Chapter 20- Bisecting Technique Quiz

What are the two methods for taking PA's?

• Paralleling and Bisecting

• Paralleling and Occlusal

• Paralleling and Bitewing

• Bisecting and Bitewing

Why must one know both Paralleling and Bisecting techniques?

• Because one technique may not work on all patients

• Because one technique is faster than the other

• Because one technique is less expensive than the other

• Because one technique is more accurate than the other

What is the central portion of the primary beam of x-radiation called?

• Primary ray

What is the principle of the Bisecting Technique based on?

• Dividing the angle formed by the receptor and the long axis of the tooth into two equal parts

• Dividing the central beam into two equal parts

• Dividing the receptor into two equal parts

• Dividing the tooth into two equal parts

Where should the receptor be placed along the tooth in the Bisecting Technique?

• Lingual side

• Distal side

• Mesial side

• Buccal side

What is the imaginary line that bisects the angle formed by the receptor and the long axis of the tooth called?

• Bisector

• Tangent

• Parallel

• Perpendicular

In the Bisecting Technique, how should the central beam be directed?

• Perpendicular to the receptor

• Perpendicular to the bisector

• Parallel to the receptor

• Parallel to the long axis of the tooth

What can cause foreshortened images in the Bisecting Technique?
