Gum fluid proteins may hold clues to periodontal disease severity
NCT ID NCT07793370
First seen Aug 28, 2026 · Last updated Aug 28, 2026
Summary
This observational study measures three proteins, PTHrP, RANKL, and OPG, in the fluid that seeps from the gums. Researchers will compare levels in 81 adults split into three groups: healthy gums, gingivitis, and periodontitis. During a routine dental exam, they collect fluid samples with small paper strips and analyze the proteins in the lab. The goal is to see whether these proteins track with gum health and disease severity.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Routine periodontal examination and gingival crevicular fluid collection
- What this could lead to
- If the markers differ between healthy gums, gingivitis, and periodontitis, they could become tools for diagnosing or monitoring gum disease.
- What could go wrong
- This is a small observational study, so it can only show associations, not cause and effect. The markers may not prove useful in practice.

Who is studied
The study population consists of adult individuals seeking dental care at the Department of Periodontology, Faculty of Dentistry, Bolu Abant Izzet Baysal University. The population includes a total of 81 participants representing three distinct periodontal conditions: individuals with a healthy periodontium, individuals diagnosed with gingivitis, and individuals diagnosed with Stage III periodontitis.

Inclusion Criteria: * Individuals aged 18 years and older. * Presence of at least 20 natural teeth, excluding third molars. * For the Periodontally Healthy GrouP: PD ≤ 3 mm, BOP \< 10%, and no interproximal CAL or RBL. * For the Gingivitis Group: PD ≤ 3 mm, BOP ≥ 30%, and no interproximal CAL or RBL. * For the Periodontitis Group: Diagnosed with Stage III periodontitis (interproximal CAL ≥ 5 mm, PD ≥ 6 mm, and RBL extending to the middle third of the root or more apically). Exclusion Criteria: * Presence of systemic diseases that may affect periodontal tissues (e.g., cardiovascular diseases, atherosclerosis, immune system diseases, rheumatoid arthritis, obesity, cancer, and diabetes). * Use of antibiotics within the last 3 months. * Use of any medication that may affect periodontal tissues. * Presence of infectious diseases such as HIV, HBV, or tuberculosis. * Pregnancy or lactation. * History of periodontal treatment within the last 6 months. * Smoking
