Summary

The aim of this study was to evaluate the effect of injectable platelet rich fibrin (i-PRF) injection, in addition to routine root canal treatment, on alkaline phosphatase (ALP) and matrix metalloproteinase-9 (MMP-9) levels in teeth with chronic apical periodontitis. A total of 60 patients were included and randomly divided into two groups: the control group and the experimental group (i-PRF). Gingival crevicular fluid (GCF) samples and periapical exudate (PAE) samples were collected from the teeth at the first appointment, after completion of chemomechanical preparation. In both groups, calcium hydroxide was placed in the root canals, and the teeth were temporarily sealed with composite resin. While no additional procedure was performed in the control group, patients in the experimental group received submucosal i-PRF injection. The second samples were obtained after 4 weeks, and in the same session, the root canal treatment was completed, followed by permanent restoration. ALP and MMP-9 levels in the collected samples were analyzed using the ELISA test.
