Overview

This study will include 50 patients diagnosed with healthy, reversible and irreversible pulpitis. IL-8, FGF-1 and VEGF levels will be compared using pulpal tissue, gingival crevicular fluid, dentinal fluid samples collected from the teeth of these patients. First, the DOS sample will be collected non-invasively using periopaper strips without local anesthesia. Then, the caries will be cleaned by applying local anesthesia and rubber dam to the patient and a dentinal fluid sample will be collected noninvasively using PVDF membranes. In teeth with pulp exposure due to caries, the pulp tissue that needs to be removed will not be disposed of but collected as a sample. Routine root canal treatment procedures will then continue and treatment of the teeth will be completed. The collected samples will be analyzed for IL-8, FGF-1 and VEGF levels by ELISA test.
