ADAP Radiography 2

Question 1

Which radiographic technique is most commonly used for children due to reduced patient discomfort?

Accepted Answer

Bisecting angle technique

Answer

The bisecting angle technique is often preferred for pediatric patients because it requires less film placement depth and causes less gagging.

Question 2

What is the purpose of the lead apron used during dental radiography?

Accepted Answer

To protect the patient from scattered radiation to the torso and gonads

Answer

The lead apron shields the patient's thyroid, chest, and reproductive organs from scatter radiation during X-ray exposure.

Question 3

What does the term 'elongation' describe in dental radiography?

Accepted Answer

An image that appears longer than the actual tooth

Answer

Elongation occurs when the vertical angulation of the X-ray beam is too shallow (less than correct), causing the image to appear stretched or longer than the actual tooth.

Question 4

Which type of dental radiograph provides the most comprehensive view of the entire dentition and surrounding structures in a single image?

Accepted Answer

Panoramic radiograph

Answer

A panoramic radiograph captures the entire maxilla, mandible, teeth, and surrounding structures in one extraoral image.

Question 5

What does kilovoltage peak (kVp) primarily control in dental radiography?

Accepted Answer

The penetrating power (quality) of the X-ray beam

Answer

kVp controls the energy and penetrating ability of the X-ray beam, affecting contrast and the ability to penetrate dense structures.
