Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with healthy teeth, reversible pulpitis, or irreversible pulpitis as defined by specific clinical criteria.

Probably not a fit

Patients requiring antibiotic prophylaxis, those with diabetes or hematological diseases, or pregnant women may not benefit from this study.

What this trial studies

This observational study involves 50 patients diagnosed with healthy, reversible, and irreversible pulpitis. It aims to compare the levels of biomarkers IL-8, FGF-1, and VEGF in pulpal tissue, gingival crevicular fluid, and dentinal fluid samples collected from these patients. Non-invasive methods will be used to collect samples, followed by routine root canal treatment procedures. The collected samples will be analyzed using the ELISA test to determine the biomarker levels associated with different pulp conditions.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of pulpitis and improve diagnostic accuracy for dental treatments.

How similar studies have gone: While similar studies have explored biomarker levels in pulpitis, this specific comparison of IL-8, FGF-1, and VEGF is relatively novel.
