Evaluación de eficacia de las limas Protaper, limas HERO SHAPER GOLD, ProTaper Universal limas de retratamiento y limas de retratamiento R-Endo con y sin uso de irrigación ultrasónica pasiva mediante lima Irrisafe para la eliminación de Gutapercha y Sellador AH plus de los conductos radiculares bajo el microscopio quirúrgico dental
Resumen
Antecedentes: El propósito del presente estudio es evaluar la eficacia de cuatro diferentes limas rotativas de NiTi, limas ProTaper, limas HERO SHAPER GOLD, limas de retratamiento ProTaper Universal y limas R-Endo para eliminar GP y sellador de los conductos radiculares con o sin uso de irrigación ultrasónica pasiva mediante lima Irrisafe bajo DOMS. La hipótesis de este estudio es que el uso de PUI podría dar como resultado una mejor limpieza de los conductos radiculares después de la instrumentación para la eliminación del GP y el sellador. Materiales y métodos: El presente estudio in vitro se realizó en el departamento de Odontología Conservadora y Endodoncia, G. Pulla. Facultad y hospital dental Reddy, Kurnool, Andhra Pradesh. Las muestras del estudio comprendieron 100 dientes anteriores maxilares humanos de raíz única extraídos y se recolectaron del Departamento de Cirugía Oral y Maxilofacial, G. Pulla Reddy Dental College & Hospital, Kurnool. Resultados: La prueba t muestra que hubo una diferencia estadísticamente significativa entre los Sub individuales grupos de los Grupos I,II y IV (p<0,05). Y no hubo diferencia estadísticamente significativa entre los subgrupos del grupo III (p>0,05), pero el porcentaje de GP restante y sellador en los conductos radiculares después del retratamiento fue comparativamente mayor en el subgrupo A que en el subgrupo B. Discusión: Bajo las condiciones experimentales, todos las limas de retratamiento dejaron cierta cantidad de GP y sellador en los conductos radiculares y no hubo diferencias significativas entre ellos. Sin embargo, R-Endo es mejor siguiendo el sistema de retratamiento ProTaper Universal, las limas Protaper y las limas HERO SHAPER GOLD. El uso adicional de irrigación ultrasónica pasiva con lima Irrisafe dio como resultado una mejor limpieza de la pared del conducto radicular después del retratamiento.
