Ozone Therapy After Open Flap Debridement in Periodontitis

簡要摘要

Periodontitis is a chronic inflammatory disease characterized by the destruction of supporting periodontal tissues. Open flap debridement (OFD) is a commonly used surgical approach for the treatment of deep periodontal pockets when non-surgical therapy is insufficient. However, complete elimination of pathogenic microorganisms remains challenging. Ozone therapy has been proposed as an adjunctive treatment due to its antimicrobial, anti-inflammatory, and wound healing properties. This randomized split-mouth clinical trial aims to evaluate the clinical effectiveness of adjunctive ozone therapy in patients with Stage III periodontitis undergoing OFD. A total of 24 systemically healthy patients diagnosed with Stage III periodontitis were included in the study. In each patient, one side was randomly assigned to receive OFD combined with ozone therapy (test group), while the contralateral side received OFD alone (control group). Clinical periodontal parameters, including plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL), were recorded at baseline and at 6 and 12 months after treatment. The study aims to determine whether adjunctive ozone therapy improves clinical outcomes compared to conventional OFD alone.
