Recently, the use of type I collagen obtained from Nile Tilapia (Oreochromis niloticus) was proposed for the treatment of second and third-degree burning lesions and diabetic ulcers due to its occlusive and healing properties. The aim of this report is to describe the use of Nile tilapia skin as an occlusive barrier to protect palatal wounds after the removal of free autogenous soft tissue grafts. Two patients with a deficiency in the height of keratinized mucosa were indicated for treatment with free gingival grafts. The palatal donor area was covered with a Nile tilapia skin, stabilized by sutures. Seven days after surgery, patients returned for post-operative care. Patients’ reported outcomes were investigated by the use of a visual analogue scale and included pain, discomfort, impact on chewing and speaking. Analgesics consumption was also recorded. Standardized photographs were obtained to monitor wound healing. Patients were followed up for 30 days. Patients reported reduced pain levels, with low consumption of analgesics during the first week after surgery. No discomfort or difficulty in chewing or speaking was reported. No complications such as hemorrhage or edema were observed. These findings suggest that the Nile Tilapia skin may be an interesting alternative as an occlusive biological dressing in palatal wounds harvest of free gingival grafts.
