ABSTRACT
BACKGROUND:Previous studies have found that platelet-rich fibrin has a good ability to induce gingival soft tissue repair and regeneration. OBJECTIVE:To observe the effects of platelet-rich fibrinversus colagen membrane on gingival soft tissue healing, and to evaluate the ability of platelet-rich fibrin to repair gingival defects. METHODS:Twenty-two patients (2 premolar teeth and 20 molars) scheduled for premolar or molar removal or ridge preservation due to various reasons were selected and randomized into two groups. Bio-Oss was implanted into the extraction socket folowed by covering with platelet-rich fibrin or colagen membrane. Healing time and healing rate of gingival defects were detected to evaluate the ability of platelet-rich fibrin to promote gingival tissue healing at 1-2 weeks after Bio-Oss implantation. RESULTS AND CONCLUSION:The healing time was (12.17±2.25) days in the platelet-rich fibrin group and (17.30±2.58) days in the colagen group. The healing rate of the platelet-rich fibrin group was notably higher than that in the colagen membrane group at 1 and 2 weeks after Bio-Oss implantation. These findings indicate that platelet-rich fibrin is better than colagen membrane to improve the healing of gingival soft tissues with a shorter healing time.
