when describing lesions on an xray, what are the 7 things you must comment on?
- site
- size
- shape
- margins
- internal structure
- effect on adjacent anatomy
- number
Describing lesions, what falls under:
SITE?
where is it? (alveolar bone, area of jaw, spine? skull?)
Relationship with a nearby structure?
Describing lesions, what falls under:
SIZE
- measure dimensions
- describe boundaries
Describing lesions, what falls under:
Shape?
General:
- rounded
- scalloped
- irregular
Locularity:
- unilocular
- pseudolocular
- multilocular
Describing lesions, what falls under:
Margins?
Well defined &:
a. corticated
b. non-corticated
Poorly defined &:
c. blending into adjacent tissues
d. ragged edges
not applicable to radiopacities
Describing lesions, what falls under:
Internal structure?
What makes jaw lesions RADIOLUCENT (dark)?
- resorption/decrease mineralisation of bone
- replacement of bone with abnormal tissue
What makes jaw lesions RADIOPAQUE (brighter)?
- increased thickness of bone
- osteosclerosis of bone (increase in density/mineralisation)
Describing lesions, what falls under:
Involvement of tooth (if any)
Describing lesions, what falls under:
effect on adjacent anatomy?
what is idiopathic osteosclerosis?
localised area of increased bone density - unknown cause
what is sclerosing osteitis?
localised area of INCREASED bone density in response to inflammation
what is hypercementosis?
excessive deposition of cementum around root
