Osteoradionecrosis (ORN) is a serious complication of radiation therapy in cancer treatment where radiated bone becomes necrotic and exposed. [1] ORN occurs most commonly in the mouth during the treatment of head and neck cancer, and can arise over 5 years after radiation. [2]
The Wall Street Journal ran a story (in 1989 or after) titled "The Radium Water Worked Fine until His Jaw Came Off". [7] Stories such as that of the Radium Girls and Eben Byers's death went public and due to public pressure and outrage, the Food and Drug Administration banned most radiation-based patent medicines in 1932.

Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor.
If rampant caries is a result of previous radiation to the head and neck, it may be described as radiation-induced caries. Problems can also be caused by the self-destruction of roots and whole tooth resorption when new teeth erupt or later from unknown causes. Children at 6–12 months are at increased risk of developing dental caries. [99]
Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments (dental drills) to prepare the tooth and can be performed in settings with no access to dental equipment.
Although this type of image is an excellent indication of the basic quality of the treatment plan, the quality of film images can be poor. A BEV can be created using a radiation therapy simulator which mimics the treatment geometry (couch angle, gantry angle, etc.) using an X-ray source instead of the higher energy treatment source. The jaws ...
[2] [1] Radiation proctitis most commonly occurs after pelvic radiation treatment for cancers such as cervical cancer, prostate cancer, bladder cancer, and rectal cancer. RAVE and chronic radiation proctopathy involves the lower intestine , primarily the sigmoid colon and the rectum, and was previously called chronic radiation proctitis, pelvic ...
Conventional radiation techniques such as external beam radiotherapy (EBRT) following surgical removal of the tumor have several drawbacks: The tumor bed where the highest dose should be applied is frequently missed due to the complex localization of the wound cavity even when modern radiotherapy planning is used.
