Radiology ch 1 Flashcards
List the 6 uses of dental x rays
- detect, confirm, and classify oral diseases 2. detect trauma 3. detect missing or extra teeth 4.evaluate growth and development 5. document the oral condition of patient 6. educate patients about oral health
what dentist is noted as being the father of x ray production
Conrad Roentgen
what was Roentgens wifes name
Bertha roentgen
what dentist introduced the bisecting technique
A. Cieszynski
the computed tomography type of imaging is most useful for this type of dental case?
complex diagnosis
in what year was the first dental xray taken
1896
what company made the first dental x ray
Eastman Kodak co
what company made the first dental xray machine
General electric
the first dental x ray film was made of?
glass photographic plates wrapped in black paper and rubber
name 3 primary advantages of utilizing digital imaging vs. conventional x rays
- reduction of radiating dosage 2. elimination of film and processsing chemistry 3. disposal of film packaging materials such as lead foils and spent time processing chemicals
why have the pointed x ray cones been replaced with open ended cylinders
pointed cones scattered through contact with the material of the cones and they were exposing the patient to unessary radiation
early x ray tubes were insulated with what specific oils to prevent over heating
PCB oils
Dr William David Coolidge introduced what type of tube for use in x ray machines
hot cathode tube which is more safe
this dentist introduced the parraleling technique of radiograph to profession of dentistry
Dr. Franklin McCormack
what dentist is credit with convincing dentists that they should use oral radiography in thier practices
dr c edmund kells
what important contribution to radiation was made by Dr william herbert rollins
radiation protection
what was dr otto walkhoff credited with in the history of radiation production
1st to expose prototype of dental radiograph
what was the name of the tube used by roentgen in his discovery of radiation
crookes tube
why was the invisible ray called an x ray
the symbol x represented the unknown
besides being easier to pronounce; why was radiograph chosen over the term roentgengraph
x ray closely resembles the radio wave
dental professionals use the term ——- becasue it is more descriptive and easier to pronounce
radiograph
the patient uses what term for roentgengraphs
x rays
hazardous early x ray machines existed due to open uninsulated what?
high voltage supply wires
which of the early discoveres are from louisisana
C E Kells
why is it necessary to have electricity to operate an x ray machine
for sending out x radiation waves quickly and efficiently
W. C. Roentgen
Discovered x-rays
Which scientists may have taken the first dental radiograph
Kells
Morton
Rollins
Published “X Ligh Kills,” warning of x-ray dangers
Rollins
SUGGESTED basics for both bisecting and paralleling techniques
W. A. Price
Wrote first dental x-ray textbook
Introduced bitewing radiographs
H.R. Raper
Designed a “long-cone” to use with the paralleling technique
G.M. Fitzgerald
Developed the first dental imaging system called Rado VisioGraphy
Francis Mouyen
What is radiology
the study of x-radiation
What is a radiograph
image or picture produced by x-rays
what is radiography
the making of radiographs by exposing and processing x-ray film
Roentgen ray
an older term given to x-radiation in honor of its discoverer
Which imaging modality will most likely become the gold standard for imaging certain dental conditions in the near future?
cone beam volumetric tomography
became popular in the 1960’s with the intoduction of the panoramic x-ray machine
panoramic radiography
Digital imaging systems replace film as the image receptor with a
sensor
