  • Q1
    What is the correct position of the dental x-ray sensor for a periapical image?
    Positioned anywhere in the mouth
    Perpendicular to the long axis of the tooth
    At a 45-degree angle to the long axis of the tooth
    Parallel to the long axis of the tooth
  • Q2
    Which type of digital x-ray sensor is commonly used for taking periapical images in dentistry?
    CCD sensor
    Phosphor plate sensor
    Film-based sensor
    PSP sensor
  • Q3
    What is the recommended vertical angulation when taking a dental periapical x-ray image?
    45 degrees
    0 degrees
    180 degrees
    90 degrees
  • Q4
    What is the purpose of using a dental X-ray beam alignment device during the periapical x-ray procedure?
    To enhance image quality through contrast adjustment
    To reduce radiation exposure to the patient
    To ensure consistency in angulation and positioning
    To provide a comfortable experience for the patient
  • Q5
    Which type of digital image receptor is commonly used in modern digital dental radiography for capturing periapical images?
    Photostimulable phosphor plates
    Digital sensors (such as CMOS or CCD sensors)
    Computed radiography (CR) systems
    Film-based sensors
  • Q6

    180 degrees
    45 degrees
    90 degrees
    0 degrees
  • Q7
    What is the main advantage of using digital dental radiography for periapical imaging compared to traditional film-based methods?
    Faster processing time
    Reduced radiation exposure to the patient
    Higher image resolution
    Greater contrast in images
  • Q8
    What is the purpose of using a beam alignment device in digital dental periapical x-ray imaging?
    To enhance color rendition in the x-ray image
    To provide a magnified view of the tooth structure
    To reduce the exposure time needed for capturing the image
    To ensure proper alignment of the x-ray beam, sensor, and tooth
  • Q9
    In digital dental periapical x-ray imaging, what does FOV stand for?
    Frontal Overlap volume
    Focusing on Vertebrates
    Field of view
    Frame of view
  • Q10
    What is the recommended exposure time for capturing a digital dental periapical x-ray image?
    5 to 10 seconds
    1 to 2 seconds
    15 to 20 seconds
    0.1 to 0.2 seconds
