Antimicrobial and Antifungal effects of tissue conditioners containing a photocatalyst
Aim: This study evaluates the Antimicrobial and Antifungal ability of a tissue conditioner containing a photocatalyst for Streptococcus mutans, Staphylococcus aureus and Candida albicans.
Methodology: The photocatalyst was mixed with tissue conditioners powders at concentrations of 20wt%. Test specimens were made by mixing the tissue conditioner powders containing a photocatalyst mixed with liquid. All the specimens were then inoculated with media containing Streptococcus mutans, Staphylococcus aureus and Candida albicans separately, were irradiated by ultraviolet light for 4 hours. Antimicrobial and Antifungal effects were evaluated by counting the Colony forming unit (CFU).
Results: Tissue conditioners containing photocatalyst but not subjected to U V radiation showed reduction in the CFU values of 152x102 CFU/ml for streptococcus mutans, 164x102 CFU/ml for staphylococcus aureus and 154x102 CFU/ml for candida albicans. Tissue conditioners containing photocatalyst subjected to U V radiation show reduction in the CFU values of 97x102 CFU/ml for streptococcus mutans, 84x102 CFU/ml for staphylococcus aureus and 128x102 for Candida albicans.
Conclusion: Tissue conditioners containing photocatalyst irradiated with ultraviolet light controlled both bacterial and fungal growth.
