What is focal osteoporotic marrow defect?
-An area of hematopoietic marrow that produces a radiolucency
What treatment is needed for focal osteoporotic marrow defect?
-No treatment is needed after the dx is established
What is idiopathic osteosclerosis?
-Focal area of increased radiodensity that is of unknown cause and cannot be attributed to anything else
What is condensing osteitis associated with?

What is a bone scar?
-It is where condensing osteitis once was but the tooth was removed and the radio opacity in the bone is still there
