Métodos auxiliares de desinfecção do sistema de canais radiculares

Abstract

The endodontic treatment aims to eliminate as many microorganisms and their by- products from the root canal system (RoS) as possible. In this sense, a combination of techniques such as aseptic treatment, chemical-mechanical preparation, antimicrobial irrigation solutions and intracanal medications are used in endodontics in order to achieve the goal of therapy. However, it is known that no current protocol is able to completely eliminate microorganisms from within the canal to make it 100% free of microorganisms. Several studies have shown that even after instrumentation, difficult to reach areas of the root canal remain untouched by instruments, thus exalting the importance of using adjuvant methods to minimize canal contamination. The aim of this study was to compare, by means of literature review, the different adjuvant techniques used in the optimization of root canal system disinfection. The methodology used was the search for articles in the SCIELO, PUBMED, and GOOGLE ACADEMIC databases, between the years 2001 and 2021, emphasizing the coadjuvant methods of root canal system disinfection, such as Chlorhexidine irrigation, passive ultrasonic irrigation, Photodynamic Therapy, and the XP-endo finisher. The results showed that all the studied adjuvant methods have been considered effective for the disinfection of the root canal system, however, none of them can leave the canals totally free of microorganisms.
