Adjunctive Ozone Therapy for Residual Periodontal Pockets

Brief Summary

Patients with residual periodontal pockets following non-surgical periodontal therapy remain at risk for disease progression and may require further periodontal surgery. Repeated scaling and root planing (SRP) is commonly used for residual pockets; however, complete elimination of periodontal pathogens is often difficult to achieve. Ozone therapy has antimicrobial, anti-inflammatory, and wound-healing properties that may improve periodontal treatment outcomes. The aim of this randomized controlled clinical trial is to clinically and microbiologically evaluate the adjunctive effects of gaseous ozone application during repeated SRP for residual periodontal pockets in patients undergoing periodontal maintenance therapy. Twenty-six patients diagnosed with stage III or IV periodontitis presenting with residual periodontal pockets ≥5 mm with bleeding on probing will be included. Residual pockets will be randomly assigned to either repeated SRP alone (control group) or repeated SRP combined with ozone application (test group). Clinical periodontal parameters and microbiological findings will be evaluated at baseline, 3 months, and 6 months after treatment.
