概要 We aimed to investigate the bactericidal and cleaning effects of ozone water on pathogenic bacteria associated with oral diseases (Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus mutant, and Porphyromonas gingivitis) under planktonic and biofilm growth conditions. When planktonic bacteria were exposed to 5-ppm ozone water, a remarkable antibacterial activity was observed against all of the tested bacterial species. Contrarilly, biofilms showed high resistance to zone water; the bacterial load only slightly applied at a low flow rate to the biofilms on polystyrene disks, the number of bacteria on the disks was significantly decreased. Our results have shown that continuous application of ozone water can eliminate oral disease-related bacteria even in biofilms.
