Which condition is characterized by submandibular and lingual gland infection?

Ludwig's angina is a serious and potentially life-threatening infection that occurs in the submandibular and sublingual spaces, typically arising from the spread of infection from the teeth, particularly the second or third molars. This condition is characterized by bilateral swelling of the submandibular area, causing the floor of the mouth to become elevated and potentially obstructing the airway. The infection can involve the submandibular gland and the salivary glands in the area, leading to systemic signs of infection, such as fever and malaise.

The rapid progression of swelling can compromise the airway, making prompt recognition and management critical. Treatment often involves airway stabilization, along with antibiotic therapy and potentially surgical intervention to drain any abscesses.

In contrast, the other conditions listed do not typically present with the same pattern of infection in the submandibular and lingual glands. Angioedema is characterized by swelling due to vascular permeability changes, often in response to allergic reactions, rather than an infectious process. Thyroiditis refers to inflammation of the thyroid gland and is not associated with submandibular or lingual gland infections. Salivary stone blockage can cause localized swelling and pain in the salivary glands, but it
