Abstract:

Chitosan has inhibited the growth of many pathogenic bacteria and fungi. The tissue conditioners are suitable platforms for growth and colonization of a variety of micro-organisms. One way to inhibit the growth of microorganisms is the combination of it with anti-fungal and anti-bacterial materials. This study was conducted to evaluate the anti-bacterial and anti-fungal properties of adding nanoparticles of Ag, ZnO and chitosan to tissue conditioners. Four micro-organisms in six different concentrations of nanoparticles of Ag, ZnO and chitosan were evaluated at 24 and 48 hours which included a total of 288 samples. Complete inhibition of growth occurred in Candida albicans in concentration of 2.5% and in Enterococcus faecalis, Pseudomonas aeruginosa and Streptococcus mutans in concentration of 5% of Ag, ZnO and chitosan nanoparticles. Also, the best effective concentration of nanoparticles in both 24 hours and 48 hours in Candida albicans was 1.25% and Enterococcus faecalis, Pseudomonas aeruginosa and Streptococcus mutants was 2.5%. The combination of nanoparticles Ag, ZnO and chitosan helps to inhibit the growth of microorganisms in the tissue conditioners. Also, the power effect of these nanoparticles on the fungi is more than bacteria
