What is the main purpose of using a lead apron during dental x-rays?
Correct!
Wrong!
A lead apron protects vital organs from unnecessary radiation exposure, particularly the reproductive organs and thyroid.
Which tissue is most sensitive to radiation exposure?
Correct!
Wrong!
Reproductive and rapidly dividing cells, like those in bone marrow, are the most sensitive to ionizing radiation.
How should dental x-ray films be stored to maintain quality?
Correct!
Wrong!
X-ray films should be kept in a cool, dry place away from radiation, heat, and light to prevent fogging or damage.
Which of the following helps reduce patient radiation exposure?
Correct!
Wrong!
Using a rectangular collimator restricts the x-ray beam to the size of the film, significantly reducing radiation exposure to the patient.
When is it safe for the dental assistant to remain in the room during an x-ray?
Correct!
Wrong!
The assistant should never remain in the operatory during x-ray exposure unless protected by a lead barrier or wall.
What is the ideal distance for the operator to stand from the x-ray tube head during exposure?
Correct!
Wrong!
To avoid scatter radiation, the operator should stand at least 6 feet away and at an angle of 90 to 135 degrees from the primary beam.
