Multiple gingival recessions associated with non‐carious cervical lesions treated by partial restoration and modified coronally advanced flap with either connective tissue graft or xenogeneic acellular dermal matrix: A randomized clinical trial

Background This study aimed to compare a connective tissue graft (CTG) to a (porcine) xenogeneic acellular dermal matrix (XDM), both associated with modified coronally advanced flap (MCAF) and partial resin composite restoration to treat multiple combined defects (CDs). Methods Seventy‐eight defects in 38 patients presenting multiple combined defects, that is, gingival recession associated with non‐carious cervical lesions, were treated by partial resin composite restoration (apical margin up to 1 mm of the estimated cement‐enamel junction) and MCAF along with CTG or XDM. After 6 months, the groups were compared with regard to clinical, patient‐centered, and esthetic outcomes. Results CD coverage was 72.9% for CTG versus 50.7% for XDM (P
