Postoperative pain will be determined by the subjects recording their postoperative pain threshold using a Visual Analog Scale with scores from 1 to 10, with 1 indicating minimal pain and 10 indicating severe pain. If no pain is present, a score of 0 will be given. The levels of postoperative pain will be classified as none to minimum if the score is "0 to 3," moderate for "4 to 6," and severe for "7 to 10." None to minimal pain will mean little or no discomfort; moderate is any pain that bothers the subject and mildly affects normal function; and severe will be considered any pain that will not be tolerated and may even disrupt the subject's daily functions.

The laser Doppler flowmetry (LDF) technique to measure the blood perfusion of the free gingival graft (FGG) donor site. The value reported is blood flow at the FGG donor site (operated site) minus blood flow at the contralateral side of the palate (non-operated site). Perfusion Units (PU) are reported, which is blood flow through a given volume or mass of tissue with the unit of measure mL/100g/min.

One patient was not able to have Day 3 laser Doppler flowmetry (LDF) readings because of a death in the family, and this patient had to travel out of town for several days.

The non-invasive peroxide test is based on the principle that if the epithelium is discontinuous, the H2O2 diffuses into the connective tissue; the enzyme catalase acts on H2O2 to release water and oxygen: this is clinically shown by the production of bubbles on the wound. 3% H2O2 will be applied to the FGG donor site with a syringe and the appearance of bubbles will be recorded as a dichotomous variable (yes/no).
