Answer: A bitewing is used to diagnose caries and early stage
bone loss from periodontal disease.
◉ What causes overlapped contacts in radiography?
Answer: Incorrect horizontal angulation.
◉ What does not affect x-ray production?
Answer: Resistance or Ohms.
◉ What is a safety measure for patient protection during x-rays?
Answer: Using a sensor or film holding device.
◉ What is true about collimation and filtration?
Answer: They restrict the size and shape of the x-ray beam and
reduce patient exposure.

Answer: The effects of radiation are cumulative.
◉ What is the most important concept for radiation safety?
Answer: As Low As Reasonably Achievable (A.L.A.R.A).
◉ What is a safety measure for operator protection during x-rays?
Answer: The operator should stand behind an appropriate barrier.
◉ What is true about infection control in radiography?
Answer: When using a digital sensor, use a barrier before
inserting the sensor in the patient's mouth.
◉ What should be done before x-ray procedures?
Answer: Obtain informed consent.
◉ What is true about radiation exposure from digital x-rays?
Answer: The radiation exposure from a digital full mouth series
