In this study, it was aimed to evaluate the contribution of injectable platelet rich fibrin (i-PRF) to the healing of burn wounds using histopathological and thermographic data. For this purpose, 36 New Zealand rabbits were divided into two groups as the study and the control. After the burns were formed in rabbits in the study group, i-PRF was administered on 1 st , 3 rd and 7 th days. In the control group, 0.9% isotonic solution was administered on the same day. After burning, the temperature of burn area was measured with infrared thermal camera on 1 st , 2 nd , 3 rd , 7 th , 14 th and 21 st days. Randomly 6 rabbits were selected from both the study group and the control group. These rabbits were sacrificed on days 7, 14 and 21 and specimens were taken for histopathological examination from the burn area. In the examinations, it was observed that i-PRF increased cellular activity and accordingly, statistically significant temperature differences occurred between the burned area and normal skin on the 7 th , 14 th and 21 st days in the study group compared to the control group (p <0,05). The results of this research showed that i-PRF accelerates epithelization and collegenization in burn wounds. It is thought that many studies are needed in order to better understand the effect of i-PRF on wound healing.
