Inclusion Criteria: * All individuals received oral hygiene instructions and full-mouth scaling was performed. -They were instructed to perform a non-traumatic brushing technique (Roll) using an ultra-soft toothbrush * Individuals were re-evaluated at 8 weeks after initial therapy, and only full mounth plaque score and full mounth bleeding score \<15% were enrolled to the surgical procedure * mucogingival defects which for soft tissue graft application were indicated * For Less than 2 mm group, between 2.5 and 3.4 mm palatal thickness at each measurement points before graft harvesting * For 2 mm or more group, between 3.5 and 4.4 mm palatal thickness at each measurement points before graft harvesting. Exclusion Criteria: * periapical or palatal pathologies, * absence teeth from canine to first molar, * excessive forces including mechanical forces from orthodontics and occlusion, * systemic diseases that would contraindicate for periodontal surgery or interfere with tissue healing, chronic high-dose steroid therapy, radiation or immunosuppressive therapy, pregnancy, lactation, smoking, or allergy or sensitivity to any drug * Study participants had no history of drug therapy known to interfere with healing and to cause gingival enlargement * Individuals who had complication such as bleeding, necrosis and delay healing during or after surgery were excluded from the study.
