Wound healing scoring system. Hematoxylin and Eosin, and Masson's trichrome staining were used to score wound healing based on epithelialization, fibroblast proliferation, new collagen fiber formation, new vessels, and inflammatory cell infiltration.

Epithelization	Fibroblasts	Collagen	New vessels	Inflammatory cells
Thickness of cut edges = 0	Absent = 0	Absent-granulation tissue = 0	Marked = 0	Marked (over 75 %) = 0
Migration of cells (<50 %) = 1	Mild-surrounding tissue = 1	Minimal-granulationtissue = 1	Moderate = 1	Moderate (50–75 %) = 1
Migration of cells (≥50 %) = 2	Mild-granulation tissue = 2	Mild-granulation tissue = 2	Mild to moderate tissue = 2	Mild to moderate (25–50 %) = 2
Bridging the excision = 3	Moderate-granulation tissue = 3	Moderate-granulation tissue = 3	Mild = 3	Mild (Less than 25 %) = 3
Keratinization = 4	Marked-granulation tissue = 4	Marked-granulation tissue = 4	Absent = 4	Absent = 4
