What does the term "angioedema" refer to?

The term "angioedema" specifically refers to swelling that occurs beneath the skin, particularly in tissues such as the face, lips, throat, and sometimes the digestive system. This swelling is often related to an allergic reaction or a hypersensitivity response and is characterized by rapid development. It differs from other skin reactions like rashes or dryness, which involve different underlying mechanisms and symptoms. Understanding angioedema is crucial in dental practice, as it can have implications for patient management, especially in relation to allergies to anesthetics or medications used in dental treatment. Recognizing the signs of angioedema and its potential severity can help in effective and timely interventions.
