Prolonged use of old dentures: A qualitative study with Brazilian older adults.

OBJECTIVE: To explore older adults' perceptions, motivations and reasons for using and not replacing old and worn complete dentures over prolonged periods. MATERIALS AND METHODS: In-depth, semi-structured interviews were conducted with Brazilian edentulous older adults who were wearing complete dentures which were at least 20 years old. A purposive sampling method was used to recruit participants from an existing waiting list of those referred to a hospital clinic for new dentures. The interviews were video-recorded, transcribed verbatim and analysed using thematic analysis. RESULTS: Sixty-two individuals were assessed and nine were included in the study, aged from 61 to 77 years (mean = 65.4), with seven (77.8%) of them women. The reported time using their current dentures ranged from 22 to 45 years (mean = 28). Content analysis revealed three main themes: the perception of the current dentures' condition after prolonged use; reasons for the prolonged use and non-replacement; and unsuccessful attempts to replace the dentures. Overall, participants acknowledged the poor condition of their dentures and did recognise the need for replacement. Several factors had prompted them to delay or temporarily forego replacement, with financial constraints being the main barrier. Some reported failed attempts to replace the dentures in the past years or months; however, challenging adaptation to the new prostheses led to them reverting back to their old dentures as a fallback solution. CONCLUSION: Factors influencing prolonged denture use in older adults include a complex interplay of financial aspects, treatment awareness, access and personal factors. Dental professionals can play a pivotal role in promoting timely denture adjustment or replacement by addressing these factors through patient education and personalised care.

Implementação do Programa Saúde na Escola: relação com aspectos da saúde bucal dos estudantes / Implementation of the School Health Program: relationship with aspects of students' oral health

RESUMO O estudo objetivou investigar a associação entre a implementação do Programa Saúde na Escola (PSE) e aspectos relacionados com a saúde bucal de adolescentes escolares que frequentam escolas públicas no Brasil. Foi realizado estudo transversal exploratório utilizando dados da Pesquisa Nacional de Saúde Escolar (PeNSE) 2015 em uma amostra de 81.154 estudantes de 13 a 15 anos frequentando escolas públicas das capitais, Distrito Federal e interior. Os dados foram obtidos por meio de questionários respondidos pelos alunos e responsáveis pelas escolas. Foi realizada análise bivariada de associação entre a variável 'implementação das ações do PSE pela escola' (Sim/Não) e aspectos relativos à saúde bucal dos estudantes. Em comparação com escolas sem implementação do PSE, as que haviam implementado o Programa apresentavam melhores indicadores de comportamento (consumo de alimentos com açúcar adicionado, cigarro e álcool); venda de alimentos saudáveis ou com açúcar adicionado; existência de grupo/comitê de saúde, ações do Programa Mais Educação e ações em conjunto com a Unidade Básica de Saúde (p<0,05). Concluiu-se que houve associação entre a implementação do PSE e aspectos mais favoráveis relacionados com a saúde bucal, referentes a alimentação, uso de cigarro e álcool entre os escolares, e ações de saúde e educação nas escolas.

ABSTRACT This study aimed to investigate the association between the School Health Program (PSE) implementation and aspects related to the oral health of adolescent students attending public schools in Brazil. An exploratory cross-sectional study was conducted using data from the 2015 National School Health Survey (PeNSE) in a sample of 81,154 students aged 13 to 15 in the capitals, Federal District, and inland cities. Data were retrieved from questionnaires answered by students and those responsible for the schools. We performed a bivariate analysis of the association between the variable 'implementation of PSE actions by the school' (Yes/No) and aspects related to the students' oral health. Compared to schools without PSE implementation, those that had implemented the Program had better behavioral indicators (consumption of sugar-added foods, cigarettes, and alcohol); selling healthy or sugar-added foods; availability of a health group/committee, and actions of the More Education Program and with Primary Health Care Units (p<0.05). We concluded that there was an association between the implementation of the PSE and more favorable aspects related to oral health regarding the students' diet, tobacco use, and alcohol consumption, and school health and education actions.

Educational quality and oral health promotion in Brazilian schools: a multilevel analysis of national data.

The aim of this study was to investigate whether educational quality is associated with schools' potential support for oral health promotion in Brazil, using a multilevel model. An ecological study was carried out using data from 940 public schools (school level) from the 27 Brazilian state capitals (city-level). The explanatory variable was educational quality, measured by the Basic Education Development Index (IDEB) for each city, and the four dependent variables referred to the Oral Health Promotion School Environment (OHPSE) indicator and its dimensions: Dimension 1 (In-school aspects), Dimension 2 (Aspects of the school surroundings), and Dimension 3 (Prohibitive policies at school). The OHPSE was developed using categorical principal components analysis (CATPCA) of data from the 2015 National Adolescent School-Based Health Survey (PeNSE). Covariates were human development index and oral health care coverage of cities. Multilevel Poisson regression models with robust variance were undertaken (p < 0.05). Bivariate associations were found between the IDEB and each Total OHPSE and OHPSE-Dimension 1 (In-school aspects: sale of foods with added sugar and health promotion actions/programs). After adjustment, IDEB (PR: 1.38, 95%CI: 1.01-1.90; p = 0.045) and oral health care coverage (PR: 1.01; 95%CI: 1.00-1.02; p = 0.001) remained associated with the OHPSE Dimension 1. It was concluded that educational quality measured by the IDEB was associated with schools' potential support for oral health promotion regarding the sale of foods with added sugar and health promotion actions/programs in schools.

Single versus two-implant mandibular overdentures using early-loaded titanium-zirconium implants with hydrophilic surface and ball attachments: 1-year randomized clinical trial.

OBJECTIVE: This randomized clinical trial aimed to compare the outcomes of the mandibular overdenture retained by one (1-IOD) or two (2-IOD) implants. MATERIALS AND METHODS: Participants received new complete dentures, were assessed at baseline and randomly assigned to groups. Early loaded single midline implant (1-IOD) or two implants in the canine regions bilaterally (2-IOD). Ball attachments were used for overdenture retention. Post-treatment outcomes (6- and 12-month follow-ups) included patient satisfaction, oral health-related quality of life measures, and chewing function. Data analysis included within- and between-group comparisons, and Generalized Estimating Equations. Both superiority and non-inferiority hypotheses were tested. RESULTS: Forty-seven participants were included (1-IOD = 23; 2-IOD = 24). Significant improvements in OHIP-Edent were observed after insertion of new dentures and at the 1-year follow-up compared with baseline. No differences were found between the 1- and 2-IOD groups for the OHIP-Edent and QoLFAST scores. Patient satisfaction with the mandibular denture improved significantly from baseline to the 6-month follow-up and remained unaltered until 1 year, with no differences between groups. The magnitudes of treatment effect sizes were moderate to large for patient-reported outcomes. Progressive improvement in chewing function occurred in both groups. Non-inferiority testing based on a 15% non-inferiority margin showed inconclusive results for patient-reported outcomes, whilst chewing function in the 1-IOD group was concluded to be not inferior to the 2-IOD group. CONCLUSIONS: Results support the use of both 1- and 2-IOD. The 1-IOD was also an acceptable alternative to the 2-IOD as a secondary option for the treatment of the edentulous mandible.

Can the school environment influence oral health-related behaviours? A multilevel analysis of the Brazilian National Adolescent School-Based Health Survey 2015.

OBJECTIVE: To investigate the association between the potential support of schools for oral health promotion and a set of oral health-related behaviours among adolescent students in Brazilian state capitals. METHODS: A cross-sectional study using individual and school environment data from the 2015 Brazilian National Adolescent School-Based Health Survey (PeNSE) was conducted. The sample consisted of 51 192 students from 1339 public and private schools in the 27 Brazilian State Capitals, aged 11-19 years old. The outcomes were six oral health-related behaviours: dental visits; toothbrushing frequency; soft drink and sweets consumption; smoking and alcohol consumption. The explanatory variable was the Oral Health Promotion School Environment index (OHPSE). Covariates were the adolescents' sociodemographic characteristics and organizational aspects of the schools. A two-level multilevel mixed-effects Poisson regression analysis with fixed slopes and random intercepts was performed, considering the complex sample design. RESULTS: The prevalence of risk behaviours was 28.0% for 'low frequency of annual dental visits', 6.9% for 'low daily toothbrushing frequency', 28.8% for 'high weekly soft drink consumption', 41.7% for 'high weekly sweet consumption', 18.9% for 'cigarette experimentation' and 52.6% for 'alcoholic beverage experimentation'. The schools were classified as low (36.3%), intermediate (30.4%) and high (33.3%) OHPSE. In the adjusted model, schools with 'high OHPSE' had lower prevalence of 'low frequency of annual dental visits' (PR = 0.94 [95% CI 0.90; 0.99]), 'high weekly frequency of soft drink consumption' (PR = 0.94 [95% CI 0.89; 0.99]) and 'sweet consumption' (PR = 0.96 [95% CI 0.93; 1.00]) than those with 'low OHPSE'. In addition, schools with 'intermediate OHPSE' had higher prevalence's of 'low daily toothbrushing frequency' (PR = 1.12 [95% CI 1.03; 1.23]) and 'cigarette experimentation' (PR = 1.08 [95% CI 1.01; 1.16]) than those with 'low OHPSE'. 'Alcoholic beverage experimentation' was not associated with OHPSE. CONCLUSIONS: The potential support of schools for oral health promotion was associated with most of the oral health-related behaviours among adolescent students. Those attending schools with higher OHPSE scores reported a higher annual frequency of dental visits and a lower weekly frequency of soft drink and sweet consumption, while those in schools with intermediate OHPSE had a lower daily toothbrushing frequency and a higher rate of cigarette experimentation.

School environment and oral health promotion: the National Survey of School Health (PeNSE).

OBJECTIVE: To evaluate the potential support of schools for oral health promotion and associated factors in Brazilian capitals. METHODS: Data from 1,339 public and private schools of the 27 Brazilian capitals were obtained from the National Survey of School Health (PeNSE) 2015. Data from the capitals were obtained from the United Nations Development Program and the Department of Informatics of the Brazilian Unified Health System (Datasus). The indicator " ambiente escolar promotor de saúde bucal " (AEPSB - oral health promoting school environment) was designed from 21 variables of the school environment with possible influence on students' oral health employing the categorical principal components analysis (CATPCA). Associations between the AEPSB and characteristics of schools, capitals and regions were tested (bivariate analysis). RESULTS: Ten variables comprised CAPTCA, after excluding those with low correlation or high multicollinearity. The analysis resulted in a model with three dimensions: D1. Within-school aspects (sales of food with added sugar in the canteen and health promotion actions), D2. Aspects of the area around the school (sales of food with added sugar in alternative points) and D3. prohibitive policies at school (prohibition of alcohol and tobacco consumption). The sum of the scores of the dimensions generated the AEPSB indicator, dichotomized by the median. From the total of schools studied, 51.2% (95%CI 48.5-53.8) presented a more favorable environment for oral health (higher AEPSB). In the capitals, this percentage ranged from 36.6% (95%CI 23.4-52.2) in Rio Branco to 80.4% (95%CI 67.2-89.1) in Florianópolis. Among the Brazilian regions, it ranged from 45.5% (95%CI 40.0-51.2) in the North to 67.6% (95%CI 59.4-74.9) in the South. Higher percentages of schools with higher AEPSB were found in public schools [58.1% (95%CI 54.9-61.2)] and in capitals and regions with higher Human Development Index [61.0% (95%IC 55.8-66.0) and 57.4% (95%CI 53.2-61.4), respectively] and lower Gini index [55.7% (95%CI 51.2-60.0) and 52.8 (95%CI 49.8-55.8), respectively]. CONCLUSIONS: The potential to support oral health promotion in schools in Brazilian capitals, assessed by the AEPSB indicator, was associated with contextual factors of schools, capitals and Brazilian regions.

RESUMO OBJETIVO Avaliar o potencial de suporte do ambiente escolar para a promoção da saúde bucal e fatores associados nas capitais brasileiras. MÉTODOS Os dados de 1.339 escolas públicas e privadas das 27 capitais brasileiras foram obtidos da Pesquisa Nacional de Saúde do Escolar (PeNSE) 2015. Os dados das capitais foram obtidos do Programa das Nações Unidas para o Desenvolvimento e do Datasus. Foi elaborado o indicador "ambiente escolar promotor de saúde bucal" (AEPSB), a partir de 21 variáveis do ambiente escolar com possível influência na saúde bucal dos escolares empregando a análise de componentes principais para dados categóricos (CATPCA). Associações entre o AEPSB e características das escolas, das capitais e das regiões foram testadas (análises bivariadas). RESULTADOS Dez variáveis compuseram a CAPTCA, após exclusão daquelas com baixa correlação ou alta multicolinearidade. A análise resultou em modelo com três dimensões: D1. aspectos intraescolares (venda de alimentos com açúcar adicionado na cantina e ações de promoção de saúde), D2. aspectos do entorno escolar (venda de alimentos com açúcar adicionado em pontos alternativos) e D3. políticas proibitivas na escola (proibição do consumo de álcool e tabaco). A soma dos escores das dimensões gerou o indicador AEPSB, dicotomizado pela mediana. Do total de escolas estudadas, 51,2% (IC95% 48,5-53,8) apresentaram ambiente mais favorável à saúde bucal (maior AEPSB). Nas capitais, esse percentual variou de 36,6% (IC95% 23,4-52,2) no Rio Branco a 80,4% (IC95% 67,2-89,1) em Florianópolis. Entre as regiões brasileiras, variou de 45,5% (IC95% 40,0-51,2), no Norte a 67,6% (IC95% 59,4-74,9) no Sul. Percentuais maiores de escolas com maior AEPSB foram encontrados na rede pública [58,1% (IC95% 54,9-61,2)] e em capitais e regiões com maior índice de desenvolvimento humano [61,0% (IC95% 55,8-66,0) e 57,4% (IC95% 53,2-61,4), respectivamente] e menor índice de Gini [55,7% (IC95% 51,2-60,0) e 52,8 (IC95% 49,8-55,8), respectivamente]. CONCLUSÕES O potencial de suporte à promoção da saúde bucal de escolas das capitais brasileiras, avaliado pelo indicador AEPSB, foi associado a fatores contextuais das escolas, das capitais e das regiões brasileiras.

Perceptions and experiences of patients following treatment with single-implant mandibular overdentures: A qualitative study.

OBJECTIVE: This study aimed to explore the perceptions and long-term experiences of edentulous patients rehabilitated with single-implant mandibular overdentures (SIMO). METHODS: Thirteen participants, mean age 65.7 years, 69.2% women, who had had their treatment completed for at least 1 year, were invited and included in the study. Focus groups including four to five participants each were conducted, audio and video recorded and transcribed verbatim. Subsequently, the transcripts were analysed according to the principles of thematic analysis. RESULTS: Four major themes emerged as follows: before decision to undergo treatment with SIMO, implant surgery experience, perception of treatment outcomes and impressions about the care received. Lack of information, cost, comorbidities, older age and fear were initial barriers to the decision for treatment. Dissatisfaction with previous treatment and a sense of opportunity motivated the decision. There were ambivalent reports of absence of pain during surgery and discomfort during anaesthesia. Post-surgical recovery exceeded the pre-surgical negative expectations in most cases. There was a tendency for a positive impact of SIMO on the patients' quality of life, comprising improved ability to chew and communicate, dietary diversification, greater comfort and safety, increased self-confidence and social interaction. Few minor inconveniences were reported such as the feeling of insecurity after an episode of denture fracture and the need to use adhesive paste. Satisfaction with the care received and the trust in the dentist and dental team were evident. CONCLUSION: In general, participants presented positive perceptions and rewarding experiences after rehabilitation with SIMO.

Simultaneous oral health risk behaviors among adolescents: evidence from the National School-based Student Health Survey. / Simultaneidade de comportamentos de risco à saúde bucal em adolescentes: evidência da Pesquisa Nacional de Saúde do Escolar.

OBJECTIVE: To investigate the prevalence of simultaneous oral health risk behaviors and associated factors among Brazilian adolescents. METHODS: The study comprised data of 109,104 adolescents participating in the Brazilian National School-based Student Health Survey. The simultaneous presence of less frequent toothbrushing (E), current smoking (C), no visits to the dentist (D), low fruit intake (F), and high sugar intake (A) was assessed by comparison of observed/expected prevalence (OP/EP). Logistic regression was used to assess sociodemographic and family factors associated with the clustering patterns of oral health risk behaviors. RESULTS: The simultaneous occurrence of two or more oral health risk behaviors was of 60.40%. The highest prevalence values were found for the following patterns with OP/EP over 1.20: EDF, CFA, and EDFA. The odds for two or more combined oral health risk behaviors were higher for adolescents whose parents did not participate in homework, from public schools, males, and of Asian or Indigenous ethnicity (OR > 1.00; p < 0.05). Low family affluence level (FAL) acted as a risk factor for the pattern ECDFA (OR = 2.58; p = 0.009), while low and mean FAL functioned as protection factors for the pattern CFA (OR = 0.71; p < 0.001, and OR = 0.76; p = 0.011). CONCLUSION: The prevalence of simultaneous oral health risk behaviors was low and negatively associated with sociodemographic and family factors. Interventions aiming at reducing these behavior patterns should prioritize the groups that have been identified as being at most risk.

OBJETIVO: Identificar a prevalência da presença simultânea de comportamentos de risco à saúde bucal em adolescentes brasileiros e fatores associados. MÉTODOS: Foram utilizados dados de 109.104 escolares provenientes da Pesquisa Nacional de Saúde do Escolar (PeNSE). A presença simultânea de baixa frequência de escovação dentária (E), uso recente de cigarros (C), baixa frequência de ida ao dentista (D), baixo consumo de frutas (F) e alto consumo de alimentos que contêm açúcar adicionado (A) foi avaliada pela razão entre as prevalências observada e esperada (PO/PE). Regressão logística foi utilizada para avaliar a associação entre as combinações de comportamentos e as variáveis sociodemográficas e do contexto familiar. RESULTADOS: A ocorrência de dois ou mais comportamentos de risco à saúde bucal foi de 60,40%. As combinações mais prevalentes com razão PO/PE acima de 1,20 foram EDF, CFA e EDFA. A chance de concentrar dois ou mais comportamentos foi maior para adolescentes sem supervisão familiar dos deveres de casa, de escolas públicas, do sexo masculino e das raças indígena ou amarela (odds ratio - OR > 1,00; p < 0,05). O nível de afluência familiar baixo atuou como risco para a combinação ECDFA (OR = 2,58; p = 0,009), enquanto para a combinação CFA os níveis médio e baixo atuaram como proteção (OR = 0,71; p < 0,001 e OR = 0,76; p = 0,011). CONCLUSÃO: A prevalência da presença simultânea de comportamentos de risco à saúde bucal foi baixa e associada negativamente a fatores sociodemográficos e do contexto familiar. Intervenções que busquem reduzir os comportamentos de risco em saúde bucal em adolescentes devem priorizar os grupos identificados.

Association of breastfeeding and malocclusion in 5-year-old children: Multilevel approach.

BACKGROUND: Breastfeeding plays an important role in child health, including the development of normal dental occlusion, but large epidemiological findings on the association breastfeeding-malocclusion are lacking. AIM: To investigate the association between the proportion of breastfed children in the city level and the prevalence of malocclusion in the primary dentition at age 5. DESIGN: This cross-sectional analysis used data from national population surveys on oral health and on breastfeeding practices. Data refer to 5278 5-year-old children and 44 Brazilian towns. Information on malocclusion and individual sociodemographic characteristics were obtained from the 2010 Brazilian Oral Health Survey. Breastfeeding rates during the first year of life were extracted from the Breastfeeding Prevalence Survey in Brazilian Towns. Population sociodemographic data were analysed as confounder. Multilevel Poisson analyses were performed. RESULTS: Malocclusion prevalence was 63.3%. Towns exhibiting higher prevalence of breastfeeding among 9- to 12-month-olds presented lower prevalence of malocclusion among children at age 5 (PR 0.98; 95% CI 0.98-0.99). CONCLUSIONS: Lower prevalence of malocclusion among 5-year-old children was associated with a higher proportion of children breastfed at ages 9 to 12 months at a city level, regardless of sociodemographic factors. These findings highlight the importance of encouraging breastfeeding during a child's first year.

Socioeconomic inequalities and changes in oral health behaviors among Brazilian adolescents from 2009 to 2012.

OBJECTIVE To analyze oral health behaviors changes over time in Brazilian adolescents concerning maternal educational inequalities. METHODS Data from the Pesquisa Nacional de Saúde do Escolar (Brazilian National School Health Survey) were analyzed. The sample was composed of 60,973 and 61,145 students from 26 Brazilian state capitals and the Federal District in 2009 and 2012, respectively. The analyzed factors were oral health behaviors (toothbrushing frequency, sweets consumption, soft drink consumption, and cigarette experimentation) and sociodemographics (age, sex, race, type of school and maternal schooling). Oral health behaviors and sociodemographic factors in the two years were compared (Rao-Scott test) and relative and absolute measures of socioeconomic inequalities in health were estimated (slope index of inequality and relative concentration index), using maternal education as a socioeconomic indicator, expressed in number of years of study (> 11; 9-11; ≤ 8). RESULTS Results from 2012, when compared with those from 2009, for all maternal education categories, showed that the proportion of people with low toothbrushing frequency increased, and that consumption of sweets and soft drinks and cigarette experimentation decreased. In private schools, positive slope index of inequality and relative concentration index indicated higher soft drink consumption in 2012 and higher cigarette experimentation in both years among students who reported greater maternal schooling, with no significant change in inequalities. In public schools, negative slope index of inequality and relative concentration index indicated higher soft drink consumption among students who reported lower maternal schooling in both years, with no significant change overtime. The positive relative concentration index indicated inequality in 2009 for cigarette experimentation, with a higher prevalence among students who reported greater maternal schooling. There were no inequalities for toothbrushing frequency or sweets consumption. CONCLUSIONS There were changes in the prevalences of oral health behaviors during the analyzed period; however, these changes were not related to maternal education inequalities.

Dental fluorosis: prevalence and associated factors in 12-year-old schoolchildren in Goiânia, Goiás.

OBJECTIVE: To describe the prevalence of dental fluorosis, to investigate its association with individual and contextual variables among 12-year-old schoolchildren, and to determine whether there were changes in the prevalence of this condition from 2003 to 2010. METHODS: This cross-sectional study used data from an oral health survey carried out in Goiânia, Goiás, in 2010 (n = 2,075), and secondary data from the files of the local health authority. Clinical data were collected through oral examinations in public and private schools. The dependent variable was the presence of dental fluorosis, assessed using the Dean Index. The independent individual variables were sociodemographic characteristics (the child's gender and race, and the mother's level of schooling) and those related to clinical conditions (caries experience, evaluated using Decayed, Missing, and Filled teeth index; and presence of periodontal calculus and/or bleeding, evaluated using Community Periodontal Index). The contextual variables were linked to the school (type and existence of toothbrushing program) and its geographic location in the city's health districts. The Rao-Scott test was performed, and the percentage difference between the prevalences in the period from 2003 to 2010 was calculated. RESULTS: The prevalence of dental fluorosis in 2010 was 18.7%, being distributed as very mild (11.2%), mild (4.4%), moderate (2.6%), and severe (0.5%). No significant association was found between prevalence of dental fluorosis and the investigated variables. The prevalence of fluorosis increased 230% from 2003 to 2010, and such difference was significant. CONCLUSIONS: The prevalence of dental fluorosis was low, predominantly of the very mild degree, has increased over a 7-year period, and was not associated with the individual or contextual factors studied.

Individual and contextual determinants of malocclusion in 12-year-old schoolchildren in a Brazilian city.

The aim of this study was to describe malocclusion prevalence and its association with individual and contextual factors among Brazilian 12-year-old schoolchildren. This cross-sectional study included data from an oral health survey carried out in Goiânia, Brazil (n = 2,075), and data from the files of the local health authority. The data were collected through oral clinical examinations. The Dental Aesthetic Index (DAI) was used to assess occlusion. The presence of malocclusion (DAI > 25) was used as the dependent variable. The individual independent variables consisted of adolescents' sex and race and their mothers' level of schooling. The clinical variables were caries experience and presence of adverse periodontal condition (calculus and/or gingival bleeding). The contextual variables included type of school and the location of schools in the city's health districts. The Rao-Scott test and multilevel logistic regression were performed. The prevalence of malocclusion was 40.1%. In the final model, significantly higher rates of malocclusion were found among those who attended schools located in less affluent health districts and whose mothers had fewer years of education. Rates were also higher among those presenting calculus and/or gingival bleeding. Malocclusion demonstrated a high prevalence rate and the inequalities in its distribution were determined by individual and contextual factors.

OBJETIVO Analisar a evolução de comportamentos em saúde bucal em adolescentes em relação às desigualdades da escolaridade materna.MÉTODOS Foram analisados dados da Pesquisa Nacional de Saúde do Escolar. A amostra foi composta por 60.973 e 61.145 escolares do nono ano das 26 capitais brasileiras e do Distrito Federal em 2009 e 2012, respectivamente. Foram analisados comportamentos em saúde bucal (frequência de escovação dentária, consumo de guloseimas, consumo de refrigerantes e experimentação de cigarros) e variáveis sociodemográficas (idade, sexo, raça/cor, tipo de escola e escolaridade materna). Compararam-se os comportamentos em saúde bucal e os fatores sociodemográficos nos dois anos (teste de Rao-Scott) e calcularam-se medidas de desigualdades socioeconômicas absolutas e relativas em saúde (coeficiente angular de desigualdade e índice de concentração relativa), utilizando-se como indicador a escolaridade materna expressa em anos de estudo (> 11; 9-11; ≤ 8).RESULTADOS Quando comparado 2012 em relação a 2009, para todas as categorias de escolaridade materna, observou-se aumento da proporção de pessoas com baixa frequência de escovação, e diminuição do consumo de guloseimas e refrigerantes e da experimentação de cigarros. Em escolas privadas, o coeficiente angular de desigualdade e o índice de concentração relativa positivos indicaram maior consumo de refrigerantes em 2012 e maior experimentação de cigarros nos dois anos entre aqueles cujas mães tinham maior escolaridade, sem mudança significativa das desigualdades. Em escolas públicas, o coeficiente angular de desigualdade e o índice de concentração relativa negativos indicaram maior consumo de refrigerantes entre aqueles cujas mães tinham, nos dois anos estudados, menor escolaridade, sem mudança significativa. Já o índice de concentração relativa positivo indicou desigualdade em 2009 para experimentação de cigarros, com maior prevalência entre aqueles cujas mães tinham maior escolaridade. Não houve desigualdade para frequência de escovação e consumo de guloseimas.CONCLUSÕES As prevalências dos comportamentos em saúde bucal apresentaram mudanças no período investigado. No entanto, tais mudanças não foram relacionadas às desigualdades de escolaridade materna.

Individual and contextual determinants of periodontal health in 12-year-old schoolchildren in a brazilian capital city.

The study aimed to describe periodontal health status and its association with individual and contextual factors among 12-year-old schoolchildren in a midwest Brazilian capital city. This cross-sectional study included data from an oral health survey carried out in 2010 in the city of Goiania, Brazil (n = 2, 075) and secondary data obtained from the local health authority. Data were collected through oral clinical examinations and interviews. For assessment of periodontal status two components of the community periodontal index (CPI) were used: calculus and bleeding after probing. Dependent variable was presence of any periodontal condition. Independent individual variables were the children's sex and color/race, and their mother's level of schooling. Contextual variables were related to the schools (type and existence of toothbrushing program) and its geographic location in the health districts. Rao-Scott test and multilevel Poisson analysis were performed. The prevalence of calculus and/or bleeding was 7%. Brown color, public schools, and those located in health district with intermediate socioeconomic indicators were associated to a higher prevalence of this condition. The prevalence of adverse periodontal condition was low and the inequalities in its distribution were determined by individual as well as contextual factors related to the schools and the geographic area.
