Q

What type of lesion?

No radiolucent rim (like mature cemento-osseous dysplasia) and no radiolucent center (like condensing osteitis)

A

Idiopathic osteosclerosis

17
Q

What type of lesion?

Remains static or slow increase in size until maturity; X-Ray follow-up is all that is needed

A

Idiopathic osteosclerosis

18
Q

What type of lesion?

Common, typically asymptomatic, dome-shaped, homogeneous, faintly radiopaque lesion arising from the floor of the Maxillary sinus due to accumulation of inflammatory
(serous) exudate underneath the sinus
mucosa

A

Antral pseudocyst

19
Q

What type of lesion?

Cause is not known; possible adjacent odontogenic infection or sinus lining irritation from sinus infection or allergies

A

Antral pseudocyst

20
Q

What type of lesion?

Tx = rule out odontogenic infection; only treat is there are significant symptoms (expansion, pain)

A

Antral pseudocyst

21
Q

What type of lesion?

Bacteria, foreign material and desquamated keratin accumulation in the tonsillar crypts forms compacted, foul-smelling tonsillar concretion

A

Tonsillar concretions/tonsillolithiasis

22
Q

What type of lesion?

If it calcifies, called a tonsillolith (superimposed on ramus on pano; CBCT can confirm)

A

Tonsillar concretions/tonsillolithiasis

23
Q

What type of lesion?

Causes bad breath (halotosis)
Sensation of something stuck in throat, but otherwise asymptomatic

A

Tonsillar concretions/tonsillolithiasis

24
Q

What type of lesion?

Variable size, single/multiple, unilateral/bilateral
Not acutely painful, but can predispose to recurrent tonsillar infection leading to pain or abscess

A

Tonsillar concretions/tonsillolithiasis

25
Q

What type of lesion?

Tx = if symptomatic, remove with saltwater gargling or waterpik, enucleation/curettage, laser cryptolysis, or tonsillectomy

A

Tonsillar concretions/tonsillolithiasis

26
Q

What type of lesion?

Benign osseous tumor, affecting membranous bone

A

Osteoma

27
Q

What type of lesion?

Painless, slowly enlarging
Paranasal sinus involvement is common

A

Osteoma

28
Q

What type of lesion?

Jaw lesions are associated with condylar area and lingual posterior mandible

A

Osteoma

29
Q

What type of lesion?

Exophytic mass on bone surface (periosteal) stimulating a tori/exostoses

A

Osteoma

30
Q

What type of lesion?

Intramedullary growth (endosteal or central) similar to end stage inflammatory process (condensing osteitis) or sclerotic bone (idiopathic osteosclerosis)

A

Osteoma

31
Q

What type of lesion?

Histologically identical to tori, condensing osteitis, or idiopathic osteosclerosis, but with continual growth

A

Osteoma

32
Q

What should you always rule out if you see an Osteoma?

A

Gardner syndrome

33
Q

What type of lesion?

Autosomal dominant

A

Gardner syndrome

34
Q

What type of lesion?

Mutation in adenomatous polyposis coli (APC) tumor suppressor gene

A

Gardner syndrome

35
Q

What type of lesion?

One of the multiple intestinal polyposis syndromes

A

Gardner syndrome

36
Q

What type of lesion?

Characterized by osteomas of facial bones, skin lesions like epidermoid cysts/desmoid tumors, supernumerary teeth, or odontomas

A

Gardner syndrome

37
Q

What type of lesion?

Development of precancerous polyps of the colon

A

Gardner syndrome

38

What type of lesion?

Increased risk of thyroid carcinoma

A

Gardner syndrome
