Resumen

Objetivo: Este estudio experimental in vitro tuvo como objetivo comparar la desinfección del sistema de conductos radiculares de los dientes primarios, utilizando los sistemas rotativo y reciprocante. Metodología: Cuarenta y ocho conductos radiculares de veinticuatro dientes molares primarios se contaminaron con la cepa estándar de Enterococcus faecalis y se dividieron aleatoriamente en 4 grupos (n = 12). El Grupo PN comprendía los conductos radiculares preparados con el sistema rotativo ProTaperTM Next. El Grupo WOG se definió mediante el uso del sistema alternativo WaveOneTM Gold. Los archivos de los dos sistemas se procesaron termo-mecánicamente. El Grupo PU usó el sistema ProTaperTM Universal, sin tratamiento térmico, y el Grupo C (control negativo) no recibió tratamiento. Las muestras del conducto radicular se recogieron con puntas de papel estériles antes y después de su preparación, se diluyeron y se distribuyeron en placas con agar para Infusión Cerebro y Corazón (BHI). Se contaron las colonias bacterianas y los resultados se analizaron estadísticamente mediante las pruebas de Wilcoxon y Kruskal-Wallis (Dunn). Resultados: Hubo una reducción bacteriana significativa en los sistemas (p> 0.01). Sin embargo, no hubo diferencias significativas entre ellos (p <0.05) (PN = 3.38; WOG = 3.85; PU = 3.26). Conclusión: Ambos sistemas (rotativo y reciprocante) proporcionan desinfección en el sistema de conducto radicular de los dientes molares primarios.
