Abstract:
Objective: The aim of this study was to assess the clinical effects of concentrated growth factor (CGF) in combination with coronally advanced flap (CAF) compared with platelet rich fibrin (PRF)+CAF for the treatment of multiple adjacent gingival recessions (GRs). Method and materials: 18 subjects with total of 76 Type I GRs in the maxilla were included. Recessions were randomly treated according to a split-mouth design by means of CGF+CAF (39 defects, CGF side), or PRF+CAF (37 defects, PRF side). Clinical outcomes were evaluated at 6 months. Results: The mean root coverage was 86.32% and 80.86%, and complete root coverage was 61.53% (24/39) and 51.35% (19/37) for CGF side and PRF side, respectively, at 6 months. Statistically significant gains were observed in the terms of clinical attachment level, recession depth, keratinized gingiva width, gingival thickness, and recession width in the both sides at 6 months compared to baseline values; no statistically significant difference was observed in these parameters between the two sides at 6 months. Conclusions: According to results, the use of CGF+CAF was not superior to PRF+CAF in providing additional benefits in clinical parameters. Keratinized gingiva width and gingival thickness significantly increased with the use of CGF and PRF membranes together with CAF. (QuintessenceInt2022;53:288-297;doi:10.3290/j.qi.b2407765)
