Biological Effects of Radiation
Dental Radiography Post-Radiotherapy

A common question gets asked about the consequences of exposing a patient to dental x-ray after radiation therapy. The radiation doses from intraoral, panoramic radiographs, Cone beam, CT, or even medical CT are extremely low compared to the doses of radiotherapy. The only concern would be obtaining intraoral radiographs within 6 months of radiotherapy, i.e., before mucosal healing, and further traumatizing the mucosa in the process.⁶
