RESUMEN
Introducción: El tratamiento de conducto tiene como uno de sus objetivos eliminar o al menos reducir el número de microorganismos presentes. El agente quelante más usado es el ácido etilendiaminotetraacético (EDTA) al 17% para eliminar el barrillo dentinario de las paredes del conducto radicular con poco efecto sobre los tejidos periapicales. Objetivo: analizar la eficacia de las soluciones quelantes sobre el tejido dentinario durante la limpieza y conformación del conducto. Esta investigación busca dar a conocer la importancia de la remoción del barrillo dentinario y su método de eliminación mediante soluciones quelantes. Materiales y métodos: El diseño de este trabajo es bibliográfico debido a que se recopiló información actualizada mediante metabuscadores como Pubmed, Scielo, Google Scholar, obteniendo información de diferentes artículos, revistas, libros y tesis. Seleccionando publicaciones dentro de los últimos 5 a 10 años, aunque también se consideraron fuentes fuera de este rango de tiempo. Conclusión: La mayoría de los trabajos refieren que la eliminación del smear layer no es completa en todo el trayecto del conducto radicular, los tercios coronal y medio del conducto radicular registran excelentes resultados con la mayoría de los quelantes, sin embargo, la porción apical del conducto radicular demostró un menor grado de eficiencia para la remoción del lodillo dentinario entre un quelante y otro, pero para mejorar la limpieza en el tercio apical se debe extender el tiempo de exposición y la concentración del agente quelante lo que provocaría una erosión mayor de la dentina.
ABSTRACT Introduction: Root canal treatment has as one of its objectives to eliminate or at least reduce the number of microorganisms present. The most commonly used chelating agent is 17% ethylenediaminetetraacetic acid (EDTA) to eliminate smear from the walls of the root canal with little effect on periapical tissues. Objective: to analyze the efficacy of chelating solutions on dentin tissue during canal cleaning and shaping. This research aims to show the importance of smear smear removal and its elimination method by means of chelating solutions. Materials and methods: The design of this work is bibliographic because updated information was collected through meta-search engines such as Pubmed, Scielo, Google Scholar, obtaining information from different articles, journals, books and theses. Selecting publications within the last 5 to 10 years, although sources outside this time range were also considered. Conclusion: Most of the works refer that the removal of the smear layer is not complete along the entire root canal, the coronal and middle thirds of the root canal register excellent results with most of the chelators, however, the apical portion of the root canal showed a lower degree of efficiency for the removal of the dentin slime between one chelator and another, but to improve the cleaning in the apical third, the exposure time and concentration of the chelating agent should be extended which would cause a greater erosion of the dentin.
