Radiography Flashcards
What are radiographs
Images created using X ray photons
The photons pass through an object before interacting with a receptor
What 3 ways can X-rays interact with matter
- transmitted
- absorbed
- scattered
What do radiographic images show
Represents the pattern of attenuation of the X ray photons after they have passed through matter
What does radiolucent mean
- darker areas on the imagine
- less attenuation of X rays
What does radioplaque mean
- lighter areas on image
- more attenuation of x-rays
Why are radiographs used in dentistry
Used to show anatomy and pathology not visible to the naked eye, most commonly to assess caries
What are intra oral receptors
Intra oral receptors are the receptors inside the mouth, they can be used to produce bitewing, periapical and occlusal radiographs
What are extra oral receptors
Receptors used out side the mouth can be used to produce panoramic radiograph
What does bitewing radiography show
Provides a view of multiple side teeth premolars and molars
Shows crowns, part of the root and some interdental bone
What is periapical radiography
Provides a full length view of a particular tooth/teeth, shows crown and entire root, shows height of the bone around the tooth
What is panoramic radiography used for
Provides a zoomed out view of the jaws
What is occlusal radiography
Provides a view of one dental arch allows teeth to be seen from different viewpoints
What is cone beam computed tomography
3D scan
