Abstract Investigate individual and contextual determinants associated with bullying in schoolchildren eight to ten years of age. A cross-sectional study was conducted with 739 schoolchildren, who answered a question about episodes of bullying related to oral health and questionnaires addressing childhood anxiety and orofacial dysfunction. The guardians provided information on sociodemographic characteristics, sleep disorders, and oral health literacy. Trained examiners assessed the children for the diagnosis of dental caries using the International Caries Detection and Assessment System, malocclusion using the Dental Aesthetic Index, orofacial dysfunction using the Nordic Orofacial Test-Screening and traumatic dental injury (Andreasen criteria) (Kappa> 0.80). The contextual variables were the type of school and the monthly income of the school neighborhood. Descriptive statistics was performed to characterize the sample and unadjusted and adjusted (p <0.05) multilevel Poisson regression models were run. The prevalence of bullying was 13.3%. After the adjusted analysis, malocclusion (PR=1.59; 95%CI:1.03-2.44) and anxiety (PR=1.79; 95%CI:1.10-2.93) remained associated with bullying. In terms of context, the monthly income of the neighborhood of the school was associated with bullying (PR=1.75; 95%CI:1.12-2.72). Malocclusion and anxiety influenced the occurrence of bullying. A lower average income in the school neighborhood was an important contextual determinant for the increase in the prevalence of bullying. age crosssectional cross sectional 73 characteristics disorders literacy System Index TestScreening Test Screening Andreasen criteria Kappa> Kappa (Kappa 0.80. 080 0.80 . 0 80 0.80) p <0.05 005 05 run 133 13 3 13.3% analysis PR=1.59 PR159 PR 1 59 (PR=1.59 95%CI1.032.44 95CI103244 CI 95%CI 1.03 2.44 95 03 2 44 95%CI:1.03-2.44 PR=1.79 PR179 79 (PR=1.79 95%CI1.102.93 95CI110293 1.10 2.93 10 93 95%CI:1.10-2.93 context PR=1.75 PR175 75 (PR=1.75 95%CI1.122.72. 95CI112272 1.12 2.72 12 72 95%CI:1.12-2.72) 7 08 0.8 8 <0.0 00 13.3 PR=1.5 PR15 5 (PR=1.5 CI1 032 95%CI1.032.4 95CI10324 95CI 103 1.0 244 2.4 9 4 95%CI:1.03-2.4 PR=1.7 PR17 (PR=1.7 102 95%CI1.102.9 95CI11029 110 1.1 293 2.9 95%CI:1.10-2.9 122 95%CI1.122.72 95CI11227 112 272 2.7 95%CI:1.12-2.72 0. <0. 13.

Resumo Investigar determinantes individuais e contextuais associados ao bullying em escolares de 8 a 10 anos. Foi realizado estudo transversal com 739 crianças. As crianças responderam uma pergunta sobre episódios de bullying relacionado a saúde bucal, um questionário sobre ansiedade infantil e disfunção orofacial. Os responsáveis forneceram informações sobre características sociodemográficas, distúrbios do sono e alfabetismo em saúde bucal. Examinadores treinados avaliaram as crianças para diagnóstico da cárie dentária pelo International Caries Detection and Assessment System, má oclusão por meio do Dental Aesthetic Index, disfunção orofacial pelo Nordic Orofacial Test-Screening e traumatismo dentário (Critério de Andreasen) (Kappa>0,80). As variáveis contextuais foram tipo de escola e renda mensal do bairro escolar. Estatística descritiva foi utilizada para caracterização da amostra. Modelos de regressão de Poisson multinível não ajustados e ajustados (p<0,05) foram usados. A prevalência do bullying foi 13,3%. Após análise ajustada a má oclusão (RP=1.59; IC95%:1.03-2.44) e a ansiedade (RP=1.79; IC95%:1.10-2.93) permaneceram associados ao bullying. Em relação ao contexto, a menor renda mensal do bairro da escola foi associada ao bullying (RP=1.75; IC95%:1.12-2.72). Má oclusão e ansiedade influenciaram a presença do bullying. A menor renda mensal do bairro escolar foi um determinante contextual importante para o aumento da prevalência de bullying. 1 anos 73 bucal sociodemográficas System Index TestScreening Test Screening Critério Andreasen Kappa>0,80.

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.

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.

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.

Resumo O objetivo deste estudo foi descrever e analisar o histórico de dor de dente e seus fatores associados, entre adolescentes de escolas públicas de um município do Nordeste do Brasil. Realizou-se uma pesquisa observacional, descritiva, quantitativa e transversal, através da aplicação de quatro questionários junto a 458 adolescentes. Pela análise bivariada, a prevalência de dor de dente na vida foi alta entre os adolescentes de menor idade (76,9%; p = 0,004), que visitaram o Cirurgião-Dentista alguma vez (74,8%; p = 0,001) e que relataram medo frente ao atendimento odontológico (74,9%; p = 0,006). Todavia, nos últimos 6 meses, a prevalência de dor de dente foi baixa, na qual os adolescentes do sexo masculino (77,4%; p < 0,001) e de maior idade (73,1%; p = 0,031) relataram justamente não terem sentido dor. Quando da análise multivariada, a maior prevalência de dor de dente na vida se manteve entre os adolescentes de menor idade (76,9%; p = 0,003) e que relataram medo (74,9%; p = 0,006). A prevalência de dor de dente nos últimos 6 meses se manteve baixa na análise multivariada, entre os adolescentes do sexo masculino e de maior idade. Conclui-se que a prevalência de dor de dente na vida foi maior do que nos últimos 6 meses, havendo associação significativa com os fatores: sexo, idade, visita ao Cirurgião-Dentista e sensação de medo.

Abstract The aim of this study was to describe and analyze history of toothache and associated factors among adolescent students enrolled in public schools of a city in Northeastern Brazil. An observational, descriptive, quantitative and cross-sectional study was conducted through the application of 4 questionnaires with 458 adolescents. By bivariate analysis, the prevalence of toothache in life was higher among younger adolescents (76.9%; p = 0.004), who have visited the dentist at least once (74.8%; p = 0.001) and who reported fear (74.9%; p = 0.006). The occurrence of dental pain in the last 6 months was low, where male (77.4%; p = 0,001) and older adolescents (73.1%; p = 0.031) reported no occurrence of pain. Through multivariate analysis, the highest prevalence of dental pain in life remained among younger adolescents (76.9%; p = 0.003) and who reported dental fear (74.9%; p = 0.006). The prevalence of toothache in the last 6 months remained low through multivariate analysis, among male and older adolescents. It could be concluded that the prevalence of toothache in life was higher than in the last 6 months, showing significant association with gender, age, visit to the dentist and dental fear.

Abstract: The aim of this study was to describe and evaluate access to oral health services among adolescents enrolled in public schools of Campina Grande, Paraíba, Brazil, a large-size municipality in the Northeast of Brazil. An observational, descriptive, analytical, quantitative, and cross-sectional study was carried out through a school survey, in which four validated questionnaires were applied to 438 adolescents aged 12 to 19 years. Data were processed using the SPSS statistical software version 20.0, with bivariate analysis and multivariate analysis through Poisson regression. About 90.9% of adolescents reported having visited the dentist at least once; however, when considering the last 6 months, this percentage fell to 48.4%. Adolescents used private services (50.2%) or the public service (49.8%). About 70.6% of interviewees reported dental treatment (61.1%) as the main reason for seeking the service. Through multivariate analysis, it was observed that the demand for the service was higher among female adolescents (60.5%, p <0.001); the other variables did not present statistically significant differences. In conclusion, the access to oral healthcare services reported by adolescents was good, but there is still a considerable part of this population with no access. Variables that presented significant associated with dental services were gender and toothache history, but only gender remained significant in the multivariate model.

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.

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.

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.

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 Objetivo: Relatar uma série de casos sobre o uso dos óculos audiovisuais em crianças durante o atendimento odontológico, bem como sua interferência na frequência cardíaca e percepção sobre o atendimento. Métodos: As crianças foram analisadas em três atendimentos clínicos para registro das frequências cardíacas: 1) realização da anamnese; 2) execução de um tratamento restaurador atraumático modificado (a criança usando os óculos audiovisuais) e 3) execução de um tratamento restaurador atraumático modificado sem a ferramenta de distração. O intervalo entre os atendimentos foi de até uma semana. A frequência cardíaca foi monitorada, por meio de um oxímetro de pulso e ao final da etapa dos três atendimentos, um questionário pós-tratamento foi aplicado. A amostra foi constituída por 5 crianças entre 4 e 7 anos de idade, atendidas na clínica de Odontopediatria da Universidade Estadual da Paraíba. Resultados: As frequências cardíacas individuais e as médias intermediárias do segundo atendimento, com os óculos audiovisuais, foram menores em relação ao primeiro e o terceiro; o questionário pós-tratamento revelou uma preferência no uso dos óculos audiovisuais por serem mais confortáveis, agradáveis, e por sentirem menor percepção dolorosa e ansiedade. Conclusão: A redução da frequência cardíaca com os óculos audiovisuais sugere a redução da ansiedade durante o atendimento odontológico.

ABSTRACT Objective: This study aimed to report a case series on the use of audiovisual distraction eyeglasses in children during dental care. Methods: The influence of the distraction tool on the children’s heart rate frequency and dental care experience was further investigated. The study children had their heart rate recorded during three clinical appointments and underwent the following procedures: 1) anamnesis; 2) modified atraumatic restorative treatment with the child wearing audiovisual eyeglasses; and 3) modified atraumatic restorative treatment without the use of audiovisual eyeglasses. The interval between appointments was up to one week. The heart rate was measured using a pulse oximeter, and a post-treatment questionnaire was applied after the three appointments. The sample consisted of five children aged 4 to 7 years attending the Pediatric Dental Clinics of the State University of Paraíba. Results: While wearing the audiovisual eyeglasses, the children’s individual heart rates were lower in the second dental visit as compared to the first and third ones. The post-treatment questionnaire revealed a preference for the use of audiovisual distraction eyeglasses as the children felt more comfortable, pleased, and had a reduced pain perception and anxiety. Conclusion: The heart rate decrease observed herein suggests that audiovisual eyeglasses may contribute to reducing anxiety during dental care.

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.

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.

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.
