Resumen

Objetivo: Este estudio evaluó la eliminación de bacterias en conductos radiculares achatados después de la preparación con diferentes conicidades de los instrumentos ProDesign Logic. Metodología: Cincuenta y cinco incisivos mandibulares con conductos radiculares achatados se contaminaron con un cultivo puro de Enterococcus faecalis ATCC 29212 durante 21 días a 37ºC. La preparación de los conductos radiculares se realizó utilizando ProDesign Logic y solución salina estéril al 0,9% para irrigación. Las muestras se asignaron aleatoriamente a tres grupos experimentales (n = 15) según la conicidad del instrumento utilizado: 25.03, 25.04 o 25.06. Se tomaron muestras bacteriológicas intracanal antes (S1) y después (S2) de la preparación y se calculó el número de unidades formadoras de colonias por mililitro (UFC/mL). Las diferencias en los recuentos bacterianos antes y después del tratamiento, dentro de cada grupo, se analizaron mediante la prueba t pareada. Los grupos se compararon mediante ANOVA con una prueba post hoc. El nivel de significancia se fijó en p <0,05. Resultados: Se confirmó la formación de biopelículas maduras en las paredes del conducto radicular mediante el microscopio electrónico de barrido. Las colonias bacterianas se redujeron significativamente en S2 en comparación con S1 en todos los grupos experimentales (p <0,001). No se observaron diferencias significativas entre los grupos con respecto al porcentaje de reducción bacteriana (p >0,05). Conclusión: La preparación de conductos radiculares achatados con instrumentos ProDesign Logic con conicidades de 0.03, 0.04 y 0.06 resultó en una reducción similar de la biopelícula planctónica y bacteriana. Ninguno de los instrumentos dejó los conductos radiculares completamente libres de bacterias.
