This quasi-experimental comparative study investigates the effects of incorporating various self-disinfecting agents-0.2% Chlorhexidine (CHX), 1% Chitosan solution, 0.2% Silver Nitrate (AgNO3), green-synthesized Silver Nanoparticles (AgNPs), and 15% PVP-Iodine-on the linear dimensional stability of dental alginate impressions. Alginate is widely used in dentistry but is prone to dimensional changes and contamination. This study aims to assess whether integrating these disinfectants can reduce microbial risks without compromising the material's dimensional accuracy, thereby improving infection control and the precision of dental prostheses
