CTG was harvested from 21 patients in each group. Donor site was treated with either GS (control) or GS+CY (test). Palatal tissue thickness, graft dimensions, working time (WT) and primary bleeding time were recorded intraoperatively. The data of pain perception (PP) will be measured using visual analog scale, quantity of analgesics (QA), secondary bleeding (SB), epithelization level (EL), and color match (CM) will be assessed prospectively. these outcomes will be evaluated in the first 7 days and 14th, 21th, and 28th days. Patient reported outcomes will be recorded using OHIB 14 questionnaire.

Donor site pain perception (PP)
Patients score their daily donor site pain perception (PP) level by giving numbers from 0 to 10 according to the visual analog scale (VAS) (0: no pain, 1: minimal pain, 10: severe pain)
Time frame: first week
Primary bleeding time (PBT)
Immediately after harvesting, sterile gauze was compressed to the palatal wound for 2 minutes, blood wiped once in every 30 seconds until bleeding stops. The duration was recorded as primary bleeding time (PBT).
Time frame: during surgery
Graft height (GH)
Dimensions were measured with periodontal probe
Time frame: during surgery
Graft width (GW)
Dimensions were measured with periodontal probe
Time frame: during surgery
Graft thickness (GT)
Dimensions were measured with periodontal probe
Time frame: during surgery
Working time (WT)
Harvesting process was recorded
Time frame: during surgery
Quantity of analgesics (QA)
Patients recorded the quantity of analgesics (QA) taken
Time frame: first week
Secondary bleeding (SB)
Patients recorded presence/absence of secondary bleeding (SB) (yes or no).
Time frame: first week

Sensation loss (SL)
Sensation loss (SL) was scored as none, medium or severe
Time frame: first week, second week , third week, fourth week.
Color match (CM)
Color match (CM) with the adjacent tissue was determined by using a VAS scale (0: absence of harmony, 10: excellent harmony)
Time frame: first week, second week, third week, fourth week.
Epithelization level (EL)
Epithelization level (EL) was scored as none, partial or full epithelization by means of bubble formation after dripping hydrogen peroxide (3%) to the wound surface following surgery
Time frame: first week, second week, third week, fourth week.
