Comparative evaluation of the efficacy of xenogeneic collagen matrix and platelet-rich fibrin in the treatment of gingival recession.

Aim: The main focus of the study is to determine the difference between the efficacy of xenogeneic collagen matrix (XCM) versus platelet-rich fibrin (PRF) adjunct to coronally advanced flap to treat the gingival recession.

Background: Because of esthetic concerns or root hypersensitivity, typical necessity dictates for buccal gingival recession treatment. This study was planned to evaluate and compare the efficacy of XCM with PRF in the treatment of the recessed gingiva.
