Histological scoring of wound regeneration.

Score	Epithelial covering			Dermal differentiation
	Presence	Degree (mono- or multilayer designed)	Conical structure
0	Absence of epithelialization	Monolayer	Not present
1	Partial reepithelialization	Partial multilayer	Partially present	Thin, dense, and monotonous fibrosis
2	Complete reepithelialization	Multilayer	Present	Thicker but still dense and monotonous fibrosis
3				Two layers but not completely discreet
4				Two discreet layers with superficial fibrosis and loose alveolar tissue in the deep layer
