Aim:
To evaluate the patient-reported pain perception after palatal graft harvesting during a 4 weeks healing period
Materials & Methods:
Ninety patients, scheduled for different periodontal and peri-implant plastic surgeries requiring palatal mucosal graft harvesting, were consecutively recruited. Mucosal thickness was measured at the donor sites with an ultrasonic device prior to the surgeries. Graft thickness, length, and width were assessed after harvesting, and the wound areas were calculated. Based on a Visual Analogue Scale (VAS), the patients were asked to report their perceived pain after the intervention and 1, 3, 7, 14, 21 and 28 days thereafter.
Results:
Pain was most pronounced on the first postoperative day and decreased within the course of time. Graft thickness directly correlated with the amount of pain perceived while increased palatal mucosal thickness before and after graft harvesting decreased pain levels. The denuded wound surface area, however, did not influence the perceived pain level.
Conclusions:
The wound depth at the donor site (graft thickness) was positively correlated with the patient's perception for pain. The wound surface area, however, did not influence the perceived pain level.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
