Resumo(s)
A aplicação de selantes de fissuras é uma medida de prevenção contra a cárie dentária. Actualmente, os dois tipos de materiais mais utilizados são os resinosos e os ionómeros de vidro, sendo estes últimos usados como uma alternativa aos anteriores. Objetivo: Realizar uma revisão sistemática baseada na evidência científica existente sobre a eficácia clínica dos selantes de ionómero de vidro comparativamente aos à base de Bis-GMA na prevenção da cárie dentária. Métodos: Foi efetuada uma pesquisa nas bases de dados eletrónicas primárias e secundárias: MEDLINE/Pubmed, Embase, CINAHL, LILACS, OvidSP e Cochrane Plus. Na estratégia de investigação foram utilizados como palavras-chave, os termos em inglês: “Pit and fissure sealants”[MeSH] AND (Bis-GMA OR resin OR composite OR glass-ionomer). Definiram-se como limites, os estudos clínicos controlados aleatorizados e quasi-aleatorizados, em indivíduos humanos, com idade inferior a 18 anos e com data de publicação entre 1 de Janeiro 1970 e 31 de Dezembro de 2011, inclusivé. Os estudos foram selecionados com base em critérios de inclusão e exclusão previamente definidos. Resultados: No presente trabalho foram incluídos apenas cinco estudos dos 282 encontrados, os quais cumpriram os critérios de pesquisa e apresentaram uma avaliação positiva no inquérito CASP. Na análise qualitativa dos estudos selecionados verificaram-se algumas falhas metodológicas dos mesmos, apresentando resultados heterogéneos e que não permitem uma comparação direta entre os estudos. Conclusão: Com a análise da evidência científica, constata-se não existir uma igual eficácia entre os selantes de ionómero de vidro e os resinosos, verificando-se uma tendência para um maior efeito preventivo contra a cárie dentária dos selantes à base de Bis-GMA. Contudo, consideram-se necessários mais ensaios clínicos de melhor qualidade de evidência científica e que avaliem populações com diferentes níveis de risco cariogénico, particularmente as de alto risco.
The use of pit and fissure sealants is a preventive measure against dental caries. Nowadays, two types of materials are commonly used: the resin-based sealants and glass ionomers cements, the latter one being used as an alternative to resin sealants. Objective: Elaborate a systematic review based on the scientific evidence concern the clinical effectiveness of glass ionomer sealants when compared with Bis- GMA sealants in terms of caries prevention. Methods: A research was developed over the following primary and secondary electronic data bases: MEDLINE/Pubmed, Embase, CINAHL, LILACS, OvidSP e Cochrane Plus. The search strategy was made using the English terms: “Pit and fissure sealants”[MeSH] AND (Bis-GMA OR resin OR composite OR glass-ionomer) and it was limited to randomized or quasi-randomized controlled trials done on humans, under 18 years old, over the articles published between 1st January 1970 and 31st December 2011, inclusive. Studies were selected using inclusion and exclusion criteria previously defined. Results: In this review a total of 282 articles were identified, 5 of which met both the research criteria and a positive result after the CASP quality assessment. During the selected studies’ qualitative evaluation, methodological flaws were identified, resulting in heterogenous results which do not allow a direct comparison between studies. Conclusion: The scientific evidence analysis showed there is not an equal efficacy between glass ionomer sealants and resin-based sealants, existing a trend to a higher preventive effect against dental caries on Bis-GMA-based sealants. However, further clinical trials with better quality of scientific evidence are needed. New studies should evaluate populations with different levels of caries risk, particularly those at high risk.
