Los microorganismos son factores etiológicos fundamentales en enfermedades pulpares y periapicales. Enterococcus faecalis, un coco Gram-positivo anaerobio facultativo, puede penetrar túbulos dentinarios y sobrevivir a la instrumentación químico-mecánica. El éxito endodóntico requiere irrigación efectiva para alcanzar áreas inaccesibles a los instrumentos. A pesar de la eficacia antimicrobiana del hipoclorito de sodio, su toxicidad requiere explorar alternativas. Evaluar la eficacia antimicrobiana de Smear Clear® contra E. faecalis. Este estudio in vitro evaluó Smear Clear® contra la cepa E. faecalis (ATCC 29212®), determinando su eficacia antimicrobiana y estableciendo concentraciones mínimas inhibitorias y bactericidas mediante técnicas de microdilución en microplacas con controles apropiados. Smear Clear® al 100% mostró actividad bactericida contra E. faecalis. Al 50% demostró ser la concentración mínima necesaria para inhibir el crecimiento con propiedades bacteriostáticas. Smear Clear® exhibe propiedades antimicrobianas contra E. faecalis y representa una alternativa potencial al hipoclorito de sodio en irrigación endodóntica, con componentes, particularmente cetrimida, que afectan directamente la sensibilidad bacteriana.
