Abstract
La irrigación es un paso indispensable en la desinfección del conducto radicular Con la que se pretende eliminar la capa residual, compuesta por restos orgánicos e inorgánicos, incluyendo microorganismos que podrían permanecer viables en su interior y ser la causa de reagudizaciones Está demostrado que la instrumentación rotatoria reduce el número de bacterias sólo en un 50%. Como consecuencia, se han empleado numerosos irrigantes a lo largo de los años para la desinfección del conducto radicular A día de hoy, no existe un irrigante que pueda efectuar por sí mismo una irrigación efectiva, por tanto se recurre a la combinación de irrigantes, utilizando uno como desinfectante y otro como quelante. Los más comunes son el hipoclorito sódico y el ácido etilendiaminotetraacético (EDTA). Existen zonas del sistema de conductos inaccesibles a la instrumentación, tanto manual como mecánica, por lo que además de los sistemas de irrigación convencionales, han surgido nuevos mecanismos del irrigación y agitación para que el irrigante alcance esas zonas El conocimiento de la flora bacteriana del interior de los conductos radiculares, ha contribuido a un aumento de la preocupación acerca de la capacidad de descontaminación de los mismos...
Irrigation is essential to root canal disinfection It is used to remove the residual layer, composed of organic and inorganic residues, including microorganisms that may remain viable in the interior and be the cause of exacerbations. It has been demonstrated that rotary instrumentation reduces the number of bacteria by only 50%. Consequently, we have used numerous irrigants along the years to disinfect the root canal. Today there is no irrigant that can perform effective irrigation on its own. Therefore, we resort to the combination of irrigants, using one as a disinfectant and another as a chelating agent. The most common are sodium hypochlorite and ethylenediaminetetraacetic acid (EDTA). Certain areas of the canal system are inaccessible for manual and mechanical instrumentation and as a result, in addition to conventional irrigation systems, new irrigation and agitation mechanisms have been conceived to help the irrigant reach said areas. Knowledge of the bacterial flora inside the root canals has increased concern about the ability to decontaminate them. Enterococcus is the bacterial species most frequently isolated in dental infection.Enterococcus faecalis is capable of surviving in very difficult environmental conditions, such as the root canal after endodontic treatment...
