The Effect of Platelet-Rich Fibrin and Titanium Prepared Platelet-Rich Fibrin on Early Soft Tissue Healing of Extraction Sites

Splith mouth randomized control trial comparison of T‐PRF and subepithelial connective tissue graft in the treatment of maxillar multiple gingival recessions

AIM

The aim of this study is to compare the treatment efficacy of the bilateral multiple gingival recession areas with a titanium-platelet-rich-fibrin (T-PRF) and subepithelial connective tissue graft (SCTG) combined with a modified coronal advanced flap (MCAF) and the clinical results.

METHOD

In the study, 118 maxillary bilateral multiple Miller I recessions were treated. Gingival index, plaque index, probing pocket depth, gingival thickness, recession height, recession width, keratinized gingival width and open root surface area were measured at baseline and at 6 months. Postoperative pain levels Visual Analog Scale, healing status, wound healing index evaluated with. The results of both groups pre and postoperative were compared.

RESULTS

The initial recession height was 2.15 ± 1.0 mm in the T-PRF group; 2.04 ± 0.80 mm in the SCTG group. After 6 months, the mean root closure rate was 61.77%, 75.31% in T-PRF and SCTG group, respectively. Clinical attachment gain was achieved in both groups compared to baseline. When the results were compared, the gains achieved in the SCTG group were statistically significantly higher. İt was determined that patient satisfaction was higher in T-PRF group and wound healing was faster.

CONCLUSION

Considering the advantages of T-PRF such as providing effective results in the treatment of defects, patient satisfaction and rapid recovery; It can be applied as an alternative to SCTG.

CLINICAL SIGNIFICANCE

T-PRF can be an alternative to SCTG in the treatment of gingival recessions.

The Effectiveness of Advanced Platelet-Rich Fibrin in comparison with Leukocyte-Platelet-Rich Fibrin on Outcome after Dentoalveolar Surgery

METHODS

The study included 60 patients according to sample size calculation, recruited from patients seeking tooth extraction at oral and maxillofacial surgery clinic at Umm Al-Qura University, Faculty of Dentistry. Patients were divided into three groups. Group Ӏ included 20 patients managed by advanced platelet-rich fibrin after extraction. Group ӀӀ included 20 patients managed by leukocyte-platelet-rich fibrin after tooth extraction. Group ӀII included 20 patients left without any addition. Each group was further subdivided into surgical and nonsurgical extraction. Afterwards, patients in each group were assessed for postextraction pain by VAS, number of analgesics, and early soft tissue healing by LWHI.

RESULTS

The study outcomes demonstrate that the use of A-PRF significantly reduces postoperative pain in the 1st and 2nd day. VAS pain scores on the first day were significantly higher in the control surgical extraction group and L-PRF nonsurgical extraction group. In early soft tissue healing. The Landry Wound Healing Index (LWHI) was used after 1 and 2 weeks of extraction to evaluate the extraction site. In first week, the A-PRF group and L-PRF group (nonsurgical extraction) had a better healing index when compared to control group, and A-PRF group (surgical extraction) had a best healing index when compared to L-PRF and control groups. In the second week, individuals in the A-PRF group (surgical and nonsurgical extraction) had a better healing index when compared to L-PRF and control groups.
