Table 1: Criteria to evaluate histological scores of wound healing.


1–3None to minimal cell accumulation, no granulation tissue or epithelial travel
4–6 Thin immature granulation, that is, dominated by inflammatory cells but has few fibroblasts, capillaries, or collagen deposition, minimal epithelial migration
7–9Moderately thick granulation tissue can range from being dominated by inflammatory cells to more fibroblasts and collagen deposition, extensive neovascularization, epithelium can range from minimal to moderate migration
10–12Thick, vascular granulation tissue dominated by fibroblasts and extensive collagen deposition, epithelium partially to completely covering the wound
