclusion Prevalence of bullying in the population studied may be considered high, and verbal aggression was the most frequent type of bullying. Actions of school administrators were concentrated on structural reforms.

Resumo Introdução Os adolescentes são particularmente suscetíveis aos efeitos das interações sociais negativas. Assim, o conhecimento das características comportamentais dos adolescentes alvos de bullying pode auxiliar no estabelecimento de ações voltadas à proteção das vítimas. Objetivo Descrever as formas de bullying e o modo como os adolescentes percebem essa violência, e os métodos adotados pela escola para combatê-la. Método Foi realizado um estudo transversal com 612 alunos de 10 a 19 anos de idade matriculados em escolas públicas. A coleta de dados foi realizada por meio de questionário desenvolvido pela instituição inglesa Kidscape, à qual foram adicionados itens para a caracterização dos respondentes e suas percepções sobre a conduta dos administradores escolares diante do problema. A análise estatística envolveu uma distribuição de frequência e medidas de associação bivariada e multivariada (α=5%). Resultados A prevalência de bullying foi de 21,7%. Não foram encontradas associações significativas entre bullying e fatores sociodemográficos (p>0,05). Na maioria dos casos, o início das agressões começou entre seis e 11 anos de idade da vítima. A forma verbal foi a mais frequente (82,2%) e a sala de aula foi a localidade onde ocorreu a maior parte das agressões (60,2%). A instalação de câmeras de segurança foi a principal ação tomada pelos administradores escolares para combater o problema. Conclusão A prevalência de bullying na população estudada pode ser considerada alta e o abuso verbal é a forma mais frequente. As ações dos administradores escolares concentraram-se em reformas estruturais.

Toothache and non-clinical individual and school factors in five-year-old children: multilevel analysis

Abstract The objective of the present study was to evaluate the influence of individual and contextual factors on the occurrence of toothache in five-year-old children. A cross-sectional study was conducted with 756 five-year-old children from public and private preschools in a city in the countryside of the northeast of Brazil. The sample was determined through probabilistic sampling in two stages (preschools and children). The children included could not have systematic diseases, permanent tooth or orthodontic treatment. Parents/caregivers were required to spend at least 12 hours per day with their children. The history of toothache during the life of the child was reported by parents/guardians. Socioeconomic and psychological questionnaires were completed by parents/guardians. Variables related to social context were obtained from the preschools in which the children studied and the official publications of the municipal region. Unadjusted and adjusted multilevel Poisson regression models were used to investigate the association between individual and contextual characteristics and history of toothache. The history of toothache was found for 23.8% of the children. Among the individual determinants, gender of the child, order of birth, and schooling of parent/guardian were associated with toothache in children. The individual variables remained associated with the outcome after the addition of the contextual variables to the model. The type of preschool was the contextual determinant associated with toothache in the final model. Both individual (gender, order of birth and schooling of parents/guardians) and contextual (type of preschool) determinants were associated with history of toothache in five-year-old children.

Resumo O objetivo do presente estudo foi avaliar a influência de fatores individuais e contextuais na ocorrência de dor de dente em crianças de cinco anos de idade. Um estudo transversal foi realizado com 756 crianças de cinco anos de idade de pré-escolas públicas e privadas em uma cidade no interior do Nordeste do Brasil. A seleção da amostra foi realizada por meio de amostragem probabilística em duas etapas (pré-escolas e crianças). As crianças incluídas não poderiam ter doenças sistêmicas, dentes permanentes ou tratamento ortodôntico. Foram incluídos apenas pais/responsáveis que passavam pelo menos 12 horas por dia com seus filhos. O histórico de dor de dente durante a vida da criança foi relatado pelos pais/responsáveis. Os questionários socioeconômicos e psicológicos foram preenchidos pelos pais/responsáveis. As variáveis relacionadas ao contexto social foram obtidas na pré-escola em que as crianças estudaram e nas publicações oficiais da região municipal. Os modelos de regressão de Poisson multinível não ajustados e ajustados foram utilizados para investigar a associação entre características individuais e contextuais e histórico de dor de dente. O histórico de dor de dente foi encontrado em 23,8% das crianças. Entre os determinantes individuais, gênero da criança, ordem de nascimento e escolaridade dos pais/responsáveis ​​foram associados com dor de dente em crianças. As variáveis ​​individuais permaneceram associadas ao resultado após a adição das variáveis ​​contextuais ao modelo. O tipo de pré-escola foi o determinante contextual associado ao histórico de dor de dente no modelo final. Tanto o indivíduo (gênero, ordem de nascimento e escolaridade dos pais/responsáveis) quanto os determinantes contextuais (tipo de pré-escolar) foram associados com o histórico de dor de dente em crianças de cinco anos de idade.

Evaluation of the association of bruxism, psychosocial and sociodemographic factors in preschoolers

Abstract The aim of the present study was to evaluate factors associated with sleep bruxism in five-year-old preschool children. A preschool-based cross-sectional study was conducted with 761 pairs of children and their parents/caregivers. Sleep bruxism was diagnosed using a questionnaire administered to the parents/caregivers, who also answered questionnaires addressing sociodemographic data and parent's/caregiver's sense of coherence. Clinical oral evaluations of the children to determine dental caries, traumatic dental injuries, malocclusion and tooth wear were performed by two researchers who had undergone a training exercise (interexaminer Kappa: 0.70 to 0.91; intraexaminer Kappa: 0.81 to 1.00). Descriptive analysis and logistic regression for complex samples were carried out (α = 5%). The prevalence of sleep bruxism among the preschool children was 26.9%. The multivariate analysis revealed that bruxism was associated with poor sleep quality (OR = 2.93; 95 CI: 1.52-5.65) and tooth wear (OR = 2.34; 95%CI: 1.39-3.96). In the present study, sleep bruxism among preschool children was associated with tooth wear and poor sleep quality of the child. In contrast, psychosocial aspects (sense of coherence) were not associated with sleep bruxism.

Use of psychoactive substances at least once in life among Brazilian university students at the beginning and end of courses and the associated factors / Uso de substâncias psicoativas pelo menos uma vez na vida entre estudantes universitários brasileiros no início e no final dos cursos e fatores associados

Methods A cross-sectional study conducted with a representative sample of 398 students in public university. The students answered a questionnaire validated for the evaluation of drug use and socio-demographic data. Poisson regression analysis was performed. Results A total of 56.3% and 13.3% of the students had used both legal and ilegal drugs. The following variables remained significantly associated with legal drug use in the final model: male sex (PR=1.48; 95%CI: 1.25-1.76), older age group (PR=1.23; 95%CI: 1.03-1.47), not living with parents (PR=1.20; 95%CI: 1.01-1.41), not having a religion (PR=1.37; 95%CI: 1.16-1.62) and taking a course in the health field (PR=1.33; 95%CI: 1.08-1.64). The following variables were significantly associated with ilegal drug use: male sex (PR=2.33; 95%CI: 1.35-4.02), older age group (PR=2.27; 95%CI: 1.28-4.02), higher monthly income (PR=1.73; 95%CI: 1.05-2.85) and not having a religion (PR=1.70; 95%CI: 1.02-2.84). Conclusion Legal and ilegal drug use at least once in life was associated with social factors, sex, age, income, religion, living situation and type of higher education course.

Conclusão O uso de drogas lícitas e ilícitas, pelo menos uma vez na vida, foi associado a fatores sociais, sexo, idade, renda, religião, situação de vida e tipo de ensino superior.

Oral Problems and Self-Confidence in Preschool Children

Abstract The aim of the present study was to evaluate the impact of clinical oral factors, socioeconomic factors and parental sense of coherence on affected self-confidence in preschool children due to oral problems. A cross-sectional study with probabilistic sampling was conducted at public and private preschools with 769 five-year-old children and their parents/caretakers. A questionnaire addressing socio-demographic characteristics as well as the Scale of Oral Health Outcomes for Five-Year-Old Children (SOHO-5) and the Sense of Coherence Scale (SOC-13) were administered. The dependent variable was self-confidence and was determined using the SOHO-5 tool. Dental caries (ICDAS II), malocclusion and traumatic dental injury (TDI) were recorded during the clinical exam. Clinical examinations were performed by examiners who had undergone training and calibration exercises (intra-examiner agreement: 0.82-1.00 and inter-examiner agreement: 0.80-1.00). Descriptive statistics and Poisson regression analysis were performed (a=5%). Among the children, 91.3% had dental caries, 57.7% had malocclusion, 52.8% had signs of traumatic dental injury and 26.9% had bruxism. The following variables exerted a greater negative impact on the self-confidence of the preschool children due to oral problems: attending public school (PR=2.26; 95% CI: 1.09-4.68), a history of toothache (PR=4.45; 95% CI: 2.00-9.91) and weak parental sense of coherence (PR=2.27; 95% CI: 1.03-5.01). Based on the present findings, clinical variables (dental pain), socio-demographic characteristics and parental sense of coherence can exert a negative impact on self-confidence in preschool children due to oral problems.

Resumo O presente estudo teve como objetivo avaliar a interferência de fatores clínicos bucais, socioeconômicos e senso de coerência (dos pais) no prejuízo de autoconfiança devido alterações de saúde bucal em pré-escolares. Um estudo transversal com amostra probabilística foi realizado em pré-escolas públicas e privadas com 769 crianças de 5 anos de idade e seus responsáveis. Questionários de variáveis sociodemográficas, o Scale of Oral Health Outcomes for Five-Year-Old Children (SOHO-5) e Sense of Coherence Scale (SOC-13) foram aplicados na amostra. A variável dependente foi autoconfiança e coletada a partir do questionário SOHO-5. Cárie dentária (ICDAS II), má oclusão e traumatismo dentário foram registrados durante o exame clínico. Exames clínicos foram realizados nos pré-escolares por examinadores previamente calibrados (acordo intra-examinador: 0,82-1,00 e acordo inter-examinador: 0,80-1,00). Análise descritiva e Regressão de Poisson foram aplicadas (a=5%). Entre as crianças avaliadas, 91,3% apresentaram cárie dentária, 57,7% maloclusão, 52,8% traumatismo dentário e 26,9% bruxismo. As seguintes variáveis mostraram uma maior média de prejuízo na autoconfiança dos pré-escolares devido alterações de saúde bucal: frequentar pré-escola pública (PR=2,26; 95% CI: 1,09-4,68), histórico de dor de dente (PR=4,45; 95% CI: 2,00-9,91) e fraco senso de coerência dos pais (PR=2,27; 95% CI: 1,03-5,01). Com base nos resultados, pode-se concluir que variáveis clínicas, como a dor de dente, sociodemográfica e senso de coerência dos pais podem interferir na autoconfiança devido a alterações de saúde bucal em pré-escolares.

O potencial impacto financeiro dos problemas bucais na família de pré-escolares / The potential financial impact of oral health problems in the families of preschool children

Resumo O objetivo do estudo foi avaliar a percepção dos pais/responsáveis quanto ao impacto financeiro dos problemas de saúde bucal na família de pré-escolares. Um estudo transversal, foi realizado com 834 crianças pré-escolares, em Campina Grande, Brasil. Pais/responsáveis responderam ao Early Childhood Oral Health Impact Scale (B-ECOHIS). O item “impacto financeiro” foi a variável dependente. Questionários de variáveis sociodemográficas, histórico de dor de dente e percepções de saúde foram administrados. Os exames clínicos foram realizados por três dentistas previamente calibrados (Kappa: 0.85-0.90). Estatística descritiva foi realizada, seguida de regressão logística para amostras complexas (α = 5%). A frequência de impacto financeiro devido a problemas de saúde bucal em pré-escolares foi de 7,7%. As seguintes variáveis foram significativamente associadas com o impacto financeiro: percepção ruim dos pais sobre saúde bucal, a interação entre histórico de dor de dente e ausência de cárie dentária e interação entre histórico de dor de dente e presença de cárie dentária. Pode-se concluir que na maioria das vezes os pais/responsáveis relatam impacto financeiro em decorrência da procura por tratamento tardio, principalmente pela presença de dor e complicações no quadro clínico.

Abstract The aim of the study was to evaluate the perception of parents/caregivers regarding the financial impact of oral health problems on the families of preschool children. A preschool-based, cross-sectional study was conducted with 834 preschool children in Campina Grande, Brazil. Parents/caregivers answered the Early Childhood Oral Health Impact Scale. “Financial impact” was the dependent variable. Questionnaires addressing socio-demographic variables, history of toothache and health perceptions were administered. Clinical exams were performed by three dentists previously calibrated (Kappa: 0.85-0.90). Descriptive statistics were performed, followed by logistic regression for complex samples (α = 5%). The frequency of financial impact due to oral health problems in preschool children was 7.7%. The following variables were significantly associated with financial impact: parental perception of child’s oral health as poor, the interaction between history of toothache and absence of dental caries and the interaction between history of toothache and presence of dental caries. It is concluded that often parents/caregivers reported experiencing a financial impact due to seeking treatment late, mainly by the presence of toothache and complications of the clinical condition.

Case-control study examining the impact of oral health problems on the quality of life of the families of preschoolers

Abstract The aim of this study was to evaluate the impact of dental caries, traumatic dental injuries (TDI), toothaches, and malocclusion on the oral health-related quality of life (OHRQoL) of the families of Brazilian preschool children. A population-based, matched case-control study involving 415 pre-schoolers aged 3-5 years was conducted. The case (impact on OHRQoL) and control groups (no impact on OHRQoL) were matched for age, gender, and family income at an 1:4 ratio. Impact on the OHRQoL of a family was assessed using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS). Dental caries, TDI, and malocclusion were diagnosed by three calibrated dentists (Kappa: 0.85-0.90). Data analysis involved descriptive statistics and conditional logistic regression analysis (p ≤ 0.05; 95%CI). There were no differences between the cases and controls regarding age, gender, and family income (p > 0.05). The most frequent responses on the B-ECOHIS among cases were "felt guilty" (68.6%) and "been upset" (48.2%). The following variables were significantly associated with negative impacts on family OHRQoL (cases): caries severity (OR = 6.680; 95%CI = 2.731-16.349), a history of toothache (OR = 2.666; 95%CI = 1.492-4.765), parental rating of the child's oral health as poor (OR: 1.973; 95%CI = 1.072-3.634), and parent's/caregiver's age (OR = 2.936; 95%CI = 1.077-3.478). Anterior open bite was positively associated with OHRQoL (OR = 4.050; 95%CI = 1.333-12.314). Caries severity, a history of toothache, parental rating of the child's oral health as poor, and younger parents/caregivers were associated with impact on the OHRQoL of the families of preschoolers.

Parental influence on children's answers to an oral-health-related quality of life questionnaire

Abstract The aim of the study was to evaluate parental influence on children's answers to an oral health-related quality of life (OHRQoL) questionnaire. A cross-sectional study was conducted with a non-probabilistic sample of 84 pairs of 5-year-olds and parents/guardians. The participants were selected from a primary family healthcare center in Campina Grande, Brazil. First, the children and parents answered respective versions of the Scale of Oral Health Outcomes for Five-Year-Old Children (SOHO-5). Seven days later, the children answered their version of the SOHO-5, without the presence of their parents/guardians, and underwent a clinical exam of dental caries, traumatic dental injury and malocclusion, by a previously calibrated researcher. Statistical analysis involved a comparison of mean scores and the calculation of the intraclass correlation coefficient (ICC). Poisson regression models were used to associate the variables (α = 5%). No significant differences were found between the mean SOHO-5 scores of the children when alone or accompanied by parents/guardians (p > 0.05). The ICC between the answers of the children alone or accompanied was 0.84. White spot (PR = 6.32; 95%CI: 1.36 - 29.40) and cavitated lesions (PR = 9.81; 95%CI: 3.22 - 29.85) had an impact on OHRQoL, according to the children's self-report, whereas cavitated lesions (PR = 90.52; 95%CI: 13.26 - 617.74) and anterior open bite (PR = 1.95; 95%IC: 1.07 - 3.53) remained on the final model, according to the parents' version of the SOHO-5. In conclusion, parents did not influence the children's responses, and dental caries are the oral health problem exerting the greatest impact on the children's OHRQoL.

Parental Perceptions of Oral Health Status in Preschool Children and Associated Factors

The aim of the present study was to evaluate parental perceptions of oral health status in preschool children. A cross-sectional study was carried with 843 Brazilian children between 3 and 5 years of age. Parents/guardians answered a self-administered questionnaire on the health of their children and sociodemographic data. Parental perceptions of their child's oral health were determined by the responses to the following question: "How would you describe your child's oral health?" The Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) was answered by parents/guardians and used to measure the impact of oral health-related quality of life (OHRQoL) on preschool children and their families. Three examiners performed oral exams on the children (K= 0.85-0.90). Descriptive analytical statistics were carried out, followed by logistic regression for complex samples (α=5%). The following variables were significantly associated with parental perceptions of children's oral health: parental perception of general health as poor (OR=18.25; 95% CI: 3.36-98.96), negative impact on family's OHRQoL (OR=13.82; 95% CI: 4.27-44.72), child aged five years (OR=7.40; 95% CI: 1.49-36.63) and the interaction between history of toothache and dental caries (OR=10.02; 95% CI: 1.17-85.61). Thus, parental perceptions of oral health are influenced only by clinical conditions with symptoms, such as dental caries with toothache. Other oral conditions, such as malocclusion or traumatic dental injury, were not associated with parental perceptions of their child's oral health.

O objetivo do presente estudo foi avaliar a percepção dos pais sobre saúde bucal de pré-escolares. Um estudo transversal foi realizado com 843 crianças brasileiras entre três e cinco anos de idade. Os pais/responsáveis responderam a um questionário autoaplicável sobre a saúde de seus filhos e dados sociodemográficos. Percepções dos pais sobre a saúde bucal de seus filhos foram determinados pela resposta à seguinte pergunta: "Como você descreveria a saúde bucal do seu filho?" A versão brasileira da Early Childhood Oral Health Impact Scale (B-ECOHIS) foi respondido por pais/responsáveis e usada para medir o impacto da qualidade de vida relacionada à saúde bucal (OHRQoL) em crianças pré-escolares e suas famílias. Três examinadores realizaram exames bucais nas crianças (K=0,85-0,90). Análise descritiva foi realizada, seguida de uma análise de regressão logística para amostras complexas (α=5%). As seguintes variáveis foram significativamente associados com a percepção dos pais sobre saúde bucal dos filhos: percepção ruim dos pais sobre a saúde geral (OR=18,25; IC 95%: 3,36-98,96), impacto negativo sobre OHRQoL da família (OR=13,82; IC 95%: 4,27-44,72), crianças com idade de cinco anos (OR=7,40; IC 95%: 1,49-36,63) e a interação entre o histórico da dor de dente e cárie dentária (OR=10,02; IC 95%: 1,17-85,61). Percepções parentais de saúde bucal são influenciados pelo impacto sobre OHRQoL da família, a percepção ruim dos pais sobre a saúde geral do seu filho, e as condições clínicas com sintomas, tais como cárie dentária com dor de dente. Outros problemas bucais, tais como má oclusão ou traumatismo dentário, não foram associados com a percepção dos pais sobre saúde bucal de seus filhos.

Predisposing Factors for Traumatic Dental Injury in Primary Teeth and Seeking of Post-trauma Care

The aim of the present study was to investigate predisposing factors for traumatic dental injury (TDI) in the primary dentition and seeking of dental care after the occurrence of TDI. A randomized population-based cross-sectional study was carried out with 814 children aged 3 to 5 years enrolled at public and private preschools in the city of Campina Grande, PB, Brazil. Parents were asked to fill out a questionnaire on demographic data and the child's history of TDI. TDI was evaluated by clinical examinations performed by three previously calibrated dentists (Kappa: 0.85 to 0.90). Bivariate and multivariate Poisson regression models were constructed for TDI and the parent-reported search for dental care (α=0.05). The prevalence of TDI was 34.6%. The most common type of TDI was enamel fracture (55.0%). The central incisors were the most frequently affected teeth (87.5%). Predictors for TDI in the primary dentition were household income >U$312.50 (PR: 1.355; 95% CI: 1.050-1.724) and overjet >2 mm (PR: 1.539; 95% CI: 1.219-1.942). The predictor for seeking dental care following TDI was parent's age >30 years (PR: 1.753; 95% CI: 1.039-2.960). Household income and overjet were associated with TDI. Among children having suffered TDI, parent's age is a crucial determinant for seeking dental care.

O objetivo do presente estudo foi avaliar os fatores predisponentes para o traumatismo dentário (TD) na dentição decídua e a procura por tratamento odontológico após a ocorrência do TD. Um estudo transversal de base populacional randomizado foi realizado com 814 crianças entre 3 e 5 anos de idade, matriculadas em pré-escolas públicas e privadas da cidade de Campina Grande, PB, Brasil. Um questionário foi preenchido pelos pais sobre dados sociodemográficos e histórico de TD da criança. TD foi avaliado através de exames clínicos realizados por três dentistas previamente calibrados (Kappa: 0,85-0,90). Modelos de regressão de Poisson bivariado e multivariado foram realizados para TD e a procura por tratamento odontológico após o TD (α=0.05). A prevalência de TD foi de 34,6%. O tipo mais comum de TD foi a fratura de esmalte (55,0%) e os incisivos centrais superiores foram os dentes mais acometidos (87,5%). Preditores para o TD na dentição decídua foram renda familiar >U$312.50 (RP: 1,355; IC 95%: 1,050-1,724) e overjet >2 mm (RP: 1,539; IC 95%: 1,219-1,942). O fator preditor para a procura de tratamento odontológico após TD foi a idade dos pais >30 anos (RP: 1,753; IC 95%: 1,039-2,960). Renda familiar e overjet foram associados com o TD. Entre as crianças que sofreram TD, a idade dos pais foi um determinante crucial para a procura de tratamento odontológico.

Conhecimento de alunos do curso de Educação Física sobre avulsão dentária / Knowledge of physical education students about tooth avulsion

Objetivo: Avaliar o conhecimento dos acadêmicos do 5° ao 8° período do curso de Educação Física do Centro Universitário de João Pessoa (UNIPÊ) sobre a avulsão dentária. Materiais e Métodos: Um estudo transversal foi realizado com 70 acadêmicos de Educação Física, de uma universidade particular. O conhecimento sobre avulsão dentária foi avaliado a partir de um questionário contendo 10 questões objetivas acerca do tema proposto. Os dados coletados foram analisados pelo Programa Estatístico SPSS v.13.0 etrabalhados sob forma de estatística descritiva, por meio de números absolutos e percentuais. Resultados:Um total de 64,3% informou não ter estudado na graduação assuntos referentes a traumatismos dentários e95,7% dos pesquisados afirmaram não terem atendido casos de avulsão dentária. Os participantes afirmaramque lavariam o dente com água da torneira (20.0%) e os manteriam em recipientes sem líquido (21.4%).Conclusão: Os acadêmicos possuem conhecimentos limitados e a maioria não conhece os procedimentospara atendimento imediato em casos de avulsão dentária. Dessa forma, há necessidade de implantação deprogramas de educação e formação em procedimentos de primeiros socorros em relação à avulsão dentária,direcionado à professores de educação física e alunos de todas as instituições de ensino.
