Resumen
Los fundamentos acerca de la enfermedad pulpar y la muerte final de la pulpa dentaria se encuentran en la ciencia de la microbiología. Los clínicos deben conocer el efecto y la causa de la invasión bacteriana del espacio pulpar, lo que ocurre a las bacterias cuando se administra tratamiento, y las consecuencias finales cuando este concluye. La pulpa puede sufrir daño irreversible sea cual sea el mecanismo de acceso de las bacterias de la flora bucal normal a la pulpa, es decir, por caries dental, microfiltracion o fractura de la superficie radicular. Asimismo, una vez que ocurre la invasión bacteriana de los tejidos pulpares, es inmenso el número de factores relacionados con el huésped que se desarrollan tanto en la pulpa como en los tejidos perirradiculares. Una profunda desinfección del sistema de conductos es considerado el requisito clave para el éxito del tratamiento de conductos. Aunque esto puede conseguirse mediante la limpieza químico-mecánica es posible conformar y limpiar los conductos radiculares en su totalidad por lo complicada naturaleza de los mismos. Aun con el uso de instrumentación rotatoria, los instrumentos disponibles en la actualidad solo actúan en la parte central de los conductos dejando aletas e istmos sin haber sido tocados después de la completa preparación de los mismos. Es por eso que la preparación mecánica debe ser combinada con una adecuada irrigación, ya que esta última permite limpiar más allá de lo alcanzado únicamente con la instrumentación. A través de la historia de la endodoncia se han hecho continuos esfuerzos para desarrollar sistemas más efectivos para llevar y agitar el irrigante en los conductos radiculares. Vamos a conocer que bacterias patógenas existen en los conductos radiculares como se forman y se desenvuelven en la pulpa dentaria, y de que agente químico va a eliminar estas bacterias y todo residuo, barrillo dentinario que se lleva a cabo mediante la instrumentación de un tratamiento endodóntico. Por ese motivo el propósito de este artículo es presentar una revisión de los métodos de irrigación disponibles en la actualidad en Endodoncia.
The basics about the pulp disease and eventual death of the pulp found in the science of microbiology. Clinicians should know the effect and cause of bacterial invasion of the pulp space, what happens to bacteria when treatment is administered, and the ultimate consequences when this ends. The flesh can suffer irreversible damage whatever the access mechanism of the bacteria of the normal oral flora to the pulp, ie, for dental caries, microfiltration or fracture of the root surface. Also, once it happens bacterial invasion of the pulp tissue, is immense number of host-related factors that develop in the pulp and periradicular tissues. A thorough disinfection of the duct system is considered the key requirement for successful root canal treatment. Although this can be achieved by chemical-mechanical cleaning is possible to shape and clean the root canal in its entirety so complicated nature thereof. Even with the use of rotary instruments, instruments currently available only act in the central part of the fins and isthmuses leaving ducts without being touched after complete preparation thereof. That's why mechanical preparation must be combined with adequate irrigation, since the latter allows cleaning beyond what has been achieved only with instrumentation. Through the history of endodontics have made continuous efforts to develop more effective systems for carrying and waving the irrigant in the root canal. We will know that pathogenic bacteria exist in root canals as are formed and operate in the dental pulp and that chemical will remove these bacteria and any debris, smear layer that takes place through the implementation of an endodontic treatment . That is why the purpose of this article is to present a review of irrigation methods currently available in Endodontics.
