Case study
Your colleague is viewing a full mouth series of radiographs that he just finished mounting. As he is describing the following features, see if you can tell him the name of the anatomic landmark
1. A dense, vertical radiopacity separating two paired oval radiolucencies observed in the maxillary anterior region.
2. Large, paired oval radiolucencies separated by a dense, vertical radiopacity observed in the maxillary anterior region.
3. A thin radiolucent line resembling a fracture observed between the maxillary central incisors.
4. A round or pear-shaped radiolucency observed between the maxillary central incisors.
5. A broad, U-shaped radiopacity observed superimposed over the maxillary posterior teeth roots.
6. A radiopaque downward projection of bone that appears pointed or hooklike observed in the far posterior region of the maxilla.
7. A large triangular-shaped radiopacity observed superimposed over the maxillary tuberosity region.
8. A large radiolucency outlined by a thin radiopaque border that is observed in almost all the periapical radiographs of the maxilla, from the canine posteriorly.
9. A very small, round radiolucency observed in the midline apical (below) the mandibular incisors.
10. A horizontal radiopaque line extending from the premolar region to the symphysis.
11. A round radiolucency that resembles an abscess observed near the apex of the mandibular second premolar.
12. A horizontal radiopaque line observed in the mandibular posterior region, superimposed across the molar roots.
13. Another horizontal radiopaque line observed in the mandibular posterior region, but inferior to (below) the line described in #12 above. This line is observed inferior to the molar roots.
14. A large, irregularly shaped radiolucency observed inferior to the line described in #13 above.
