Contributions of school context to caries on anterior teeth: a multilevel analysis

OBJECTIVE

To investigate whether oral health literacy (OHL) and school context are associated with untreated dental caries on the anterior teeth of adolescents.

METHODS

A representative cross-sectional study was conducted with 746 students aging 15 to 19 in the city of Campina Grande, Brazil. The guardians answered a questionnaire addressing sociodemographic data and the absence/presence of private health insurance. Two examiners were trained for the diagnosis of dental caries using the Nyvad criteria and the measurement of OHL using the Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) (Kappa > 0.80). Contextual aspects of the schools were obtained from the 2017 National School Census. Descriptive statistics were conducted, followed by unadjusted and adjusted robust negative binomial regression for complex samples (p < 0.05).

RESULTS

The average number of anterior teeth with untreated caries was 0.95 (SD = 1.77). Among individual factors, the male sex (RR = 1.64; 95%CI: 1.24–2.16), inadequate level of OHL (RR = 2.03; 95%CI: 1.13–1.63), marginal level of OHL (RR = 1.87; 95%CI: 1.05–3.33) and not having private health insurance (RR = 1.34; 95%CI: 1.07–1.68) were associated with untreated caries on anterior teeth. Among school contextual factors, the number of students in the classroom (RR = 2.64; 95%CI: 1.78–3.93), number of public oral health services in the district (RR = 0.14; 95%CI: 0.05–0.39) and average income of the district in which the school is located (RR = 0.99; 95%CI: 0.98–0.99) were associated with the outcome.

CONCLUSIONS

Sociodemographic factors, having private health insurance, OHL, and school context exerted an influence on the occurrence of untreated dental caries on anterior teeth in adolescents aging 15 to 19.

Factors associated with prehypertension and hypertension among healthcare workers working in high-complexity services

The objective was to estimate the prevalence and factors associated with prehypertension and hypertension among health workers who work in high-complexity services for critically-ill and chronic patients. An epidemiological, cross-sectional study was carried out with 490 health workers in the macroregional region of Northern Minas Gerais, Brazil. The dependent variable blood pressure (BP) was categorized as normal BP, prehypertension and hypertension. Multinomial Logistic Regression was used for the multiple analysis. The prevalence of arterial hypertension was 21.8% and that of prehypertension was 25.9%. The chances of developing arterial hypertension and prehypertension were higher in male professionals, aged ≥40 years, in civil servant workers and those who were obese or overweight. The use of continuous medication and night shift work were associated with hypertension and prehypertension, respectively. The prevalence of arterial hypertension in the group of workers was lower than that of the Brazilian population. It is necessary to carry out studies with workers from this group and investments are required in preventive measures that encourage a change to a healthy lifestyle.

Community based programs to improve the oral health of Australian Indigenous adolescents: a systematic review and recommendations to guide future strategies

BACKGROUND

To review the international literature on community-based interventions aiming to improve the oral health of Indigenous adolescents and identify which demonstrate a positive impact.

METHODS

Data sources were MEDLINE, EMBASE, CINAHL, SCOPUS, the COCHRANE library and the Australian Indigenous HealthInfoNet. Articles were included where they: were published in English from 1990 onwards; described oral health outcomes for Indigenous adolescents aged 10 to 19 years; implemented a community based oral health intervention. The Quality Assessment Tool for Quantitative Studies from the Effective Public Health Practice Project was applied.

RESULTS

Nine studies met inclusion criteria; two rated strong in quality; only one study was conducted with an urban community; five reported moderate community engagement. Five intervention strategies were identified, and schools were the most common setting reported. Statistically significant improvements were described in eight studies with the most frequently reported outcome being change in decayed missing or filled teeth.

CONCLUSIONS

Few good quality peer reviewed international studies of community-based oral health interventions which address the needs of Indigenous adolescents exist. Studies must include strong Indigenous community leadership and governance at all stages of the research, adopt participatory action-based research approaches, and are required in urban communities.

Adolescents with worse levels of oral health literacy have more cavitated carious lesions

The aim of the present study was to investigate whether the ability to recognize and read oral health terms is associated with the number of teeth with cavitated carious lesions in adolescents. A population-based cross-sectional study was conducted involving a sample of 746 adolescents representative of students aged 15 to 19 years at the public and private school systems in a city in northeast Brazil. Two examiners who had undergone a training and calibration exercise (inter-examiner and intra-examiner Kappa coefficient: 0.87 to 0.93) performed the diagnosis of caries using the Nyvad Index and evaluated the level of OHL (BREALD-30) of the adolescents. The participants answered questions regarding their history of visits to the dentist and the parents/caregivers answered a questionnaire addressing socioeconomic characteristics. A directed acyclic graph was created to direct the selection of covariables for adjustments in the Poisson multiple regression analysis to test the association between dental caries and OHL (α = 5%). Cavitated carious lesions (codes 3 to 6 on the Nyvad index) were found in 41.6% of the adolescents. Only 29.4% had a high level of OHL (BREALD-30 scores between 23 and 30); 42.3% of the families belonged to the A-B social class and 93% of the adolescents had been to the dentist at least once in their lifetimes. In the multivariate analysis, adolescents with inadequate (PR: 1.69; 95% CI: 1.18–2.41; p = 0.004) and marginal (PR; 1.42; 95% CI: 1.01–1.99; p = 0.042) OHL and those in the lower social classes (C-D-E) (PR: 1.85; 95% CI: 1.39–2.47; p<0.001) had more teeth with cavitated carious lesions. In conclusion, adolescents aged 15 to 19 years with poorer levels of OHL had a larger number of teeth with cavitated carious lesions, independently of their socioeconomic status and history of visiting a dentist.

Saúde bucal na atenção primária à saúde: articulações entre o ensino e a estratégia de saúde da família

Resumo Introdução A saúde bucal na atenção primária à saúde, com profissionais da Odontologia aptos nesse campo de atuação, tem sido descrita como promissora estratégia para se promover saúde. Objetivo Identificar e descrever as articulações intersetoriais e suas contribuições para a formação do profissional em Odontologia e para a saúde bucal de crianças de um município paulista. Material e método Pesquisa de campo, do tipo transversal, de abordagem mista e de caráter intervencionista. Dados secundários foram obtidos dos prontuários e relatórios de estagiários em Odontologia. Foram realizados atendimentos odontológicos a 455 crianças da rede básica de ensino e oito entrevistas com os familiares das crianças faltosas aos atendimentos. Foi utilizada estatística descritiva, com frequência simples e porcentagem, e Análise de Conteúdo para os dados qualitativos. Resultado Verificou-se que 42% das crianças encontravam-se em situação de alto risco à doença cárie. Os traumas e medos, e o escasso conhecimento de higiene bucal das crianças e dos pais influenciaram negativamente no cuidado com a saúde bucal. No consultório odontológico, as fragilidades apontadas pelos familiares foram o despreparo profissional, que vão desde questões técnicas até formas de abordagem pessoal. Conclusão Conclui-se que a prática na atenção primária à saúde aproximou os universitários da realidade social e ampliou e diversificou os cenários de ensino-aprendizagem com maior tempo para educação em saúde. Contudo, há necessidade de mais pesquisas sobre as experiências curriculares efetivas nessa temática.
