Patients who have had radiation therapy for cancer of tissues located in the head or neck region should avoid dental radiographs

Indicate whether the statement is true or false

False. The dose of radiation required for dental x-rays is extremely small compared to that used for radiation therapy. The effects of very high doses involved in therapeutic radiation may increase susceptibility to diseases, such as tooth decay. This can occur as a result of a decrease in secretions of the salivary glands. It is especially important that patients who have had radiation therapy for cancer of tissues in the head or neck regions have dental x-ray exams as needed, to detect problems at an early stage.
