L1- Intro Flashcards
The first component to radiographic interpretation including differential diagnosis is:
proper imaging technique
In terms of differential diagnosis we need both knowledge & experience including:
- vision
- cognition
- image interpretation
Proper imaging technique includes:
- manual
- cerebral
What can be seen in the following image?
mesiodens
Radiographic description includes:
- single vs. multiple
- location
- relative proximity to adjacent structures
- size in dimensions
- outline (well demarcated vs. diffuse) (corticated vs. non-corticated)
- density (radiolucent, radiopaque, mixed)
if lesion has a radiopaque lining:
corticated
if lesion does not have a radiopaque lining:
non-corticated
If a lesion is radiolucent, it is likely made of:
mostly soft tissue
If a lesion is radiopaque, this signfies:
mineralization
How do we describe the QUANITY of a lesion?
- single vs. multiple
- unilateral vs. bilateral
How do we QUALIFY a radiograph?
- Location
- Size
- Relative proximity to adjacent structures
- Outline
When QUALIFYING a radiograph, how might you describe LOCATION?
-right vs. left
-anterior vs. posterior
-localize to area of dental arch
When QUALIFYING a radiograph, how might you describe SIZE?
-dimensions in mm (diameter, length, greatest dimensions)
When QUALIFYING a radiograph, how might you describe RELATIVE PROXIMITY (DIMENSIONS) TO ADJACENT STRUCTURES?
-supplements the measurements
When QUALIFYING a radiograph, how might you describe OUTLINE?
-well demarcated vs. diffuse
-smooth vs. irregular
-corticated vs. non-corticated
When QUALIFYING a radiograph, how might you describe 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 a differential diagnosis, what type of information can you gather & analyze:
- history
- clinical findings (specific/unique signs & symptoms)
- lab data
Oral radiology descriptive lesion groups include:
- 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 crowns of impacted teeth:
Pericoronal radiolucencies
-58yo male
-no sensitivity or pain
-no swelling or tissue changes surrounding teeth in this quadrant
-further testing determines teeth are WNL
What can be noted upon looking at this pano?
- edentulous patient
- atrophic maxillary alveolar ridge
- lesion
-location: right side of mandible/inferior border
-density: radiolucent
-outline: well-demarcated
-quanity: single, unilocular
If a lesion is located in alveolar bone it may be more of a _____ but if its in basal bone its more likely to be _____
alveolar- odontogenic
basal- more likely to be nonodontogenic (unless its extending from alveolar bone)
PRESENTS:
-58yo male
-no sensitivity or pain
-no swelling or tissue changes surrounding teeth in this quadrant
-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
-quanity: single, unilocular
Differential diagnosis?
- Stafne cyst
- Gorlin cyst (calcifying odontogenic cyst)
- Ossifying fibroma
- Neurofibroma
- Calcifying epithelial odontogenic tumor
