Effect of Melatonin on Palatal Wound Healing (Randomized Controlled Clinical Trial)

Effect of Topically Applied Melatonin (N-ACETYL-5-METHOXY TRYPTAMINE) Loaded Gelatin Sponge on Palatal Wound Healing (Randomized Controlled Clinical Trial)

The aim of the study is to assess the effect of topical melatonin loaded gelatin sponge on donor palatal site healing, after palatal graft harvesting.

Autogenous soft tissue grafts can be considered the gold standard treatment for many muco-gingival problems. The most common site for harvesting soft tissue grafts is the palate. Many harvesting techniques have emerged, but the epithelialized graft harvesting technique is one of the most reliable and effective techniques as it imparts the superficial section of the connective tissue which contains the highest amount of lamina propria. Unfortunately, it leaves an open palatal wound healed by secondary intention, increasing pain and post-operative morbidity. In order to overcome these inadequacies investigators will cover the donor site with melatonin loaded gelatin sponge and evaluate its effect on the healing process.

2. Patients who have at least 4 mm thickness of palatal mucosa (at donor site)

Exclusion Criteria:

1. History of smoking.
2. Patients who have any known disease that interfere with periodontal surgery.
3. Patients who have any dermal or autoimmune diseases.
4. Patients who have any previous adverse reactions to the products (or similar products) used in this study.
