Will appear as a white area around the crown |
enamel
|
|
the grayish-white area that is semi-radiopaque and forms the bulk of the tooth
|
dentin
|
|
this boundry is distinct due the different densities and opacities
|
DEJ
|
|
radiolucent (appears radiographically as a dark area)
|
pulp
|
|
normally you DON'T see this on an xray (it is very thin and has the same radiodensity and dentin)
|
cementum
|
|
thin, dark line that circumscribes the tooth)
|
periodontal ligament space
|
|
dense bone that surrounds the root; appears as a white line
|
lamina dura
|
|
continuous with the lamina dura that is the coronal most part of the alveolar process; appears radiopaque |
alveolar crest
|
|
dense outer layer of bone; appears radiopaque; examples are inferior border of mandible, lamina dura of alveolus, alveolar crest
|
cortical bone ("compact bone")
|
|
composed of trabeculae (radiopaque) and marrow spaces (radiolucent); located between the lamina dura of adjacent teeth and multirooted teeth
|
cancellous bone ("spongy" bone) |
|
|
mylohyoid ridge |
|
|
zygomatic process, appears as a J or U shaped radiopaque line above max molars |
|
|
maxillary tuberosity |
|
|
coronoid process |
|
|
mental fossa above mental ridge in ant. mand. apex of teeth. Dark vertical lines are nutrient canals |
|
|

|
septa of maxillary sinus |
|
|
inverted Y, maxillary sinus and nasal sinus |
|
|
nutrient canals |
|
|
Hamulus. Most patients you will not go back this far. You can also see the coronoid process. |
|
|
mental ridge |
|
|
mental foramen. Btwn first and second premolars, |
|
|
external oblique ridge |
|
|
Internal oblique ridge |
|
|
submandibular fossa inferior to the mylohyoid ridge |
|
|
posterior alveolar ridge |
|
|
anterior alveolar crest |
