small tongue
26
Aglossia is frequently associated with what?
mandibular micrognathia

28
Macroglossia presents with what signs?
noisy breathing, drooling, difficulty eating/speaking
29
Macroglossia is most associated with what syndrome?
Beckwith-Wiedmann syndrome

What is ankyloglossia?
short, thick lingual frenum limiting movement of tongue
31
What happens if epithelium doesn't fuse together where the thyroid descended?
A thyroglossal duct cyst
32
Where is ectopic thyroid found?
between foramen cecum and epiglottis
33
When do symptoms of lingual thyroid arise?
puberty, pregnancy, or menopause
34
Fissured tongue is a component of what syndrome?
Melkersson-Rosenthal syndrome
35
What is fissured tongue?
grooves/furrows on the dorsal tongue that are 2-6mm deep
36
Geographic tongue is also known as?
Benign migratory glossitis
37
How does geographic tongue usually present?
Smooth erythematous area with white to yellow rolled border. This pattern constantly shifts
38
What forms hairy tongue?
accumulation of keratin on the filiform papilla on the dorsal tongue
39
What is the most common type of oral varicosity?
sublingual varix
40
What is a phlebolith?
A calcified varicosity on the lip/buccal mucosa
41
What is caliber persistent artery?
A main arterial branch that sits in superficial submucosa without reducing diameter. (*has pulse*)
42
Coronoid hyperplasia will cause a deviation toward which side upon opening?
toward the affected side (because large coronoid can't leave the zygomatic arch area)
43
Condylar hyperplasia will cause deviation to which side upon opening?
Toward the opposite side than affected
44
How do palatal exostoses grow?
laterally on the hard palate
45
How does a palatal torus grow?
down from the palate
46
What is a common exostosis occurring in the midline of the hard palate?
Torus palatinus
47
What is a stafne defect?
Where the mandibular salivary gland makes a depression in the mandible
48
What causes Eagle's syndrome?
Elongated stylohyoid process
49
Define cyst.
Pathologic cavity lined by epithelium
50
How are cysts different from abscesses?
Cysts are fluid filled and abscesses are filled with mostly PMNs, and aren't lined by epithelium
51
What are palatal cysts in newborns?
Epstein's pearls *occur along midline from entrapped epithelium when palatal shelves fused*
52
What are Bohn's nodules?
They're small white or yellow papules along the midline near the jxn of hard/soft palate
53
What is a swelling of the upper lip lateral to the midline that results in elevation of the ala?
Nasolabial cyst
54
In what kind of tissue do nasolabial cysts form?
occurs in soft tissue, but is made of either epithelial remnants or misplaced epithelium from nasolacrimal duct
55
What are the three most common reasons for globulomaxillary radiolucencies?
Radicular cyst (aka periapical cyst), periapical granuloma, and lateral periodontal cyst
56
What is the most common non-odontogenic cyst of the oral cavity?
The Nasopalatine Duct Cyst
57
Do roots resorb during a nasopalatine duct cyst?
Nopers because the cyst is in the duct and not the alveolar ridge
58
What is a cyst of the incisive papilla?
its a nasopalatine duct cyst that can develop in the soft tissues of the incisive papilla with any bony involvement
59
Will teeth remain vital with a nasopalatine cyst? (either in the duct or in the incisive papilla)
Yes the teeth are vital because it's not within the PDL space
60
What is a localized white or yellow nodular, fluctuant, subcutaneous lesion often presenting on the back of adults?
Epidermoid cyst *represents 80% of follicular cysts of the skin*
61
Where do pilar cysts most commonly occur?
On the scalp and derived from hair follicles
