Saliva is essential for maintaining oral health, and conditions like hyposalivation increase the risk of diseases. To address this, artificial saliva (AS) formulations incorporated with antimicrobials have been proposed. This study aimed to evaluate the antimicrobial activity and determine the minimum inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of AS formulations containing nystatin (Nys), chlorhexidine diacetate 98% (Chx), and silver nanoparticles (AgNp) against Candida albicans biofilm. The fungistatic and fungicidal properties of six groups (AS; AS + AgNp 2 mM; AS + AgNp 4 mM; AS + AgNp 6 mM; AS + Nys; AS + Chx) were assessed using the XTT colorimetric assay. Additionally, 35 denture base heat-polymerized acrylic resin specimens were prepared and treated with the antimicrobials, serving as substrates for C. albicans biofilm development over 3, 6, and 12 h. Biofilm growth was quantified by CFU/mL counting. All analyses were performed with a significance level of p p C. albicans biofilm.
