The participants will be randomly assigned to one of two groups. The wound closure at the palatal donor area will be achieved with polytetrafluoroethylene (PTFE) sutures in one group and with high viscosity cyanoacrylate tissue adhesives on the other group. The surgical procedure will be performed by one of three calibrated periodontics residents (CS, JB, DR). Patients will be followed for 1 month post-operatively by the same resident to monitor the healing process and obtain patient feedback. Data will be collected at the baseline-day of the surgery, one day post-operatively and at the 1-week follow-up appointment. Randomization will be achieved using a computerized randomization scheme and will be communicated to the surgeon during the surgery by an independent examiner (AC). Participants will be block-randomized for each of the three operators for balance.
