Does the size matter? Evaluation of effect of incorporation of silver nanoparticles of varying particle size on the antimicrobial activity and properties of irreversible hydrocolloid impression material

Irreversible hydrocolloid impression materials are widely used in dentistry to record preliminary impressions of dentulous and partially dentulous mouths. Traditionally, it is supplied as a powder comprising soluble alginate, calcium sulfate and sodium phosphate as primary reactive ingredients along with diatomaceous earth as filler. Upon mixing with water, gelation reaction occurs between soluble alginate and calcium sulfate leading to the formation of calcium alginate gel [1 –3].
