Radiation-Induced Caries: Exploring the Pathway to Manage the Challenge

Abstract

Radiation-induced caries represent a frequent and serious complication of head and neck radiotherapy, significantly affecting patients' quality of life. Their development results from several factors, including the direct effects of radiotherapy on dental tissues, as well as indirect effects related to xerostomia and changes in saliva. Diagnosis is based on clinical and radiographic assessment, which often reveals a specific pattern of demineralization. The management of these caries requires a comprehensive approach, combining prevention, treatment of lesions, and regular follow-up. It is essential to establish long-term fluoride prophylaxis, and advice on oral hygiene and nutrition, in order to prevent new lesions. The choice of dental restorations must be considered according to the state of salivation and the caries risk, favoring materials adapted to the specificities of radiotherapy.
