Q

How should we position a dorsoventral view in a dental rad?

A

Base of head needs to be pushed down so entire mandible is in contact with the plate

Q

(T/F) You only need to use one lateral view shot to get upper and lower incisors in rabbits.

A

False - often is need separate lateral views of upper and lower incisors to get the full length on film

Q

What views do you want to use in guinea pigs to see the occlusal surfaces on one side and flat occlusal plane on the other side?

A

Isolated DV and 40 oblique

17
Q

What are you looking for in dental radiographs to see if there is disease?

A

Looking for asymmetry

18
Q

What are some signs of asymmetry in dental radiographs?

A

Elodont teeth parallel and of similar length with no interdigital space
Changes in parallel alignment or variations in cheek teeth length
Irregular occlusal plane
Improper alignement of upper and lower jaws
Malalignment of upper and lower incisors
Change in apical bone with lysis or expansion of apical pocket

19
Q

What are the imaginary lines in rabbits, guinea pigs, chinchilla and degu in attempt to create standardize measurement?

A

Bohmer Crossley Reference lines

20
Q

Which views can be used for rats and mouse for dental rads?

A

Laterolateral and dorsoventral often suficient

21
Q

What view can be used in rats and mouse to help with TM evaluations?

A

Rostrocaudal

22
Q

Why is it hard to visualize roots from the cheek teeth in rat and mouse?

A

Anelodont cheek teeth have multiple small roots

23
Q

(T/F) Rats have lower incisors that wrap completely under cheek teeth to caudal mandible.

A

True

24
Q

What is a different view that we can do to carnivores and omnivores (ferrets, sugar gliders and primates) that is different?

A

Can do intraoral films similar to cats since they can open their mouth wide

25
Q

What two structures would you see in herbivores in whole body rads?

A

Large cecums or colons that obscure other organ details

25
Q

What are the standard views for small mammal whole body rads?

A

Laterolateral and dorsoventral views

26
Q

Many herbivores have significant (gas/ food contents) in areas of the GI tract and there is wide variation to normal

A

Gas

27
Q

What structure would you be able to see with a rabbit in a full body rad with GI distension?

A

Can see the duodenum

28
Q

If in a rabbit whole body rad the cranial part of the heart in a thorax view is lost, what can this tell you?

A

Rabbit has a thymoma

29
Q

In a whole body guinea pig rads what is different than a rabbit?

A

They look more bloated (hard to see other structures which is normal and air should be in the stomach)
