1

What is the mid-palatal suture?

Thin, radioLUCENT line between maxillary centrals extending from anterior aspect of maxilla to posterior aspect of palate

2

What structure appears as thin radiolucent lines about roots of maxillary incisors

Floor of the nasal fossa

3

What is the nasal septum comprised of, and where might you see it?

Cartilage and the vomer bone, above central incisors

4

What represents the most anterior point on the maxilla

Anterior nasal spine

5

What structure is an ovoid radiolucency between maxillary incisors

Incisive foramen

6

Concavity in maxilla between roots of lateral and canine, bone is thinner here

Lateral fossa

7

Floor of nasal fossa and wall of maxillary sinus, useful in edentulous patients

Lateral canine area

8

How do the medial, inferior, and lateral walls of the maxillary sinus show up on images

Thin radioPACITIES

9

Where will you find the malar process of the zygoma?

Over the roots of the maxillary 1st molar

10

What are vertical radiopaque lines arising from the floor of sinus?

Sinus septations

11

How does the posterior superior alveolar canal show up on maxillary radiographs

Horizontal radiolucent bands

12

Where will you find the maxillary tuberosity?

Posterior to the 3rd molar

13

When might you see the nasolabial fold?

On Premolar Film when the patient's mouth is slightly open

14

What type of PA might you see the coronoid process of the mandible?

Maxillary Molar PAs

15

Where might you see the Oblique Ridge of the Mandible?

It crossed the mandibular 2nd or 3rd Molar at the CEJ

16

Where might you see the internal oblique ridge?

Crossing the mandibular 2nd or 3rd molars at the apicies

17

This structure will appear as a radiolucent band of uniform width, below roots of mandibular molars

Mandibular canal

18

This ovoid radiolucency will be located inferior to the 1st or 2nd premolar (or between them) where 90% of mandibular nerves exit the jaw

Mental Foramen

19

How many genial tubercles are there?

4: 2 Inferior and 2 Superior

20

Where will you find the genial tubercles

Surrounding the radiolucent lingual foramen

21

This radiolucency is apical and interradicular to mandibular central incisors

Lingual foramen

22

If the film has a prominent submandibular fossa, where would you find it

Inferior to the internal oblique ridge

23

These are radiolucent lines in interdental bone, they are the site of neurovascular bundles feeding teeth

Nutrient canals
