摘要：We developed an effective and non-irritant mouthwash that is alcohol-free and has a low concentration of silver nanoparticles (SNP) in order to be used for preventing oral cavity infections in immunocompromised oncologic patients. We studied antimicrobial effects of silver nanoparticles (SNP) in the range of (50–0.024 µg/ml) and 3% of ethanol (30,000 µg/ml) in mouthwash. Antimicrobial effects of two treatments were studied by doing challenge test on microorganisms such as Streptococcus mutans, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and measuring MIC and MBC (MFC) values of SNP toward mentioned microorganisms. These values of SNP respectively were in the range of (0.78–3.12) and (1.56–12.5 µg/ml). Results showed that SNP in the MIC and the lower concentrations killed all of the used microorganisms. No difference was observed between the antimicrobial effect of ethanol-free mouthwash containing SNP and mouthwash containing SNP and ethanol (30,000 µg/ml). SNP has high antimicrobial effects at low concentrations and it can be a good alternative for ethanol (30,000 µg/ml) because ethanol is also irritating, especially to sensitive or inflamed mucosa
