Assessment of a Carvacrol-loaded Absorbable Gelatin Sponge Used As a Palatal Dressing Following Free Gingival Graft Harvesting: a Randomized Clinical Study

1-absorbable gelatine sponge soaked in carvacrol oil placed in the palatal donor site. Procedure: The palatal sites will be anaesthetized with 0.3 ml of a solution of 4% Articaine and 0.001% Adrenalin. Graft harvesting will be performed by basic surgical techniques previously described by Miller (1982). A rectangular shaped piece of mucosa will be harvested from the area of the hard palate by a split-thickness dissection. The graft will then be used as it on the recipient bed. The graft dimensions will be recorded (width and length). Denuded palatal area will then be protected using a carvacrol loaded absorbable gelatin sponge (test group)
