Materials and methods: Sixteen patients with multiple recession defects (Cairo type I) were included in this randomized and controlled study. Forty-five gingival recession defects were randomly equally divided into three groups (n = 15): CAF + CGF (test site); CAF + A-PRF (test site), and CAF alone (control site). Clinical attachment level (CAL), vertical gingival recession (VGR), horizontal gingival recession (HGR), gingival thickness (GT), width of keratinized gingiva (KGW), percentages of the mean (MRC), and complete root coverage (CRC), patient esthetic score (PES), and hypersensitivity score (HS) were recorded at baseline and 6 months after surgery. Patient comfort score (PCS) was evaluated at the day of surgery. Results: Significant improvements were determined in CAL, VGR, HGR, KGW, and GT at 6 months when compared to baseline levels in intra-group comparisons for all groups, and also GT was increased in CAF + A-PRF and CAF + CGF compared to CAF alone at 6 months in intergroup comparisons (p < 0.05). At 6 months, MRC was detected 85.66 ± 22.68% in the CAF + CGF, 90.88 ± 20.87% in the CAF + A-PRF, and 75.10 ± 32,37% in the CAF alone, and a significant increase was detected in the CAF + A-PRF group compared to CAF alone (p < 0.05). CRC in CAF + CGF was 66.66%, in CAF + A-PRF 80% and in CAF alone was 53.33% (p > 0.05). PES and HS values showed significant improvement from baseline to 6 months for all groups and also in CAF + CGF and CAF + A-PRF compared to CAF alone at 6 months in intergroup comparisons (p < 0.05). Conclusions: The present study showed that the use of A-PRF and CGF membranes in GR therapy may have an additional benefit in GT increase and also A-PRF may increase the percentages of MRC. The use of A-PRF and CGF membranes may be beneficial in terms of improving patient-related parameters. Clinical relevance: A-PRF and CGF may be superior to CAF alone in terms of patient-related parameters and GT increase in multiple recession defects.
