List the 6 uses of dental x rays

1. 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

2

what dentist is noted as being the father of x ray production

Conrad Roentgen

3

what was Roentgens wifes name

Bertha roentgen

4

what dentist introduced the bisecting technique

A. Cieszynski

5

the computed tomography type of imaging is most useful for this type of dental case?

complex diagnosis

6

in what year was the first dental xray taken

1896

7

what company made the first dental x ray

Eastman Kodak co

8

what company made the first dental xray machine

General electric

9

the first dental x ray film was made of?

glass photographic plates wrapped in black paper and rubber

10

name 3 primary advantages of utilizing digital imaging vs. conventional x rays

1. 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

11

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

12

early x ray tubes were insulated with what specific oils to prevent over heating

PCB oils

13

Dr William David Coolidge introduced what type of tube for use in x ray machines

hot cathode tube which is more safe

14

this dentist introduced the parraleling technique of radiograph to profession of dentistry

Dr. Franklin McCormack

15

what dentist is credit with convincing dentists that they should use oral radiography in thier practices

dr c edmund kells

16

what important contribution to radiation was made by Dr william herbert rollins

radiation protection

17

what was dr otto walkhoff credited with in the history of radiation production

1st to expose prototype of dental radiograph

18

what was the name of the tube used by roentgen in his discovery of radiation

crookes tube

19

why was the invisible ray called an x ray

the symbol x represented the unknown

20

besides being easier to pronounce; why was radiograph chosen over the term roentgengraph

x ray closely resembles the radio wave

21

dental professionals use the term ------- becasue it is more descriptive and easier to pronounce

radiograph

22

the patient uses what term for roentgengraphs

x rays

23

hazardous early x ray machines existed due to open uninsulated what?

high voltage supply wires

24

which of the early discoveres are from louisisana

C E Kells

25

why is it necessary to have electricity to operate an x ray machine

for sending out x radiation waves quickly and efficiently
