La apicectomía es un procedimiento indicado para el tratamiento de lesiones y periodontitis apical persistente después de un tratamiento de conductos; el procedimiento consiste en la eliminación de los últimos 3 mm apicales y posterior creación de una preparación para finalmente sellarlo con un material de obturación. Se ha reportado que los materiales biocerámicos (MTA-Gris, MTA-Blanco y Biodentine) tienen propiedades antibacterianas adecuadas. El objetivo de este estudio es evaluar la capacidad de colonización y formación de biofilm de E. faecalis sobre la superficie de materiales biocerámicos in vitro. Se emplearon 180 discos de dentina aleatorizados en 3 grupos experimentales (G-MTA+E. faecalis, W-MTA E. faecalis y Biodentine+E. faecalis) y 3 grupos control (G-MTA, W-MTA y Biodentine), El área/superficie cubierta por biofilm y microorganismos fue evaluada mediante SEM. Todas las muestras de los grupos experimentales mostraron una superficie rugosa e irregular debido a la colonización de microorganismos y la formación de biopelículas. El grupo de MTA-Gris mostró mejores propiedades antimicrobianas que MTA-Blanco y Biodentine. La eliminación y extirpación completa de los tejidos periapicales dañados y contaminados durante el tratamiento quirúrgico es fundamental para el éxito a largo plazo.
