Evaluation of Antimicrobial Efficacy and Postoperative Pain After Using Silver Nanoparticles and Chitosan Nanoparticles Against Enterococcus Faecalis and Candida Albicans Biofilm (An in Vitro - in Vivo Study)

(RHDIRB2017122004) (438)

Silver nanoparticles possess unique physicochemical and biological properties in addition to their antibacterial capabilities. Similarly, zinc oxide nanoparticles have demonstrated antibacterial effects against a wide range of bacteria, including heat and pressure resistant spores. Given these characteristics, it would be valuable to evaluate and compare a new irrigation solution containing nanosilver and nanozinc-oxide particles with sodium hypochlorite. Furthermore, Chitosan Nanoparticles are expected to exhibit enhanced antibacterial activity compared to regular-sized Chitosan due to their ability to penetrate and disrupt microbial cell membranes. Consequently, the current study aims to assess and compare the antibacterial activity of Silver Nanoparticles and Chitosan Nanoparticles, as well as their impact on post-operative pain.
