Fatal necrotizing fasciitis of dental origin

Necrotizing fasciitis is a potentially fatal, acute bacterial infection characterized by extensive fascial and subcutaneous tissue necrosis. Four factors that contribute significantly to the morbidity and mortality of necrotizing fasciitis are: 1) delayed treatment, due to difficulty in recognizing the condition; 2) inappropriate treatment; 3) host debilitation; and 4) a polymicrobial infection.
