ABSTRACT

Objetivo: avaliar a efetividade dos selantes aplicados por estudantes do curso de graduação em Odontologia da Universidade do Sul de Santa Catarina (Unisul), Grande Florianópolis, após 6 meses da aplicação, e estimar a prevalência de cárie dos participantes. Sujeitos e método: estudo observacional descritivo com indivíduos das clínicas de Odontologia. A efetividade dos selantes oclusais foi avaliada por roteiro validado na literatura, e a prevalência de cárie, dicotomizada. Os dados foram analisados por estatística descritiva e as associações pelo teste Qui-Quadrado. Resultados: a taxa de resposta do estudo foi de 94,7% (n=18), 2/3 da amostra eram do sexo feminino (72,2% IC 95% 49,1;87,5), 60% dos pacientes recebiam 3 salários mínimos ou menos, maiores proporções de indivíduo tinham selados seus dentes há pelo menos 9 meses. Pouco menos de 2/3 da amostra receberam Fluroshield como material restaurador em seus dentes. Dentre os 57 dentes avaliados, 70,2% apresentavam retenção to-tal. Os dentes mais acometidos pela perda de retenção foram os segundos molares superiores (40%). Mais de 2/3 da amostra não apresentaram cárie (88,9% IC 95% 67,2; 96,9). O isolamento relativo foi o mais prevalente (72,2% IC 95% 49,1;87,5). Conclusão: sob a perspectiva das práticas dos estudantes de Odontologia, metade da amostra de pacientes apresentou alguma perda de retenção dos selantes, mesmo que um número maior de retenções totais e a ausência de recidiva de cárie tenham sido observados. Isso reflete a importância da relação professor-aluno no planejamento e na correta aplicação das técnicas de selamento por estudantes de Odontologia. (AU)


Objective: to evaluate the effectiveness of pit and fissure sealants applied by undergraduate dental students of the University of Southern Santa Catarina (Unisul), SC, Brazil, after 6 months, and to estimate the prevalence of caries in the participants. Subjects and method: observational and descriptive study with individuals from the dental clinics. The effectiveness of pit and fissure sealants was evaluated using a script validated in the literature, and the prevalence of caries was dichotomized. The data were analyzed by descriptive statistics and the associations were made using the chi-square test. Results: the response rate of the study was 94.7% (n=18), 2/3 of the sample consisted of women (72.2% 95%CI 49.1, 87.5), 60% of the patients received three Brazilian minimum wages or less, and a great portion of the participants had sealed their teeth at least 9 months earlier. A little under 2/3 of the sample received Fluroshield as restorative material for their teeth. Among the 57 teeth evaluated, 70.2% presented complete retention. The teeth most affected by loss of retention were maxillary left second molars (40%). More than 2/3 of the sample did not present dental caries (88.9% 95%CI, 67.2, 96.9). Relative isolation was the most prevalent (72.2% 95%CI 49.1, 87.5). Conclusion: from the perspective of the practices of dental students, half of the sample of patients presented some loss of sealant retention, despite the greater number of complete retentions and absence of recurrent caries. This reflects the importance of the teacher-student relationship in the planning and correct application of sealing techniques by dental students. (AU)

ABSTRACT

Clinical trials are normally performed with well-known brands of glass ionomer cement (GIC), but the cost of these materials is high for public healthcare in less-affluent communities. Given the need to research cheaper materials, it seems pertinent to investigate the retention rate of a low-cost GIC applied as atraumatic restorative treatment (ART) sealants in two centers in Brazil. Four hundred and thirty-seven 6-to-8-year-old schoolchildren were selected in two cities in Brazil. The children were randomly divided into two groups, according to the tested GIC applied in the first permanent molars. The retention rate was evaluated after 3, 6 and 12 months. Kaplan-Meier survival analysis and the log-rank test were performed. The variables were tested for association with sealant longevity, using logistic regression analyses (α = 5%). The retention rate of sealants after 12 months was 19.1%. The high-cost GIC brand presented a 2-fold-more-likely-to-survive rate than the low-cost brand (p < 0.001). Significant difference was also found between the cities where the treatments were performed, in that Barueri presented a higher sealant survival rate than Recife (p < 0.001). The retention rate of a low-cost GIC sealant brand was markedly lower than that of a well-known GIC sealant brand.

ABSTRACT

Este estudo apresenta o resultado de uma avaliação de custo-efetividade conduzida ao longo de um ensaio clínico controlado para avaliar a efetividade do selamento com ionômero de vidro modificado por resina (Vitremer, 3M ESPE) e da aplicação de verniz fluoretado (Duraphat, Col-gate) em superfícies oclusais de primeiros molares permanentes, em crianças de 6 a 8 anos (N = 268), segundo o risco de cárie (alto risco; baixo risco). As crianças foram examinadas semestralmente, ao longo de 24 meses, pelo mesmo dentista calibrado, após alocação em seis grupos: controle alto risco e baixo risco (educação em saúde bucal trimestral); verniz alto risco e baixo risco (educação em saúde bucal trimestral + aplicação semestral de verniz); e selante alto risco e baixo risco (educação em saúde bucal trimestral + única aplicação do selante). A análise mostrou que o selamento de primeiros molares permanentes em crianças de alto risco apresentou razão de C/E de R$ 225,21(US$ 119,80) por superfície oclusal salva, e razão incremental de C/E de R$ 203,71(US$ 108,36) por superfície oclusal adicional salva. Conclui-se que uma única aplicação de selante, em escolares de alto risco, foi a intervenção mais custo-efetiva.


This study presents the results of a cost-effectiveness analysis in a controlled clinical trial on the effectiveness of a modified glass ionomer resin sealant ( Vitremer, 3M ESPE) and the application of fluoride varnish (Duraphat, Colgate) on occlusal surfaces of first permanent molars in children 6-8 years of age (N = 268), according to caries risk (high versus low). Children were examined semiannually by the same calibrated dentist for 24 months after allocation in six groups: high and low risk controls (oral health education every three months); high and low risk with varnish (oral health education every three months + varnish biannually); and high and low risk with sealant (oral health education every three months + a single application of sealant). Economic analysis showed that sealing permanent first molars of high-risk schoolchildren showed a C/E ratio of US$ 119.80 per saved occlusal surface and an incremental C/E ratio of US$ 108.36 per additional saved occlusal surface. The study concluded that sealing permanent first molars of high-risk schoolchildren was the most cost-effective intervention.


En este estudio se presentan los resultados de una evaluación de costo-efectividad (C/E) durante un ensayo clínico controlado para evaluar la efectividad de la obturación con ionómero de vidrio modificado con resina (Vitremer, 3M ESPE) y la aplicación de barniz de flúor (Duraphat, Colgate) en las superficies oclusales de los primeros molares permanentes, para niños de 6-8 años (N = 268) de edad, de acuerdo con el riesgo de caries (alto riesgo-bajo riesgo). Los niños fueron examinados cada seis meses por el mismo dentista calibrado, durante 24 meses, después de haberle sido asignados seis grupos: control alto riesgo y bajo riesgo (educación de salud bucal cada tres meses); barniz alto riesgo y bajo riesgo (educación de salud bucal cada tres meses + barniz semestralmente); obturación alto riesgo y bajo riesgo (educación de salud bucal cada tres meses + una sola aplicación de ionómero de vidrio). El análisis económico mostró que la obturación de los primeros molares permanentes de escolares de alto riesgo presenta una relación C/E de US$ 119.80 de ahorro por superficie oclusal y una ratio C/E incremental de US$ 108.36 de ahorro adicional por superficie oclusal.
