The present study aimed to analyze the early soft tissue healing characteristics and Fractal Dimension (FD) of extraction sockets preserved by Leukocyte-platelet-rich fibrin (L-PRF) and titanium prepared platelet-rich fibrin (T-PRF).
Materials and methods
57 single-tooth extraction sockets were included in the study, three groups were prepared: post-extraction sockets filled with L-PRF (n=19) and T-PRF (n=19), and control group; naturally healing sockets (n=19). Three months after tooth extraction, FD measurement was made in the center of the healing socket. The Landry Wound Healing Index (LWHI) and H2O2 bubbling test results for the complete wound epithelization (CWE) rates were recorded 1 and 2 weeks postoperatively. All patients were asked to record a visual analog scale (VAS) value for pain and the number of analgesics taken during the 3 days after the extraction.
CWE using H2O2 test result showed a significantly lower rate in the controls than in L-PRF and T-PRF groups at 1st week. At 2nd weeks, both of the test groups showed 100% CWE compared with only 40.7% in the control group. The VAS pain score was significantly higher in the control group than in L-PRF and T-PRF groups on the 1st day. However, no significant difference was found among the groups on 2nd day. FD value of control group was significantly lower than the L-PRF group and T-PRF group.
T-PRF and L-PRF similarly enhanced wound epithelization and reduced postoperative discomfort at extraction sockets. The T-PRF procedure resulted in higher FD compared to the L-PRF and control group.Le texte complet de cet article est disponible en PDF.
