Clinical and Biochemical Effects of Repeated Injectable Platelet-Rich Fibrin Application in Periodontitis Treatment: A Randomized Controlled Clinical Trial.

Researchers tested whether injecting platelet-rich fibrin into periodontal pockets alongside scaling and root planing improved outcomes compared to saline alone. The fibrin-treated sites showed better attachment and lower inflammatory markers at 3 months, though pocket depth improvements were not significantly different.
