TV4101 - Dental - Radiology

Indications for radiographic assessment of the oral cavity

Indications (continued)

• TMJ pathology/jaw #s

• Pre/post tooth extraction

• RCT

• Oligodontia/supernumerary teeth

• Tooth development and breed soundness

What this?

Draining the sinus below the eye - dc indicates a dental issue

What this?

Ass. with?

Cutaneous sinus possibly associated with premolar or
molar tooth

Whole mouth screening radiographs

How many views?

Standard screen film and standard X-ray unit

CT imaging

Uses?

Standard screen film and standard X-ray unit

• Tube head- vertical & horizontal angulation

• Intraoral views of rostral mandible/maxilla

• Extraoral lat. Obliques (30-45 degrees from horizontal)- too much

distortion/ superimposition

• Good for TMJ radiographs

CT imaging

• Useful for tumour management and complex pathology

Dental film and dental X-ray unit

Features?

Angulation?

Uses?

Fixed KVp and mA, variable time

Vert/Horiz angulation

Sizes 2 and 4 most common film sizes (size 4 film 3X larger than size 2 film)

What view this?

Good for viewing what?

Gold standard TMJ view

What view this?

Film and tube head positioning for introral views

What position is this?

Parallel technique

What this?

Why do?

How do?

Bisecting Angle technique can lead to?

Better to be more vertical than horizontal to avoid elongation

Bisecting angle technique - maxillary PMs

Special Techniques - What view is this?

Used for what?

Special Technique - What is this?

How to do?

Intended effect?

Cats have a large zygomatic arch - a normal 45 degree view from the lateral will cause zygomatic arch to superimpose over the teeth

30 degrees to horizontal fixes that issue by making the teeth “longer” but zygo goes higher

What is happening here?
