Q

Enostoses

A

Well defined dense RO areas

18
Q

Osteoma

A

Circumscribed sclerotic masses

19
Q

Dentigerous cyst

A

Unilocular RL with well defined corticated borders
Pericoronal to impacted tooth, attached to CEJ

Can cause root resorption or displacement of adjacent structures/teeth

20
Q

Odontogenic keratocyst

A

Well-defined RL with corticated smooth-scalloped margins

Multilocular or unilocular

Expands in AP direction, less likely to cause root resorption, displacement and expansion

21
Q

Lateral periodontal cyst

A

Small, well-defined unilocular RL between roots of 2 vital teeth

Can be multilocular if its the polycystic variant

22
Q

Nasopalatine duct cyst

A

Oval/pear/heart shaped unilocular RL

Midline between roots of CI

23
Q

Simple bone cyst

A

RL with well defined but irregular edges

Interradicular scalloping

24
Q

Stafne bone defect

A

Sharply circumscribed oval RL beneath IAC

25
Q

Fibrous dysplasia

A

Expansile lesion
Ground glass appearance
Blending/diffuse/ill-defined borders

RL/mixed/RO but typically RO
Anatomic expansion

26
Q

Focal/periapical osseous dysplasia

A

Early stage: RL like PARL, can be single or multiple, can coalesce

Mixed stage: mixed, RL outer rim

Late/mature stage: RO with RL rim

Possible loss of lamina dura and variable effects on PDL space

27
Q

Florid osseous dysplasia

A

Usually bilateral and in both jaws

Epicenter apical to teeth and above IAC

Well defined RL/mixed/RO +/- corticated border

Cotton wool appearance

May be multilocular

28
Q

Ossifying fibroma

A

Well defined RL/mixed/RO +/- corticated border, encapsulated with RL rim

Concentric growth/expansion, displaces IDN, teeth, can cause root resorption and loss of lamina dura

28
Q

CGCG

A

Well defined RL, often with thin or missing cortication
Can be ill-defined in maxilla

Usually anterior mand

Fine granular bone or wispy septa

Unilocular or multilocular

Expands in uneven/undulating pattern, cortical plates may be thinned or destroyed

29
Q

Cherubism

A

Multifocal bilateral expansile multilocular well-defined and corticated RL, with posterior epicenter and wispy internal septa

Massive expansion and tooth displacement towards anterior midline

30
Q

Paget’s disease

A

Multifocal
Bone enlarging
Cotton wool
Hypercementosis

31
Q

Buccal bifurcation cyst

A

buccal bifurcation of mand 1st molar > 2nd molar

may see periosteal reaction

32
Q

Nevoid basal cell carcinoma syndrome

A

Multiple OKCs

33
Q

SCC

A

Ill defined, non corticated, irregularly shaped RL

Destruction of cortical boundaries, irregular widening of PDL, loss of lamina dura

Possible pathologic fractures

34
Q

Osteosarcoma

A

Ill-defined, non corticated, irregularly shaped RL/mixed/RO

Internally granular, sclerotic, cotton ball, wispy or honeycomb shaped

Irregular PDL space widening, loss of lamina dura, possible root resorption, destruction of surrounding structures

Soft tissue mass effect

Periosteal reactions possible (sunray, codmans triangle)

35
Q

Multiple myeloma

A

Multiple well-defined non-corticated RL “punched out” circular/oval lesions

May coalesce to give multilocular appearance

Thinning/destruction of surrounding cortical boundaries

Loss of lamina dura and follicular crypts

36
Q

Lymphoma/leukemia

A

Ill-defined non-corticated with infiltrative extensions, usually RL

Can be multifocal, usually takes on shape of host bone

Can be multilocular if coalescent

Destruction of surrounding structures, lamina dura, PDL space widening, loss of cortical crypts, displacement in occlusal direction

Uncommonly get periosteal reaction

37
Q

Burkitt Lymphoma

A

Rapid growth
Floating teeth
Periosteal reactions

38
Q

Metastasis

A

Can be bilateral

Moderately well to ill defined

Non corticated, usually RL

Breast and prostate cancer can be RO, stimulating periosteal reaction

Destruction of surrounding structures

Can widen PDL spaces, cause loss of lamina dura, mimicking PA lesions

39
Q

Langerhans cell disease

A

Single or multiple

Moderately well-defined but non corticated

Smooth or irregular

Punched out or scooped out appearance with epicenter at midroot

Floating tooth

Possible periosteal reaction
