If the patient's head is tipped down, the mandible will appear how?
like it is 'smiling' dramatically
If the patient's head is tipped up, the mandible will appear how?
like it is 'frowning' dramatically
The palate will overlap the maxillary roots most often when the patient's head is tilted (up/down)
down
If the mandible has a dramatic "smiling" orientation, what feature may be eliminated?
condyle
If the patient is slumping over, what might be superimposed on anterior region of film?
cervical spine
Low density and low contrast films are typically caused by errors during ___ or (over/under) exposure
processing, under
If the developer is too concentrated, you will get (light/dark) films
dark
Overexposure leads to (dark/light) films
dark

Operator opened it in white light
What is the error here?
chemical contamination
What is the error here? (notice the RO line indicated by the red arrows)
