MULTIPLE |CHOICE

1. Radiation |is |defined |as
a. a |form |of |energy |carried |by |waves |or |streams |of |particles.
b. a |beam |of |energy |that |has |the |power |to |penetrate |substances |and |record |image
shadows |on |a |receptor.
|

c. a |high-energy |radiation |produced |by |the |collision |of |a |beam |of |electrons |with |a
metal |target |in |an |x-ray |tube.
|

d. a |branch |of |medicine |that |deals |with |the |use |of |x-rays.
ANSWER: | A
Radiation |is |a |form |of |energy |carried |by |waves |or |streams |of |particles. |An |x-ray |is |a |beam |of
|energy |that |has |the |power |to |penetrate |substances |and |record |image |shadows |on |a |receptor.

X-radiation |is |a |high-energy |radiation |produced |by |the |collision |of |a |beam |of |electrons |with |a
|metal |target |in |an |x-ray |tube. |Radiology |is |a |branch |of |medicine |that |deals |with |the |use |of

x-rays.

correct |response?
|

a. An |oral |examination |with |dental |images |limits |the |practitioner |to |what |is |seen
|clinically.

b. All |dental |diseases |and |conditions |produce |clinical |signs |and |symptoms.

, c. Dental |images |are |not |a |necessary |component |of |comprehensive |patient |care.
d. Many |dental |diseases |are |typically |discovered |only |through |the |use |of |dental
images.
|



ANSWER: | D
An |oral |examination |without |dental |images |limits |the |practitioner |to |what |is |seen |clinically. |Many
|dental |diseases |and |conditions |produce |no |clinical |signs |and |symptoms. |Dental |images|are |a

|necessary |component |of |comprehensive |patient |care. |Many |dental |diseases |are |typically

4. The |x-ray |was |discovered |by
a. Heinrich |Geissler
b. Wilhelm |Roentgen
c. Johann |Hittorf
d. William |Crookes
ANSWER: | B
Heinrich |Geissler |built |the |first |vacuum |tube |in |1838. | Wilhelm |Roentgen |discovered |the
x-ray |on |November |8, |1895. |Johann |Hittorf |observed |in |1870 |that |discharges |emitted |from |the
|negative |electrode |of |a |vacuum |tube |traveled |in |straight |lines, |produced |heat, |and |resulted|in |a

|greenish |fluorescence. |William |Crookes |discovered |in |the |late |1870s |that |cathode |rays |were

|streams |of |charged |particles.

a. Otto |Walkoff
b. Wilhelm |Roentgen
c. Edmund |Kells
d. Weston |Price
ANSWER: | C
Otto |Walkoff |was |a |German |dentist |who |made |the |first |dental |radiograph. |Wilhelm |Roentgen
|was |a |Bavarian |physicist |who |discovered |the |x-ray. | Edmund |Kells |exposed |the |first |dental

|radiograph |in |the |United |States |using |a |live |person. | | |Price |introduced |the |bisecting |technique |in

|1904.

8. Which |of |the |following |is |an |advantage |of |digital |imaging?
a. Increased |patient |radiation |exposure
b. Increased |patient |comfort
c. Increased |speed |for |viewing |images
d. Increased |chemical |usage
ANSWER: | C
Patient |exposure |is |reduced |with |digital |imaging. |Digital |sensors |are |more |sensitive |to |x-rays
|than |film. |Digital |sensors |are |rigid |and |bulky, |causing |decreased |patient |comfort. |The |image

|from |digital |sensors |is |uploaded |directly |to |the |computer |and |monitor |without |the |need |for

|chemical |processing. |This |allows |for |immediate |interpretation |and |evaluation. |The |image |from
