Resumen

Los nuevos cementos de silicato de calcio listos para usar (por ejemplo, Bio-C Sealer y Sealer Plus BC) han demostrado ser materiales bioactivos y biocompatibles. Sin embargo, su actividad antimicrobiana aún no se ha desvelado por completo. El objetivo de este estudio fue evaluar la actividad antimicrobiana de cementos biocerámicos (Bio-C Sealer, Sealer Plus BC y BioRoot RCS) en comparación con cementos a base de resina (AH Plus, Sealer Plus y MTA Fillapex). Los cementos frescos se probaron contra las biopelículas de Enterococcus faecalis utilizando pruebas de contacto directo e indirecto. Las unidades formadoras de colonias se contaron después de 24 horas. Además, se utilizó el ensayo de violeta cristal para evaluar los efectos de los extractos de cemento sobre la biomasa de biopelículas. Se utilizaron medidas de densidad óptica para cuantificar la biomasa. Los cementos biocerámicos mostraron una mayor actividad antimicrobiana que los cementos a base de resina cuando estuvieron en contacto directo con biopelículas (P < 0.05). Sealer Plus BC y Bio-C Sealer mostraron mayor actividad antimicrobiana que AH Plus en la prueba indirecta (P < 0.05), lo que sugiere una mayor difusión de estos materiales. La prueba de violeta cristal reveló que Sealer Plus BC fue el material más eficaz para reducir la masa de biofilm (P < 0.05) mostrando una diferencia significativa con otros cementos biocerámicos. Bio-C Sealer y Sealer Plus BC mostraron una mayor actividad antimicrobiana que AH Plus contra las biopelículas de E. faecalis en pruebas directas e indirectas. Además, Sealer Plus BC mostró el mejor efecto sobre la biomasa de biopelículas.
