For root coverage of single maxillary recession defects, CAF + CTG was more effective than TUN + CTG (ClinicalTrial.org-NCT02814279).

CTG and CTG + PR were effective to treat CD. Use of PR resulted in better gingival margin contour and DH reduction, without effect on CD coverage by CTG. (NCT02817763).

CTG or CTG+RC can successfully treat gingival recession associated with B+ non-carious cervical lesion, but less sensitivity may be expected with the combined approach (NCT02423473).
