PERIOSTEUM
Ten patients participated in this trial. The mean age was 33.9 ± 11.1 years old and the male/female ratio was 6:4. None of the subjects dropped out during the 8‐week follow‐up. One side of each patient was randomly assigned to the test (MARF + PRF) or control (MARF) group, while the contralateral side was assigned to the other group. A flow diagram of the study participants is provided (Figure Flow diagram of the studyPPD at baseline and follow‐up were almost the same and there was no difference in either group.At baseline, the average width of the attached gingiva was 1.15 ± 0.52 for the test group and 0.8 ± 0.82 for the control group. The mean increase in the attached gingiva after 8 weeks was 1.7 mm in the MARF group and 2.3 mm in the PRF group, which was significantly higher in the PRF group compared with the MARF group (At baseline GT was 0.79 ± 0.16 and 0.74 ± 0.22 mm for the test and control groups, respectively. After 8 weeks, the GT was 1.09 ± 0.09 in the PRF group and 0.86 ± 0.16 mm in the MARF group. GT is increased by 0.11 mm in the MARF group and 0.29 mm in the PRF group, with a significant statistical difference between those values (The VD at baseline and follow‐up are recorded in Table Clinical measurements at baseline and 8‐week postop (mean ± SD) and clinical parameter change (Δ) from baseline to 8 weeks postop
Abbreviations: AG, attached gingiva; GT, gingival thickness; MARF, modified apically repositioned flap; PPD, probing pocket depth; PRF, platelet‐rich fibrin; VD, vestibular depth.Postoperative pain is assessed by using the VAS questionnaire a day after surgery. The VAS values associated with PRF and MARF groups were almost the same and were not different in either group (Wound shrinkage was measured by comparing the apicocoronal dimension of the exposed periosteum with the newly attached gingiva 8 weeks postop. The wound shrinkage was 51.1% in the control group and 30.9% in the test group, which was significantly higher in the MARF group (Table Comparison postoperative pain and shrinkageAbbreviations: MARF, modified apically repositioned flap; PRF, platelet‐rich fibrin.
