Green tea extract gel added to standard care for stage II periodontitis

Official title: Effectiveness of Epigallocatechin-3-Gallate (Green Tea Extract) as Adjunctive Locally Delivered Nanotherapeutic in the Treatment of Stage II Periodontitis (A Randomized Controlled Clinical Trial)Man

Run by Mansoura University · NCT07754253 · Data updated 2026-11-12

This study tests whether a green tea extract gel packaged in tiny particles, placed in gum pockets after cleaning, helps reduce pocket depth in people with stage II periodontitis.

Is this trial a fit for you?

Likely a good fit

Adults 25–60 with stage II periodontitis (pocket depth ≤ 5 mm, CAL 3–4 mm), good plaque control, and consent willing to participate.

Probably not a fit

Patients with active systemic disease, recent periodontal therapy, recent antibiotic/anti-inflammatory use, pregnancy, lactation, or smoking may not benefit from this intervention.

What this trial studies

This early-phase interventional trial investigates the local delivery of epigallocatechin-3-gallate (EGCG)–loaded chitosan nanoparticulate gel as an adjunct to scaling and root planing. Ten adults with stage II periodontitis will receive the EGCG gel into periodontal pockets in addition to standard debridement, with comparisons to debridement alone. Primary outcome is pocket depth reduction at 3 months; secondary outcomes include clinical attachment level, bleeding on probing, plaque, gingival indices, and gingival crevicular fluid TNF-α. The study explores biochemically relevant changes alongside clinical measures to assess anti-inflammatory and periodontal healing effects.

Why it matters

Potential benefit: If successful, participants may experience greater pocket depth reduction and improved periodontal health when EGCG gel is used with standard cleaning.

How similar studies have gone: Prior work in local antimicrobial and anti-inflammatory strategies for periodontitis supports potential benefit, but this exact EGCG-loaded nanoparticulate gel approach is novel in this setting.
