CRITICAL THINKING QUESTIONS
1. A patient who is scheduled for an x-ray expresses concerns about being exposed to radiation
because he witnessed the effects of radiation on his father, who died of cancer. How should the
dental radiographer respond to this patient’s concerns?
Discussion Guidelines: Dental x-rays use much less radiation than do medical x-rays, and substantially
less than is used in radiation therapy. Typically, a person will receive much more radiation from a day
2. Nathan Sawyer, a patient in your office, calls and states that he is moving out of state and
needs his dental radiographs before he moves next week. What precautions does the dental
radiographer need to take prior to giving Nathan his radiographs?
Discussion Guidelines: Radiographs are the property of the dentist, even though the patient or the
patient’s insurance company paid for them, because the dental radiographs are a part of the patient’s
