Comparison of the effect of A-PRF and L-PRF application to palatal donor sites on quality of life and wound healing after free gingival graft surgery

Objectives: This study compared the effects of leukocyte platelet-rich fibrin (L-PRF) and advanced platelet-rich fibrin (A-PRF) on patients' quality of life and the healing of palatal wounds after free gingival graft harvesting. Method and materials: After free gingival graft harvesting, palatal donor sites of 36 patients were assigned to one ofthree groups: L-PRF group, A-PRF group, or palatal stent + periodontal pack group (control group). Wound healing was evaluated by H2O2 test. Pain was evaluated byvisual analog scale and number of analgesics consumed. For patient quality of life, the Oral Health Impact Profile-14 (OH l P-14) questionnaire was utilized. Results: Complete epithelialization was higher in the control group on day 7 than in the test groups (P<.05). Complete epithelialization was achieved in all groups 14days postoperatively. Visual analog scale scores for pain and the number of analgesic tablets consumed were similar in all groups (P> .05). OHIP-14 total scores were similar in all study groups at 7days postoperatively (P>.05). OHIP-14 total and physical pain score was lower in the L-PRF group than the A-PRF group at 14days postoperatively (P<.05). Conclusion: Aside from the slight superiority of L-PRF overA-PRF, it can be concluded that both PRF proceduren have similar effects on palatal wound healing and quality of life.
