Root coverage procedures using various autogenous pedicle and free gingival grafts have been commonly used in periodontics. Recently, a substitute for palatal donor tissue in gingival augmentation procedures has been introduced which is acellular dermal matrix allograft (ADMA). This study was undertaken to examine the potential of ADMA to be used as a substitute for autogenous connective tissue graft material in root coverage procedures in cases with Miller's class I recession defects. Within the limitations of the clinical observations, it is suggested that ADMA can be used as a substitute to free autogenous grafts but, further clinical and histological studies would be necessary to understand the healing process of the surgical wound.
