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

Abstract

This study compared the effects of L-PRF and A-PRF on patients' quality of life and the healing of palatal wounds after free gingival graft harvesting. After FGG harvesting, palatal donor sites of 36 patients were assigned one of the three group: 1)L-PRF group, 2) A-PRF group and 3) Palatal stent+periodontal pack group (control group).Wound healing was evaluated by H2O2 test. Pain was evaluated by visual analog scale (VAS)and number of analgesics consumed. For patient quality of life, the Oral Health Impact Profile-14 (OHIP-14) questionnaire was utilized. Complete epithelialization was higher in thecontrol group on the 7th day than test groups (p< 0.05). Complete epithelization was achievedin all groups 14th day postoperatively. VAS scores for pain and the number of analgesic tabletsconsumed were similar in all groups (p >0.05). OHIP-14 total scores were similar in all studygroups at 7th day postoperatively (p>0.05). OHIP-14 total and physical pain scores was lowerin L-PRF group than A-PRF group at 14th day postoperatively (p< 0.05). Asidefrom the slight superiority of L-PRF over A-PRF, it can be concluded that both PRF procedureshave similar effects on palatal wound healing and quality of life.
