Resumen
La permeabilidad apical, es una técnica que mantiene esta porción del conducto libre de acumulo de dentritus mediante la recapitulación con una lima de pequeño calibre a través del foramen apical. Entre los beneficios que obtenemos al realizar la permeabilidad apical podemos mencionar que ayuda a mantener la anatomía original de los canales radiculares, además mantiene la permeabilidad, también ayuda a mantener el espacio para que entre el instrumento y junto con la irrigación ayuda a transportar detritus hacia coronal en el momento de la irrigación, limpiando y desobstruyendo así el conducto para dejarlo preparado para el siguiente instrumento de mayor calibre. También facilita el intercambio y libre circulación de los irrigantes, gracias a ello evita problemas en el proceso de la conformación de los canales radiculares como acumulación de dentritus en el tercio apical, obstrucciones y pérdidas de longitud de trabajo. Objetivo: Determinar cuáles son las ventajas y desventajas de la patencia apical mediante el uso de la lima de pasaje en el procedimiento de conformación del conducto radicular.Métodos: investigación exploratoria descriptiva de corte longitudinal. Resultados: El uso de la lima de pasaje para lograr la permeabilidad apical es de gran importancia en la preparación y conformación de los canales radiculares. Conclusiones: existen estudios con evidencia de las desventajas de utilizar la lima de pasaje para lograr la permeabilidad apical, una de las más mencionadas es la influencia de esta en el dolor pos tratamiento debido a que los irrigantes usados para eliminar restos de microorganismos son irritantes.
Apical patency is a technique that is maintained in the root canal free dentition by recapitulation with a file of small caliber through the apical foramen. Furthermore, apical patency can bring about many benefits on patients who undergo an endodontic treatment. First, apical patency allows to preserve the original anatomy of the root canals. Second, it mantains permeability. Third, it permits to maintain the biological space so that the instrument enters and together with irrigation, it helps to transport dentritus towards the coronal área; thus cleaning and unclogging the root canal to leave it ready for the next instrument of greater caliber. Last but not least it facilitates the exchange and free circulation of the irrigant since it avoids problems in the process of the conformation of the root canals as accumulation of dentritus in the third apical, obstructions and losses of work length. The objective of this study is to determine the advantages and disadvantages of apical patency through the use of the patency file in the procedure of shaping the root canal. The methodological design corresponds to exploratory descriptive investigation of longitudinal section. Findings suggest that the use of the patency file to achieve apical permeability is of great importance in the preparation and conformation of the root canals. In essence there are studies with evidence of the disadvantages of using the patency file to achieve apical patency, one of the most mentioned is the influence of this in post treatment pain because the irrigators used to remove traces of microorganisms are irritants.
