Table 1. Thermal effects on tissue at varying temperatures (50,51).

Effect	Temperature (°C)	Histopathological Effects
Hyperthermia	40	Reversible cell injury, conformational changes of cells, shrinking of collagen, deactivation of enzymes
Devitalization	42	Same as above
Coagulation	60	Denaturation of proteins, hyalinization of collagen, membrane permeability changes
Desiccation	100	Tissue drying, extracellular vacuoles, rupture of vacuoles
Carbonization	200	Tissue ablation and carbonization
Vaporization	300–1,000	Vaporization of carbon
