Connective Tissue Graft vs Platelet-rich Fibrin in the Treatment of Gingival Recessions: A Randomized Split-mouth Case Series.

AIM AND

OBJECTIVE

Coronally advanced flap (CAF) with connective tissue graft (CTG) has been considered the gold standard for obtaining complete root coverage. However, some limitations have been reported with the use of CTG, especially because it increases morbidity and leads to postoperative pain and bleeding. Recently, platelet-rich fibrin (PRF) has been used in periodontal plastic surgery for the treatment of gingival recessions (GRs). The aim of this study was to evaluate the outcome of PRF combined with a CAF (test) compared to de-epithelialized connective tissue graft (DeCTG) + CAF (control) for GR coverage.

MATERIALS AND

METHODS

Ten healthy patients exhibiting mandibular or maxillary Miller class I and II were treated with PRF + CAF or DeCTG + CAF. GR, probing depth (PD), and gingival thickness (GT) were evaluated at baseline, 6 weeks, and 28 weeks postoperatively.

RESULTS

GR, PD, and GT differences between the test and control groups at 28 weeks were not statistically significant. GR was 3.30 ± 1.25 mm and 3.00 ± 1.63 mm (control vs test) group (baseline) and -0.10 ± 0.32 vs -0.20 ± 0.42 mm (7 months), respectively.

CONCLUSION

Within the limitations of the present study, it can be concluded that localized gingival recessions could be successfully treated with CAF + PRF or CAF + DeCTG.

CLINICAL SIGNIFICANCE: This study suggests that PRF membrane may be an alternative and valid graft material for treating localized gingival recessions Miller class I and II.
