BACKGROUND: Tissue regeneration within the periodontally involved furcation area is one of the most challenging aspects of periodontal surgery. The aim of this study was to evaluate the additional benefit of leukocyte and platelet-rich fibrin (L-PRF) to autogenous bone grafts (ABGs) in the treatment of mandibular molar degree II furcation involvement, comparing the clinical outcomes with those from open flap debridement (OFD)+ABG and OFD alone treatments.
METHODS: Fifty-four patients, exhibiting one buccal or lingual mandibular molar furcation defect, were randomly assigned to three treatment groups: OFD+ABG+L-PRF (n = 18); OFD+ABG (n = 18); and OFD (n = 18). Clinical (probing depth [PD], horizontal clinical attachment level [HCAL], vertical clinical attachment level [VCAL], gingival recession [GR]) and radiographic (vertical bone level [VBL]) parameters were evaluated at baseline and 6 months after treatment. HCAL change was the primary outcome.
RESULTS: No significant differences within each group were reported for GR changes, but statistically significant improvements in HCAL, VCAL, PD, and VBL were observed in all groups, except for VBL in the OFD group. At 6 months, the mean HCAL gain was 2.29 ± 0.18 mm in the OFD+ABG+L-PRF group, which was significantly greater than that in the OFD+ABG (1.61 ± 0.18 mm) and OFD (0.86 ± 0.18 mm) groups. Both OFD+ABG+L-PRF and OFD+ABG therapies produced a significantly greater clinical and radiographic improvement than OFD.
CONCLUSION: The addition of L-PRF to ABG produces a significantly greater HCAL gain and PD reduction as compared with OFD+ABG treatment in mandibular degree II furcation involvements.
