Evaluation of advanced platelet-rich fibrin compared to subepithelial connective tissue graft in the surgical management of interdental papilla recession: a randomized controlled trial.

Objectives: The current study aims to compare advanced-platelet-rich fibrin membrane (A-PRF) to connective tissue graft (CTG) using Han and Takei's approach.

Materials And Methods: The defective papilla was randomly allocated to either the control group (CTG) or to the experimental group (A-PRF). Papilla height (PH) and percent change in the gingival black triangle (GBT) area were recorded at 1, 3, 6, 9, and 12 months.
