Abstract
Purpose: analytical analysis and study of literature sources comparing irrigation solutions and their activation methods in routine endodontics.
Materials and methods: in the eLibrary database, PubMed, Google Scholar and Meduniver requested scientific articles using the keywords: root canal cleaning, sodium hypochlorite, chlorhexidine, ethylenediaminetetraacetic acid, root canal irrigation, activation of irrigation solutions. Thus, this article included 35 research papers on the topic of irrigation solutions and their activation.
Results: this analytical analysis and the study of literary sources have shown that one of the most important factors in the prevention and treatment of endodontic pathology is adequate cleaning and irrigation of the root canal, since in the vast majority of cases they have an irregular shape, numerous lateral, deltoid branches and anastomoses. Oval, dumbbell-shaped or C-shaped root canals are also quite common. In modern endodontics, dentists use sodium hypochlorite, ethylenediaminetetraacetic acid and chlorhexidine as irrigants on a daily basis.
Conclusion: based on the literature, it was revealed that one of the best disinfectant solutions for root canals today is sodium hypochlorite, however, it does not meet all the parameters of an ideal irrigant.
