NCT07725393

Brief Summary

This randomized, triple-blind, placebo-controlled split-mouth clinical trial aims to evaluate the clinical and biochemical efficacy of subgingival pomegranate peel extract gel as an adjunct to scaling and root planing (SRP) in the treatment of Stage II-III periodontitis. Thirty-two participants diagnosed with Stage II-III periodontitis will receive SRP in all selected periodontal sites. Test sites will receive locally delivered pomegranate peel extract gel, while contralateral control sites will receive a placebo gel. Clinical periodontal parameters, including probing pocket depth (PPD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), bleeding on probing (BOP), and gingival crevicular fluid levels of matrix metalloproteinase-8 (MMP-8), will be assessed at baseline, 1 month, 3 months, and 6 months to evaluate whether adjunctive pomegranate peel extract gel improves periodontal healing compared with SRP alone.

Study Arms (2)

Pomegranate Peel Extract Gel

EXPERIMENTAL

Periodontal sites receive scaling and root planing followed by subgingival application of pomegranate peel extract gel.

Drug: Pomegranate Peel Extract Gel

Placebo Gel

PLACEBO COMPARATOR

Periodontal sites receive scaling and root planing followed by subgingival application of placebo gel with identical appearance and consistency.

Other: Placebo gel

Interventions

Locally delivered subgingival gel containing pomegranate peel extract administered after scaling and root planing.

Pomegranate Peel Extract Gel

Placebo gel without active ingredient, identical in appearance and consistency to the experimental gel, administered after scaling and root planing.

Placebo Gel

Eligibility Criteria

Age30 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Adults aged 30 to 60 years.
  • Systemically healthy individuals.
  • Diagnosis of Stage II or Stage III periodontitis according to the 2018 Classification of Periodontal and Peri-Implant Diseases and Conditions.
  • Presence of at least 20 natural teeth.
  • Presence of at least two non-adjacent periodontal pockets (≥5 mm) located in different quadrants suitable for split-mouth allocation.

  • Provision of written informed consent.

You may not qualify if:

  • Current smokers or users of any tobacco products.
  • Pregnant or lactating women.
  • Patients with systemic diseases known to affect periodontal status or wound healing (e.g., uncontrolled diabetes mellitus, immunodeficiency disorders, osteoporosis requiring antiresorptive therapy).
  • Use of systemic antibiotics, corticosteroids, immunosuppressive agents, or non-steroidal anti-inflammatory drugs within the previous 3 months.
  • Periodontal therapy received within the previous 6 months.
  • History of allergy or hypersensitivity to pomegranate or any component of the study materials.

Masking Details
Participants, clinical operators administering the intervention, investigators responsible for clinical evaluation and data analysis, and outcome assessors are blinded to treatment allocation. Test and placebo gels are identical in appearance, consistency, and packaging. Randomization codes are maintained by an independent investigator until completion of data analysis.

Intervention Model
PARALLEL
Model Details: This is a randomized, placebo-controlled, triple-blind split-mouth clinical trial. Each participant receives both interventions: pomegranate peel extract gel is applied to randomly assigned periodontal sites, while contralateral sites receive placebo gel after scaling and root planing. Randomization is performed at the site level within each participant.
