Contextual and individual factors associated with traumatic dental injuries in deprived 12-year-old schoolchildren: A cohort study.

AIM: Traumatic dental injuries (TDIs) among children and adolescents have been acknowledged as of public health concern worldwide. The aim of the study was to assess the relationship between contextual and individual characteristics and TDIs in 12-year-old schoolchildren. MATERIALS AND METHODS: A cohort study was conducted with 355 schoolchildren living in deprived communities in the city of Manaus, Brazil. Contextual factors (place of residence and socio-economic indicators) and individual characteristics, including sex, family income, parents/guardians years of schooling, overjet and open bite (Dental Aesthetic Index), self-esteem (Rosenberg Self-Esteem Scale), sense of coherence (Sense of Coherence Scale), oral health beliefs, social support (Social Support Appraisals) were assessed at baseline. TDIs were measured at baseline and at 2-year follow-up using the O'Brien Index. Data were analysed through confirmatory factor analysis and structural equation modeling. RESULTS: The baseline prevalence of TDIs was 17.6% and the incidence of TDIs at 2-year follow-up was 26.8%. Better psychosocial status had a direct protective effect on the incidence of TDIs (ß = -.184). Better contextual characteristics (ß = -.135) and greater overjet (ß = -.203) were directly associated with poor psychosocial status. Higher schooling of parents/guardians directly predicted better psychosocial status (ß = .154). Psychosocial status mediated the relationship of greater overjet (ß = .036), contextual factors (ß = .024) and parental/guardian schooling (ß = -.027) with TDIs. CONCLUSIONS: Contextual factors and individual characteristics predicted TDIs. Psychosocial status was a relevant individual attribute in the causal network of TDIs, due to the direct effect on the incidence of TDIs as well as a mediator on the influence of contextual factors, overjet and parents/guardians schooling on the incidence of TDIs.

The association between malocclusion and health-related quality of life in adolescents: A mediation analysis.

This study investigated the role of oral health-related functional limitations and social well-being, self-perceived health, psychosocial factors, and social support in mediating the impact of malocclusion on health-related quality of life (HRQoL). A school-based 6-month cohort study was conducted with 376 12-year-old deprived adolescents. Measures at baseline included malocclusion (DAI score), dental caries, sociodemographic characteristics, psychosocial traits (self-esteem, sense of coherence, oral health beliefs), and social support. The oral health-related functional limitations and symptoms (social well-being) domains of the CPQ11-14 , self-perceived health, and HRQoL (Kiddo-KINDL) were evaluated at the 6-month follow-up. Associations between observed and latent variables (social support, psychosocial factors, and HRQoL) were evaluated using structural equation modelling, according to the Wilson and Cleary theoretical model. Malocclusion was indirectly associated with worse HRQoL, mediated by functional limitations, social well-being, and self-perceived health. Better psychosocial status was directly associated with better HRQoL, and higher social support was indirectly associated with better HRQoL via psychosocial factors. Dental caries experience, female sex, and lower family income were indirectly associated with worse HRQoL. The impact of malocclusion on HRQoL was mediated by oral health-related functional limitations, social well-being, and self-perceived health. Sociodemographic and psychosocial factors, and social support also impacted HRQoL.

Prevalence of dental caries, periodontal disease, malocclusion, and tooth wear in indigenous populations in Brazil: a systematic review and meta-analysis.

The aim of this review was to evaluate the prevalence of dental caries, periodontal disease, malocclusion, and tooth wear in indigenous in Brazil. A systematic review of observational studies was performed according to the PRISMA guidelines (CRD42020218704). The search strategy involved the electronic databases of Embase, LILACS, PubMed, Web of Science, Scopus, and the CAPES Theses and Dissertations for gray literature. The eligibility criteria consisted of publications that assessed the prevalence of oral conditions in indigenous populations in Brazil. Studies with indigenous people living in urban area were excluded. The risk of bias was evaluated by using JBI Critical Appraisal for prevalence studies. Thirty studies were included in the review, and the majority showed a low risk of bias. A meta-analysis of 20 studies was conducted using the random-effects model and a 95% confidence interval. Several ethnicities were studied in isolation or in groups (n = 7,627 for dental caries; n = 2,774 for periodontal disease; n = 1,067 for malocclusion; n = 150 for tooth wear). The prevalence of caries ranged from 50% among indigenous people aged 18-36 months to 100% among those aged 65-74 years. The prevalence of periodontal disease ranged from 58% to 83%. The prevalence of malocclusion was 43%. Tooth wear was assessed in only one ethnic group and showed a prevalence of 100% in indigenous people aged >18 years. The certainty of evidence assessed by the GRADE system ranged from very low to moderate. This systematic review showed significant differences in the prevalence of dental caries, periodontal disease and malocclusion between indigenous population groups and territories in which indigenous people live.

Does using the sociodental approach in oral health care influence use of dental services and oral health of adolescents living in deprived communities? a one-year follow up study.

BACKGROUND: Oral health needs assessment is important for oral health care planning. This study compared dental treatment needs between normative and sociodental needs. We also longitudinally examined the relationships of baseline sociodental needs measures and socioeconomic status with one-year follow up measures of use of dental services, dental caries, filled teeth, and oral health-related quality of life (OHRQoL). METHODS: A prospective study was conducted with 12-year-old adolescents from public schools in deprived communities in the city of Manaus, Brazil. Validated questionnaires were used to collect adolescents' sex and socioeconomic status, OHRQoL (CPQ11 - 14) and behaviours (sugar intake, frequency of toothbrushing, regular use of fluoridated toothpaste and pattern of dental attendance). Normative need was assessed according to decayed teeth, clinical consequences of untreated dental caries, malocclusion, dental trauma, and dental calculus. The relationships between variables were tested thorough Structural equation modelling. RESULTS: Overall 95.5% of adolescents had normative dental treatment needs. Of these, 9.4% were classified as high level of propensity. Higher normative/impact need and greater propensity-related need directly predicted use of dental services at one-year follow up. The latter mediated the association of normative/impact need and propensity-related need with incidence of dental caries and filled teeth. Normative/impact need and use of dental services were directly associated with filled teeth at one-year follow up. Poor OHRQoL at one-year follow-up was directly predicted by higher normative/impact need at baseline and less filled teeth at one-year follow up. Greater socioeconomic status was directly associated with better propensity-related need. Socioeconomic status indirectly predicted incidence of dental caries and filled teeth via propensity-related need and use of dental services. CONCLUSIONS: Sociodental needs measures were related to use of dental services, dental caries, filled teeth and OHRQoL after one year among adolescents living in deprived communities. Adolescents with dental needs treatment priorities according to the sociodental approach had more filled teeth via use of dental services. Dental services utilisation did not attenuate the impact of normative and impact-related need on dental caries incidence and poor OHRQoL after one year. Our findings suggest the importance of developing oral health promotion and enhancing access to dental care to improve oral health of adolescents living in deprived communities.

Socio-economic status, psychosocial factors, health behaviours and incidence of dental caries in 12-year-old children living in deprived communities in Manaus, Brazil.

OBJECTIVES: This study examines the relationships between socio-economic status, psychosocial factors, health-related behaviours and the incidence of dental caries amongst 12-year-old schoolchildren living in deprived communities in Manaus, Brazil. METHODS: A longitudinal study involving 312 children aged 12 years was conducted in the city of Manaus, Brazil. Baseline data including socio-economic status (number of goods, household overcrowding, parents' schooling, family income), psychosocial factors (sense of coherence [SOC-13], social support [Social Support Appraisals questionnaire]) and health-related behaviours (frequency of toothbrushing, sugar consumption, sedentary behaviour) were collected through structured questionnaires. The number of decayed teeth was clinically assessed at baseline and one-year follow-up. A hypothesised model evaluating the direct and indirect pathways between the variables was tested using confirmatory factor analysis and structural equation modelling. RESULTS: The incidence of dental caries at the one-year follow-up was 25.6%. Sugar consumption (ß = 0.103) and sedentary behaviour (ß = 0.102) directly predicted the incidence of dental caries. A higher socio-economic status was directly linked with lower sugar consumption (ß = -0.243) and higher sedentary behaviour (ß = 0.227). Higher social support directly predicted lower sugar consumption (ß = -0.114). Lower socio-economic status (ß = -0.046) and lower social support (ß = -0.026) indirectly predicted the incidence of dental caries via sugar consumption and sedentary behaviour. CONCLUSIONS: In the population studied, sugar consumption and sedentary behaviour are meaningful predictors of the incidence of dental caries amongst schoolchildren living in deprived communities. Indirect pathways of lower socio-economic status and low social support with dental caries incidence via sugar consumption and sedentary behaviour were detected. These findings should be considered in oral interventions and oral health care policies to prevent dental caries amongst children living in deprivation. CLINICAL SIGNIFICANCE: Social conditions, social support, sedentary behaviour and sugar consumption directly influence dental caries in children.

Parents' sense of coherence in the use of dental services by children aged 12 years old in the city Manaus/AM

Aim The aim of this study was to evaluate the association between the sense of coherence (SOC) of parents/guardians and the use of dental services by children who are 12 years old. Methods This is a cross-sectional study conducted in the eastern zone of the city of Manaus, with 358 children enrolled in the 7th grade in the municipal public school system. Data collection was performed through self-administered questionnaires sent to parents/guardians, which contained questions about socioeconomic conditions, use of dental services by children and Antonovsky's SOC-13 scale. Data were examined by descriptive and bivariate analysis, using the Chi-square test, with a 5% significance level. Results Of the 358 children, 58.4% were female; in addition, 75.4% of the parents/guardians self-reported to be brown and 39.9% of them had a family income of ½ to 1 minimum wage. SOC was categorized as strong SOC and weak SOC by the median. The association between strong or weak SOC and the use of dental services in terms of frequency (p= 0.839) and reason for last visit (p= 0.384), was not significant. Conclusion It was concluded that SOC of parents/guardians and utilization of dental services by children were not associated.

Prevalence of dental caries, periodontal disease, malocclusion, and tooth wear in indigenous populations in Brazil: a systematic review and meta-analysis

Abstract The aim of this review was to evaluate the prevalence of dental caries, periodontal disease, malocclusion, and tooth wear in indigenous in Brazil. A systematic review of observational studies was performed according to the PRISMA guidelines (CRD42020218704). The search strategy involved the electronic databases of Embase, LILACS, PubMed, Web of Science, Scopus, and the CAPES Theses and Dissertations for gray literature.

Psychometric Properties of the Brazilian Version of GOHAI among Community-Dwelling Elderly People.

This study assessed the psychometric properties of the Brazilian version of the Geriatric Oral Health Assessment Index (GOHAI). A representative sample of 613 community-dwelling elderly people aged from 65 to 74 years was selected. Sociodemographic data, GOHAI and self-perceived oral health measures were collected. Dental clinical measures were obtained through oral examinations. The dimensional structure and adequacy of components were assessed using Confirmatory Factor Analysis (CFA), inter-item correlations and item-scale correlations. Reliability was evaluated by internal consistency and Intraclass Correlation Coefficients. Correlations between GOHAI scores and self-reported oral health measures were conducted to assess convergent validity. The relationship between dental clinical measures and GOHAI was tested through Poisson Regression to examine discriminant validity. The link between GOHAI items and dimensions was supported by CFA. Item 12 showed a poor factor loading. The inter-item correlations varied from 0.047 to 0.442, and item-scale correlations ranged from 0.305 to 0.612. Cronbach's alpha was 0.704. The test-retest correlation for GOHAI was 0.882. GOHAI scores were correlated by self-rated oral health measures. Poor dental clinical measures were associated with GOHAI. The Brazilian version of GOHAI showed adequate psychometric properties. However, the weak dimensional structure of GOHAI suggests the need to perform cross-cultural adaptation of GOHAI for Brazilian elderly people.

The role of dental pain and psychosocial factors on the relationship between dental caries and oral health-related quality of life in children.

BACKGROUND: To examine the role of dental pain, sense of coherence (SOC) and social support on the relationship between dental caries and oral health-related quality of life (OHRQoL) in children aged 12 years. METHODS: A cross-sectional study involving 400 schoolchildren selected from public schools in a socioeconomically disadvantaged region in the city of Manaus, Brazil was carried out. The predictors of OHRQoL were selected according to the Wilson and Cleary theoretical model, including number of decayed teeth and its clinical consequence (component D of the DMFT index and PUFA/pufa index), dental pain (symptom status), and SOC and social support (individual and environmental characteristics). Statistical analysis was conducted through structural equation modelling and multivariable negative binomial regression. The significance level established for all analyses was 5%. RESULTS: Number of dental caries was indirectly linked with OHRQoL (ß = 0.19, 95% CI 0.11/0.29) through dental pain, SOC and social support. Clinical consequences of untreated caries directly predicted poor OHRQoL (ß = 0.12, 95% CI 0.01/0.23). Dental pain, SOC and social support did not moderate the effect of dental caries measures on OHRQoL. CONCLUSION: Our findings suggest the role of dental pain, SOC and social support as mediator factors on the link between dental caries and OHRQoL. Tackling dental caries along with psychosocial factors may attenuated the impact of oral health on OHRQoL in children.

The influence of protective psychosocial factors on the incidence of dental pain.

OBJECTIVE: To investigate the influence of protective psychosocial factors on the incidence of dental pain in the last six months among 12-year-old children living in Manaus (AM). METHODS: A prospective school-based cohort study was conducted with 210 12-year-old students enrolled in public schools in the eastern zone of Manaus (AM). Students were followed up for two years. Validated questionnaires were used to assess sociodemographic characteristics, protective psychosocial factors, including sense of coherence, social support, and self-esteem at baseline and after two years. Calibrated examiners clinically assessed dental caries and gingival bleeding. Multivariate multilevel Poisson regression was used to estimate the relative risk (RR) and 95% confidence interval (95%CI) between the changes on psychosocial factors scores and incidence of dental pain, adjusted for psychosocial factors scores at baseline, dental health insurance, frequency of tooth brushing, and dental caries. RESULTS: Mean scores for sense of coherence and social support reduced significantly from baseline to 2-year follow-up. The incidence of dental pain along the two-year follow-up was 28.6%. The risk of dental pain was 14% higher for every 10 points in the mean reduction of sense of coherence score (RR = 1.14; 95%CI: 1.02-1.20), and 6% higher for every 10 points of the mean reduction in social support score (RR = 1.06; 95%CI: 1.01-1.11). Change on self-esteem was not associated with risk of dental pain. CONCLUSION: Change on sense of coherence and social support over the two-year period influenced the incidence of dental pain among children, suggesting that protective psychosocial factors, health behaviours, dental health insurance, and clinical oral condition have an important role in the incidence of dental pain.

Fluoride toothpaste, sanitary surveillance and the SUS: the case of Manaus-AM, Brazil.

OBJECTIVE: To determine the anticaries potential of toothpastes distributed by the primary health care public clinics (UBS) of Manaus, AM. METHODS: Ninety-nine tubes of toothpaste from four commercial brands were collected from October 7, 2019 to October 11, 2019 in 16 UBS. They were assigned a code by brand and source UBS. According to the information on the packaging, the four brands and their batches were formulated with sodium monofluorophosphate (Na2FPO3) and most (91%) had calcium carbonate (CaCO3) as an abrasive. We determined the concentrations of total fluoride (TF = TSF + InsF) and total soluble fluoride (TSF = F ions- or FPO32-), to certify whether they were in compliance with resolution ANVISA RDC No. 530 (maximum of 1,500 ppm TF) and whether they had anticaries potential (minimum of 1,000 ppm TSF). The analyses were performed with a ion- specific electrode. RESULTS: The concentrations (ppm F) of TF [mean; standard deviation (SD); n] found in toothpaste brands A (1,502.3; SD = 45.6; n = 33), B (1,135.5; SD = 52.7; n = 48) and D (936.8; SD = 20.5; N = 8) were close to those stated on the package, 1,500, 1,100 and 1,000 ppm F, respectively. In toothpaste C, we found a mean of 274.1 ppm (SD = 219.7; n = 10) of TF, which diverges from the declared concentration of 1,500 ppm F. In addition, the five tubes of lot no. 11681118 of toothpaste C did not contain fluoride. Regarding TSF, with the exception of toothpaste D (937.9; SD = 40.29), the others had a lower concentration than their respective TF. CONCLUSION: We found serious problems of quantity and quality of fluoride in toothpaste distributed by the SUS in Manaus, which shows the need for surveillance of these products and confirms the urgency of revising resolution RDC No. 530.

RESUMO OBJETIVO Determinar o potencial anticárie dos dentifrícios distribuídos pelas unidades básicas de saúde (UBS) de Manaus-AM. MÉTODOS Noventa e nove bisnagas de dentifrícios de quatro marcas comerciais foram coletadas de 7 de outubro de 2019 a 11 de outubro de 2019 em 16 UBS, que foram codificados por marca e UBS de origem. De acordo com a embalagem, os dentifrícios das quatro marcas e seus lotes foram formulados com monofluorofosfato de sódio (Na2FPO3) e a maioria (91%) tinha carbonato de cálcio (CaCO3) como abrasivo. Foram determinadas as concentrações de fluoreto total (FT = FST + Fins) e de fluoreto solúvel total (FST = íons F- ou FPO32-), para certificar se atendiam à resolução ANVISA RDC Nº 530 (máximo de 1.500 ppm de FT) e se tinham potencial anticárie (mínimo de 1.000 ppm de FST). As análises foram feitas com eletrodo íon específico. RESULTADOS As concentrações (ppm F) de FT [média; desvio padrão (DP); n] encontradas nos dentifrícios A (1.502,3; DP = 45,6; n = 33), B (1.135,5; DP = 52,7; n = 48) e D (936,8; DP = 20,5; n = 8) foram próximas ao descrito na embalagem, 1.500, 1.100 e 1.000 ppm F, respectivamente. No dentifrício C, foi encontrada média de 274,1 ppm (DP = 219,7; n = 10) de FT, divergindo da concentração declarada de 1.500 ppm F. Em acréscimo, as cinco bisnagas do lote no 11681118 do dentifrício C não foram fluoretadas. Quanto ao FST, à exceção do dentifrício D (937,9; DP = 40,29), os demais apresentaram concentração inferior ao seu respectivo FT. CONCLUSÃO Observou-se problemas graves de quantidade e qualidade do fluoreto nos dentifrícios distribuídos pelo SUS em Manaus, mostrando a necessidade de vigilância desses produtos e ratificando a urgência da revisão da resolução ANVISA RDC Nº 530.

Fluoride Concentration in Public Water Supply in a City in the Amazon Region

Abstract Objective: To analyze the fluoride concentration in the public water supply in Manaus, Brazil. Material and Methods: Water samples were collected in 50 mL polyethylene bottles, identified, and labeled. The collection was performed from September 2016 to August 2018. For the selection of collection points, all neighborhoods of the city of Manaus, divided into four health districts (North, South, East, and West), were mapped. From each district, 30 samples were collected, totaling 120 monthly samples. Water samples were analyzed using an ion analyzer, ORION 720-A, and a specific electrode, ORION 96-09. The ion analyzer and electrode were calibrated in standard solutions. The levels were classified in intervals based on technical consensus to guide the health surveillance agencies. Results: Of the 2,874 water samples, 50.3% were within the recommended range, and 49.7% were inadequate, with 31.6% considered above the parameters and 18.1% below. Among the districts, the North had the highest percentages of unsatisfactory samples, resulting in limited action to prevent tooth decay. During the 24 months of analysis, there were large oscillations in the values in all four districts of Manaus. Conclusion: Results reinforce the importance of heterocontrol for the city to guarantee the effectiveness of this public health measure.

Change on self-esteem was not associated with risk of dental pain. CONCLUSION Change on sense of coherence and social support over the two-year period influenced the incidence of dental pain among children, suggesting that protective psychosocial factors, health behaviours, dental health insurance, and clinical oral condition have an important role in the incidence of dental pain.

RESUMO OBJETIVO Investigar a influência de fatores psicossociais protetores sobre a incidência de dor dentária nos últimos seis meses em crianças de 12 anos residentes em Manaus (AM). MÉTODOS Um estudo de coorte prospectivo de base escolar foi realizado com 210 alunos de 12 anos, matriculados em escolas públicas da zona leste de Manaus (AM) que foram acompanhados por dois anos. Questionários validados foram usados para avaliar características sociodemográficas, fatores psicossociais protetores, incluindo senso de coerência, apoio social e autoestima na linha de base e após dois anos. Examinadores calibrados avaliaram clinicamente cárie dentária e sangramento gengival. Regressão de Poisson multinível multivariada foi usada para estimar o risco relativo (RR) e o intervalo de confiança de 95% (IC95%) entre a variação dos escores dos fatores psicossociais e a incidência de dor dentária, ajustada para os escores dos fatores psicossociais na linha de base, plano de saúde odontológico, frequência de escovação dentária e cárie dentária. RESULTADOS As médias dos escores do senso de coerência e do apoio social reduziram significativamente entre linha de base e seguimento de dois anos. A incidência de dor dentária no seguimento de dois anos foi 28,6%. O risco de dor dentária foi 14% maior para cada 10 pontos na redução média do escore do senso de coerência (RR = 1,14; IC95% 1,02-1,20), e 6% maior para cada 10 pontos na redução média do escore do apoio social (RR = 1,06; IC95% 1,01-1,11). A mudança na autoestima não foi associada ao risco de dor dentária. CONCLUSÃO A variação do senso de coerência e do apoio social no período de dois anos influenciou a incidência de dor dentária em crianças, sugerindo que fatores psicossociais protetores, comportamentos em saúde, plano odontológico e a condição clínica bucal desempenham um papel importante na incidência da dor dentária.

The influence of change on sense of coherence on dental services use among adolescents: a two-year prospective follow-up study.

BACKGROUND: To investigate the influence of change on sense of coherence (SOC) on dental services use in adolescents over a two-year period. METHODS: A prospective follow-up study was conducted involving 334 12-year-old adolescents from public schools in the city of Manaus, Amazonas, Brazil. The predictors of use of dental services in the last 12 months were selected according to the Andersen's behavioural theoretical model. The predisposing factors included sex, self-reported skin colour and SOC. The enabling factors were dental insurance, monthly family income and parents/guardians schooling. Dental pain, perceived oral health status, dental caries and gingival status were used to assess need factors. Multivariable Poisson regression with robust variance was used to estimate incidence-rate ratios (IRR) and 95% confidence intervals between the independent variables and use of dental services. RESULTS: Adolescent's SOC scores decreased significantly between baseline and one-year follow-up. SOC decline decreased the likelihood of using dental services in the last 12 months (IRR = 0.96 95%CI 0.92-0.99). Dental caries (IRR = 1.03 95%CI 1.01-1.04) and gingival bleeding (IRR = 1.01 95%CI 1.01-1.02) remained associated with use of dental services in the last 12 months. Adolescents with dental pain were more likely to have visited a dentist in the last year (IRR = 1.03, 95%CI 1.01-1.06). CONCLUSION: SOC decrease over one-year period was a meaningful factor of dental services use among 12-year-old adolescents. Dental pain and clinical conditions were also relevant factors that can influence use of dental services in this group.

Clinical consequences of untreated dental caries and school performance in low-income adolescents.

BACKGROUND: The possible link between dental status and school performance has been investigated. The influence of the clinical consequences of untreated dental caries in this association, however, has been minimally explored. AIM: To assess the relationship between clinical consequences of untreated dental caries and school performance in adolescents, and to examine the demographics and socioeconomic status pathways by which clinical consequences of untreated dental caries is associated with school performance. DESIGN: A cross-sectional study involving 363 low-income school adolescents was conducted in the city of Manaus, Brazil. Dental clinical measures were registered by five calibrated examiners to evaluate dental caries experience (decayed, missing, and filled teeth index [DMFT]) and clinical sequelae of dental caries (PUFA/pufa index). School performance was assessed using school grade history obtained from official records. Statistical analysis was conducted using pathway analysis to estimate beta coefficients (ß) of the direct and indirect effects between variables. RESULTS: DMFT and PUFA/pufa mean were 1.93 and 0.30, respectively. PUFA/pufa scores (ß = -0.19) and male sex (ß = 0.35) directly predicted poor school performance. DMFT was indirectly linked to poor school performance via PUFA/pufa scores (ß = -0.03). CONCLUSIONS: Dental caries and clinical consequences of dental caries were important predictors of poor school performance in low-income adolescents via direct and indirect effects.

Construção de um indicador multidimensional de saúde bucal para a população idosa da cidade de Manaus, AM / Construction of a multidimensional oral health indicator for the older population in the city of Manaus-Amazonas

Resumo Objetivo Produzir um indicador multidimensional de saúde bucal, a partir de variáveis dentárias e não dentárias, para a pessoa idosa da zona urbana do município de Manaus, AM, Brasil. Método Os dados utilizados são oriundos de um estudo transversal de base populacional conduzido no ano de 2008, com indivíduos de 65 a 74 anos de idade, aleatoriamente selecionados, residentes na cidade de Manaus. Para a produção do indicador proposto, consideraram-se as variáveis dentárias (CPO-D - Índice de Dentes Perdidos, Cariados e Obturados; CPI - Índice Periodontal Comunitário; PIP- Índice de Perda de Inserção Periodontal) e não dentárias (socioeconômicas e índice GOHAI - General Oral Health Assessment Index). Uma Análise Fatorial Exploratória sintetizou essas variáveis, facilitando a construção do indicador multidimensional. Resultados A análise gerou três fatores que, em conjunto, explicaram 72,9% da variância do modelo (KMO = 0,749 e p< 0,001 para o teste de esfericidade de Bartlett). Esses três fatores foram reduzidos à variável "soma", calculada a partir da soma dos escores fatoriais por indivíduo. A mediana dessa nova variável foi o valor de referência para categorização da condição de saúde bucal do indivíduo em "favorável" ou "desfavorável". Conclusão O indicador foi capaz de agregar diversas dimensões da saúde bucal em uma única medida, além de possibilitar sua reprodutibilidade para construção de outros indicadores de saúde.

Abstract Objective Produce a multidimensional indicator of oral health, based on dental and non-dental variables, for the older adult in the urban area of the city of Manaus-AM. Method The data used are from a cross-sectional population-based study conducted in 2008 with randomly selected individuals aged 65 to 74 years, residing in the city of Manaus. To produce the proposed indicator, the dental variables (DMFT- Decayed, Missing and Filled Teeth; CPI- Community Periodontal Index; PIP- Periodontal Insertion Loss Index) and non-dental (socioeconomic and index GOHAI- General Oral Health Assessment Index) were considered. An exploratory factor analysis synthesized these variables, facilitating the construction of the multidimensional indicator Results The analysis generated three factors that, together, explained 72.9% of the model's variance (KMO = 0.749 and p<0.001 for Bartlett's test of sphericity). These three factors were reduced to the "sum" variable, calculated from the sum of the factor scores per individual. The median of this new variable was the reference value for categorizing the individual's oral health condition into "favorable" or "unfavorable". Conclusion The indicator was able to aggregate several dimensions of oral health into a single measure, in addition to enabling its reproducibility for the construction of other health status indicators.

Clinical Consequences of Untreated Dental Caries, Individual Characteristics, and Environmental Factors on Self-Reported Oral Health Measures in Adolescents: A Follow-Up Prevalence Study.

BACKGROUND/AIMS: This study evaluated the relationships of clinical consequences of untreated dental caries, individual characteristics, and environmental factors on self-reported oral health measures in adolescents. METHODS: A follow-up prevalence study was conducted involving 406 twelve-year-old adolescents selected from public schools in the eastern area of the city of Manaus, Brazil. Baseline data included clinical consequences of untreated caries (PUFA/pufa index), DMFT, sociodemographic characteristics (sex, parental schooling, and family income), psychosocial factors (sense of coherence [SOC-13 scale], oral health beliefs and self-esteem [Rosenberg Self-Esteem Scale]), and social support (SSA questionnaire). Oral health-related quality of life (OHRQoL [CPQ11-14]) and self-rated oral health were assessed at the 6-month follow-up. Structural equation modelling was used to explore the relationships between variables according to the Wilson and Cleary model. RESULTS: The prevalence of PUFA/pufa was 17.8% and mean DMFT was 1.5. The number of teeth with clinical consequences of untreated caries predicted poor self-rated oral health at the 6-month follow-up. Low parental schooling predicted low family income and clinical consequences of untreated dental caries. Psychosocial factors predicted OHRQoL directly and self-rated oral health indirectly. OHRQoL was linked to self-rated oral health. Clinical consequences of untreated dental caries mediated the relationship of parental schooling with OHRQoL and self-rated oral health. OHRQoL mediated the relationship of psychosocial factors and sex with self-rated oral health. Clinical consequences of untreated dental caries was associated with adolescents' self-rated oral health. Furthermore, the former was an important mediator on the link between low parental education and adolescents' self-reported oral health measures. CONCLUSIONS: Socioeconomic status, psychosocial factors, and social support were related to OHRQoL and self-rated oral health via direct and indirect pathways.
