RESUMO Objetivos: avaliar, através de uma revisão da literatura, a eficácia antibacteriana in vitro de determinados materiais restauradores dentários sobre microrganismos envolvidos em processos cariosos, especialmente Streptococcus mutans. Material e Métodos: O levantamento bibliográfico foi realizado nas bases de dados Medline, PubMed, Scielo, Lilacs e Cochrane, aplicando-se os seguintes descritores: potencial antibacteriano, Streptococcus mutans, materiais restauradores, cimentos de ionômeros de vidro, compômeros, resinas compostas. Foram selecionados 8 artigos, com base nos seguintes critérios de inclusão: estudos in vitro que avaliaram a atividade antibacteriana de materiais restauradores e que utilizaram cepas da bactéria Streptococcus mutans em meios de cultura tradicionais, bem como disponibilidade do texto integral, publicação nas línguas portuguesa, inglesa ou espanhola e clareza no detalhamento metodológico utilizado. Resultados e Conclusão: Os resultados dos estudos selecionados demonstram que cimentos de ionômero de vidro apresentam maior potencial antibacteriano do que compômeros e resinas compostas, apesar da necessidade de mais estudos que esclareçam o real potencial antibacteriano desse material. DESCRITORES Produtos Com Ação Antimicrobiana. Streptococcus mutans. Materiais Dentários. Cimentos de Ionômeros de Vidro. Resinas Compostas. Compômeros. SUMMARY Objective: To evaluate, through a literature review, the in vitro antibacterial effect of restorative dental materials on microorganisms involved in dental caries such as Streptococcus mutans. Material and Methods: This literature review was conducted in the databases Medline, PubMed, Scielo, Lilacs and Cochrane, and the following descriptors were employed: antibacterial potential, Streptococcus mutans, restorative materials, glass ionomer cement, compomer e composite resins. Eight articles were selected based on the following inclusion criteria: in vitro studies that evaluated the antibacterial activity of restorative materials and used strains of Streptococcus mutans grown on traditional culture media, as well as availability of full text, publication in Portuguese, English or Spanish, and clarity in describing methodology details. Results and Conclusion: Data revealed that glass-ionomer cements presented a higher antibacterial activity than compomers and composite resins, despite the need for further studies in order to clarify the real antibacterial potential of such material. DESCRIPTORS Products With Antimicrobial Action. Streptococcus mutans. Dental Materials. Glass Ionomer Cements. Composite Resins, Compomers. http://periodicos.ufpb.br/ojs2/index.php/rbcs
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
