Image Interpretation Descriptive Terminology Flashcards
interpretation
an explanation of what is viewed on a dental image
diagnosis
the identification of disease by examination or analysis
dental radiographer examines each intraoral images for what
unerupted, missing and impacted teeth
dental caries and pulp cavities
bony changes, level of alveolar bone, calculus
roots and periapical areas
dental image interpretation/diagnosis checklist
view images quickly for evidence of unerupted or impacted teeth
next, examine caries, pulp size, pulp shape
repeat until all surfaces of teeth and structures are evaluated
documentation
date of exposure
number and type of images
evaluation of diagnostic quality
list of limiting factors, retakes, or additional images needed
documentation: description of teeth
indicate impactions
number anomalies
crown anomalies
defective restorations, caries, calculus, pulpal changes
root abnormalities
others
documentation: bone and supporting structures
indicate PA radiolucencies and radiopacities
bone loss, changes in crestal lamina dura and radicular lamina dura
changes in PDL
furcations
interdental trabecular pattern of bone
lesions
descriptive terminology is used to describe the
appearance, location and size of a lesion
why use descriptive terminology
describes what is seen and uses a common language
eliminates chance for miscommunication, allows for documentation
legal purposes
describing radiographic findings: distribution
the number of anomalies and how they are positioned in hard tissue
single - one lesion
multiple lesions - more than one: localized or generalized
appearance of radiolucent lesions terms
unilocular
multiocular
moth-eaten
multifocal pattern
widened PDL
unilocular radiolucent lesions
one compartment
radiolucent
tend to be small and nonexpansile
have borders that may appear corticated or noncorticated on image
unilocular lesions, corticated borders
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
unilocular lesion, noncorticated borders
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
multilocular radiolucent lesions
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
unilocular radiolucencies example
periapical cyst
periapical granuloma
periapical abscess
multilocular radiolucent lesion example
keratocystic odontogenic tumor
other radiolucent lesions
widened PDL: osteosarcoma
multifocal radiolucencies: multiple myeloma, cherubism
“Moth-Eaten” radiolucencies
multifocal radiolucency: cherubism
many small areas not joined
more than one location
moth-eaten radiolucency
ill-defined, noncorticated radiolucency with ragged borders
early stages of osteosarcoma, squamous cell carcinoma, osteomyelitis, leukemia
periapical location
a lesion located around the apex of a tooth
periapical location: unilocular corticated radiolucent
ex of a periapical granuloma
well circumscribed
rounded around apex
may have thin radiopaque border
tooth is on-vital
inter-radicular location
a lesion located between the roots of adjacent teeth
residual cyst, primordial cyst, traumatic bone cyst
edentulous zone
a lesions located in an area without teeth
some are duplicates of other areas
