Summary

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

Conditions

• Dimensional Changes

Interventions

Type	Name	Description
OTHER	Alginate mixed with distilled water	Alginate will be mixed with distilled water only, without any disinfectant additive, to serve as the control for comparison
OTHER	0.2% Chlorhexidine + Alginate	Alginate will be mixed with 0.2% Chlorhexidine solution to evaluate its effect on the linear dimensional stability of alginate impressions
OTHER	1% Chitosan + Alginate	Alginate will be mixed with 1% Chitosan solution to assess its influence on the linear dimensional stability of alginate impressions
OTHER	0.2% Silver Nitrate + Alginate	Alginate will be mixed with 0.2% Silver Nitrate solution to determine its effect on the dimensional stability of alginate impressions
OTHER	Green-synthesized Silver Nanoparticles + Alginate	Alginate will be mixed with a solution of green-synthesized Silver Nanoparticles to investigate its effect on the dimensional stability of alginate impressions
OTHER	15% Povidone-Iodine + Alginate	Alginate will be mixed with 15% Povidone-Iodine solution to analyze its influence on the dimensional stability of alginate impressions
