Disinfection – effect of O3 on bacteria
Ozone therapy is used to describe procedures that use the gas ozone (a triatomic oxygen module, O3). The germ-killing and disinfecting effect of ozone has been scientifically proven. What is the effect of ozone on bacteria from a scientific point of view?
Ozone (O3) is a natural part of air but it does not occur in the same concentration as oxygen (O2 which constitutes 21% of the volume of air. Literature identifies the bactericidal effect of ozone as being at 1.5 – 4.9 ppm, therefore lying 15 to 49 X over the MAC value (maximum allowable concentration). The empirically determined time for the elimination of bacterial colonies, however, is only 6 to 24 seconds, i.e. significantly below the MAC limit. Prozone produces 140 ppm/2 litres.
Effect of ozone on bacteria
- Surface on biofilm
- Extensively on bacteria infiltrations, the microcirculation, the local immune defence
- Very extensively, lymph drainage, nerval supply, local immune defence
Effect of ozone on hard tissue (e.g. teeth)
The ozone gas also penetrates through the mucous membrane into the subepithelial tissue and attacks the germs that are there within a few seconds. While the atomic oxygen that has been released as a result of the breakdown of the ozone binds to the proteins in the bacterial cell membranes, the rest of the molecular oxygen remains. The molecular oxygen (O2) is used by the cells.
