Q

dental image interpretation/diagnosis checklist

A

view images quickly for evidence of unerupted or impacted teeth

Q

why use descriptive terminology

A

describes what is seen and uses a common language
eliminates chance for miscommunication, allows for documentation
legal purposes

Q

unilocular radiolucent lesions

A

one compartment

Q

unilocular lesions, corticated borders

A

lesions exhibits a thin, well-demarcated radiopaque rim of bone of periphery
benign, slow-growing process
density similar to border of the mandible
often benign

Q

unilocular lesion, noncorticated borders

A

lesions does not exhibit a thin radiopaque rim of bone at periphery
periphery appears fuzzy or poorly defined
may represent either a benign or a malignant process
periapical abscess

Q

multilocular radiolucent lesions

A

exhibits multiple radiolucent compartments
larger than unilocular
expansile: displaces B and L plates of bone
resemble soap bubbles/honeycomb
typically benign lesions w aggressive growth potential

Q

multilocular radiolucent lesion example

A

keratocystic odontogenic tumor

17
Q

other radiolucent lesions

A

widened PDL: osteosarcoma
multifocal radiolucencies: multiple myeloma, cherubism
“Moth-Eaten” radiolucencies

18
Q

multifocal radiolucency: cherubism

A

many small areas not joined
more than one location

19
Q

moth-eaten radiolucency

A

ill-defined, noncorticated radiolucency with ragged borders
early stages of osteosarcoma, squamous cell carcinoma, osteomyelitis, leukemia

20
Q

periapical location

A

a lesion located around the apex of a tooth

21
Q

periapical location: unilocular corticated radiolucent

A

ex of a periapical granuloma
well circumscribed
rounded around apex
may have thin radiopaque border
tooth is on-vital

22
Q

inter-radicular location

A

a lesion located between the roots of adjacent teeth
residual cyst, primordial cyst, traumatic bone cyst

23
Q

edentulous zone

A

a lesions located in an area without teeth
some are duplicates of other areas

24
Q

pericoronal location

A

a radiolucent lesion located around the crown of an impacted tooth

25
Q

location: alveolar bone

A

loss of bone in the max or mand
appears radiolucent
seen in perio disease and systemic illnesses: diabetes, leukemia
also caused by malignant neoplasm

26
Q

alveolar bone loss examples

A

periodontitis
histiocytosis X
cyclic neutropenia
leukemia

27
Q

radiopaque lesions: appearance

A

can be described as: focal opacity, target lesion, multifocal confluent, irregular, ground glass, mixed lucent-opaque

28
Q

focal opacity

A

a well-defined, localized radiopaque lesion on an image
condensing osteitis

29
Q

target lesion: benign cementoblastoma

A

a well-defined, localized radiopaque area surrounded by a uniform radiolucent halo

30
Q

multifocal confluent

A

multiple radiopacities that appear to overlap or flow together
osteitis deformans

31
Q

irregular ill-defined opacity

A

a radiopacity may exhibit an irregular, poorly defined pattern
may represent a malignant condition

32
Q

ground glass opacity

A

a granular or pebbled radiopacity that resembles pulverized glass
resemble an orange peel

33
Q

mixed lucent-opaque lesions

A

both radiopaque and radiolucent
calcifying tumors
radiolucent area w central opaque flecks or calcifications
lesion becomes predominantly radiolucent w radiopaque flecks

34
Q

soft tissue opacity

A

appears as a well-defined, radiopaque area located in soft tissue
calcified lymph nodes, foreign bodies, myositis ossificans

35
Q

radiopaque lesions may appear in the same places as radiolucent lesions such as:

A

periapical
inter-radicular
edentulous
pericoronal location

36
Q

radiopaque: periapical location

A

periapical refers to a radiopaque lesion located around the apex of a tooth

37
Q

radiopaque: inter-radicular location

A

a radiopaque lesion located between the roots of adjacent teeth

38
Q

radiopaque: edentulous zone

A

a radiopaque lesion located in an area without teeth

39
Q

radiopaque: pericoronal location

A

located around the crown of an impacted tooth
usually surrounds entire unerupted tooth (commonly canine)
adenomatoid odontogenic tumor
compound odontoma

40
Q

descriptive documentation radiologically

A

number
size
specific: shape, surrounding tissue, center, margin, expansion, location
