Is this trial a fit for you?

Likely a good fit

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

Probably not a fit

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

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.

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 gone: 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.
