Ozone Gel vs Chlorhexidine Gel as an add-on to non-surgical cleaning for smokers with Stage II periodontitis

Official title: Clinical and Biochemical Evaluation of Ozone Gel Versus Chlorohexidine Gel as an Adjunct to Non-Surgical Treatment of Stage II Periodontitis Grade B Among Smokers Patients

Run by October 6 University · NCT07923708 · Data updated 2026-11-12

This study tests whether Ozoral ozone gel or chlorhexidine gel added to standard non-surgical periodontal therapy can improve outcomes in smokers with Stage II Grade B periodontitis.

Is this trial a fit for you?

Likely a good fit

Adults aged 25-45 with Stage II Grade B periodontitis, including both smokers and non-smokers, who meet the inclusion criteria.

Probably not a fit

Patients with systemic diseases affecting periodontal health, recent periodontal therapy, or recent antibiotic/anti-inflammatory use may not experience additional benefit.

What this trial studies

This interventional study compares two adjunct gels used with standard scaling and root planing in smoker patients with Stage II Grade B periodontitis. Participants receive conventional periodontal cleaning alone, or with either chlorhexidine or ozone gel as an adjunct. The trial also includes a non-smoker comparator group with the same diagnosis to provide baseline context. Outcomes include clinical and biochemical measures of periodontal status to see if the gels offer additional benefit beyond standard therapy. The study builds on known antimicrobial and anti-inflammatory properties of chlorhexidine and ozone to assess real-world effectiveness in a smoker population.

Why it matters

Potential benefit: If successful, the adjunct gels could provide better reduction of periodontal inflammation and improved attachment levels for smokers with this condition.

How similar studies have gone: Previous work has shown antimicrobial and anti-inflammatory benefits of chlorhexidine and ozone gels in periodontal therapy, supporting potential benefit in this context.
