Understanding the links between periodontitis, inflammation, and diabetes

Official title: Characterization of the Immuno-inflammatory Response Involved in Bone Destruction During Periodontitis: Study With Biological Collection

Run by Assistance Publique - Hôpitaux de Paris · NCT04831060 · Data updated 2026-11-12

This study is trying to understand how periodontitis and inflammation are connected to diabetes by looking at biological samples from patients with severe gum disease and healthy people.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults over 18 with stage 3 or 4 periodontitis or peri-implantitis, as well as healthy individuals requiring dental care.

Probably not a fit

Patients with no history of periodontitis or peri-implantitis and who do not require dental treatment may not benefit from this study.

What this trial studies

This observational study aims to investigate the pathogenic mechanisms involved in periodontitis and peri-implantitis by characterizing specific molecular markers that reflect the activity of these conditions. Biological samples such as plaque, saliva, and crevicular fluid will be collected from patients with advanced stages of periodontitis or peri-implantitis, as well as from healthy individuals. The study seeks to improve knowledge of the disease's pathogenesis, identify target molecules involved in tissue destruction, and determine molecular profiles of patients at risk. This research is non-interventional and will be conducted across multiple centers as part of routine care.

Why it matters

Potential benefit: If successful, this study could lead to improved prevention and treatment strategies for periodontitis and peri-implantitis.

How similar studies have gone: Other studies have shown success in identifying biomarkers for periodontal diseases, making this approach promising yet still requiring further exploration.

Inclusion Criteria:

Common criteria for all patient groups

* Patient \> 18 years old
* Patient affiliated to a social security system, beneficiary or beneficiary of a right other than AME

\- Case peri-implantitis: Patients with at least 1 implant affected by peri-implantitis. Diagnosis is based on the findings of the interview, clinical examination and radiographic examination.

Control group:

Patient with gingival health on intact or reduced periodontium with no history of periodontitis or peri-implantitis and requiring surgical care such as dental avulsion and pre-prosthetic periodontal corrective/aesthetic surgeries (coronal elongation, neck alignment.)

Exclusion Criteria:

* Patients who have received antibiotic prophylaxis, antibiotic therapy, or anti-inflammatory treatment within 3 months prior to inclusion
* Pregnant or breastfeeding women
* Patient included in another interventional research protocol or in a period of exclusion.
