21
Q

-58yo male
-no sensitivity or pain
-no swelling or tissue changes surrounding teeth in this quadrant
-further testing determines teeth are WNL

What can be noted upon looking at this pano?

A
  1. edentulous patient
  2. atrophic maxillary alveolar ridge
  3. lesion

22
Q

If a lesion is located in alveolar bone it may be more of a _____ but if its in basal bone its more likely to be _____

A

alveolar- odontogenic

basal- more likely to be nonodontogenic (unless its extending from alveolar bone)
