Top Line: How does dental hygiene influence the risk of radiation induced oral cavity mucositis?
The Study: This two-part study used explainable artificial intelligence to identify clinical and dosimetric parameters associated with oral mucositis during nasopharyngeal cancer radiation followed by a prospective intervention to target factors significantly associated with mucositis. Part 1 of the study used data from 430 patients with locally advanced NPC treated with definitive chemoradiation. Grade 3+ mucositis occurred in 39.1%. One of the factors with the strongest association with oral mucositis was the dental calculus index, which is a measure of hardened dental plaque build up. Phase 2 involved an intervention targeting dental calculus with professional cleaning prior to treatment in 148 patients. In this intervention group, the rate of severe oral mucositis was 8.1%–lower than that seen in the retrospective cohort.
TBL: This study identified dental calculus as an independent risk factor for severe oral mucositis during radiation for nasopharyngeal carcinoma. It also found that dental intervention to reduce dental calculus may reduce the rate of mucositis. | Zeng, Radiother Oncol 2025
