1

what are the steps in basic interpretation

shade
localization
periphery and shape
internal structure
mass effects
formulate an interpretation

2

A radiolucent shade is

appearing dark or black radiographically

3

a mixed density shade is

appearing both dark and light radiographically

4

a radiopaque density is

appearing light or white radiographically

5

an epicenter

is an indication as to where the disease started and may help determine the features of growth and tissue origin

6

if epicentre is above the IAC

it is odontogenic in origin

7

if epicentre is below the IAC

non odontogenic in origin

8

if epicentre is in IAC

neuromuscular in origin

9

An epicentre within the dental papilla is indicative of

Leukemia, lymphoma, langerhans cells of histiocytosis

10

this type of border is non corticated and with no bony reactions around the missing bone

punched out border

11

this type of border blends into normal trabecular pattern, but less defined than a corticated border

sclerotic border

12

this is a mixed density entity with a well defined border, but also showing a a radiolucent soft tissue capsule surrounding the mixed density centre of the lesion

soft tissue capsule

13

this border is difficult to determine because where the lesion begins compared to where normal is difficult to tell apart

invasive border

14

what is a true multilocular shape

it contains internal compartments separated by septae

15

circular/ round shaped lesions suggests

mostly of cystic (hydraulic) or potentially tumour growth

16

scalloped border suggests

proliferation of cells (tumbrel growth

17

dystrophic calcifications appear as ______ within a ______ tissue. They are _____ in shape and indicate _______ disease process

radiopacities, radiolucent, irregular, long standing

18

amorphous bone appears as

a radiopaque density
