Lecture 1- Intro Flashcards
The first component radiographic interpretation including differential diagnosis is:
Proper imaging technique
In terms of differential diagnosis, we need both knowledge and experience including:
- vision
- cognition
- image interpretation
Proper imaging technique includes:
- manual
- cerebral
What can be seen in the following image?
mesodens
Radiographic description includes:
- single vs. multiple
- location
- relative proximity to adjacent structure
- size in dimensions
- outline (well demarcated vs. diffuse) (corticated vs. non-corticated)
- density (radiolucent, radiopaque, or mixed)
non-corticated:
does not have a radiopaque lining
corticated:
lesion has a radiopaque lining
If a lesion is radiolucent, what does this mean about the tissue that makes it up?
mostly soft tissue
If a lesion is radiopaque, this signifies:
mineralization
How do we describe the QUANTITY of a lesion?
- Single vs. Multiple
- Unilateral vs. Bilateral
How do we QUALIFY a radiograph?
- Location
- Size
- Relative Proximity to adjacent strucutres
- Outline
When QUALIFYING a radiograph, how might you describe the LOCATION?
- right vs. left
- anterior vs. posterior
- localized to area of dental arch
When QUALIFYING a radiograph, how might you describe the SIZE?
- dimensions in mm
(diameter, length, greatest dimensions)
When QUALIFYING a radiograph, how might you describe the RELATIVE PROXIMITY (DIMENSIONS) TO ADJACENT STRUCTURES?
- supplements the measurement
When QUALIFYING a radiograph, how might you describe the OUTLINE?
- well demarcated vs. diffuse
- smooth vs. irregular
- corticated vs. non corticated
When QUALIFYING a radiograph, how might you describe the DENSITY?
- radiolucent vs. radiopaque vs. mixed
- mild, moderate, or intense
Allows you to include and/or exclude disease processes based on an educated assessment of the process:
Differential diagnosis
For differential diagnosis, what type of information can you gather and analyze?
- history
- clinical findings (specific/unique signs & symptoms)
- Lab data
Oral radiology descriptive lesion groups include: (11)
- Periapical radiolucencies
- Pericoronal radiolucencies
- Inter-radicular or solitary radiolucencies
- Multilocular radiolucencies
- Ragged radiolucencies
- Generalized rarefactions
- Mixed radiolucent-radiopaque lesions
- Periapical radiopacities
- Solitary radiopacities
- Generalized radiopacities
- Radiopacities outside the jaws
Radiolucencies around the corn of impacted teeth:
pericoronal radiolucencies
- 58 year old male
- no sensitivity or pain
- no swelling or tissue changes
- further testing determines teeth are WNL
What can be noted when looking at this image?
- edentulous patient
- atrophic maxillary alveolar ridge
- Lesion
Location: right side of mandible/ inferior border
Density: radiolucent
Outline: well-demarcated
Quantity: single, unilocular
If a lesion is located in the alveolar bone, it may be more of an:
If its in the basal bone, its may be more likely to be:
odontogenic tumor
non-odontogenic (unless extending from alveolar bone)
Presents:
- 58 year old male
- no sensitivity or pain
- no swelling or tissue changes
- further testing determines teeth are WNL
Clinical Findings:
1. edentulous patient
2. atrophic maxillary alveolar ridge
3. Lesion
Location: right side of mandible/ inferior border
Density: radiolucent
Outline: well-demarcated
Quantity: single, unilocular
Differential Diagnosis?
- Stafne cyst
- Gorlin cyst (calcifying odontogenic cyst)
- Ossifying fibroma
- Neurofibroma
- Calcifying epithelial odontogenic tumor
