College of Dentistry discussed M.Sc. Thesis entitled “Cytotoxicity and Antibacterial Effectiveness of Two Concentrations of Chitosan Nanoparticles Integrated with Different Root Canal Irrigants (An In Vitro Study)”, on Sunday, 25 July 2025 forwarded by Sara Falah Ali. The study aimed at evaluating and comparing the cytotoxicity and antibacterial effectiveness of two concentrations of chitosan nanoparticles after integrating them with different root canal irrigants. The study sought to utilize nano-chitosan as an antibacterial agent and reduce the cytotoxicity of sodium hypochlorite and chlorhexidine when mixed with them. The study concluded that chitosan nanoparticles can improve cytotoxicity of 5.25% sodium hypochlorite and 2% chlorhexidine when they mixed together with synergistic antimicrobial activity when nano chitosan irrigation solution (0.2%, 0.5%) was mixed with 5.25% NaOCl and 2% chlorhexidine.
