Research on biological samples related to periodontitis and inflammation

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

Observational Assistance Publique - Hôpitaux de Paris · NCT06012019

This study is collecting samples from patients with gum disease and healthy individuals to see what causes periodontitis and how to spot it early.

What this trial studies

This observational study aims to collect biological samples from patients with gingivitis, periodontitis, and healthy controls to better understand the mechanisms that lead to periodontitis. Patients will be recruited from the oral medicine department at Charles Foix Hospital, where tissue, crevicular, salivary, and serum samples will be collected during routine surgical care. The study will analyze neutrophil subtypes and their functions, as well as the presence of specific bacteria associated with oral dysbiosis. The goal is to identify key factors that could help in early detection of patients at risk for periodontitis.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years old with varying degrees of periodontal health, specifically those with gingivitis, periodontitis, or healthy periodontium.

Not a fit: Patients with recent antibiotic or anti-inflammatory treatment, or those with specific neutrophil dysfunctions, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved early identification and management of patients at risk for periodontitis.

How similar studies have performed: While studies on periodontitis and neutrophil function exist, this specific approach focusing on biological sampling and the transition from gingivitis to periodontitis is relatively novel.
