As crianças começam a ter contato com tecnologias digitais muito jovens, principalmente jogos educacionais (serious games). Com o aumento do uso de celulares, tablets e computadores, o uso de aplicativos voltados para promoção da saúde cresceu de maneira rápida. Quando os jogos educacionais são adequadamente desenvolvidos, os usuários aprendem o conteúdo de maneira rápida e eficiente. Há carência de estudos científicos sobre jogos educacionais no contexto da odontopediatria brasileira. Propôs-se regionalizar o jogo Barney’s healthy foods, desenvolvido internacionalmente para educação em saúde bucal de crianças, a partir das perspectivas de especialistas e usuários. Este estudo descritivo foi desenvolvido em três fases: I) discussão com especialistas a partir da versão aperfeiçoada na Jordânia; II) desenvolvimento da primeira versão brasileira do jogo; III) teste da primeira versão com crianças de 4 a 8 anos de idade e acompanhantes. Na Fase I, 12 especialistas interessados em educação em saúde, saúde bucal ou tecnologias em saúde participaram de grupo focal remoto, para avaliar a pertinência de se regionalizar o jogo para o Brasil. As transcrições das falas dos especialistas foram analisadas por análise de conteúdo que originaram categorias com as respectivas principais de indicações de alteração: hábitos alimentares – adaptação para contexto brasileiro, hábitos de higiene bucal – inclusão de fio dental e atenção à quantidade de creme dental fluoretado; faixa etária indicativa – reduzir para 4 a 8 anos; personagens – trocar o esquilo por animal da fauna brasileira; objetivo – ser menos prescritivo e promover a autonomia da criança para escolha dos alimentos. Fase II, com o código fonte do jogo original e após análise da viabilidade das modificações sugeridas pelos especialistas, a programação do jogo foi alterada e obteve-se uma versão com imagens adaptadas ao Brasil, linguagem em português-Brasileiro e conteúdo com alterações menores. Fase III, quinze crianças (idade média 6,4 anos, desvio padrão 1,3, 9 meninos) jogaram a versão brasileira uma vez, sob observação dos acompanhantes (13 mães) e da pesquisadora. A média global de acerto das tarefas do jogo foi 75,3%, e variou de 50,0% a 100%. As crianças se divertiram com o jogo, e a maioria entendeu o conteúdo e sua interface. Os acompanhantes acharam as informações relevantes e gostaram da jogabilidade para suas crianças. Com esta regionalização sistemática de um serious game, conclui-se que o Jogo de Educação em Saúde Bucal foi capaz de oferecer, a crianças brasileiras de 4 a 8 anos de idade, informações fundamentais à prevenção da cárie dentária, de forma interativa e divertida, e poderá apoiar profissionais para educação em saúde bucal. Children have experienced digital technologies since young ages, especially educational games (serious games). With the increase in smartphones, tablets, and computers, applications aimed at health promotion have multiplied. When educational games are appropriately developed, users learn content quickly and efficiently. There is a lack of scientific studies on educational games in pediatric dentistry. It was proposed to regionalize the game Barney's healthy foods, developed internationally for children's oral health education, from the perspectives of specialists and users. This descriptive study was developed in three phases: I) discussion with experts based on the improved version in Jordan; II) development of the first Brazilian version of the game; III) test of the first version with children from 4 to 8 years of age and companions. PHASE I, twelve specialists interested in health education, oral health or health technologies participated in a focus group to assess the relevance of regionalizing the game for Brazil. The transcripts of the specialists' speeches were analyzed by content analysis, which originated categories with the respective main indications of alteration: eating habits - adaptation to the Brazilian context, oral hygiene habits - inclusion of dental floss and attention to the amount of fluoride toothpaste; indicative age group – reduce to 4 to 8 years; characters – change the squirrel for an animal from the Brazilian fauna; objective – to be less prescriptive and to promote the child's autonomy to choose food. PHASE II, the original game's source code was obtained from the University of Jordan. After analyzing the feasibility of the modifications suggested by the experts, the game's programming was changed. A version was obtained with images adapted to Brazil, language in Brazilian Portuguese and content with minor changes. PHASE III, fifteen children (mean age 6.4 years, standard deviation 1.3, 9 boys) played the Brazilian version once, under the observation of the accompanying adults (13 mothers) and the researcher. The global average of correct answers in the game's tasks was 75.3% and ranged from 50.0% to 100%. Children had fun with the game, and most understood the content and its interface. The companions found the information relevant and enjoyed the gameplay for their children. We conclude that the developed Children's Oral Health Game provides relevant information on dental caries prevention after a systematic regionalization process that heard the voices of specialists and users.

In this phase, unhealthy behaviors can be acquired and buccal issues such as dental caries show high prevalence. Teenagers value esthetic aspects and the presence of caries in the previous teeth might compromise the appearance of these individuals. Besides, the buccal heath perception, especially the self-perception of the treatment need, can influence the search of odontological services. In that regard, it is important that this measure is recognized among teenagers. The objective of this study was to evaluate the associated factors to caries in previous teeth and the self-perception of the needs odontological treatment. This is a cross-sectional and analytical observational study realized in public and private schools in the city of Campina Grande, Paraiba, with a sample of 746 teenagers between 15 to 19 years old. Two researchers participated in theoretical/practical training and the calibration to the dental carie diagnosis and oral health literacy (K>0,80). The parents/ responsables answered to a socio demographic questionnaire and the teenagers answered about buccal morbid and the use of services and validated instruments about family work (Family Adaptability and Cohesion Evaluation Scales - FACES III) and about functional oral health literacy (ASB) (Brazilian Rapid Estimate of Adult Literacy in Dentistry - BREALD-30). The dental caries was evaluated following the criteria of Nyvad and Baelum (2018). The school's contextual variables were obtained from the 2017 school census of the National Institute of Studies and Research Anísio Teixeira (INEP), municipal health department and the Brazilian Institute of Geography and Statistics (IBGE). Multilevel analysis using robust negative binomial regression adjusted and unadjusted for complex samples and unadjusted and adjusted analysis using robust logistic regression for complex samples were used to assess the association between independent variables and caries in anterior tooth and self-perceived need for dental treatment (p0,80). Os pais/ responsáveis responderam um questionário sociodemográfico e os adolescentes responderam sobre morbidade bucal referida e uso de serviços e instrumentos validados sobre o funcionamento familiar (Family Adaptability and Cohesion Evaluation Scales - FACES III) e sobre o alfabetismo funcional em saúde bucal (ASB) (Brazilian Rapid Estimate of Adult Literacy in Dentistry - BREALD-30). A cárie dentária foi avaliada segundo os critérios de Nyvad e Baelum (2018). As variáveis contextuais da escola foram obtidas do censo escolar de 2017 do Instituto Nacional de Estudos e Pesquisa Anísio Teixeira (INEP), secretaria municipal de saúde e no Instituto Brasileiro de Geografia e Estatística (IBGE). Análise multinível por meio de regressão binomial negativa robusta ajustada e não-ajustada para amostras complexas e análise não ajustada e ajustada por meio da regressão logística robusta para amostras complexas foram utilizadas para avaliar a associação entre as variáveis independentes e a cárie em dente anterior e a autopercepção da necessidade de tratamento odontológico (p

Based on the concept of Health Surveillance, there is a need to expand resources and access to dental services to address the vulnerable population based on the judgments of Health Technology Assessment. The aim of this study was to identify the different concepts about the relationship of access to health services with socioeconomic issues and to evaluate the high risk of caries and untreated dental caries in schoolchildren, according to the health care model implemented, the influence of socioeconomic factors and the existence of spatial dependence. A theoretical analysis was carried out through a scoping review verifying the current scenario of the theories that describe access to oral health services related to the socioeconomic condition. In addition, two ecological studies were carried out, through descriptive and spatial analysis, of data on high-risk oral health among schoolchildren and untreated dental caries, with correlation of secondary contextual data. It was found that the theory according to Andersen that addresses self-perception and health needs is the most used. In the analysis of risk and untreated dental caries, spatial autocorrelation cannot be observed, however, a statistically significant difference was found related to distance. Thus, it is concluded that there is a tendency to expand the concept of access to health services, with socioeconomic conditions and geographical factors being strongly related to access to health services. In addition, no spatial dependence was found for any of the dependent variables, and distance proved to be a strong influence on the higher prevalence of high risk and untreated dental caries. Os determinantes em saúde geram grandes impactos sobre a saúde bucal da população, especialmente no que diz respeito à doença bucal mais prevalente, a cárie dentária. Baseada no conceito de Vigilância em Saúde, surge a necessidade de ampliação de recursos e do acesso à serviços odontológicos para contemplar a população vulnerável fundamentada nos julgamentos da Avaliação Tecnológica em Saúde. O objetivo deste estudo foi identificar os diferentes conceitos acerca da relação do acesso aos serviços de saúde com questões socioeconômicas e avaliar o alto risco da cárie e a cárie dentária não tratada em escolares, de acordo com o modelo de atenção à saúde implantado, a influência dos fatores socioeconômicos e a existência de dependência espacial. Foi realizada uma análise teórica através de uma scoping review verificando qual o cenário atual das teorias que descrevem o acesso aos serviços de saúde bucal relacionados com a condição socioeconômica. Além disso, foram realizados dois estudos ecológicos, através da análise descritiva e espacial, dos dados sobre alto risco de saúde bucal de escolares e de Cárie Dentária Não Tratada, com correlação de dados secundários contextuais. Verificou-se que a teoria segundo Andersen que aborda a autopercepção e necessidade em saúde é a mais utilizada. Na análise de risco e de Cárie Dentária Não Tratada não se pode observar autocorrelação espacial, entretanto, foi encontrada diferença estatisticamente significante relaciona à distância. Assim, conclui-se que existe uma tendência de ampliação do conceito de acesso aos serviços de saúde, sendo que condição socioeconômica e os fatores geográficos estão fortemente relacionados com o acesso aos serviços de saúde. Além disso, não foi encontrada dependência espacial para nenhuma das variáveis dependentes e a distância demonstrou ser um forte influenciador das maiores prevalências de alto risco e de Cárie Dentária Não Tratada.

This is a cross sectional and analytical observational study conducted in public and private schools in Campina Grande-PB, with a representative sample of 740 12-year-old adolescents. Two dentists participated in theoretical/practical training and calibration process for the diagnosis of dental caries and oral health literacy (K>0.80). Parents/caregivers answered a sociodemographic questionnaire and adolescents answered validated instruments about dental services utilization, family functioning (FACES-III) and functional oral health literacy (BREALD-30). Cavitated dental caries was evaluated according to Nyvad and Baelum criteria (2018) and the examiners were calibrated for clinical examinations, obtaining high inter and intra-examiner agreement. The contextual variables of the school were the educational indicators available in the Integrated Educational Information System of the National Institute of Studies and Research Anísio Teixeira (INEP) in 2017. Individual and multilevel models of Poisson regression and robust negative binomial regression for complex samples were used to evaluate the association between independent variables and dental caries and oral health literacy (p0,80). O desfecho dos dois primeiros artigos foi o número de lesões de cárie dentária cavitada enquanto o desfecho do terceiro artigo foi o alfabetismo funcional em saúde bucal. As variáveis contextuais da escola foram os indicadores educacionais disponíveis nos Sistemas Integrados de Informações Educacionais do Instituto Nacional de Estudos e Pesquisas Anísio Teixeira (INEP) em 2017.

These changes may contribute to neglected behavior in relation to oral health and little is known about the influence of psychosocial factors on dental caries experience, oral health literacy (OHL) and visit to the dentist in early adolescence. Understanding factors involved in these contexts allow the planning of oral health promotion and preventive strategies directed for this population. OBJECTIVE: The objective of this study was to evaluate the factors associated with dental caries experience, OHL and visit to the dentist in adolescents. METHODOLOGY: A cross-sectional study with a representative sample of 448 12- years-old adolescents was performed in public and private schools in the city of Cajazeiras-PB, Brazil. Parents/guardians and teachers answered the Brazilian version of the inattention and hyperactivity/impulsivity subscales (SNAP IV) for the evaluation of clinical signs of attention deficit/hyperactivity disorder (ADHD). Parents/guardians also answered to a questionnaire concerning sociodemographic data. Adolescents answered validated questionnaires about family cohesion and adaptability (FACES III), an instrument measuring OHL (BREALD-30) and a questionnaire concerning history of visit to the dentist once in the lifetime and previous experience of dental pain in the previous six months. Clinical exams for dental caries (WHO) were performed by a calibrated examiner (K>0.80). Adjusted Poisson regression analysis was performed to investigate the association between independent variables and the outcome variable of each analysis plan. The study was divided in three analysis plans, in which the outcome variables were dental caries experience, oral health literacy and visit to the dentist. RESULTS: The mean DMFT was 1.02 (SD=1.5), the mean BREALD-30 score was 20.3 (SD=4.5) and 93% of adolescents visited the dentist at some point in their life. A greater caries experience was associated with signs of ADHD (teachers' reports) (RR: 1.73; IC95%: 1.31-2.28), lower OHL (RR: 1.59; IC95%: 1.01- 2.51), lower family income (RR: 1.38; IC95%: 1.03-1.83) and greater number of residentes in the home (RR: 1.18; IC95%: 1.06-1.31). Regarding OHL, the variables associated with greater OHL were low (RR: 1.12; 95% CI: 1.04-1.22) and medium (RR: 1.11; 95% CI: 1.03-1.19) family adaptability, mothers that had more than eight years of schooling (RR: 1.07; 95% CI: 1.03-1.12) and family income higher than the Brazilian monthly minimum wage (RR: 1.08; 95% CI: 1.03- 1.12). Lower OHL was associated with low family cohesion (RR: 0.88; 95% CI: 0.82-0.95) and more signs of ADHD (teachers' reports) (RR: 0.94; 95% CI: 0.91-0.98). Regarding visit to the dentist, in the final analysis it was associated with adolescents from enmeshed (PR: 1.08; IC95%: 1.01- 1.15) and connected families(PR: 1.06; IC95%: 1.01- 1.13), attention-deficit (parent’sreport) (PR: 1.06; IC95%: 1.01-1.12) and dental pain in the previous six months (RP: 1.05; IC95%: 1.01- 1.11). CONCLUSION: Dental caries experience among adolescents was associated with signs of ADHD, OHL level and sociodemographic factors. Adolescents’ OHL was associated with family cohesion and adaptability, signs of ADHD, maternalschooling and family income. Finally, visiting the dentist was associated with family cohesion, attention-deficit according to parental report, family income and dental pain. A adolescência é um período caracterizado por mudanças nos aspectos físicos, sociais e emocionais que resultam em uma certa independência em relação aos cuidados dos pais. Essas mudanças podem contribuir para comportamentos negligentes em relação a saúde bucal e pouco se sabe sobre a influência dos fatores psicossociais na experiência de cárie dentária, no alfabetismo em saúde bucal e na ida ao dentista no início da adolescência. A compreensão dos fatores envolvidos nestes contextos permite o planejamento de estratégias de promoção e prevenção em saúde bucal voltados a esta população. OBJETIVO: O objetivo deste estudo foi avaliar os fatores associados à experiência de cárie dentária, ao alfabetismo em saúde bucal e à ida ao dentista em adolescentes. METODOLOGIA: Um estudo transversal com uma amostra representativa de 448 adolescentes de 12 anos de idade foi realizado em escolas públicas e privadas da cidade de Cajazeiras-PB, Brasil. Os pais/responsáveis e professores responderam à versão Brasileira da subescala de desatenção e hiperatividade/impulsividade (SNAP- IV) para avaliação dos sinais do transtorno do déficit de atenção e hiperatividade (TDAH). Os pais/responsáveis também responderam um questionário sobre os fatores sociodemográficos. Os adolescentes responderam questionários validados sobre a coesão e adaptabilidade familiar (FACES III), um instrumento de mensuração do alfabetismo em saúde bucal (ASB) (BREALD-30) e um questionário de histórico de ida ao dentista alguma vez na vida e experiência prévia de dor dentária nos últimos seis meses. Foi realizado o exame clínico para a cárie dentária (OMS) por uma examinadora calibrada (K>0.80). Modelos de regressão de Poisson ajustados foram realizados para avaliar a associação das variáveis independentes com a variável desfecho de cada plano de análise. O estudo foi dividido em três planos de análises, cujas variáveis desfechos foram experiência de cárie dentária, alfabetismo em saúde bucal e ida ao dentista. RESULTADOS: O valor médio do CPO-D foi de 1,02 (DP=1,5), a média do escore total do BREALD-30 foi de 20,3 (DP=4,5) e 93% dos adolescentes já visitaram o dentista alguma vez na vida. A maior experiência de cárie foi associada a sinais de TDAH (relato dos professores) (RR: 1,73; IC95%: 1,31-2,28), ao menor ASB (RR: 1,59; IC95%: 1,01-2,51), a menor renda familiar (RR: 1,38; IC95%: 1,03-1,83) e ao maior número de pessoas residentes no domicílio (RR: 1,18; IC95%: 1,06-1,31). Em relação ao ASB, as variáveis associadas ao maior ASB nos adolescentes foram a baixa (RR: 1,12; IC95%: 1,04- 1,22) e média adaptabilidade familiar (RR: 1,11; IC95%: 1,03- 1,19), as mães com mais de 8 anos de escolaridade (RR: 1,07; IC95%: 1,03-1,12) e a renda familiar de mais de um salário mínimo (RR: 1,08; IC95%: 1,03-1,12). O menor ASB foi associado a baixa coesão familiar (RR: 0,88; IC95%: 0,82-0,95) e a mais sinais de TDAH (relato dos professores) (RR: 0,94; IC95%: 0,91- 0,98). Quanto à ida ao dentista, na análise final observou-se associação com adolescentes pertencentes a famílias aglutinadas (RP: 1,08; IC95%: 1,01- 1,15) e conectadas (RP: 1,06; IC95%: 1,01- 1,13), com déficit de atenção segundo relato dos pais (RP: 1,09; IC95%: 1,04- 1,14), com renda familiar maior que um salário mínimo (RP: 1,06; IC95%: 1,01-1,12) e com dor de dente nos últimos seis meses (RP: 1,05; IC95%: 1,01- 1,11). CONCLUSÃO: A experiência de cárie dentária nos adolescentes foi associada aos sinais de TDAH, ao nível de ASB e aos fatores sociodemográficos. Já o ASB nos adolescentes foi associado à adaptabilidade e coesão familiares, aos sinais de TDAH, à escolaridade materna e à renda familiar. Por fim, a ida ao dentista foi associada à coesão familiar, ao déficit de atenção segundo relato dos pais, à renda familiar e à dor de dente.

Dental caries in childhood, due to increases of this condition in pre-school children, is a disease of high prevalence and a problem that affects the quality of life. Objective. To evaluate the prevalence and severity of dental caries in pre-school children, its relationship with the perception of the service offered in primary health care (PHC), and the impact of oral health on the quality of life of children. Methods. This is a cross-sectional study, with a representative sample of pre-school children from 3 to 5 years of the public school in Presidente Prudente 2019, and parents or guardians of children who gave their consent to participate in the research and completed the information about their child and socioeconomic condition of their family. Questionnaires were applied to parents / guardians, which addressed the impact of quality of life associated with the child's oral health (B-ECOHIS), socioeconomic status of the families (family income, family size, occupation, educational level, situation and condition of housing, and social benefit), and the questionnaire on the perception of the quality of primary care services (PCATool) used by children (Family Health Strategy-FHS, Conventional Health Care-CHC and private services). In addition, the modalities of dental coverage in schools (FHS, prevention groups-PG and full-time dentist in school-DIS) was evaluated based on the child's oral condition. The child's oral examination was performed using the ICDAS index and the prevalence and severity of dental caries was evaluated. Poisson regression test was used to determinate models of the prevalence and severity of dental caries. The data were analyzed by Chi-square, Wilcoxon, Kruskal-Wallis and Spearman correlation tests (significance level 5%). Results. The prevalence of dental caries (dmft= 0.83±2.00) had correlation with quality of life (ρ=0.42; p

Considering this, the present cross-sectional study aimed to correlate dental fear with dental caries and MIH in schoolchildren aged 8 to 10 years, in the city of Campina Grande / PB. The probabilistic sample, by clusters, was composed of 466 students of both sexes, from the urban municipal public elementary schools and the children were evaluated for dental fear, using the validated Brazilian version of the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS), and for the diagnosis of the dental caries experience, being the data obtained by three calibrated examiners, by the International Caries Detection & Assessment System (ICDAS II), obtaining inter Kappa from 0.80 to 0.90 and intra examiners from 0.71 to 0.75, and MIH, by a previously validated index, with inter Kappa from 0.61 to 0.72 and intraexaminer from 0.67 to 0.83. Descriptive analysis of the data and use of Chi-Square, U-Mann-Whitney and Spearman correlation were performed.

It is important to recognize the factors associated with dental caries in adolescents since this is a dynamic and high risk stage for behaviors that are harmful to oral health. This study aimed to evaluate the association between psychosocial and socio-demographic data, dental visit and dental caries in adolescents. A cross- sectional study was carried out with a representative sample of 769 adolescents aged 15 to 19 years from public and private schools in Campina Grande-PB, Brazil. Parents/guardians answered questionnaires about socio-demographic data. Adolescents answered the questionnaires about family cohesion and adaptability (FACES III), on the consumption of psychoactive substances (ASSIST) and about the use of oral health services. Then, adolescents responded to the Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) to provide the level of oral health literacy. Two dentists were trained through a calibration process for dental caries examination in the adolescents using Nyvad criteria (Kappa inter-examiner: 0.89-0.90 and intra-examiner: 0.88-0.90). Descriptive statistics and Poisson regression were performed (p

However, it has not yet been observed that the presence of oral complaints in individuals with risk behavior may influence their quality of life. Objective: A cross-sectional study was carried out to evaluate the impact of erosion and dental caries on the quality of life of adolescents of the female sex, aged 15 to 18 years, at risk of suffering from eating disorders, comparing them to healthy adolescents. Methods: The probabilistic sample consisted of 616 adolescents from public and private schools in Campina Grande, PB. Sociodemographic data were investigated through a questionnaire. The presence of risk behavior for eating disorders was evaluated through the Bulimic Investigatory Test of Edinburgh (BITE). The Pediatric Quality of Life Inventory^TM (PedsQL^TM) Generic Scale and Oral Health Scale questionnaire was used to measure quality of life related to general health (HRQoL) and oral health related quality of life (OHRQoL). Anthropometric measures (weight and height) were used to calculate the body mass index. To evaluate caries and dental erosion, dental examinations were performed through the CPO-D and O'Sullivan indexes, respectively. Individuals at risk for EDs were matched with those without risk by school and age (1: 1) for data analysis. Data were analyzed descriptively and inferentially using SPSS 18.0 software, using Pearson's Chi-Square, Fisher's exact test, Student's T-test and conditional logistic regression. A statistical significance level of 5% was adopted. Results: More than one-third of the adolescents (34.1%) were at risk for eating disorders. There was a statistically significant association between at -risk status for EDs and dental erosion (p 0.05), with regard to dental erosion, it was observed that the group with risk for EDs presented a mean of superior erosion to the risk-free group (p 0,05); no que se refere à erosão dentária, observou-se que o grupo com risco para TAs apresentou média de erosão superior ao grupo sem risco (p< 0,001). Adolescentes com cárie dentária obtiveram média de QVRSB menor que adolescentes sem essa condição (p

The understanding of contextual factors involved with the health-disease process allows the identification of risk areas and appropriate planning of health promotion strategies at the community level. School context is considered an important place for the intellectual development of children, as well as the development of health programs. OBJECTIVE: The purpose of this study was to evaluate the influence of individual and school context determinants on dental caries, history of dental pain and impact on the OHRQoL in five-year-old children. METHODS: A cross-sectional study based on a representative sample of 769 five-year-old children was conducted in public and private preschools in the city of Campina Grande, Brazil. Parents/caregivers answered questionnaires concerning socio-demographic data, child's oral health, sense of coherence and locus of control. Children answered the Scale of Oral Health Outcomes for five-year-old children (SOHO- 5). After the application of the questionnaires, children were examined for dental caries, traumatic dental injuries, malocclusion and dental wear according to criteria established in the literature. Dental caries was diagnosed through the International Caries Detection and Assessment System (ICDAS-II) and pufa index. The examiners were previously calibrated and obtained good inter- examiner and intra-examiner results. Variables related to social context were collected at the preschools and official municipal publications. Unadjusted and adjusted multilevel Poisson regression models were employed to investigate associations between individual and contextual characteristics with the outcome variable of each analysis plan. RESULTS: The prevalence of cavitated lesions was 58.8% and history of dental pain was reported in 23.8% of all children. The mean SOHO-5 scores were 2.37 (± 3.35). After adjusting for individual and contextual variables, the presence cavitated lesion was associated with visit to the dentist (PR = 0.73, 95% CI: 0.58-0.93), less tooth brushing frequency (

METHODS: It was a cross-sectional study with complex sample and preschool based sample with a total of 769 children of five years old from public and private preschools in Campina Grande, Brazil. Two examiners underwent a training process which involved the determination of inter- examiner and intra-examiner agreement for the diagnosis of dental trauma (K = 0.88- 0.90; K = 0.82-0.87), dental caries (K = 0.89-0.90; K = 0.87-1.00), malocclusion (K = 0.86-0.91; K = 0.94-1.00) and the consequences of untreated dental caries (K = 0.90 -1.00; K = 1.00). The Scale of Oral Health Outcomes for 5-year-old children (SOHO- 5) was used to evaluate the impact of dental trauma on the quality of life of preschoolers and the sense of Coherence (SOC) of parents/caregivers was obtained from a validated instrument. Statistical analysis varied according to each goal. Descriptive analyses were conducted, followed by logistic regression for complex samples (α = 5%) in the first analysis plan and an inductive decision tree was built through J48 Algorithm (α = 5%) for the second analysis plan of this study. RESULTS: the impact of oral problems on the OHRQoL of preschool children was 32.9% and 42.2% according to parents∕caregivers and children respectively. The presence of one (OR = 1.59; 95% CI 1.01 - 2.49) or more traumatized teeth (OR = 1.95; 95% CI 1.27 -3.00), dental pain (OR = 3.78; 95% CI 2.41-5.91) and a low educational level of parents (OR = 1.57; 95% CI 1.04 -2.38) exerted an impact on preschool OHRQoL of children according to self-report. The characteristics which remained associated with the final model for parents/caregivers‟ reports were the presence of toothache (OR = 9.86; IC 95% 16.48 - 5.90) and a lower monthly household income (OR = 1.75; 95% CI 1.11 -2.75). It was found a prevalence of 13.8% of the consequences of untreated dental caries (pufa) among the preschoolers. Parents/caregivers with a weak sense of coherence accounted for 41.7% of the sample. The factors associated with the consequences of untreated dental caries were: toothache (RP = 12.34; IC 95%: 7.87- 19.35), children from public preschools (RP = 2.38; IC 95% 3.09-1.83; p 0.001), parents/caregivers under the age of 30 years old (RP = 1.44; IC 95% 1.68-1.26; p 0.001), parents/ caregivers with more than two children (RP = 1.47; 95% CI 1.28- 1.69; p 0.001) and parents/caregivers with a weak sense of coherence (RP = 1.13; 95% CI 1.01-1.28; p < 0.001). CONCLUSION: the impact of oral health problems on preschoolers OHRQoL was high. A greater number of traumatized teeth, the presence of toothache and socioeconomic factors were associated with a worse OHRQoL in preschoolers and varied according to parents/caregivers and children reports. The prevalence of the consequences of untreated dental caries (pufa) was low and associated with social factors (type of school, age of parents/caregivers, and number of children) and a psychological factor (SOC). OBJETIVO: Avaliar o impacto do traumatismo dentário na Qualidade de Vida Relacionada à Saúde Bucal (OHRQoL) e a associação entre o Senso de Coerência (SOC) dos cuidadores, os fatores socioeconômicos e as consequências de cárie dentária não tratada (pufa) em pré-escolares. MÉTODO: Foi um estudo transversal com amostra complexa e de base pré-escolar com um total de 769 crianças de cinco anos provenientes de pré-escolas públicas e privadas de Campina Grande, Brasil. Dois examinadores foram treinados e obteve-se a concordância interexaminador e intraexaminador para o diagnóstico do traumatismo dentário (K = 0,88–0,90; K = 0,82–0,87), da cárie dentária (K = 0,89–0,90; K = 0,87–1,00), da má oclusão (K = 0,86–0,91; K = 0,94–1,00) e das consequências da cárie dentária não tratada (K= 0,90-1,00; K = 1,00). O “Scale of Oral Health Outcomes for 5-year-old children” (SOHO-5) foi utilizado para avaliar a Qualidade de Vida relacionada à saúde bucal dos pré-escolares e o Senso de Coerência (SOC) dos cuidadores foi obtido a partir de um instrumento validado. A análise estatística variou conforme cada objetivo. Análises descritivas foram conduzidas, seguidas de regressão logística para amostras complexas (α = 5%) e da construção de uma árvore de decisão indutiva (Algoritmo J48; α=5%), respectivamente para o primeiro e segundo plano de análise do estudo. RESULTADOS: O impacto dos problemas bucais na OHRQoL de pré- escolares foi de 32,9% e 42,2% segundo os pais∕cuidadores e a criança respectivamente. A presença de um (OR=1,59; CI 95% 1,01-2,49) ou mais dentes traumatizados (OR=1,95; CI 95% 1,27-3,00), dor dentária (OR=3,78; CI 95% 2,41- 5,91) e uma baixa escolaridade dos pais (OR=1,57; CI 95% 1,04-2,38) exerceu impacto na OHRQoL de pré-escolares segundo o autorrelato da criança. Para o relato dos pais∕cuidadores manteve-se associada no modelo final a presença de dor de dente (OR=9,86; CI 95% 5,90-16,48) e uma menor renda familiar mensal (OR=1,75; CI 95% 1,11-2,75). Com relação à prevalência das consequências da cárie dentária não tratada (pufa) foi de 13,8%. Os pais/cuidadores com um senso de coerência fraco corresponderam a 41,7% da amostra. Os fatores associados às consequências da cárie dentária não tratada foram: dor de dente (RP=12.34; IC 95%: 7.87-19.35), crianças de pré-escolas públicas (RP=2,38; IC 95%: 1,83-3,09; p

Phytotherapy comes up as an alternative, and the essential oil of lemon grass shows promising as an auxiliary method on chemical biofilm control. In this context, the aim of the study was to perform the chemical analysis of essential oil of Cymbopogon citratus, obtained in a company that is reference on essence and essential oil distribution, as well as to investigate the in vitro antimicrobial and antibiofilm effects of the oil, and its toxicity on human cells. For the chemical analysis, gas chromatography-mass spectrometry was used, and to identify the antimmicrobial effect, we determinate the Minimum Inhibitory Concentration (MIC) on standard strains of Streptococcus mutans UA159 and Candida albicans ATCC90029,by the microdilution method on well technic. The obtained MIC served as a reference for the antibiofilm test. To determinate the antibiofilm activity, we developed a multispecies biofilm, with Streptococcus mutans and Candida albicans, verifying the inhibitory actions of biofilm formation and the mature biofilm removal, with spectrophotometry evaluation, through a plate reader at a wavelength of 525 nm. To identify the hemolytic activity, we used blood samples from five healthy donors, subjecting the erythrocytes preparation tho the serial concentrations of the essential oil on test, with later spectrophotometry reading, at 560nm. The data was tabulated, statistically analyzed and presented as tables and charts. The main compound of the essential oil was the citral. It was evidenced the antimicrobial activity of the product at bacterial MIC of 1000 µg/mL and fungal MIC at 125µg/mL, as well as the inhibitory effect on biofilm formation on every evaluated concentrations (p

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES Incipient carious lesions manifested by white spots are frequently visualized around the orthodontic brackets. Further to possible progression of these lesions to cavities, a reduction on the bond strength of the bracket to the tooth enamel might occur due to mineral loss. Adhesive systems containing monomers that inhibits the bacteria adhesion or activity have been developed to help at caries control around of brackets. This study evaluated the caries inhibition and shear bond strength reached by addition of antibacterial monomer 2-(Methacryloyloxy)ethyl]trimethylammonium chloride (MADQUAT) to adhesive used to cement orthodontic brackets when submitted to cariogenic challenge. Sound premolars were sectioned in halves and brackets are cemented to the buccal and lingual surfaces using experimental adhesives with 0 (control), 5 or 10% of MADQUAT. Half of the samples was subjected to cariogenic challenge using a microcosm biofilm model with intermittent exposure to sucrose for 6 hours per day during 5 days. Following, the samples were embedded in resin cylinders and brackets submitted to shear loading until the de-bonding. The mode failure was analyzed under optical microscopy. The tested samples were sectioned and the internal enamel hardness measured to calculate the integrated mineral loss (ΔS). Data of bond strength and ΔS were submitted to two-way ANOVA and Tukey test, while the chi-square test was used to assess the effect of factors on failure mode (α = 0.05). The adhesive containing 10% of MADQUAT significantly reduced the demineralization around the bracket, but also reached lowest bond strength values. No effect on the bond strength and ΔS was observed by addition of 5% MADQUAT to adhesive. The cariogenic challenge did not affect the bond strength and the failure mode, which was influenced only by the adhesive. It was concluded that the MADQUAT was only effective to reduce demineralization when added to the adhesive at a concentration of 10%, whereas this concentration also reduced the bond strength. Lesões cariosas incipientes, manifestadas por meio de manchas brancas, são comumente visualizadas ao redor dos bráquetes. Além destas lesões poderem progredir para cavidades, uma redução na resistência de união do bráquete ao esmalte dental pode ocorrer devido à perda mineral. Sistemas adesivos contendo monômeros que inibem a adesão ou atividade bacteriana têm sido desenvolvidos para auxiliar no controle de cárie ao redor dos bráquetes. Este estudo avaliou a inibição de cárie e a resistência de união alcançado pela adição do monômero antibacteriano [2 - (metacriloxi) etil] trimetil cloreto de amônio (MADQUAT) ao adesivo usado para colagem de bráquetes ortodônticos quando submetidos ao desafio cariogênico. Para isto, foram utilizados trinta pré-molares hígidos, seccionados ao meio. Bráquetes foram colados nas faces vestibular e lingual usando adesivos experimentais com 0% (controle), 5% ou 10% de MADQUAT. Metade das amostras foram submetidas ao desafio cariogênico em modelo de biofilme com microcosmos, com exposição intermitente a sacarose por 6 horas por dia, durante 5 dias. Em seguida, as amostras foram embutidas em cilindros de resina e os bráquetes submetidos ao carregamento de cisalhamento até ruptura. O padrão de falha foi analisado em microscopia óptica. As amostras ensaiadas foram seccionadas ao meio e a dureza interna do esmalte mensurada para calcular a perda mineral integrada (ΔS). Os dados de resistência de união e ΔS foram submetidos à ANOVA de duas vias e teste de Tukey, enquanto queo teste Qui-quadrado foi usado para avaliar o efeito dos fatores no padrão de falha (α = 0,05). O adesivo contendo 10% de MADQUAT reduziu significativamente a desmineralização ao redor do bráquete, porém alcançou menores valores de resistência de união. Nenhum efeito na resistência de união e na ΔS foi observado com a adição de 5% de MADQUAT ao adesivo. O desafio cariogênico não afetou a resistência de união e o padrão de falha, o qual foi influenciado pelo adesivo. Concluiu-se que o MADQUAT apenas foi eficaz na redução da desmineralização quando adicionado ao adesivo para uma concentração de 10%, mas esta concentração também reduziu a resistência de união.

Therefore, a controlled cross-sectional study was carried out in order to evaluate the occurrence of erosion and dental caries in 15-18-year-old adolescent women who are at risk of suffering from eating disorders and compare them to healthy adolescents. The probabilistic sample consisted of 850 adolescents from public and private schools in Campina Grande - PB. The presence of behavioral risk for developing eating disorders was assessed using the Bulimic Investigatory Test of Edinburgh (BITE). Eating and oral hygiene habits were also investigated through a questionnaire. Anthropometric measurements (weight and height) to calculate the body mass index were measured. For evaluation of dental caries and dental erosion dental examinations were performed through the CPO-D index and the O'Sullivan index, respectively. The examiners for the diagnosis of dental caries and dental erosion remained blind to the condition of each adolescent regarding to the presence of risk behavior for disorders. The data were analyzed descriptively and inferentially using the SPSS 18.0 software. The association between the incidence of dental erosion and dental caries, and eating and oral hygiene habits was detected through a process of bivariate analysis using the Pearson's chisquared and Fisher's exact tests. A conditional logistic regression model (backward) was used to determine the association of the independent variables with risk behavior for bulimia nervosa. The prevalence of risk behaviors for eating disorders was 4.8%, with 1.5% (n = 13) of adolescents with severe risk behavior for eating disorders. Every teenager with risk was matched by school and age with four other without risk (controls). No association was found between high behavioral risk for eating disorders and dental caries (p = 0.329; OR = 2.2, 95% CI: 0.35 to 13.72) or with dental erosion (p = 0.590; OR = 2, 33, 95% CI: 0.56 to 9.70). No association was observed between eating habits and dental caries and dental erosion (p> 0.05). Logistic regression revealed that the case group was identified with significantly higher chances of having high BMI when compared to the control group (p = 0.031; OR = 5.1; 95% CI: 1.61 to 23.07). It was concluded that there was no association between risk behaviors for eating disorders and dental caries and dental erosion, but high BMI was a risk factor for developing eating disorders. Os prejuízos na saúde bucal de indivíduos portadores de distúrbios alimentares vêm sendo investigados, trazendo consigo questões discordantes quanto ao comprometimento dos dentes. Diante disso, realizou-se um estudo transversal controlado, com o objetivo de avaliar a ocorrência de erosão e cárie dentária em adolescentes mulheres, de 15 a 18 anos, em risco de estarem sofrendo de distúrbios alimentares e compará-las a adolescentes saudáveis. A amostra probabilística foi composta por 850 adolescentes de escolas da rede pública e privada de Campina Grande - PB. A presença de risco comportamental para desenvolvimento de distúrbios alimentares foi avaliada através do Bulimic Investigatory Test of Edinburgh (BITE). Hábitos alimentares e de higiene bucal também foram investigados por meio de um questionário. Foram aferidas medidas antropométricas (peso e altura) para o cálculo do índice de massa corporal. Para avaliação de cárie e erosão dentária foram realizados exames odontológicos, através dos índices CPO-D e O’Sullivan, respectivamente. Os examinadores para o diagnóstico de cárie e erosão dentária se mantiveram cegos quanto à condição de cada adolescente no que se refere à presença de comportamento de risco para os distúrbios. Os dados foram analisados de forma descritiva e inferencial através do software SPSS 18.0. A associação entre a ocorrência de erosão dentária e cárie dentária, e hábitos alimentares e de higiene bucal, foi verificada através de um processo de análise bivariada, utilizando os testes do Qui–quadrado de Pearson e Exato de Fisher. Um modelo de regressão logística condicional (backward) foi usado para determinar a associação das variáveis independentes com comportamento de risco para bulimia nervosa. A prevalência de comportamento de risco para distúrbios alimentares foi de 4,8%, com 1,5% (n=13) das adolescentes apresentando grave comportamento de risco para distúrbios alimentares. Cada adolescente com risco (caso) foi pareada por escola e idade com outras quatro sem risco (controles). Não foi observada associação entre alto risco comportamental para distúrbios alimentares e cárie dentária (p=0,329; OR= 2,2, 95% IC: 0,35-13,72) nem com erosão dentária (p = 0,590; OR = 2,33; 95% IC: 0,569,70). Não foi observada associação entre hábitos alimentares e cárie e erosão dentária (p> 0,05). A regressão logística revelou que o grupo caso foi identificado com chances significativamente maiores de possuir IMC elevado quando comparado ao grupo controle (p=0,031; OR = 5,1; IC 95%: 1,61-23,07). Concluiu-se que não houve associação entre comportamento de risco para distúrbios alimentares e cárie e erosão dentária, porém o IMC elevado foi uma condição de risco para o desenvolvimento de distúrbios alimentares.

OBJECTIVE: Evaluate the impact of dental caries, traumatic dental injury (TDI) and malocclusion on the OHRQoL of Brazilian pre-schoolers and their families. METHODS: A population-based, matched, case-control study was conducted involving 415 children aged three to five years old enrolled at public and private pre- schools in the city of Campina Grande, Paraiba, Brazil. The case group (impact on OHRQoL) and control group (no impact on OHRQoL) were matched for age, sex and monthly household income at a 1:4 ratio (83 cases and 332 controls). Impact on OHRQoL was assessed using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS). Dental caries, TDI and malocclusion were determined through clinical oral examinations performed by three previously calibrated dentists (K=0,85-0,90). Data analysis involved descriptive statistics and conditional logistic regression analysis according to the levels of analysis (p ≤ 0.05; 95% CI). RESULTS: The most frequent responses on the child section of the B-ECOHIS were “felt pain” (79.7%) and “difficulty eating” (35.0%), while the most frequent responses on the family section of the B-ECOHIS were “felt guilty” (68.6%) and “been upset” (48.2%). The following variables were significantly associated with impact on the child’s OHRQoL (cases): caries severity (OR = 4.707; 95% CI: 1.474-15.037), history of tooth pain (OR= 31.298; 95% CI: 16.046-61.048) and TDI (OR: 2.084; 95% CI: 1.042- 4.168). The following variables were significantly associated with negative impact on family OHRQoL (cases): caries severity (OR = 6.680; 95% CI: 2.731-16.349), a history of tooth pain (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 parents/caregiver’s age (OR=2.936; 95% CI: 1.077-3.478). Anterior open bite was a protective factor for OHRQoL (OR=4.050; 95% CI: 1.333-12.314). CONCLUSION: Caries severity, history of tooth pain and TDI negatively impacted the OHRQoL of pre-schoolers. Caries severity, a history of tooth pain, 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 pre-schoolers. Malocclusion did not exert an impact on the OHRQOL of the child and the family, however, anterior open bite was a protective factor for family impact. A maioria dos estudos que exploraram o impacto das desordens orais na qualidade de vida relacionada à saúde bucal (QVRSB) de pré-escolares e de suas famílias foi transversal, destacando-se a necessidade de investigações com desenhos de estudos que produzam evidências científicas mais fortes. OBJETIVO: Avaliar o impacto da cárie dentária, traumatismos dentários (TD) e má-oclusões na QVRSB de pré-escolares brasileiros e de suas famílias. MÉTODOS: Um estudo de caso-controle, emparelhado, de base populacional, foi conduzido com 415 crianças entre três a cinco anos de idade matriculadas em pré-escolas públicas e privadas do município de Campina Grande, Paraíba, Brasil. O grupo caso (com impacto na QVRSB) e o grupo controle (sem impacto na QVRSB) foram emparelhados por idade, sexo e renda mensal familiar, em uma proporção de 1:4 (83 casos e 332 controles). Impacto na QVRSB foi determinado utilizando a versão brasileira do Early Childhood Oral Health Impact Scale (B- ECOHIS). Cárie dentária, TD e má-oclusão foram determinados a partir de exames clínicos realizados por três cirurgiões dentistas previamente calibrados (K=0,85-0,90). A análise dos dados envolveu estatística descritiva e regressão logística condicional (p ≤ 0,05; 95% IC) de acordo com o plano de análise. RESULTADOS: As respostas mais frequentes na seção da criança do B-ECOHIS foram “sentiu dor” (79,7%) e “dificuldade para comer” (35,0%), enquanto que as mais frequentes na seção da família foram “sentiu-se culpado” (68,6%) e “sentiu-se chateado” (48,2%). As seguintes variáveis foram significativamente associadas ao impacto na QVRSB da criança (casos): severidade de cárie (OR = 4,707; 95% IC: 1,474-15,037), histórico de dor de dente (OR=31,298; 95% IC: 16,046-61,048) e presença de TD (OR: 2,084; 95% IC: 1,042- 4,168). As seguintes variáveis foram significativamente associadas ao impacto na QVRSB da família da criança (casos): severidade de cárie (OR = 6,680; 95% IC: 2,731- 16,349), histórico de dor de dente (OR= 2,666; 95% IC: 1,492-4,765), percepção ruim da saúde bucal da criança (OR: 1,973; 95% IC: 1,072-3,634) e idade dos pais/responsáveis (OR=2,936; 95% IC: 1,077-3,478). Mordida aberta anterior foi um fator de proteção para QVRSB das famílias (OR=4,050; 95% IC: 1,333-12,314). CONCLUSÃO: Severidade de cárie, histórico de dor de dente e TD impactaram negativamente a QVRSB dos pré-escolares. Severidade de cárie, histórico de dor de dente, percepção ruim da saúde bucal da criança e pais/responsáveis mais jovens foram associados a impactos na QRVSB das famílias dos pré-escolares. Má-oclusões não impactaram negativamente a QRVSB da criança e de sua família, contudo a presença de mordida aberta anterior foi um fator de proteção para impacto familiar.

METHODS: A cross-sectional study was carried out with 837 preschool children enrolled in public and private institutions of Campina Grande-PB, Brazil. A pilot study was previously conducted with 40 preschoolers, to ascertain the methodology used. The Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) was applied to determine the impact of dental caries and oral disorders on quality of life related to oral health (OHRQoL) of preschool children and their parents/guardians. The items “financial impact” and “taken time off work” (absenteeism) were the dependent variables. Parents/caregivers also completed a questionnaire on sociodemographic information (child’s sex, child’s age, parent’s/caregiver’s age, maternal education and family income), toothache history, perception of children’s general health and oral health. Clinical examinations were performed in children for three calibrated dentists (K: 0,85 to 0,90). As diagnostic criteria, it was used the International Dental Caries Detection and Assessment System (ICDAS-II) and the criteria for diagnosis proposed by Andreasen et al. (2007). Descriptive and analytical statistics were performed, followed by logistic regression for complex samples (α = 5%). RESULTS: The frequency of absenteeism at work by parents/guardians due to oral health problems of their children was 9.2%. The factors associated with absenteeism were: low maternal education (OR = 2.306; 95% CI: 1.307- 4.068), toothache history (OR = 6.329; 95% CI: 3.178-12.607), and TDI types of avulsion/dislocation (OR = 7.927; 95% CI: 1.489-42.205). The frequency of financial impact due to oral health problems of preschool children was 7.7%. The following variables were associated with the financial impact: parental perception of oral health as bad (OR = 2.025; 95% CI: 1.016-4.034) and interaction between dental pain history and tooth decay (OR = 22.587; 95% CI: 4.838-105.448). CONCLUSION: Absenteeism at work by parents/guardians was influenced by maternal education, toothache history and dental trauma type avulsion/dislocation in preschoolers. The occurrence of financial impact on the family has been affected by the bad perception of parents about the oral health of children and interaction between dental pain history and tooth decay. OBJETIVO: Determinar o impacto da cárie dentária e do traumatismo dentário de pré- escolares de três a cinco anos sobre as finanças e trabalho dos seus pais/responsáveis. MÉTODO: Um estudo transversal foi realizado com 837 pré-escolares matriculados em instituições públicas e particulares de Campina Grande-PB, Brasil. Um estudo piloto foi conduzido previamente com 40 pré-escolares, para averiguar a metodologia utilizada. A versão brasileira do Early Childhood Oral Health Impact Scale (B- ECOHIS) foi aplicada para determinar o impacto das alterações bucais na qualidade de vida relacionada à saúde bucal (QVRSB) dos pré-escolares e de seus pais/responsáveis. Os itens “impacto financeiro” e “tempo de trabalho perdido” (absenteísmo) foram as variáveis dependentes utilizadas nesta pesquisa. Os pais/responsáveis também responderam a um questionário sobre informações sóciodemográficas (sexo da criança, idade da criança, idade do pai/responsável, escolaridade materna e renda familiar), histórico de dor de dente, percepção de saúde geral e saúde bucal de seus filhos. Os exames clínicos nas crianças foram realizados por três cirurgiões-dentistas previamente calibrados (K:0,85-0,90). Foram utilizados como critérios de diagnóstico, o International Dental Caries Detection and Assessment System (ICDAS-II) e o critério de diagnóstico de traumatismo dentário proposto por Andreasen et al. (2007). Foi realizada estatística descritiva e analítica, seguida de regressão logística para amostras complexas (α= 5%). RESULTADOS: A frequência de absenteísmo no trabalho pelos pais/responsáveis devido a problemas de saúde bucal de suas crianças foi de 9.2%. Os fatores associados com o absenteísmo foram: baixa escolaridade materna (OR=2.306; 95% IC: 1.307-4.068), histórico de dor de dente (OR= 6.329; 95% IC: 3.178-12.607) e trauma dentário dos tipos avulsão/luxação (OR= 7.927; 95% IC: 1.489-42.205). Já a frequência de impacto financeiro devido a problemas de saúde bucal de pré-escolares foi de 7.7%. As seguintes variáveis foram associadas ao impacto financeiro: percepção parental sobre a saúde bucal como sendo ruim (OR=2.025; 95% IC: 1.016-4.034) e interação entre histórico de dor de dente e cáries dentárias (OR= 22.587; 95% IC: 4.838-105.448). CONCLUSÃO: O absenteísmo no trabalho pelos pais/responsáveis foi influenciado pela escolaridade materna, histórico de dor de dente e traumatismo dentário do tipo avulsão/luxação nos pré-escolares. A ocorrência de impacto financeiro para a família foi afetada pela percepção ruim dos pais sobre a saúde bucal dos filhos e interação entre histórico de dor de dente e cáries dentárias.

The aim of this study was to determine the prevalence and factors associated with dental caries, periodontal changes and dental trauma in children and adolescents with cerebral palsy. A cross-sectional study was carried out with a non- probabilistic sample of 80 patients aged 2-18 years treated in a rehabilitative institution in northeastern Brazil. Clinical data were obtained from medical records, while caregivers answered a socioeconomic questionnaire. Oral examinations were performed by calibrated investigator (K = 0,66-1,00), with record of DMFT, dmft, Gingival Bleeding Index (GBI), Community Periodontal Index (CPI), Dental Aesthetic Index, malocclusion and Dental Trauma. Possible Associations were verified by bivariate and multivariate Poisson regression analysis (α = 0,05). The results revealed prevalence of dental caries of 59,3%, with average DMFT and dmft of 1,71+2,42 and 2,22+3,23, respectively. In periodontal evaluation, 89,9% showed changes. The average GBI was 22,44% and the prevalence of gingival bleeding, calculus, shallow and deep periodontal pockets, were 94,73%, 79,62%, 12,90% and 3,22%, respectively. The prevalence of dental trauma was 36,3%, with enamel fracture being the most common dental trauma (89,1%). In multivariate analyses, schooling of less than eight years of caregiver (OR = 1,43; 95% CI = 1,09-1,89) was associated with caries experience. Periodontal changes were associated with female gender (OR = 0,82; 95% CI = 0,69-0,97), schooling less than eight years of caregiver (OR = 1,15; 95% CI = 1,03-1,29), poor oral perception (OR = 0,89; 95 CI% = 0,80-0,98), severe communication impairment (OR = 0,87; 95% CI = 0,76-0,99) and athedoid CP (OR = 0,85; 95% CI = 0,75-0,97). However, dental trauma was not associated with socioeconomic, oral and systemic characteristics (p> 0,05). It was concluded that individuals with CP showed high prevalence of dental caries, periodontal changes and dental trauma and except for dental trauma, associations with socioeconomic and systemic characteristics. A avaliação da frequência e fatores associados aos agravos bucais, em populações pediátricas com Paralisia Cerebral, é necessária para o planejamento e execução de programas de promoção em saúde. O objetivo desse trabalho foi determinar a prevalência e fatores associados à cárie dentária, alterações periodontais e traumatismo dentário em crianças e adolescentes com Paralisia Cerebral. Realizou-se um estudo transversal com amostra não probabilística de 80 pacientes de 2 a 18 anos atendidos em uma Instituição reabilitadora na região nordeste do Brasil. Os dados clínicos foram obtidos do prontuário, enquanto os cuidadores responderam a um questionário socioeconômico. Os exames orais foram feitos, por pesquisador calibrado (K=0,66- 1,00), com registro do CPO-D, ceo-d, Índice de Sangramento Gengival (ISG), Índice Periodontal Comunitário (IPC), Índice de Estética Dental, má oclusão e de Traumatismo Dentário. Possíveis associações foram verificadas com as análises bivariada e multivariada de Regressão de Poisson (α=0,05). Os resultados revelaram uma prevalência da cárie dentária de 59,3%, com CPOD e ceo-d médio de 1,71+2,42 e 2,22+3,23, respectivamente. Na avaliação periodontal, 89,9% apresentaram alterações. O ISG médio foi de 22,44% e as prevalências de sangramento gengival, cálculo, bolsa rasa e profunda, foram de 94,73%, 79,62%, 12,90% e 3,22%, respectivamente. A prevalência do traumatismo dentário foi 36,3%, sendo a fratura de esmalte o trauma dentário mais comum (89,1%). Nas análises multivariadas, escolaridade inferior a oito anos do cuidador (RP=1,43; IC95%=1,09-1,89) teve associação com a experiência de cárie dentária. As alterações periodontais apresentaram associação com sexo feminino (RP=0,82; IC95%=0,69-0,97), escolaridade inferior a oito anos do cuidador (RP=1,15; IC95%=1,03-1,29), percepção bucal ruim (RP=0,89; IC95%=0,80-0,98), habilidade de comunicação grave (RP=0,87; IC95%=0,76-0,99) e tipo atetóide de PC (RP=0,85; IC95%=0,75-0,97). No entanto, o traumatismo dentário não apresentou associação com as características socioeconômicas, bucais e sistêmicas avaliadas (p>0,05). Conclui-se que os indivíduos com PC apresentaram alta prevalência de cárie dentária, alterações periodontais e traumatismo dentário, demonstrando, exceto pelo traumatismo dentário, associação com suas características socioeconômicas e sistêmicas.

Sickle cell anemia (HbSS) is a mendelian genetic disorder caused by a point mutation (A/T) on hemoglobin’s beta globin gene, originating an abnormal hemoglobin called hemoglobin S (HbS). People with HbSS have more susceptibility to develop infections, inflammation, ischemia, episodes of pain and tissue necrosis, as well as changes in the stomatognathic system and its associated structures. The aim of this study was to evaluating socioeconomic, clinical, genetic and caries in children with HbSS in the State of Sergipe. This cross-sectional case-control study involved 210 volunteers, 70 HbSS composing the study group (SG) and 140 composing the group of control (CG). The SG was paired with CG on age and gender. Data collection included interviews with the parent/guardian, verification of medical records and clinical examination. Statistical analyzes were performed using SPSS version 20, considering a confidence interval of 95% (p

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES The bond strength of indirect restorations luted with self-adhesive resin cements to caries affected dentin has been poorly studied, despite this substrate be frequently found in cavity preparations. To standardize this substrate type, in vitro protocols of caries induction under controlled conditions are commonly used for bond strength tests. The aim of this study was to evaluate the bond strength of self-adhesive resin cements RelyX U200 and BisCem, and regular resin cement RelyX ARC to caries-affected dentin induced artificially. A microcosm biofilm from saliva of a donator was inoculated over dentin samples from caries-free human third molars and cultivated under anaerobic conditions for 14 days. It was used a model with intermittent availability of 1% sucrose for 4 hours per day. Cylinders of each resin cement were build-up on sound and caries-affected dentin surface (n=24). The cylinders were submitted to microshear testing after 24 hours. Vicker’s hardness (VH) and elastic modulus (E) were measured in both substrates until the depth of 200 μm. Data of bond strength were submitted to two-way ANOVA followed by Student-Newman-Keuls (SNK) multiple comparisons test; and the failure mode was evaluated by Fisher’s Exact and Chi-Square tests (P < 0.05). Data of VH and E were submitted to split-plot ANOVA and SNK’s test (P < 0.05). Caries-affected dentin presented the lower values of VH and E than sound dentin until the depth of 50 and 100 μm, respectively. The bond strength of all cements was lower on caries-affected dentin than sound dentin. Bond strength of RelyX U200 was similar to RelyX ARC and higher than BisCem, independently of substrate. In conclusion, the resin cements evaluated showed lowest bond strength values to caries-affected dentin, which presented lower mechanical properties than sound dentin near to surface where the adhesive procedures were performed. A resistência de união de restaurações indiretas cimentadas com cimentos resinosos autoadesivos na dentina afetada por cárie tem sido pouco estudada, apesar de esta ser frequentemente encontrada em preparos cavitários. Para padronizar este tipo de substrato, protocolos in vitro de indução de cárie sob condições controladas são comumente empregados para testes de resistência de união. O objetivo deste estudo foi avaliar a resistência de união dos cimentos resinosos autoadesivos RelyX U200 e BisCem, e do cimento resinoso convencional RelyX ARC, na dentina afetada por cárie induzida artificialmente. Biofilmes de microcosmos originados da saliva de um doador, foram cultivados em condições de anaerobiose por 14 dias e formados sobre as amostras de dentina de terceiros molares humanos livres de cárie. Utilizou-se o regime de alimentação intermitente de sacarose à 1% em meio de cultura por 4 horas diárias. Cilindros de cada cimento resinoso foram confeccionados nas superfícies de dentina afetada por cárie ou hígida (n= 24). Os cilindros foram submetidos ao ensaio de microcisalhamento após 24 horas. A dureza Vickers (VHN) e módulo de elasticidade (E) foram medidos nos dois substratos avaliados até a profundidade 200 μm. Os dados de cisalhamento foram submetidos à Análise de Variância (ANOVA) de dois fatores, seguido pelo teste de comparações múltiplas de Student-Newman-Keuls (SNK), e o padrão de falha foi avaliado pelo teste Exato de Fisher e Qui-quadrado (P < 0,05). Os dados de VHN e E foram submetidos a ANOVA de parcela subdivida e teste de SNK (P < 0,05). A dentina afetada por cárie apresentou menores valores de VHN e E do que a dentina hígida até as profundidades de 50 e 100 μm, respectivamente. A resistência de união de todos os cimentos foi menor na dentina afetada por cárie que na dentina hígida. A resistência de união do RelyX U200 foi similar à do Relyx ARC e maior que a do BisCem, independente do substrato. Concluiu-se que os cimentos resinosos avaliados mostraram uma menor resistência de união na dentina afetada por cárie, que apresentou menores propriedades mecânicas que a normal próximo à superfície onde foi realizado os procedimentos de união.

O presente estudo tem como objetivo avaliar o efeito do gás ozônio na dentina exposta a biofilme de Streptococcus mutans por meio da avaliação do conteúdo mineral (Log Ca/P) do substrato dental utilizando a ferramenta da Espectroscopia de Energia Dispersiva-EDS. Cinco terceiros molares foram seccionados em quatro fatias de dentina e dividas em quatro grupos: Grupo I, Controle (sem tratamento); Grupo II, terapia com ozônio; Grupo III, desenvolvimento de biofilme; e Grupo IV, terapia com ozônio seguida de desenvolvimento do biofilme. O conteúdo mineral (Log Ca/P) foi avaliado por meio da EDS. Os dados obtidos foram tabulados e analisados por meio da Análise de variância one-way para medidas repetidas e do Teste de Tukey (P

Como a água em Manaus não é fluoretada, o método mais comum de obtenção de flúor é através dos dentifrícios, os quais caracterizam-se como veículos de baixa concentração e alta freqüência. Porém, para que um dentifrício possa exercer seu efeito anticárie, é necessário que tenha uma concentração mínima adequada e estar solúvel. Sendo assim, este trabalho tem como objetivo avaliar a concentração de flúor presente em ovos dentifrícios comercializados na cidade de Manaus. Serão adquiridos do comércio da cidade de Manaus cinco dentifrícios fluoretados, saber: Even r® ; Colgate Shrek®, Colgate Total 12®, Clgate Max White®; Crest® (como padrão ouro). As amostras serão feitas em triplicatas e as concentrações de flúor total, flúor solúvel total e flúor iônico obtidas, em duplicata. As amostras serão analisadas utilizando um analisador de íons, ORION 720-A, e um eletrodo específico, ORION 96-09. O analisador de íons e eletrodo serão previamente calibrados com soluções padrões, contendo de 2,0 a 32 µg F/mL. Os resultados serão avaliados por estatística descritiva.
