Resumo: | Purpose: To evaluate the in situ biofilm formation on enamel fragments restored with glass ionomer cement. Methods: Six volunteers wore removable intra-oral devices similar to orthodontic appliances, containing four fragments of bovine enamel restored with glass ionomer cement. A blind examiner visually analyzed the biofilm formation on enamel and glass ionomer cement specimens by using a standardized index after 24, 48, 96, and 168 hours (7 days). Results: No significant difference was detected between the biofilm formation on enamel and on glass ionomer cement. The results showed a faster biofilm development on specimens facing the palate, independently from the substrate. Conclusions: Glass ionomer cement did not affect microbial colonization. Biofilm development was higher where less oxygen was available. Key words: Biofilm; enamel; glass ionomer cement; in situ study |

Key words: Biofilm; enamel; glass ionomer cement; in situ studyObjetivo: Avaliar, in situ, o desenvolvimento de biofilme sobre fragmentos de esmalte bovino com restaurações de cimento de ionômero de vidro. Metodologia: Seis voluntários utilizaram um dispositivo intra-bucal removível, semelhante a um aparelho ortodôntico, contendo quatro espécimes de esmalte bovino restaurados com cimento de ionômero de vidro, posicionados para o meio bucal livre ou em contato com o palato. Um examinador cego analisou visualmente a formação de biofilme nos corpos-de-prova em esmalte e em ionômero de vidro utilizando um índice-padrão após 24, 48, 96 e 168 horas (7 dias). Resultados: Não houve diferença significativa na formação de biofilme sobre o ionômero de vidro em relação ao esmalte. Houve um desenvolvimento mais rápido do biofilme nos corpos-de-prova voltados para o palato, independentemente do tipo de substrato. Conclusões: O cimento de ionômero de vidro não afetou a colonização microbiana. O desenvolvimento de biofilme foi maior no local com menor disponibilidade de oxigênio.
