Resumen
El trabajo de investigación busca analizar a la irrigación ultrasónica pasiva como alternativa para la desinfección de conductos. La endodoncia es un conjunto de conocimientos integrados en la salud oral que busca como objetivo preservar la pieza dental afectada cumpliendo con un protocolo establecido que tiene como misión principal eliminar pulpa sea vital o necrótica según lo requiera el caso, esto se lleva a cabo realizando una correcta irrigación en el conducto dental. La irrigación ultrasónica pasiva acompañada del hipoclorito sódico cumple con la función de eliminar más residuos, gérmenes y tejido pulpar que a diferencia de las irrigaciones con jeringa convencional que suele no eliminar por completo el material bacteriano. El hipoclorito de sodio es más eficaz que el agua en la irrigación ultrasónica pasiva, dado que la activación ultrasónica potencia su efecto antibacteriano y patrones de flujo activos. El riego también debe eliminar la capa de frotis y los desechos de dentina que se producen después de la instrumentación del conducto radicular. La eficacia de riego depende de los mecanismos de trabajo del irrigante y la capacidad de traer el irrigante en contacto con esos elementos, materiales y estructuras dentro del sistema de canales, que deben eliminarse. La instrumentación mecánica reduce casi a la mitad las bacterias en el interior de los conductos, por lo que necesitamos irrigantes para eliminar los microorganismos de los lugares donde no llegan los instrumentos. La desinfección del sistema de conductos, empleando antimicrobianos y disolventes de tejido pulpar, es considerada una parte esencial en la preparación químico‐mecánica del mismo.
The research work look for to analyze passive ultrasonic irrigation as an alternative for the disinfection of canals, endodontics is a set of knowledge integrated in oral health that seeks to preserve the affected tooth by complying with an established protocol whose main mission is eliminate vital or necrotic pulp as required by the case, this is carried out by performing a correct irrigation in the dental canal; Passive ultrasonic irrigation accompanied by sodium hypochlorite fulfills the function of eliminating more residues, germs and pulp tissue than conventional syringe irrigations, which usually do not completely eliminate bacterial material. Sodium hypochlorite is more effective than water in passive ultrasonic irrigation, since ultrasonic activation enhances its antibacterial effect and active flow patterns. Irrigation should also remove the smear layer and dentin debris that occurs after root canal instrumentation. Irrigation efficiency depends on the working mechanisms of the irrigant and the ability to bring the irrigant into contact with those elements, materials and structures within the canal system, which must be removed. Mechanical instrumentation reduces the bacteria inside the canals by almost half, for what is needed irrigants to eliminate microorganisms from places where the instruments do not reach. Disinfection of the root canal system, using antimicrobials and pulp tissue solvents, is considered an essential part of its chemical-mechanical preparation.
