Ozone application with the Ozonytron XL device
DeviceAn ozone generator (Ozonytron; Bionix, Munchen, Germany) with an KPX probe (CA Probe; Ozonytron, Bionix, Munchen, Germany) was used for OT. Topical gaseous ozone was applied into the periodontal pocket twice a week for 2 weeks based on the manufacturer's instructions. Ozone applications were at 75% power for 30 seconds (75 µg/ml). Ozone applications were performed by an experienced investigator. Ozone applications in the control side were simulated without starting the ozone generator
