Active oxygen-releasing gel with light therapy for advanced gum disease
Official title: Evaluation of Active Oxygen Releasing Gel Combined With Photodynamic Therapy in The Treatment of Stage III Periodontitis (A Randomized Controlled Clinical Trial)
Run by Alexandria University · NCT07368699 · Data updated 2026-11-12
This test sees if adding an oxygen-releasing gel, with or without a light-based photodynamic therapy, to standard deep cleaning helps people with stage III periodontitis.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 30–70 with stage III periodontitis, residual periodontal pockets ≥4 mm and clinical attachment loss ≥5 mm, who are non-smokers and have not had periodontal treatment in the prior 3 months.
✕Probably not a fit
Smokers, people with systemic conditions that affect healing (such as diabetes), pregnant or lactating women, those who used antibiotics or anti-inflammatory drugs recently, and people with parafunctional habits are unlikely to benefit or are excluded.

What this trial studies
This randomized clinical trial will enroll 42 adults with stage III periodontitis and assign them to one of three groups: scaling and root planing (SRP) alone, SRP plus a topical active oxygen-releasing gel, or SRP plus the gel together with photodynamic therapy using a diode laser and photosensitizer. The oxygen-releasing gel is applied to the gums and is intended to reduce harmful bacteria by releasing oxygen locally, while photodynamic therapy uses a dye and light to target bacteria. Clinical outcomes such as pocket depth, clinical attachment levels, and gingival inflammation will be compared between groups over the study follow-up. Eligible participants are adults 30–70 years old, non-smokers, without systemic conditions that affect periodontal healing and without recent periodontal treatment or recent antibiotics/anti-inflammatories.
Why it matters
Potential benefit: If successful, adding the gel and photodynamic therapy could reduce pocket depth and gum inflammation beyond deep cleaning alone, helping preserve tooth support and oral health.
How similar studies have gone: Previous studies of photodynamic therapy as an adjunct to scaling and root planing have shown mixed but sometimes modest improvements, while active oxygen-releasing gels are a newer approach with limited published evidence.
