| Popis: | Objective The radical anion of oxygen (O − ) is extremely oxidative and shows high reactivity. In this study, the antibacterial activity of water super-oxidised water containing high concentration of O − (O − -water) was tested against cultured planktonic cells of cariogenic bacteria, periodontopathic bacteria and Candida albicans . Methods O − -water was prepared using the AOE-750 (Oxy Japan Corporation, Japan) and its antibacterial activity against pure culture of Streptococcus sobrinus , Porphyromonas gingivalis , Prevotella intermedia , Aggregatibacter actinomycetemcomitans , Fusobacterium nucleatum and C. albicans evaluated. Each oral microorganism (10 4 to 10 8 CFU/ml) was exposed to three concentrations of O − -water at room temperature or 37 °C for 15 s to 24 h. Results Exposure to O − -water resulted in a bactericidal effect against all cariogenic and periodontopathic bacteria tested. No significant fungicidal effect was observed on C. albicans , however. Conclusion The results demonstrate that O − -water exerts an antibacterial effect on cariogenic and periodontopathic bacteria. |
