The Disinfecting Action of Ozonated Water and of Hydrogen Peroxide/Silver Ions In Vitro

Abstract

An in-vitro comparison was made between the disinfecting action of ozonated water and hydrogen peroxide/silver ion preparations using the “Quantitative suspension” test and Pseudomonas aemginosa. No microorganisms could be detected immediately after contact between ozonated water and the pseudomonadeae. In the case of the peroxide preparation, however, its action corresponded to that of aqua bidestillata (control experiment) and no disinfection had taken place. The use of hydrogen peroxide preparations in dental units for microbiological and toxicological reasons should therefore be reconsidered.
