Ozone-therapy in Non-surgical Periodontal Therapy

The test group received ozone therapy immediately after non-surgical treatment, at a fixed concentration of 2100 ppm and 80% oxygen, applied three times at the site. Ozone was delivered into the periodontal pocket using a sterile syringe with a flat tip. Ozone was generated with the Ozone DTA Ozone Generator (Denta Tec Dental AS, Norway), which was operated for 20 seconds in accordance with the manufacturer's instructions.
