Mucositis
Pronunciation: myoo-koh-SY-tis
Inflammation of the mucous membrane lining the oral cavity, commonly occurring as a side effect of chemotherapy or radiotherapy.
Full Definition
Oral mucositis is a painful, ulcerative condition of the oral mucosa arising as a direct toxicity of cancer treatments, particularly high-dose chemotherapy and head-and-neck radiotherapy. It is graded on standardized scales such as the WHO Oral Toxicity Scale or the NCI Common Terminology Criteria. In dental editorial contexts, 'mucositis' must be distinguished from 'peri-implant mucositis', which specifically refers to reversible inflammatory changes around dental implants. Editors working in oncology dentistry or implant literature must apply the correct term precisely.
Usage
Usage note: In implant dentistry texts, 'peri-implant mucositis' is a distinct, defined entity; never abbreviate it to 'mucositis' alone without the qualifier, as confusion with chemotherapy-induced mucositis may result.
