Cancrum Oris, also known as necrotizing ulcerative gingivitis or noma, is a severe and often painful condition that primarily affects the mouth and face. It typically begins as a gum infection, leading to the rapid destruction of oral tissues, including the gums, cheeks, and lips. This condition is most common in malnourished children and can result from poor oral hygiene, weakened immune systems, or underlying health issues. The disease can progress quickly, causing significant disfigurement and complications if left untreated. Treatment usually involves antibiotics, proper oral care, and nutritional support. Early intervention is crucial to prevent severe outcomes and improve recovery chances.
