1b anatomical nomenclature

Question 1

tori and exostoses

Answer 1

• exophytic growths of normal compact bone

- may become symptomatic if thin overlying mucosa is traumatically ulcerated

Question 2

exostoses

Answer 2

buccal + palatal

Question 3

torus palatinus

Answer 3

midline of the hard palate, common in asian and inuit population, females 2:!

Question 4

tori mandibularis

Answer 4

• mandible lingual to canine/pre-molars
• 90% bilateral
• prevalence in 5-40%

Question 5

exostoses

Answer 5

facial aspect of alveolar ridge

Question 6

stafne bone defect

Answer 6

focal concavity of cortical bone on lingual surface

Question 7

fordyce granules

Answer 7

• ectopic sebaceous glands

- yellow papules most commonly on buccal mucosa or lips

Question 8

linea alba

Answer 8

linear white plaque typically along buccal mucosa at the occlusal plane
-clenching or bruxing

Question 9

morsicatio

Answer 9

chronic mucosal chewing

Question 10

***leukoedema

Answer 10

• generalized gray opalescence of the mucosa
• most commonly involves buccal mucosa
• common in smokers, african americans (70-90% adults; 50% children)
• disappears when mucosa is stretchee

Question 11

varicosities (varices)

Answer 11

prominent veins most often seen on the ventral and lateral tongue
67% of adults >60

Question 12

median rhomboid glossitis

Answer 12

flat/slightly raised erythematous rhomboid area of midline dorsal tongue
-etiology unclear (developmental vs. infectious)

Question 13

benign migratory glossitis***

Answer 13

• geographic tongue/erythema migrans
• common immune-mediated condition
• 1-3% of population
• one or more erythematous patches incompletely bordered by yellow-white peripheries
• involves dorsal, lateral, or ventral tongue
• ectopic geographic tongue seldem seen

Question 14

benign migratory glossitis

Answer 14

topical benedryl or steroid may be considered for rare symptomatic cases

Question 15

fissured tongue

Answer 15

associated with benign migratory glossitis

Question 16

hairy tongue**

Answer 16

• not to be confused with hairy leukoplakia or with candidiasis
• coated appearance of dorsal tongue due to keratin (elongation of filiform papillae)

Question 17

circumvallate papillae

Answer 17

linear arrangement of prominent papules of posterior dorsal tongue

Question 18

torus palatinus

Answer 18

midline of the hard palate

Question 19

tori mandibularis

Answer 19

mandible lingual to canine/premolars

Question 20

stafne bone defect

Answer 20

developmental defect containing portion of salivary gland

Question 21

fordyce granules

Answer 21

yellow , ectopic sebaceous glands, not salivary glands

Question 22

stafne bone defect

Answer 22

developmental defect containing portion of submandibular gland
