Analysis of bactericidal effects of sodium hypochlorite and chlorhexidine on resistantbiofilm microorganisms (E. Faecalis, C. Albicans).

Aim. To analyze current data on the bactericidal efficacy of endodontic irrigants, in particular, sodium hypochlorite and chlorhexidine in different concentrations relative to the elimination of resistant microorganisms (E. Faecalis, C. Albicans). Irrigation is an important stage in the treatment of root canals, it prevents the further contamination of the canals with microorganisms. However, irrigants do not always cope with this function, which leads to the occurrence of a secondary infection.Materials and methods. The study of publications was produced in the electronic databases such as Google Scholar, PubMed and ScienceDirect in the course of a systematic review of the literature. Included articles contain information about various types of irrigants and their antimicrobial effect.Results. 73 articles were viewed during the review. After analyzing the literature for inclusion criteria, the total number of publications has become 41.Conclusions. According to literature data, irrigation solutions in widely used by clinicians concentrations (sodium hypochlorite 3%, chlorhexidine 2%) are not able to completely eliminate E. faecalis and C. albicans from the root canal system
