Understanding Panoramic Radiography

Which of the following best describes a panoramic X-ray?

• A two-dimensional dental X-ray that captures the entire mouth in a single image

• A three-dimensional scan of the jaw using cone beam technology

• An intraoral X-ray focusing on a single tooth

• A chest X-ray used to assess lung health

What is the primary purpose of proper patient positioning during a panoramic X-ray?

• To reduce the cost of the procedure

• To ensure clear and accurate images without distortion

• To minimize the time required for the scan

• To avoid the need for protective equipment

Which anatomical structure is typically visible on a panoramic radiograph?

• The femur

• The mandible

• The clavicle

• The scapula

Which of the following is a common dental condition that can be identified on a panoramic X-ray?

• Sinusitis

• Impacted third molars (wisdom teeth)

• Otitis media

• Tonsillitis

What is the recommended safety protocol for patients during panoramic radiography?

• No safety measures are needed

• Wearing a lead apron and thyroid collar

• Removing all jewelry and metallic objects from the head and neck area

• Both B and C

Which of the following errors can result from improper patient positioning during a panoramic X-ray?

• Blurred or distorted images

• Increased radiation exposure

• Reduced image contrast

• All of the above

What is the main advantage of panoramic radiography over intraoral radiography?

• Lower radiation dose

• Ability to visualize the entire dentition and jaw in one image

• Higher image resolution

• No need for patient cooperation

Which of the following is NOT typically assessed using a panoramic X-ray?

• Dental caries in detail

• Jaw fractures

• Cystic lesions

• Tooth eruption patterns

What is the correct position of the patient’s tongue during a panoramic X-ray?

• Resting at the floor of the mouth

• Pressed against the roof of the mouth

• Hanging out of the mouth

• No specific position is required

Which safety principle is most important in dental radiography?

• ALARA (As Low As Reasonably Achievable)

• Using the highest possible radiation dose

• Taking multiple images for every patient

• Ignoring patient medical history
