Periodontal status among 12-year-old schoolchildren: a population-based cross-sectional study in Quito, Ecuador.

This study aimed to estimate the prevalence and extent of bleeding on probing and calculus in 12-year-old schoolchildren of Quito, Ecuador, and evaluate the associated factors. We conducted an epidemiological survey with a representative sample of 1,100 12-year-old schoolchildren from public schools in the urban area of Quito, Ecuador. We assessed the periodontal health using the Community Periodontal Index (CPI). The prevalence and extent of the periodontal condition was based on the presence of at least one site with bleeding on probing (BOP), and the presence of dental calculus was also evaluated. We used univariate and multiple multilevel Poisson regression analyses to verify the association between the independent variables and the number of sextants with BOP and calculus. The prevalence of BOP and calculus was 92% and 69.9%, respectively. The adjusted mean of the affected sextants was 4.3 and 2.2 for BOP and calculus, respectively. The mother's schooling and malocclusion were associated with the number of sextants with bleeding. The mother's schooling and dental caries experience were associated with calculus. Gingival bleeding and the presence of dental calculus are highly prevalent in 12-year-old schoolchildren from Quito. Gingival bleeding is associated with maternal education and malocclusion, and dental calculus is associated with maternal education and dental caries.

Association of children's oral health and school environment on academic performance in 12-year-old schoolchildren of Quito, Ecuador.

OBJECTIVES: The primary aim of this study was to evaluate if children's oral health and oral health-related quality of life (OHRQoL) were associated with school performance. Moreover, the study aimed to examine whether school environment factors influenced this association. METHODS: This cross-sectional study was based on a population-based sample of 998 12-year-old schoolchildren from 31 public schools in Quito, Ecuador. Trained and calibrated examiners conducted clinical exams for dental caries, dental trauma and malocclusion. Furthermore, children completed the Spanish version of the Child Perception Questionnaire (CPQ11-14 ), and their parents answered questions about socio-economic status. School coordinators provided information on the physical environment, promotion of health practices and the occurrence of negative episodes in the school. There were three outcomes: grades obtained in Spanish language and mathematics and the number of missed school days. Multilevel linear and Poisson regression models were conducted using a hierarchical approach to include the variables guided by a previously created direct acyclic graph. RESULTS: Children with dental trauma and higher CPQ11-14 scores showed lower grades and school attendance. Schoolchildren from schools with episodes of vandalism had more school days missed. CONCLUSION: The school performance of 12-year-old children is affected by dental trauma and by a worse OHRQoL, as well as a negative school environment. Therefore, supportive environments and promoting health measures in schools could overcome this worse academic performance in children with oral health problems.

Análise das urgências odontológicas durante a pandemia da covid-19 / Analysis of dental emergencies during the COVID-19 pandemic

Aim: to analyze, between 2019-2021, the quantitative changes in dental emergencies (DE) in Brazil and its regions. Materials and Methods: Data collected in the Primary Care Health Information System (SISAB) from 2019 to 2021. The DE represented by dentoalveolar abscess (DAA) and toothache (TA). 2019 was the control (non-pandemic), and 2020-21 the exposure year. Durbin-Conover's Friedman and Post-Hoc tests used a significance level of 5%. The data's organization used the percentage difference to facilitate analysis. Results: For Brazil in 2021, the percentage difference with 2019 suggests that DAA (-2.16%, p=1.0) and TA (+14.94%, p=0.064) returned to values after fall of 2020. The South region, in 2020, had no decrease in DAA (-5.48%, p=0.436) and TA (+3.7%, p<0.001) in 2020, and an increase in both in 2021 (DAA: +26.86%, p<0.001; TA: +51.06%, p<0.001). Discussion: In 2021, in Brazil, limited elective access and resumption of DAA and increase in TA suggest worsening the oral health and quality of life. The DAA and TA results in the South region do not provide plausible evidence to understand the unchanged values in 2020 and the considerable increase in 2021. Conclusion: Regardless of the pandemic, elective access still struggles to offer universal acessing, equitable, and the need of investments are essentials to prevent public services from becoming just gateways for relieving pain and suffering.

Objetivo: analisar, entre 2019-2021, as alterações quantitativas nas urgências odontológicas (UO) no Brasil e suas regiões. Materiais e Métodos: Dados coletados no Sistema de Informação em Saúde da Atenção Básica (SISAB) no período de 2019 a 2021. A representação das UO foi pelo abscesso dento-alveolar (ADA) e dor de dente (DD). O ano de 2019 foi o ano de controle (não pandêmico) e 2020-21 os de exposição. Os testes Friedman e Post-Hoc de Durbin-Conover utilizaram nível de significância de 5%. Os dados foram organizados pela diferença percentual para facilitar a análise. Resultados: Para o Brasil em 2021, a diferença percentual com 2019 sugerem que o ADA (-2,16%, p=1,0) e a DD (+14,94%, p=0,064) retomaram os valores, após a queda de 2020. A região Sul, em 2020, não teve queda em ADA (-5,48%, p=0,436) e DD (+3,7%, p<0,001) em 2020, e aumento em ambos em 2021 (ADA: +26,86%, p<0,001; DD: +51,06%, p<0,001). Discussão: Em 2021, no Brasil, o limitado acesso eletivo e a retomada da ADA e aumento da DD sugerem piora na saúde bucal e na qualidade de vida. Os resultados de ADA e DD na região Sul não apresentam evidências plausíveis para compreender a inalteração de valores em 2020 e o considerável aumento em 2021. Conclusão: Independentemente a pandemia, o acesso eletivo ainda luta para ser universal, equânime e os investimentos precisam ser retomados para evitar que os serviços públicos se tornem em apenas portas de entrada de alívio dor e sofrimento.

Does the school environment exert influence on quality of life related to traumatic dental injury in children?

The aim of this cross-sectional study was to assess whether favorable factors related to school characteristics have a positive effect on the impact of traumatic dental injury (TDI) on oral health-related quality of life (OHRQoL). An epidemiological survey of oral health was conducted with 12-year-old schoolchildren from Quito, Ecuador. Children were examined for TDI, dental caries, and malocclusion. Individual socioeconomic data were also collected. Information on the physical environment, health practices, and occurrence of negative episodes at school was collected from the school coordinators. The Child Perceptions Questionnaire 11-14 (CPQ11-14) was used to evaluate the OHRQoL (outcome variable). Multilevel Poisson regression analysis was conducted. Severe TDI was associated with higher CPQ11-14 scores, even in the multiple model adjusted for oral health conditions, sex, individual socioeconomic variables, and school-related variables. Children from schools that had an appropriate tooth-brushing environment for their students exhibited a lower impact on OHRQoL, even after adjustment for the occurrence of TDI and other variables. A favorable school environment may exert a positive effect on OHRQoL, independent of the occurrence of TDI.

Oral health coverage in the Family Health Strategy and use of dental services in adolescents in Mato Grosso do Sul, Brazil, 2019: cross-sectional study. / Cobertura de equipes de saúde bucal na Estratégia Saúde da Família e uso de serviços odontológicos em adolescentes de Mato Grosso do Sul, 2019: estudo transversal.

OBJECTIVE: To analyze the association between the coverage by oral health teams in the Family Health Strategy (FHS-OH) and the use of dental services among 12-year-old adolescents in the state of Mato Grosso do Sul, Brazil, 2019. METHODS: This is a cross-sectional study involving school-based research, which adopted the use of dental services as its outcome. Structural equation modeling was used to test the association between covariates and the outcome. RESULTS: Of the 615 participants, 74.0% used dental services in the last three years. ESF-SB (oral health coverage by family health strategy, acronym in Portuguese) ≥50% was associated with a greater use of public dental services [standardized coefficient (SC) = 0.10 -95%CI 0.01;0.18], a lower use of these services for prevention (SC = -0.07 -95%CI -0.17;0.01) and higher unhealthy food consumption (SC = 0.19 -95%CI 0.11;0.26). CONCLUSION: Higher ESF-SB coverage was associated with a lower use of dental services for prevention and higher unhealthy food consumption. Teams must organize the access to oral health service and qualify the work process.

Dental caries experience and its impact on quality of life in Latin American and Caribbean countries.

Robust epidemiological data allow for logical interventions taken in the interest of public health. Dental caries is a major public health problem driven by increased sugar consumption and various biological, behavioral, and psychosocial factors, and is known to strongly affect an individual's quality of life. This study aims to critically review epidemiological data on the prevalence of dental caries in Latin American and Caribbean countries (LACC) and its impact on the oral health-related quality of life (OHRQoL) of the population. Although the majority of national surveys did not include all age groups and several countries reported a reduction in the prevalence of cavitated carious lesions, most nations still exhibited a high burden of decayed teeth. OHRQoL evaluation was limited to children and older adults only, and was not included in any national survey. Study heterogeneity and methodological issues hindered comparison of evidence between studies and over time, and updating national level data on caries prevalence and its impact on OHRQoL should be prioritized in LACCs.

Sedentary behavior, unhealthy food consumption and dental caries in 12-year-old schoolchildren: a population-based study.

This study analyzed the association between sedentary behavior (SB), unhealthy food consumption, and dental caries amongst 12-year-old schoolchildren. An epidemiological survey was carried out in the five largest cities (> 80,000 inhabitants) of the State of Mato Grosso do Sul, Brazil. Data were collected on decayed, missing and filled teeth index (DMFT), sociodemographic characteristics, SB, unhealthy food consumption, and water fluoridation status. The analysis was based on the theoretical framework established by J Sisson. Structural equation models were performed to test the association of dental caries experience with sociodemographic, contextual, and behavioral factors. The mean DMFT index in the five cities was 1.02 (95%CI: 0.39-1.66). Higher sedentary behavior (more than 2 hours/day) [standardized coefficient (SC) = 0.21 95%CI: 0.07-0.39] and higher unhealthy food consumption (more than 4 times/week) [SC = 0.23 (0.10-0.45)] were associated with higher DMFT index than their counterparts. Also, cities with fluoridated water were associated with lower DMFT index [SC = -0.85 (-1.20--0.50)]. Families who had a per capita income above the poverty line had a direct association with unhealthy food consumption [SC = -0.24 (-0.38--0.11)]. Unhealthy food consumption mediated the association of sedentary behavior on DMFT index [SC=0.07 (0.02-0.13)]. Sensitivity analysis confirmed the findings. Sedentary behavior mediated by unhealthy food consumption had a significant association with dental caries experience. Public policies must address transdisciplinary actions to reduce sedentary behavior and unhealthy food consumption and promote water fluoridation.

Factors associated with utilisation of dental services by the elders from São Paulo, Brazil.

BACKGROUND: Population ageing in Brazil is rapid and is likely to place additional pressure over the Brazilian public health system. OBJECTIVE: This study aims to examine the factors associated with utilisation of dental services in the previous year among a representative sample of older adults from São Paulo, Brazil. METHODS: The sample included 5951 older adults who participated in the SBSP-15 study, an epidemiological survey conducted in 2015 in the State of São Paulo, Brazil. The outcome "utilisation of dental services" was defined as having visited a dentist in the previous year. Chi-square tests were employed in the bivariate analyses and Poisson regressions with robust variance in the multilevel analysis. RESULTS: Only 30.5% of the participants had their last dental appointment within the previous year. Number of teeth and dental pain presented the strongest effects on the investigated outcome. Education, income, age, ethnicity, living alone, higher Family Health Strategy coverage and the Metropolitan area were associated with having visited a dentist in the previous year. Older adults who rated their oral health as positive did not report treatment need nor prosthodontic need, presented negative oral health-related quality of life, had their last dental appointment in the public health system and sought treatment due to pain or extraction also were more likely to report the utilisation of dental services in the previous year. CONCLUSION: Regional, sociodemographic and subjective factors are associated with utilisation of dental services in the previous year among the elders from the State of São Paulo, Brazil.

Factors associated with dental caries in adolescents: a cross-sectional study, São Paulo State, Brazil, 2015. / Fatores associados à cárie dentária em adolescentes: um estudo transversal, estado de São Paulo, 2015.

OBJECTIVE: To analyze association between prevalence and severity of dental caries and demographic, socioeconomic, behavioral and oral health status in adolescents. METHODS: This was a cross-sectional study with secondary data on 5,558 adolescents examined in the São Paulo State Oral Health Survey in 2015. The zero-inflated negative binomial regression model was used, considering sample weights. Prevalence ratios (PR), ratios of mean (RM) and confidence intervals (CI) were estimated. RESULTS: Caries prevalence was 71.7%, and was higher in females (PR=1.09 - 95%CI 1.04;1.15), associated with being behind at school (PR=1.11 - 95%CI 1.03;1.18), dental calculus (PR=1.10 - 95%CI 1.01;1.20) and no access to fluoridated water (PR=1.21 - 95%CI 1.01;1.45). CONCLUSION: Identification of factors associated with dental caries can instruct the programming of health services aimed at controlling the disease.

Factors associated with the impact of oral health conditions on daily activities of adolescents, São Paulo State, 2015. / Fatores associados ao impacto das condições de saúde bucal nas atividades de vida diária de adolescentes, Estado de São Paulo, 2015.

OBJECTIVE: To assess the association between the impact of oral health on daily life and sociodemographic variables with oral parameters in adolescents living in the State of São Paulo, Brazil. METHODS: A cross-sectional study was conducted with data from 5,409 adolescents who participated in the "State Oral Health Survey of São Paulo - OH", 2015. The impact of oral health on daily life was assessed by the oral impacts on daily performances (OIDP) index, prevalence (presence or absence of impact) and severity of impact (OIDP scores). The negative binomial regression model (zeros-inflated) was used, considering the complex sampling and the sample weights. Prevalence ratio (PR), ratio of means (ROM) and confidence intervals (CI) were calculated. RESULTS: The prevalence of impact was 37.4%. After adjusting for the model, the impact was more prevalent (PR = 1.59; 95%CI 1.22 ‒ 1.81) and more severe (RR = 1.49; 95%CI 1.22 ‒ 1.81) among females. Compared to white-skin people, all remaining groups had a higher prevalence of impact. Among socioeconomic characteristics, family income higher than R$ 2,501 (RR = 0.79; 95%CI 0.64 ‒ 0.98) and household crowding (RR = 1.18; 95%CI 1.00 ‒ 1.39) were associated with the severity of impact. In the oral health conditions, untreated caries (PR = 1.46; 95%CI 1.23 ‒ 1.74) and gingival bleeding (PR = 1.35; 95%CI 1.14 ‒ 1.60) were associated with higher prevalence of impact. CONCLUSION: Females, non-whites, with untreated caries and gingival bleeding were associated with higher impact of oral health on daily life. Family income higher than R$ 2,500 and living in less crowded households were factors associated with less impact.

OBJETIVO: Verificar a associação entre impacto nas atividades de vida diária e variáveis sociodemográficas e parâmetros bucais em adolescentes no Estado de São Paulo. MÉTODOS: Estudo transversal com dados de 5.409 adolescentes que participaram da "Pesquisa Estadual de Saúde Bucal de São Paulo - SB", de 2015. O impacto nas atividades de vida diária foi avaliado pelo índice de impacto das condições de saúde bucal nas atividades de vida diária (em inglês: oral impacts on daily performances [OIDP]), pela prevalência (presença ou ausência de impacto) e pela severidade do impacto (escores do OIDP). Utilizou-se o modelo de regressão binomial negativa inflado de zeros, considerando os pesos amostrais. Foram calculados as razões de prevalências (RP), as razões de médias (RM) e os intervalos de confiança (IC). RESULTADOS: A prevalência de impacto nas atividades de vida diária foi de 37,4%. Após o ajuste, pôde-se observar que o sexo feminino permaneceu com maior prevalência (RP = 1,59; IC95% 1,36 ‒ 1,81) e severidade do impacto (RM = 1,49; IC95% 1,22 ‒ 1,81). Na comparação com brancos, os demais grupos tiveram maior prevalência de impacto. A renda familiar maior que R$ 2.501 (RM = 0,79; IC95% 0,64 ‒ 0,98) e a aglomeração domiciliar (RM = 1,18; IC95% 1,00 ‒ 1,39) foram associadas com a severidade do impacto. Nas condições de saúde bucal, verificou-se que a cárie não tratada (RP = 1,46; IC95% 1,23 ‒ 1,74) e o sangramento gengival (RP = 1,35; IC95% 1,14 ‒ 1,60) permaneceram associados com maior prevalência de impacto. CONCLUSÃO: Sexo feminino, ter cor não branca, ter cárie não tratada e sangramento gengival foram associados ao maior impacto nas atividades de vida diária. Ter renda maior que R$ 2.500 e residir em domicílios menos aglomerados associaram-se com menor impacto.

Factors associated with the need for a complete denture in one arch or both arches among the elderly population.

This study aimed to identify factors associated with the need for complete dentures in one dental arch or both, among the elderly population. The cross-sectional household study was conducted with a representative sample of elderly people (65 years or older) in the state of São Paulo, Brazil, in 2015. The dependent variable was the need for complete dentures (in one arch or both), and independent variables were socioeconomic and demographic conditions, social capital, self-perception of oral health and access to dental services. Simple and multinomial logistic regression models tested effect measures (p < 0.05). A total of 5,948 elderly people participated. Results indicated that those with greater chances of needing a complete denture in one arch were male (OR = 1.54; CI95%:1.04-2.29), with fewer household goods (OR = 2.25; CI95%:1.50-3.38), lower monthly household income: R$501-1500 (OR = 3.44; CI95%:1.27-9.35), R$1501-2500 (OR = 4.11; CI95%:1.50-11.27), R$2501-4500 (OR = 2.76; CI95%:1.10-6.95), self-reported need for a complete denture (OR = 4.75; CI95%:3.08-7.35), ≥3 years since last dental appointment (OR = 1.80; CI95%:1.06-3.05), and dissatisfaction with last dental appointment (OR = 1.80; CI95%:1.06-3.05). There were more chances of the need for complete dentures in both arches among older elders (OR = 1.44; CI95%:1.06-1.88), with lower monthly household income: R$ < 501 (OR = 4.45; CI95%:1.71-11.60), R$501-1500 (OR = 4.01; CI95%:2.14-7.51), R$1501-2500 (OR = 2.95; CI95%:1.64-5.32), < 3 years of education (OR = 1.45; CI95%:1.13-1.85), feeling unhappy (OR = 2.74; CI95%:1.35-5.57), self-reported need for a complete denture (OR = 8.48; CI95%:5.75-12.50), dissatisfaction with their mouth (OR = 2.38; CI95%:1.64-3.46), ≥3 years since last dental appointment (OR = 4.28; CI95%:2.85-6.43), and dissatisfaction with last dental appointment (OR = 4.28; CI95%:2.85-6.43). The several dimensions of the determinants of the need for a complete denture reflect the influence of both demographic and socioeconomic aspects, social capital, self-perception of oral health and access to dental services.

Influence of school environment on occurrence of traumatic dental injuries in 12 years old children.

BACKGROUND/AIM: Since children spend most of their time in school, some environmental characteristics of the schools may influence the occurrence of traumatic dental injuries (TDI). Therefore, the aim of this cross-sectional study was to assess the prevalence of TDI in 12 years old children in Quito, Ecuador, and its association with some school environmental aspects. MATERIAL AND METHODS: Six calibrated examiners evaluated 998 children from 31 public schools of Quito, to evaluate the occurrence of TDI in anterior teeth. School coordinators answered questionnaires on school physical conditions, promotion of health practices and the occurrence of negative episodes in school. The occlusion and socioeconomic status of the participants were also evaluated. Prevalence of TDI, unadjusted and adjusted by the design effect was calculated. Association between individual and contextual explanatory variables and presence of TDI were evaluated using multilevel Poisson regression analysis (P < .05). RESULTS: TDI prevalence adjusted by design effect was 20.7%. Children studying in schools with patio floor of grass and with access ramps had significantly lower prevalence of TDI than children studying in schools with patio floor of cement and with only stairs, respectively. The prevalence of TDI was also lower in children from schools that offered healthy meals or that had a proper place for oral hygiene. CONCLUSIONS: Schools with adequate physical structures and that promote health practices to their students have a lower prevalence of TDI.

Factors that influence the oral impact on daily performance of older people in Brazil: A cross-sectional population-based study.

AIM: To investigate factors that influence the oral health-related quality of life of older people (65 years and over) in Brazil. BACKGROUND: Population-based studies should be conducted to support health-planning interventions. MATERIALS AND METHODS: Data from the São Paulo State Survey on Oral Health (SBSP-2015), which consisted of 5951 individuals, were used. A theoretical-conceptual model was built based on the impact of family socio-economic characteristics, individual social-demographic features and self-perceived and clinical oral health status on the oral impact on daily performance (OIDP). Multivariate binary logistic regression analysis was conducted at 5% significance level. Statistically significant variables included within the adjusted logistic regression model entered the multiple correspondence analysis (MCA). RESULTS: Oral health impact on daily activities was observed in 34.6% of older people. Characteristics significantly related to impact on OIDP score were as follows: family income up to R$ 500 (OR = 2.73), self-perceived treatment need (OR = 1.33), self-perceived toothache (OR = 1.52), self-perception of denture replacement need (OR = 1.27), dissatisfaction (OR = 1.50) or very dissatisfied (OR = 2.57) with own oral health, partial lower denture use (OR = 1.34) and needing partial lower dentures (OR = 1.28). Increased number of people living in the same house (B = 0.05, OR = 1.06), number of bedrooms in the house (B = -0.10, OR = 0.90), age (B = -0.03, OR = 0.97) and number of teeth needing treatment (B = 0.08, OR = 1.08) contributed significantly to OIDP. CONCLUSION: Prevalence of OIDP of older people in the state of São Paulo was related to factors other than their clinical and self-perceived oral health status.

Self-perceived dental treatment need among adolescents: A hierarchical analysis.

OBJECTIVES: The aim of the present study was to analyse the factors associated with self-perceived need for dental treatment among adolescents. METHODS: A representative sample in the state of São Paulo, Brazil, comprising 5558 adolescents, was evaluated in 2015. The adolescents were selected by probabilistic sampling by conglomerates in two stages. The outcome evaluated was self-perceived treatment need measured via a validated questionnaire. Independent variables included sociodemographic factors, type, frequency and reason for last dental visit, and examination of oral conditions. Statistical analysis was based on the multiple hierarchical logistic regression model. RESULTS: Of the total sample, 3340 (62.6%) adolescents reported needing dental treatment. After fitting the model, the self-perceived need for treatment was associated with adolescents with family income of up to $1,500 BRL (OR 1.39; [95% CI = 1.20-1.60]; P < .001), who sought dental services solely for curative treatment (OR 1.58; [95% CI = 1.46-1.72]; P < .001), reported toothaches in the previous six months (OR 2.88; [95% CI = 2.53-3.28]; P < .001), were dissatisfied with the appearance of their teeth and mouth (OR 5.94; [95% CI = 5.03-7.01]; P < .001), had caries in the posterior teeth only (OR 3.04; [95% CI = 2.77-3.33]; P < .001) or had caries in the anterior teeth (OR 4.75; [95% CI = 4.05-5.56]; P < .001). CONCLUSIONS: The self-perceived need for dental treatment among Brazilian adolescents was associated with normative and subjective needs, and sociodemographic context factors. This finding provides important evidence for collective health planning.

Resumo Objetivo: Analisar a associação entre prevalência e severidade da cárie e fatores demográficos e socioeconômicos, comportamental e de condições de saúde bucal em adolescentes. Métodos: Estudo transversal com dados secundários de 5.558 adolescentes (15 a 19 anos) examinados na Pesquisa Estadual de Saúde Bucal de São Paulo em 2015. As associações foram testadas pelo modelo de regressão binomial negativa inflado de zeros, considerando-se os pesos amostrais. estimaram-se as razões de prevalência (RP), razões de média (RM) e intervalos de confiança (IC). Resultados: A prevalência de cárie foi de 71,7%, maior no gênero feminino (RP=1,09 - IC95% 1,04;1,15), associada a atraso escolar (RP=1,11 - IC95% 1,03;1,18), cálculo dentário (RP=1,10 - IC95% 1,01;1,20) e não acesso à água fluoretada (RP=1,21 - IC95% 1,01;1,45). Conclusão: A identificação dos fatores associados à cárie pode instruir a programação dos serviços de saúde dirigidos ao controle da doença.

Resumen Objetivo: Analizar la asociación entre prevalencia y magnitud de la caries y factores demográficos, socioeconómicos, conductuales y de salud bucal en adolescentes. Métodos: Estudio transversal con datos secundarios de 5.558 adolescentes (15 a 19 años) examinados en la Encuesta de Salud Oral del Estado de São Paulo en 2015. Las asociaciones se probaron mediante el modelo de regresión binomial negativa inflado de ceros, considerando los pesos de la muestra. Se estimaron las razones de prevalencia (RP), razones medias (RM) e intervalos de confianza (IC). Resultados: La prevalencia de caries fue del 71,7% y mayor en las mujeres (PR=1,09 y IC95% 1,04;1,15), asociada a atraso escolar (PR=1.11 - IC95% 1,03;1,18), cálculo dental (PR=1,10 - IC95% 1,01;1,20) y sin acceso a agua fluorada (PR=1,21 - IC95% 1,01;1,45).

Abstract Objective: To analyze association between prevalence and severity of dental caries and demographic, socioeconomic, behavioral and oral health status in adolescents. Methods: This was a cross-sectional study with secondary data on 5,558 adolescents examined in the São Paulo State Oral Health Survey in 2015. The zero-inflated negative binomial regression model was used, considering sample weights. Prevalence ratios (PR), ratios of mean (RM) and confidence intervals (CI) were estimated. Results: Caries prevalence was 71.7%, and was higher in females (PR=1.09 - 95%CI 1.04;1.15), associated with being behind at school (PR=1.11 - 95%CI 1.03;1.18), dental calculus (PR=1.10 - 95%CI 1.01;1.20) and no access to fluoridated water (PR=1.21 - 95%CI 1.01;1.45). Conclusion: Identification of factors associated with dental caries can instruct the programming of health services aimed at controlling the disease.

Tooth loss in adults: factors associated with the position and number of lost teeth.

OBJECTIVE: To evaluate the factors associated with tooth loss in adults from the position and number of teeth lost in the dental arches. METHODS: This is a cross-sectional, population-based study with adults participating in the epidemiological survey of oral health of São Paulo in 2015. The outcome of the study was tooth loss, assessed by the proposed classification, namely: I) lost up to 12 back teeth; II) lost up to 12 teeth (including front teeth); and III) lost more than 12 teeth. A four-block analysis was conducted, supported by a conceptual theoretical model adapted for tooth loss. For the multinomial logistic regression, "individuals who did not lose teeth due to caries or periodontal disease" was used as reference (p < 0.05). RESULTS: Of 6,051 adults evaluated, 25.3% (n = 1,530) were classified in category I, 32.7% (n = 1,977) in II, 9.4% (n = 568) in III, and 1.9% (n = 117) were edentulous. Lower income and schooling, the perception of need for treatment and the last appointment motivated by routine, pain or extraction were associated with tooth loss, regardless of the classification. The negative evaluation of the dental service was associated with individuals who lost up to 12 teeth, both front and back. The presence of women and periodontal pocket were associated with tooth loss of up to 12 teeth, including front, and more than 12 teeth. Caries were associated with adults who lost up to 12 teeth, including front teeth. CONCLUSION: The proposed classification allowed the identification of differences between the associated factors. Thus, the need to consider such classification in future studies is evident.

Association between social conditions and oral health in school failure.

OBJECTIVE: To evaluate the association of school failure among Brazilian adolescents with social conditions and aspects of oral health through hierarchical analysis. METHODS: A state-wide survey of 5,558 adolescents from the state of São Paulo, Brazil, inquired about the sociodemographic and social capital of participants by using a structured questionnaire. Trained and calibrated professionals performed intraoral examinations and interviews in the households. Questions about the access to dentist, reason for and frequency of using dental services, toothache episodes and impact of oral conditions on daily activities (OIDP) were applied. Oral examinations evaluated caries experience, tooth losses, periodontal problems, presence of open bite, and maxillary and mandibular overjet. School failure was estimated according to the teenagers' years of schooling. The independent variables were grouped into three blocks: sociodemographic and economic characteristics, social capital and oral health aspects. The multiple hierarchical logistic regression model was used to identify the factors associated with school failure. RESULTS: Of the total sample, information about schooling of 5,162 adolescents was obtained, of whom 29.6% presented school failure. We found that adolescents over the age of 16 years who did not declare themselves as white, female, with feelings of insecurity, unhappiness, with toothache, caries, tooth losses, affected by dentofacial and/or periodontal changes, were more likely to fail at school. CONCLUSION: Oral disorders and social factors were associated with school failure in adolescents. A successful school trajectory was a strong determinant of health, therefore actions between the educational and health sectors must be developed for adolescents, especially those with this profile.
