What this trial studies

This study investigates the interactions between biomarkers of type 2 diabetes mellitus (T2DM) and periodontal disease (PD) in a multi-center cross-sectional design. Participants aged 30 to 70 will be categorized into nine subgroups based on their hemoglobin A1c (HbA1c) levels and PD staging. The study aims to evaluate immune signatures, clinical biomarkers, and the influence of various biomarkers on the relationship between T2DM and PD. Each participant will be involved for up to 30 days, including a screening visit and a single visit for specimen collection.

Who should consider this trial

Good fit: Ideal candidates are adults aged 30 to 70 with or without type 2 diabetes and varying stages of periodontal disease.

Not a fit: Patients with bleeding disorders, active infections, or recent neoplastic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the relationship between periodontitis and type 2 diabetes, potentially leading to improved management strategies for these conditions.

How similar studies have performed: Other studies have explored the relationship between periodontal disease and diabetes, indicating potential for meaningful insights, though this specific approach may be novel.

Exclusion Criteria:
