Abstract
Disinfection was investigated in high-density ozone produced by dielectric barrier discharge under atmospheric pressure. Disinfection was studied on three-dimensional carriers made of hydrophilic vinyl-polysiloxane impression material and granular acrylic resin used for oral surgery. Experimental results indicate disinfection of spore-forming bacteria: Geobacillus stearothermophilus and Bacillus atrophaeus , and selected species of opportunistic pathogens: Aspergillus niger , Pseudomonas aeruginosa , Escherichia coli , Staphylococcus aureus , and Candida albicans .
