Question 18

What do you see here?

Answer 18

• soft-tissue/fluid opacity (most likely fluid)
  
  • Follow the mitchell marker’s beads and draw a line
  • any lines that are parallel to the beads will be fluid falling because of gravity

Question 19

what is seen here?

Answer 19

fluid at both lines

Question 20

what is seen here

Answer 20

• molar 1 is disease
  
  • Decreased in opacity
  • The shape of the root is blunted, rounded, compared to the others
  • Opacity is half of what the others are
  • High probability that the tooth abnormality is associated with the sinus abnormality
