Platelet-rich fibrin (PRF) has emerged as one of the promising regenerative materials in the field of periodontics. Hence, this study evaluated the efficacy of subepithelial connective tissue graft (SCTG) and PRF in surgical reconstruction of interdental papillae using Han and Takei technique. A total of 20 sites with Class I and Class II interdental papilla defects were assigned to two groups (Group 1 - Han and Takie technique + SCTG and Group 2 - Han and Takie technique + PRF). Parameters such as papillary height (PH), distance from t
