Age‐related local versus systemic early phase wound healing dynamics following free gingival graft harvest

Journal of Periodontology, EarlyView.
Abstract Background Free palatal gingival grafts (FGG) are commonly harvested during mucogingival procedures. The present study investigates age‐related local and systemic early secondary wound healing outcomes, following FGG harvest in a rat model. Methods A 4.2 mm diameter defect was created in the palate of 24 younger (2 m) and 24 older (6 m) Wistar
