Oral health-related quality of life in Tunisian patients following radiotherapy for head and neck tumors: a cross-sectional study

a significant proportion of patients experienced poor OHRQoL post-radiotherapy, influenced by factors such as age, radiation dose, radiotherapy technique, and dental visit frequency. IMRT was associated with better OHRQoL compared to conventional techniques. Limited compliance with oral health protocols underscores the need for enhanced pre- and post-radiotherapy dental care strategies, improved patient education, and increased accessibility to advanced radiotherapy techniques in Tunisia. Larger studies with extended follow-up are necessary to validate these findings and enhance post-radiotherapy oral healthcare policies.
