Impact of Oral Conditions and Subjective Factors on Academic Performance

ABSTRACT Objective: To evaluate the influence of oral health clinical and non-clinical indicators on adolescents' academic performance. Material and Methods: A longitudinal design was performed with a random sample of 1,134 12-year-old Brazilian adolescents. In 2012, the adolescents were clinically assessed by calibrated dentists and investigated about demographics, socioeconomic factors, dental service use, toothache, and verbal bullying related to oral condition via structured questionnaires. The contextual variable was obtained from the city's official database. After two years, 771 adolescents were reassessed. The outcome adolescent's academic performance (good or poor) was collected through official school's register. Multilevel logistic regression analyses were performed to assess associated factors for adolescents' academic performance. Results: Adolescents with toothache (OR 1.74; CI 95%: 1.05-2.89), who have been a victim of bullying (OR 2.23; CI 95%: 1.21-4.09), and were male (OR 1.92; CI 95%: 1.19-3.09) had a lower academic performance. On the other hand, adolescents whose mothers had higher educational levels (OR 1.79; CI 95%: 1.08-2.97) and belonged to higher-income households (OR 1.95; CI 95%: 1.18-3.23) had higher academic performance when compared to their peers. Conclusion: Adverse oral conditions, as well as subjective and socioeconomic factors, impacted on adolescents' academic performance.

Dental caries prevalence, prospects, and challenges for Latin America and Caribbean countries: a summary and final recommendations from a Regional Consensus

Abstract Dental caries can be effectively managed and prevented from developing into cavitated lesions while preserving tooth structure at all levels. However, the strong correlation between caries and socioeconomic factors may compromise the efficacy of preventive strategies. The high prevalence of persistent inequalities in dental caries in Latin American and Caribbean countries (LACC) is a matter of concern. The estimates of the burden of disease in some countries in this region are outdated or absent. This paper aims to summarize and present the final recommendations of a regional Consensus for Dental Caries Prevalence, Prospects, and Challenges for LACC. This consensus is based on four articles that were written by a team of Latin American experts, reviewed by dental associations, and presented and discussed in two consensus events. The following domains were explored: epidemiology, risk factors, prevention strategies, and management of dental caries with a focus on restorative procedures. Dental caries can manifest throughout the lifespan of an individual, making it a matter of concern for infants, children, adults, and older people alike. The prevalence rates of untreated caries in deciduous and permanent teeth are high in many parts of the world, including LACCs. Previous evidence suggests that the prevalence of dental caries in 12-year-olds is moderate to high in most Latin American countries. Moreover, the prevalence of treatment needs and dental caries in the adult and elderly population can also be regarded as high in this region. The risk/protective factors (e.g., sugar consumption, exposure to fluoride, and oral hygiene) probably operate similarly in all LACCs, although variations in the interplay of these factors in some countries and within the same country cannot be ruled out. Although salt and water fluoridation programs are implemented in many countries, there is a need for implementation of a surveillance policy. There is also room for improvement with regard to the introduction of minimal intervention techniques in practice and public health programs. Dental caries is a marker of social disadvantage, and oral health promotion programs and interventions aimed at reducing the burden of dental caries in LACCs must consider the complexity of the socioeconomic dynamics in this region. There is an urgent need to promote engagement of stakeholders, policymakers, medical personnel, universities, dental associations, community members, and industries to develop regional plans that enhance the oral health agenda for LACCs. A list of recommendations has been presented to underpin strategies aimed at reducing the prevalence and severity of dental caries and improving the quality of life of the impacted LACC population in the near future.

Associação entre o alfabetismo funcional e o reconhecimento da palavra bruxismo em adolescentes / Association between functional literacy and the recognition of the word bruxism in adolescents

Objetivo: Avaliar a associação entre alfabetismo funcional e o reconhecimento da palavra "bruxismo" entre adolescentes. Métodos: Foi um estudo transversal realizado em uma cidade de porte médio no Brasil. A amostra consistiu em 375 escolares de 12 anos e 368 de 15 a 19 anos selecionados aleatoriamente. Dois examinadores calibrados (Kappa > 0,80) aplicaram o instrumento de alfabetismo em saúde bucal validado para adolescentes o Rapid Estimate of Adult Literacy in Dentistry ­ BREALD-30 e o reconhecimento da palavra "bruxismo" foi utilizado como variável dependente, além de um questionário sobre o alfabetismo funcional (Índice de Alfabetismo Funcional ­INAF). Os pais/cuidadores responderam um questionário sociodemográfico. Foi realizada análise não-ajustada e regressão logística para amostras complexas(p < 0,05). Resultados: No modelo final, os adolescentes de 12 anos que tiveram mais chances de não reconhecer a palavra "bruxismo" foram os de escola pública (OR = 2,83; 95% IC: 1,79-4,46; p = 0,001), sem plano de saúde (OR = 2,02; 95% IC: 1,21-3,37; p = 0,007) e com menor nível de alfabetismo funcional (OR = 2,66; 95% IC: 1,66-4,26; p < 0,001). Adolescentes de 15 a 19 anos que tiveram maior chance de não reconhecer a palavra "bruxismo" foram os com menor nível de alfabetismo funcional (OR = 3,29; 95% IC: 1,93-5,60; p < 0,001), que residiam com mais pessoas em casa (OR = 2,04; 95% IC: 1,02-4,11; p = 0,040), que tinham pais/responsáveis com baixo nível de escolaridade (OR = 1,97; 95% IC: 1,15-3,36; p = 0,013) e que nunca foram ao dentista (OR = 3,08;95% IC: 1,26-7,52; p = 0,03). Conclusão:O reconhecimento do termo "bruxismo" entre os adolescentes de 12 anos foi influenciado pela presença deplano de saúde e por um maior nível de alfabetismo funcional. Na faixa etária maior, o maior nível de alfabetismo funcional, o menor número de pessoas em casa, a maior escolaridade do responsável e a ida ao dentista influenciaram no reconhecimento do termo.

Aim: To evaluate the association between functional literacy and the recognition of the word "bruxism" among adolescentes.Method: This was a cross-sectional study carried out in a mid-sized city in Brazil. The sample consisted of 375 schoolchildren, age 12, and 368, aged 15 to 19 years, selected at random. Two calibrated examiners (Kappa > 0.80) applied the oral health literacy instrument, validated for adolescents, the "Rapid Estimate of Adult Literacy in Dentistry" (BREALD-30) and the recognition of the word "bruxism" was used as a dependent variable, in addition to a questionnaire on functional literacy (Functional Literacy Index ­ INAF). Parents/caregivers answered a sociodemographic questionnaire. Unadjusted analysis and logistic regression were performed for complex samples (p < 0.05). Results: In the final model, the 12-year-old adolescents who were most likely not to recognize the word "bruxism" were those from public schools (OR = 2.83; 95% CI: 1.79-4.46; p = 0.001), without health insurance (OR = 2.02; 95% CI: 1.21-3.37; p = 0.007), and with a lower level of functional literacy (OR = 2.66; 95% CI: 1, 66-4.26; p < 0.001). Adolescents, aged 15 to 19, who had a greater chance of not recognizing the word "bruxism" were those with the lowest level of functional literacy (OR = 3.29; 95% CI: 1.93-5.60; p < 0.001), who lived with more people at home (OR = 2.04; 95% CI: 1.02-4.11; p = 0.040), who had parents/guardians with a low level of education (OR = 1.97; 95% CI: 1.15-3.36; p = 0.013). and who had never been to the dentist (OR = 3.08; 95% CI: 1.26-7.52; p = 0.03). Conclusion: The recognition of the term "bruxism" among 12-year-olds was influenced by the presence of a health plan and a higher level of functional literacy. In the older age group, the higher level of functional literacy, the smaller number of people at home, the higher level of education of the person in charge, and the individual's visit to the dentist influenced the recognition of the term.

Early Childhood Caries Experience of Children from Poor Families Living Below and Above Poverty Line

ABSTRACT Objective: To evaluate the role of poverty and its related factors on early childhood caries (ECC) experience among deprived children. Material and Methods: This population-based cross-sectional study surveyed 418 children aged one to six years enrolled in Brazilian public preschools from an area of the country known for its high social deprivation. Intraoral examination of children evaluated dental caries experience (dmft). Parents/caregivers answered a questionnaire with sociodemographic indicators. Family income was dichotomized into below or above poverty line. Data analysis used Chi-square test, Mann-Whitney test, and Multivariate Logistic Regression analysis (p<0.05). Results: Predisposing variables for an increased chance of ECC were: age group 3-4 years (OR: 4.89; 95% CI: 2.32-10.31), age group 5-6-years (OR: 5.60; 95% CI: 2.60-12.04), being part of families living below poverty line (OR: 1.88; 95% CI: 1.04-3.38) and having mothers with less than nine years of schooling (OR: 2.86; 95% CI: 2.77-7.14). Children from families living below poverty line presented higher dmft (2.9 +3.8; p=0.001) and untreated dental caries (d component) (2.7 +3.7; p=0.002). Conclusion: ECC in a poor population was influenced by indicators of social deprivation. The poorest of poor children from mothers with less years of schooling were at higher risk.

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.

Do Parents' Oral Health Literacy Levels Influence Their Response to Interventions to Improve Their Knowledge of Traumatic Dental Injuries?

Abstract Objective: To measure the influence of oral health literacy (OHL) level in the improvement of knowledge about traumatic dental injuries (TDI) after an educational intervention. Material and Methods: A total of 257 parents of children aged 0-12 years had their OHL level evaluated (BREALD-30). A leaflet with information about how to respond to TDI Emergency was developed and delivered to the parents. A questionnaire about attitudes towards TDI was administered before (TDIQ1) and after (TDIQ2) parents read the educational leaflet. The hypotheses were evaluated by non-parametric tests, correlation analysis and logistic regression. Results: The mean OHL score was 21.6. The means of correct answers in TDIQ1 were 5.5 and 5.9 (p = 0.066) and in TDIQ2 were 6.6 and 7.7 (p=0.003) between the groups with inadequate and marginal/adequate OHL, respectively. In the logistic regression, the total score of BREALD-30 and the maximum number of correct answers in TDIQ2 maintained statistical association when adjusted for schooling, gender, age of the parents, family income and the number of correct answers in the first application of the questionnaire. Conclusion: The level of OHL influenced the improvement of parents' knowledge about emergency care in cases of TDI in children from an educational intervention using a leaflet, and this intervention was more effective for parents with adequate OHL.

Má oclusão e vulnerabilidade social: estudo representativo de adolescentes de Belo Horizonte, Brasil / Malocclusion and social vulnerability: a representative study with adolescents from Belo Horizonte, Brazil

Resumo A má oclusão é um problema de saúde pública devido à alta prevalência, possibilidade de tratamento e por interferir na qualidade de vida dos indivíduos. O objetivo deste artigo é determinar a prevalência da má oclusão em adolescentes e testar sua associação com indicador de vulnerabilidade social. Foi realizado um estudo transversal representativo com 1.612 adolescentes, entre 11 e 14 anos de idade, de escolas públicas e privadas de Belo Horizonte, Brasil. Os adolescentes foram avaliados por três examinadores calibrados para o diagnóstico de má oclusão, utilizando o Índice Estético Dental. O Índice de Vulnerabilidade Social de Belo Horizonte foi utilizado para determinar o grau de vulnerabilidade social dos adolescentes. Os dados foram analisados através da regressão de Poisson com variância robusta (p < 0,05). A maioria dos adolescentes apresentou má oclusão ausente/leve (68,7%). Diagnosticou-se apinhamento dentário em 51,9% da amostra, diastema em 23,7%, mordida aberta anterior em 7,6 %. A má oclusão mostrou-se associada à vulnerabilidade social (RP = 1,25;95% IC = 1,01-1,55). O apinhamento dentário foi o tipo de má oclusão mais prevalente. Os adolescentes mais vulneráveis socialmente apresentaram piores indicadores de má oclusão.

Abstract Malocclusion is public health problem because of its high prevalence, treatment possibility, and impact on the individual's quality of life. This article aims to determining the prevalence of malocclusion in adolescents and to test its association with social vulnerability. A representative transversal study was performed with 1612 adolescents aged between 11 and 14 years old who came from public and private schools in Belo Horizonte, Brazil. The adolescents were examined by three calibrated examiners for diagnosis of malocclusion, using the Dental Aesthetic Index. The Social Vulnerability Index from Belo Horizonte was used to determine the degree of social vulnerability from adolescents. The data were analyzed using Poisson regression with robust variance (p<0,05). Most adolescents presented absence/minor malocclusion (68.7%). Dental crowding was diagnosed in 51.9% from the sample, diastema in 23.7%, anterior open bite in 7.6 %. Malocclusion was associated with social vulnerability (PR=1.25;95% CI=1.01-1.55). Dental crowding was the most prevalent type of malocclusion. The more socially vulnerable adolescents had worse indicators of malocclusion.

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.

Prevalence and factors associated with enamel defects among preschool children from a southeastern city in Brazil / Prevalência e fatores associados aos defeitos de desenvolvimento de esmalte em crianças pré-escolares de uma cidade do sudeste do Brasil

Abstract This study sought to determine the prevalence of developmental defects of enamel (DDE) among preschool children and investigate associations with sociodemographic and socioeconomic factors and weight status. A cross-sectional study was conducted with 118 children aged 3 to 5 years. Data were collected via clinical examinations and a self-administered questionnaire completed by the parents. The diagnosis of DDE was performed using the modified DDE Index. Information on socioeconomic indicators (mother's schooling, monthly income per capita), child's sex and age, and age of mother at the birth of the child were obtained by questionnaire. The children's weight status was determined based on weight-for-age at the time of the exam. Statistical analysis involved the chi-squared test and Poisson regression with robust variance. The prevalence of DDE was 50.0%. DDE were more frequent in males (p = 0.025) and children whose families were classified as being at poverty line (p = 0.040). In the Poisson model controlled for child's sex and mother's schooling, children whose families were classified as being at the poverty line had a greater prevalence rate of DDE. In conclusion, the prevalence of DDE was high in the present sample and associated with lower household income. Weight status was not associated with DDE.

Resumo Objetivou-se avaliar a prevalência de defeitos de desenvolvimento de esmalte (DDE) em pré-escolares e investigar a associação com fatores sociodemográficos e socioeconômicos e peso da criança. Foi realizado um estudo transversal com 118 crianças de três a cinco anos de idade. Os dados foram coletados por meio de exame clínico e questionário autoaplicável respondido pelos pais. Para o diagnóstico de DDE utilizou-se o Developmental Defects of Enamel Index. Informações sobre indicadores socioeconômicos (escolaridade da mãe e renda familiar per capita), gênero e idade da criança e idade da mãe ao nascimento da criança foram obtidas do questionário. O status de peso foi determinado baseando-se no peso e idade da criança no momento do exame. A análise estatística incluiu teste do qui-quadrado e regressão de Poisson. A prevalência de DDE foi 50.0%, sendo mais frequente em crianças do sexo masculino (p = 0.025) e provenientes de famílias incluídas na linha de pobreza (p = 0.040). No modelo de regressão de Poisson ajustado para gênero e escolaridade da mãe, observou-se que as crianças provenientes de famílias incluídas na linha de pobreza apresentaram maior prevalência de DDE. Conclui-se que a prevalência de DDE foi alta e associada com renda familiar per capita. O peso da criança não foi associado com DDE.

Parental perceptions of impact of oral disorders on Colombian schoolchildren´s oral health-related quality of life

There is no study assessing the impact of dental caries (DC), dental fluorosis (DF) and traumatic dental injuries (TDI) on oral healthrelated quality of life (OHRQoL) in school children from Colombia. The purpose of this study was to assess the impact of DC, DF and TDI on Colombian schoolchildren´s OHRQoL using their parents as proxies. The parents of 338 children aged 6 to 14 years from public and private schools of Cartagena, Colombia answered the ParentalCaregiver Perception Questionnaire (PCPQ) on child's OHRQoL adapted to Colombian Spanish language and a socioeconomic questionnaire. Three calibrated examiners performed the clinical assessment for DC, DF and TDI. Poisson regression associated clinical and socioeconomic conditions to the outcome. Overall, 90.24% of parents reported children's oral impact (total PCPQ score ≥ 1). The mean (standard deviation) PCPQ scores were 12.49 (14.04). The multivariate adjusted model showed that children from public schools and who have dental caries experience (RR= 1.28; p=0.04 and RR= 1.37; p= 0.018, respectively) were more likely to experience negative impact on total PCPQ scores. DC was found to be associated to parentalcaregiver perception of impact on their children's oral healthrelated quality of life, but DF and TDI were not (AU)

No existen estudios que evalúen el impacto de la caries dental (CD), la fluorosis dental (FD) y el trauma dentoalveolar (TDA) sobre la calidad de vida relacionada con la salud bucal (CVRSB) de escolares de Colombia que pertenece a países de habla hispana. El propósito de este estudio fue evaluar el impacto de la caries dental (CD), la fluorosis dental (FD) y el trauma dentoalveolar (TDA) sobre la calidad de vida relacionada con la salud bucal de escolares colombianos usando sus padres como proxies. Los padres de 338 niños y niñas de 6 a 14 años de escuelas públicas y privadas de Cartagena, Colombia, contestaron el ParentalCaregivers Perception Questionnaire (PCPQ) on child's OHRQoL adaptado al español colombiano y un cuestionario socioeconómico. Tres examinadores calibra dos realizaron la evaluación clínica para CD, FD y TDA. La regresión de Poisson asoció las condiciones clínicas y socioeconómicas al puntaje total del PCPQ y sus dominios. En general, el 90,24% de los padres reportaron el impacto oral de los niños sobre la calidad de vida (puntaje PCPQ total ≥ 1). La media (DE) del PCPQ fue de 12,49 (14,04). El modelo multivariado ajustado mostró que los niños de escuelas públicas que tenían experiencia de caries dental (RR = 1,28, p = 0,04 y RR = 1,37, p = 0,018, respectivamente) tuvieron mayor probabi lidad de experimentar un impacto negativo en las puntuaciones totales del PCPQ. La CD mostró asociación con la percepción del impacto de los padrescuidadores sobre la salud oral de sus hijos en relación con la calidad de vida. Sin embargo, FD y TDA no se encontraron asociados (AU)

Prevalence of and factors associated with enamel fracture and other traumas in Brazilian children 8-10 years old

Abstract The aim of this study was to assess the prevalence and discriminate the associated factors between enamel fractures and other trauma/trauma sequelae in 8 to 10-year-old Brazilian schoolchildren. A representative sample of 1,201 children from public and private schools were enrolled in this cross-sectional study. Questionnaires about sociodemographic characteristics were answered by parents. The outcome variable (traumatic dental injury, TDI) was multi-categorized. Independent individual variables were sex, age, number of residents in household, parents/caregivers' level of education, family income, dental caries, and overjet. Type of school was considered an independent contextual variable. Multilevel analysis, bivariate, and multivariate multinomial logistic regression models were performed. The prevalence of TDI was 14.0% (2.8% with other trauma/trauma sequelae). The multilevel analysis revealed no significant difference between the type of school and TDI. The multinomial logistic regression showed that boys (OR = 2.3; 95%CI: 1.1-4.8), older children (OR = 1.8; 95%CI: 1.1-3.0) and individuals with an overjet > 3 mm (OR = 2.5; 95%CI: 1.0-6.2) were more likely to present other trauma/trauma sequelae. Enamel fracture was not significantly associated with any variables. The prevalence of TDI in 8 to 10-year-old schoolchildren was 14% but only 2.8% of other trauma/trauma sequelae. Differences regarding the associated factors of TDI involving enamel fracture or other trauma/trauma sequelae were detected, suggesting that the different TDI classification cannot be evaluated as a single category.

Dental caries in schoolchildren: influence of inattention, hyperactivity and executive functions

Abstract Attention-deficit/hyperactivity disorder (ADHD) is characterized by inappropriate levels of hyperactivity, impulsivity, and/or inattention. Individuals with ADHD may present limitations with regard to executive functions and performing activities that involve planning and/or attention/concentration. The aim of the study was to investigate the association between dental caries and signs of ADHD in a representative sample of schoolchildren. A representative sample of 851 schoolchildren aged seven to 12 years was randomly selected from public and private schools. Data acquisition involved a clinical dental examination for cavitated permanent and deciduous teeth using the DMFT/dmft indices. Neuropsychological evaluations, including the assessment of intelligence (Raven's Colored Progressive Matrix Test) and executive functions (Corsi Tapping Blocks tests and Digit Span test) were also performed. Parents/caregivers and teachers answered the SNAP-IV Questionnaire for the investigation of signs of inattention and hyperactivity in the family and school environment. Parents/caregivers also answered questionnaires addressing socioeconomic and socio-demographic characteristics. Descriptive analysis of the variables and Poisson regression with robust variance were performed. Parental reports of signs of inattention (PR: 1.28; p < 0.05) and hyperactivity (PR: 1.15; p < 0.05) were associated with a greater occurrence of caries. A better performance on the backward order of the Corsi Tapping Blocks tests (PR: 0.94; p < 0.05) and higher level of mother's schooling were associated with a lower frequency of caries. A better performance on executive function tasks was a protective factor against dental caries, whereas children considered inattentive and/or hyperactive by their parents had a higher prevalence rate of dental caries.

Parental perceptions of impact of oral disorders on Colombian preschoolers´oral health-related quality of life / Percepción de padres del impacto de desórdenes orales de preescolares Colombianos sobre calidad de vida relacionada con la salud oral

There is no study assessing the impact of dental caries (DC), traumatic dental injuries (TDI) and dental malocclusions (DM) on the oral healthrelated quality of life (OHRQoL) of preschool children from Spanishspeaking countries in populationbased samples. The purpose of this study was to assess the impact of DC, TDI and DM, on Colombian preschool children's OHRQoL through a crosssectional study. The clinical setting included private and public preschools in Cartagena,Colombia. The sample included 643 preschool children aged 15 years and their parents, who answered the Colombian version of the Early Childhood Oral Health Impact Scale (CECOHIS) and socioeconomic questionnaire. Three calibrated examiners performed clinical assessment of severity of DC according to decayed, missing and filled primary teeth index, TDI and DM. Poisson regression associated clinical and socio economic conditions to the outcome. Overall, 48.2% of parents reported children's oral impacts (total CECOHIS score ≥1). The mean (standard deviation) CECOHIS scores were 2.20 (0.15). The multivariate adjusted model showed that children from nonnuclear families (RR=1.51; p=0.003),with low and high DC severity (RR=1.51, p=0.003; RR=1.53, p=0.009) and TDI (RR=1.56, p=0.003), were more likely to experience negative impact on total CECOHIS scores. DC and TDI have negative impact on Colombian preschool children's OHRQoL. Children from nonnuclear families have worse OHRQoL at this age, independently of the presence of oral conditions (AU)

No existen estudios que evalúen el impacto de la caries dental (CD), el trauma dentoalveolar (TDA) y las maloclusiones dentales (MD) sobre la calidad de vida relacionada con la salud bucal (CVRSB) en niños preescolares en muestras de poblaciones de países hispanohablantes. El propósito de este estudio fue evaluar el impacto de CD, TDA y MD sobre la CVRSB en niños colombianos en edad preescolar a través de un estudio transversal. Las evaluaciones clínicas se realizaron en colegios privados y públicos de Cartagena, Colombia, en una muestra de 643 niños en edad de 15 años y sus padres quienes respondieron la versión colombiana de la Escala Early Childhood Oral Health Impact Scale (CECOHIS) y un cuestionario socioeconómico. Tres examinadores calibrados realizaron la evaluación clínica de la severidad de CD acorde con el Indice ceod para dentición decidua, TDA y MD. La regresión de Poisson asoció las condiciones clínicas y socioeconómicas al puntaje total del CECOHIS y sus dominios. En general, el 48,2% de los padres reportaron impactos orales de los niños (puntuación CECOHIS total ≥1). La media (DE) del CECOHIS fué de 2,20 (0,15). El modelo multivariado ajustado mostró que los niños de familias no nucleares (RR = 1,51; p = 0,003), que tienen baja y alta severidad de CD (RR = 1,51, p = 0,003; RR = 1,53, p = 0,009) y TDA(RR = 1,56, p = 0,003) tuvieron mayor probabilidad de experimentar un impacto negativo en las puntuaciones totales de CECOHIS. La CD y la TDA tienen un impacto negativo sobre la CVRSB en niños preescolares colombianos. Los niños de familias no nucleares tienen peor CVRSB a esta edad, independientemente de la presencia de las condiciones orales (AU)

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.

Cross-cultural adaptation of the Brazilian version of the Dentine Hypersensitivity Experience Questionnaire (DHEQ-15)

Abstract The dentine hypersensitivity (DH) is able to impair the oral health related quality of life (OHRQoL). However, there isn't any specific validated questionnaire to be used in Brazil. The objective was to adapt and to validate the English version of the Dentine Hypersensitivity Experience Questionnaire (DHEQ-15) for use in Brazil. DHEQ-15 was cross-culturally adapted into the Brazilian-Portuguese language and then validated in a cross-sectional study with 100 participants recruited at a University clinic. Study sample comprised 2 groups: 100 individuals with DH, and 100 individuals without. The instrument was self-administered twice 7 to 10 days apart. The participants answered a global rating of oral health. The psychometric properties of the Brazilian version of DHEQ-15 were verified through internal consistency (Cronbach's α) and test-retest reliability (intraclass correlation coefficient - ICC), convergent (Spearman correlation) and discriminant (Mann-Whitney test) validity. The significance threshold was set at p<0.05. Sample comprised 69 men and 131 women, of mean age 30.4y. The Brazilian DHEQ-15 demonstrated very good internal consistency (α = 0.945). Test-retest reliability revealed excellent reproducibility (ICC = 0.959, p < 0.001). There was statistically significant correlation between the scores obtained on all DHEQ-15 domains and the global rating of oral health (p<0.001). Participants with DH scored significantly higher than those without DH (p<0.001). This study provides evidence supporting the cross-cultural validity of the Brazilian version of DHEQ-15 for use in Brazil.

Individuals with special needs and their families' oral health-related quality of life

Abstract To evaluate the impact of dental caries among Brazilian individuals with special health care needs (SHCN) on their families' oral health-related quality of life (OHRQoL). A cross-sectional study was carried out with a population-based sample of 227 subjects who were enrolled from the ACOLHER-PNE project conducted at the Fluminense Federal University. Parents/caregivers answered the Brazilian version of the 14-item Family Impact Scale (B-FIS) to assess the impact on family's quality of life (QoL). The main independent variable was dental caries experience, diagnosed according to the World Health Organization (WHO) criteria. The DMFT/dmft score was categorized into 0 = caries free; 1-2 = low; 3-4 = moderate; and ≥ 5 = high experience. Mother's schooling, age, sex, SHCN conditions, and socioeconomic factors were the other independent variables. QoL was measured through FIS domains and total score. Statistical analyses was performed using the Kruskal Wallis and Mann Whitney U tests and Poisson regression (p<0.05). The impact values observed in moderate and high caries experience were significantly higher than those found in subjects without caries and low level of parental emotions. Parents' years of schooling showed more impact on total score and on parental emotions. Older subjects showed significantly higher impact on total score and in all domains. The multivariate model demonstrated that families of older subjects (> 8 years old) experience a higher impact level compared to younger subjects (PR: 2.43; 95%CI: 1.80-3.29, p = 0.001). High caries experience and other socioeconomic factors were not associated with a greater negative impact on parents' QoL.

Cross-cultural adaptation and validation of the Impact of Fixed Appliances Measure questionnaire in Brazil

Abstract: The aim of this study was to translate and cross-culturally adapt the condition-specific instrument Impact of Fixed Appliances Measure (IFAM), assessing its validity and reliability for use among Brazilian children/adolescents. The IFAM was translated, back-translated, cross-culturally adapted, and pilot-tested. The Brazilian version of the IFAM (B-IFAM) was tested on 161 10-to-18-year-old children/adolescents. Internal consistency was assessed using Cronbach's alpha (α) and test-retest reliability by intraclass correlation coefficients (ICC). Construct validity was conducted using Pearson correlation among the overall and subscales of the B-IFAM. Discriminant validity was evaluated by comparisons of B-IFAM's means and SD with children's/adolescents' sex (Student t-test). Internal consistency was 0.89 for overall score and 0.55-0.86 for subscales. ICC for test-retest reliability was 0.81 for overall score and 0.55-0.78 for subscales. The overall score of the B-IFAM presented large correlation coefficients with most subscales (r = 0.52-0.74), supporting construct validity. Discriminant validity demonstrated statistically significant difference in the overall score, aesthetics, and physical impact subscales among female and male children's/adolescents' (p < 0.05). In the conclusion, the B-IFAM overall score and some subscales demonstrated adequate psychometric properties regarding reliability and validity. The study achieved a specific-condition instrument feasible for use on Brazilian children/adolescents who wear fixed orthodontic appliances.
