Effectiveness of the adjunctive use of ozone and chlorhexidine in patients with chronic periodontitis

BACKGROUND: Scaling and root planning (SRP) is the gold standard approach for treatment of chronic periodontitis but used alone it may not be effective in removing periodontal pathogens from sites where access is poor. OBJECTIVE: To evaluate and compare the clinical and microbiological efficacy of ozone and chlorhexidine (CHX) as an adjunct to SRP in patients with chronic periodontitis. METHODS: (Pg). RESULTS: Both groups demonstrated significant intragroup reduction in PI, GI, PD, CAL, Pg count and Aa count from baseline to 3 months follow-up. There were no significant differences between two groups for any of the parameters. CONCLUSION: Ozonated olive oil can be used as an adjunctive subgingival irrigant in patients with chronic periodontitis.
