Antibacterial Effect of Gaseous Ozone In Infected Root Canal. In-Vivo Study

The irrigation is a central role in endodontic treatment. The aim of this clinical study was: to determine the anti-bacterial effect of gaseous ozone, combined with 0.9% NaCl, 2.5% NaOCl and 2% CHX, in an infected root canal. The research was performed in the University Dentistry Clinical Centre of Kosovo, respectively in the Department of Endodontic and Dental Pathology, Prishtina, Kosovo. In this research were included 40 patients of both genders, in age between 15-65 years. The sample selection was random. Upon taking theanamnesis and diagnosing for each patient, radiography was taken of the suspected retroalveolar tooth. To disinfect the root canal, the following irrigants were used: 2.5% NaOCl (Sodium Hypochlorite Solution, Sigma Aldrich-Germany), 2% CHX (Chlorhexidine Digluconate Solution, Sigma Aldrich-Spain) and gaseous ozone (Prozone WH, Austria). The study only included patients diagnosed with Parodontitis apicalischronica and Necrosis pulpae. The Kruskall-Vallis test, X-test, DF=3, r<0.01 showed that exists the significance difference in the isolated average number of the aerobe and anaerobe bacteria colonies, when gaseous ozone was used. In treating the infected root canal with gaseous ozone, combined with irrigants 0.9%, 2.5% NaOCl and 2% CHX, reduce the number of colonies of aerobic and anaerobic bacteria.
