Abstract

AbstractAimThis meta‐analysis aimed to compare the antibacterial efficacy of chitosan/chitosan nanoparticles (Ch/Ch‐NPs) versus sodium hypochlorite/chlorhexidine (NaOCl/CHX).Materials and MethodsA search was performed in four electronic databases until December 08, 2023. Studies with missing, unclear, and insufficient data sets were excluded. The included studies were assessed by two independent reviewers using the Joanna Briggs Institute Critical Appraisal Checklist for Quasi‐Experimental Studies. The meta‐analysis of standardized mean difference was performed using a random effects model. Additionally, funnel plots as well as Egger's regression intercept test were used to evaluate potential publication bias.ResultsA total of 426 samples were used in nine included studies. There was no difference in antibacterial efficacy between Ch/Ch‐NPs‐NaOCl (SMD: 0.005; 95% CI: −0.844–0.854; p = 0.990). However, the antibacterial efficacy of NaOCl was statistically more effective than Ch/Ch‐NPs (SMD: 0.807; 95% CI: 0.015–1.599; p = 0.046) using the bacterial culture method, and Ch/Ch‐NPs was statistically higher than NaOCl (SMD: −1.827; 95% CI: −2.720, −0.934; p < 0.000) using confocal laser scanning microscopy.ConclusionsCh/Ch‐NPs may be an alternative to NaOCl against Enterococcus faecalis. The methods used in the in vitro studies evaluating the antibacterial efficacy of irrigation solutions against E. faecalis may have had an impact on the results.
