Dental Radiography Post-Radiotherapy

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