A

X-ray will turn out darker

19
Q

What are the indications/advantages to using Occlusal radiographs?

20
Q

What are the types of occlusal radiographs?

A

Cross-section
Lateral cross-section
Anterior topographical

21
Q

When taking a cross-section of the maxilla, what should you have?

A

65-70 degree
Bridge of nose

22
Q

When taking a lateral cross-section of the maxilla, what should you have?

A

55-60 degree
Posterior maxilla

23
Q

A

55-60 degree
¼ to ½ in above tip of nose

24
Q

A

Perpendicular to plate
Between mand molars

25
What should the occlusal exposure settings be?
1 or 2 settings higher than PA maxillary
26
What should you do for pediatric occlusal radiographs?
Same protocol Use size 2
27
This is use as an image enhancer to reduce amount of radiation scatter in skull radiographs
Grid
28
This is when you are facing sideways against the grid
Lateral cephalogram
29
What is the difference between a cephalogram and a cephalometric radiograph?
Cephalometric = soft tissues It is a fixed distance
30
This is used for taking measurements and evaluating the effect of growth or disease on a skeletal profile
Lateral cephalometric radiograph
31
What is the standard focal distance for lateral cephalometric?
60 in
32
This is best used for orthodontic and orthognathic surgical treatment
Lateral cephalometric radiograph
33
This is a posterior to anterior skull radiograph. Facing the grid
PA Skull
34
Can you see the sphenoid sinus in the PA skull?
No
35
This is when you're facing the grid with your chin up
Water (occipitomental) skull
36
This is when you’re facing towards the beam with your chin up
