The objective of this study was to compare acellular dermal matrix graft (ADM) combination with coronally advanced flap (CAF) on complete defect coverage, aesthetics and patient satisfaction with CAF alone for multiple recessions with gingival thickness (GT) <0.8 mm.

Forty‐eight Miller Class I multiple recessions ≥3 mm were divided into test (CAF + ADM) and control (CAF) groups. At baseline and 12 months, recession height (RH), keratinized tissue height (KT), GT, mean and complete defect coverage were evaluated. Patient satisfaction, root coverage aesthetic score (RES) and the correlation between GT and defect coverage were also assessed.

Baseline RH in CAF + ADM and CAF groups was 3.25 ± 0.34 mm and 3.21 ± 0.26 mm, respectively. Mean and complete defect coverage were 94.84% and 83.33% in test group, 74.99% and 50.00% in control group, respectively …
