Introduction to Radiology Flashcards
Radiography
imaging using x-rays to view internal form of an object.
A beam of x-rays and electromagnetic radiation are produced by an x-ray generator which is projected towards the object
Dental radiology
a series of images of teeth, jaw and structures of the skull used to diagnose and treat dental disease.
If you can not see 3rd molars on a bitewing where else can you see them?
On a PANO
Phosphor plates
Similar to film, must be dropped in a processor in order to process the image
Who is able to remain in the room while taking an x-ray on a patient?
No one, only exception is child’s parent if the parent lays with the child with an apron on as well.
Periapical radiograph
includes entire tooth and crown, root and at least 2mm of bone above and beyond the apex.
Bitewing (interproximal) radiograph
shows equal portion of the crown of the upper and lower teeth.
1/3 of the alveolar crest of the bone
can identify periodontal issues
identify interproximal carries
Panoramic radiograph
mandibular and maxillary arches and their supporting structure.
2-dimensional view of half circle from ear to ear
Radiopaque
white, light, bright
-metal restorations
-enamel
-dentin
-lamina dura
-cortical bone
Radiolucent
dark on the images
-air space
-foramen
-canal
-suture
fossa
-pdl space
-soft tissue
Density
overall darkness or lightness of a processed radiograph.
When not enough vertical angulation is used which causes lengthening of the image.
elongation
When too much vertical angulation is used and the image appears to be shortened on the radiograph
Foreshortening
Mental foramen
located between the mandibular premolars
