What condition refers to inflammation of the oral mucosa?

The condition that refers to inflammation of the oral mucosa is stomatitis. Stomatitis encompasses inflammation that can affect various parts of the mouth, including the cheeks, gums, tongue, lips, and roof or floor of the mouth. This condition can arise from a variety of causes, such as infections, irritants, or systemic diseases, and can present with symptoms like pain, swelling, ulcers, and difficulty in eating or speaking.

Glossitis specifically refers to inflammation of the tongue, making it a more localized condition compared to stomatitis. Cheilitis is inflammation of the lips, which is again more specific in location. Pharyngitis involves inflammation of the pharynx and is focused on the throat area, separate from the oral mucosa. Thus, stomatitis is the correct term for the broader context of oral mucosal inflammation.
