Resumen

El éxito del tratamiento endodóntico va a depender de la limpieza y la conformación del sistema de conductos radiculares. En la práctica clínica el uso de irrigantes provee una desinfección química de los conductos radiculares y remoción del barrillo atrapado en el interior del conducto gracias a la acción eficiente de las soluciones quelantes. El propósito de este estudio fue calcular la eficacia de la eliminación del barrillo dentinario en el tercio apical, con la utilización de EDTA al 17% y Ácido cítrico al 10% activando con diferentes dispositivos y técnicas como son la irrigación ultrasónica pasiva (PUI) y las puntas EDDY (ED). Se utilizaron 45 dientes premolares divididas aleatoriamente en cinco grupos: 4 grupos experimentales (n=10) y 1 grupo control (n=5). En cada raíz se preparó dos surcos longitudinales en vestibular y lingual, las cuales fueron recubiertas con oro para su observación bajo el microscopio electrónico de barrido para de este modo cuantificar los tubulos dentinarios abierto. Para el análisis estadístico se usó la prueba de Shapiro-Wilk,  Kruskal-Wallis y una comparación multiple con U Mann-Whitney las cuales demostraron que la activación con EDDY ha tenido los puntajes más bajos del experimento con una diferencia de 8 puntos con respecto de PUI con EDTA al 17% y una diferencia con PUI de 13 puntos con Acido cítrico al 10% en el tercio apical. No obstante, ninguno de los grupos experimentales fue capaz de remover todo el barrillo dentinario en el tercio apical, pero si presentaron diferencias significativas con respecto al grupo control, por lo que se recomienda el uso de soluciones quelantes y sistema de activación para poder obtener mejor índice de limpieza y asegurar un éxito tratamiento de conducto.
