Question 1

Which dental radiographic technique is most commonly recommended for obtaining full-tooth images including the root apex in small animal patients?

Accepted Answer

Bisecting angle technique

Answer

The bisecting angle technique is the standard method in veterinary dentistry because the curved dental arcades in animals make the parallel technique difficult to apply.

Question 2

What instrument is used to measure periodontal pocket depth during an oral examination?

Accepted Answer

Periodontal probe

Answer

A periodontal probe, marked in millimeter increments, is inserted into the gingival sulcus to measure pocket depth and attachment loss.

Question 3

What does Grade 2 furcation exposure indicate in a dog with periodontal disease?

Accepted Answer

The probe enters the furcation but does not pass through

Answer

Grade 2 (F2) furcation involvement means the periodontal probe enters the furcation but cannot pass all the way through to the other side.

Question 4

What is the primary purpose of using a dental elevator before extracting a tooth in a veterinary patient?

Accepted Answer

To sever the periodontal ligament and luxate the tooth from its socket

Answer

Dental elevators are inserted into the periodontal ligament space to sever ligament fibers and progressively luxate the tooth, reducing the force needed for extraction.

Question 5

Which radiographic finding on a dental X-ray most strongly suggests a periapical abscess in a veterinary patient?

Accepted Answer

Periapical lucency (halo) surrounding the root apex

Answer

A periapical lucency (radiolucent halo) around the root tip indicates bone resorption caused by infection or inflammation at the apex, consistent with periapical abscess.
