Within Normal Limits

3

What is checked in an extraoral exam?

-general appearance
-head
-skin

4

What does "AWNN" stand for?

Apparently Well, Normally Nourished

5

What is evaluated when checking general appearance?

Look for abnormalities in: posture, gait, breathing, facial symmetry, swelling, nasal discharge

6

What is evaluated when checking skin?

Look for abnormalities in: color and lesions (if lesions, document location and size)

7

What is evaluated when checking eyes?

Look for abnormalities in:
-sclera (should be white and clear)
-conjunctiva (should not be red/irritated)
-pupil (should not be excessively dilated or small)

8

How is the TMJ evaluated?

Palpate TMJ anterior to tragus and have patient slowly open and close. Note any deviations, deflections, or crepitus.

9

What are the characteristics of an infectious/inflammatory lymph node?

-soft to palpation
-freely movable
-painful

10

What are the characteristics of a malignant lymph node?

-firm to palpation
-fixed
-generally not tender or painful

11

What does "NPNT" stand for and when is it used?

Non-Palpable, Non-Tender
describes normal lymph nodes

What is checked in an intraoral exam?

-mucosa (labial and buccal)
-palate
-tonsils/oropharynx
-tongue
-floor of mouth
-salivary glands
-alveolar processes
-gingiva
-teeth/occlusion

13

What are the four types of papillae on the tongue?

filiform, foliate, circumvallate, and fungiform

14

What are the top 3 most commonly missing adult teeth? (partial anodontia)

1. third molars (especially maxillary)
2. maxillary lateral incisors (1-2% of the population)
3. mandibular second premolars (1%)

15

What is the most commonly missing primary teeth?

mandibular central incisors

16

On which dentition and in which arch is it more common for extra or supernumerary teeth to occur?

permanent dentition in the maxillary arch (90%)

17

What are the three common areas for extra or supernumerary teeth to occur?

-maxillary incisor area
-third molar area
-mandibular premolar area

18

A small extra maxillary incisor is located on the midline between the 2 central incisors. What is this tooth called?

mesiodens

19

What are the 3 terms that can be used to describe an extra molar?

paramolar, distomolar, or fourth molar

20

If there is an extra mandibular premolar in the arch, is it more likely to erupt facial or lingual to the arch?

If it is not in the arch, an extra mandibular premolar is likely to erupt lingual to the arch.

21

If there is an extra mandibular canine in the arch, is it more likely to erupt facial or lingual to the arch?

If it is not in the arch, an extra mandibular canine is likely to erupt facial to the arch.

22

What tooth's crown is the most variable?

third molars

23

What tooth is the most likely to be peg-shaped?

maxillary lateral incisors (peg-shaped maxillary central incisors are very rare)

gemination

25

Identify this anomaly.
One crown appears double in width with two roots, two pulp chambers, and two pulp canals.

fusion (two adjacent crowns fused); most common in primary anterior

26

Identify this anomaly.

Hutchinson's incisors (congenital syphilis)

27

What disease are mulberry molars a result of?

syphilis

28

Identify this anomaly.
a third (middle) lingual cusp is present on mandibular molars

tuberculum intermedium

29

Identify this anomaly.
an additional distal cusp is present on mandibular molars

tuberculum sextum

30

Identify this anomaly.
similar to an extra lingual cusp; may have its own pulp horn
