What does gangrene refer to?

1. Inflammation of the gums

2. Death of tissue caused by lack of blood supply

3. Formation of cavities in teeth

4. Infection of the oral tissues

The correct answer is: Death of tissue caused by lack of blood supply

Gangrene refers specifically to the death of tissue that occurs due to a lack of blood supply, usually as a result of infection, injury, or underlying health conditions that impair circulation. This condition can result in severe pain, the affected area changing color, and potentially spreading if not treated promptly. The underlying mechanism involves the body’s tissues being deprived of oxygen and nutrients, leading to cell death. Understanding gangrene is essential in medical and dental fields because it can have significant implications. In dentistry, poor blood supply to the oral tissues can lead to complications, particularly in procedures like extractions or in patients with conditions such as diabetes or vascular disease, which affect blood flow. Recognizing the signs and symptoms of gangrene can enable practitioners to intervene early to prevent further complications.
