| The results of this study showed a statistically significant difference in bone pocket repair when the L-PRF (Leukocyte Platelet Rich Fibrin) membrane was used in relation to the blood clot. There was a significant difference regarding the decrease in bone store volume after 90 days, both for the L-PRF(Leukocyte Platelet Rich Fibrin) membrane and for the blood clot. The group that used L-PRF (Leukocyte Platelet Rich Fibrin) was more effective in terms of bone repair, decreasing the size of the bone store in volume, than the group that used the blood clot, after 90 days, the decrease was 48.48% for the L-PRF(Leukocyte Platelet Rich Fibrin) and 29.26% for blood clot, and this percentage was also statistically significant. | — |
