IRRIGANTS IN ENDODONTICS: A LITERATURE REVIEW

Abstract

This article aims to present a review of the literature on irrigating solutions used in endodontic procedures, seeking to highlight the best option considering the results obtained. The research was conducted through a comprehensive literature review, consulting the PubMed, Scielo, and Cochrane Library databases, covering publications between 2014 and 2022. Among the most effective and safe irrigating solutions are sodium hypochlorite (NaOCl), ethylenediaminetetraacetic acid (EDTA), and chlorhexidine (CHX), with NaOCl and CHX being the most widely used in clinical practice. The administration of these solutions plays a crucial role in controlling the microbial agents present in the root canals, since it is not possible to completely sterilize this system. Despite the effectiveness of the solutions and techniques currently available, there are still limitations that motivate the continuous search for irrigating alternatives, in addition to improving knowledge about existing options, in order to optimize the results of endodontic treatments.
