Evaluation of platelet-rich fibrin in the treatment of decorticated intrabony defects: a randomized clinical trial.

Objective: The objective of the present study was to evaluate the clinical and radiographic outcomes of intrabony defects treated with decortication (intramarrow penetration) alone versus decortication combined with platelet-rich fibrin in periodontitis patients followed up for 6 months postsurgery.

Method And Materials: A total of 46 intrabony defects from periodontitis patients with a mean age of 36.30 ± 6.
