Efectividad del hipoclorito de sodio en sus diferentes concentraciones y su acción en el conducto radicular. Revisión bibliográfica.

Abstract

OBJECTIVE: To synthesize the literature on the effectiveness of sodium hypochlorite at different concentrations and its action in the root canal. INTRODUCTION: Sodium hypochlorite (NaClO) is the most commonly used irrigant in endodontics, and it is considered the gold standard for root canal irrigants due to its antibacterial properties and tissue-dissolving abilities. MATERIALS AND METHODS: A documentary study was conducted through a bibliographic review, analyzing 100 articles from scientific databases such as SciELO, Google Scholar, Redalyc, PubMed, Web of Science, and Elsevier. Seventy-five articles were excluded for not meeting the required criteria, leaving 25 articles for review. CONCLUSION: Based on the research reviewed, it was found that the action of sodium hypochlorite at concentrations ranging from 0.5% to 5.25% varies. Concentrations between 0.5% and 2% are preferred for their ability to dissolve the dentinal mud within the root canal and are less toxic. In contrast, concentrations ranging from 2.5% to 5.25% are chosen for their ability to dissolve both organic and inorganic tissue and their high antimicrobial effectiveness within the root canal system. Keywords: sodium hypochlorite, root canal irrigation, action.
