The type of necrosis is usually coagulative due to ischemia (e.g. in gangrene of the bowel, gangrene of limb).\xa0 On the other hand,\xa0 gangrenous or necrotizing inflammation is characterized by primary inflammation provoked by virulent bacteria resulting in massive tissue necrosis. Thus, the end-result of necrotizing inflammation and gangrene is the same but the way the two are produced is different.\xa0 The examples of necrotising inflammation are gangrenous appendicitis, gangrenous stomatitis (noma, cancrum oris). There are 2 main forms of gangrene—dry and wet, and a variant form of wet gangrene called gas gangrene. In all types of gangrene, necrosis undergoes liquefaction by the action of putrefactive bacteria.\nHarsh Mohan\xa0 Pathology for dental students 7th ed page 43', 'role': 'assistant'}]
