“…Other risk factors include developmental defects such as bone dehiscence, chronic trauma, frictional injury due to scratching of gingiva (tooth brushing), tooth malposition of teeth, gingival ablation, abnormal frenum attachment, aging, smoking, and iatrogenic dentistry injury [8]. There are several periodontal surgical methods that have been developed to close the exposed root surface that arises from gingival recession, such as free gingival graft (FGG) [9], coronary positioned flap, semilunar coronally positioned flap [10], subepithelial connective tissue graft (CTG) [11], pediculated soft tissue grafts [12], thrombocyte-rich Fibrin (TRF) [13], and acellular dermal matrix [14]. These operations aim to increase the amount of attached gingiva and stop gingival recession, subsequently decreasing the sensitivity of the root and improving plaque control and aesthetic appearance [15].…”
