Mucositis
Pronunciation: myoo-koh-SY-tis
Inflammation and ulceration of the oral mucous membranes, most frequently occurring as a complication of cancer chemotherapy or head-and-neck radiation therapy.
Full Definition
Oral mucositis is a clinically significant and often dose-limiting complication of cytotoxic cancer treatments. It manifests as erythema, oedema, and painful ulceration of the oral mucosa, impairing eating, swallowing, speech, and oral hygiene. Dental hygienists play a key role in pre-treatment oral care optimization and in managing mucositis symptoms throughout and after therapy. Editors should note that 'mucositis' specifically implicates the mucosa (epithelial lining), distinguishing it from 'stomatitis,' which is a broader term for oral inflammation. In oncology dental literature, mucositis severity is often graded using the WHO or NCI CTCAE scale, references that may appear in documents undergoing editorial review.
Usage
Usage note: Distinguish from 'stomatitis' (general oral inflammation) and 'aphthous stomatitis' (recurrent ulcers of likely immune aetiology). In oncology contexts, always qualify with the causative therapy when possible.
