response?
j
a. Anoral examination withdental images limitsthepractitioner towhat is seen

d. Manydental diseases are typicallydiscovered onlythrough the use of dental j j j j j j j j j j j
images.
j
ANSWER: D j
An oral examination without dental images limits the practitioner to what is seen clinically. Many
j j j j j j j j j j j j j j
dental diseases and conditions produce no clinical signs and symptoms. Dental imagesare a necessary
j j j j j j j j j j j j j j j

4. Thex-raywas discovered by
j j j j
a. Heinrich Geissler j
b. WilhelmRoentgen j
c. Johann Hittorf j
d. WilliamCrookes j
ANSWER: B j
Heinrich Geissler built thefirst vacuum tubein 1838. Wilhelm Roentgen discovered the
j j j j j j j j j j j j
x-ray on November 8, 1895. Johann Hittorf observed in 1870 that discharges emitted from the
j j j j j j j j j j j j j j
negative electrode of a vacuum tube traveled in straight lines, produced heat, and resultedin a
j j j j j j j j j j j j j j j j
greenish fluorescence. William Crookes discovered in the late 1870s that cathode rays werestreams

j j j j j j j j j
a. Increased patient radiation exposure j j j
b. Increasedpatient comfort j j
c. Increased speed forviewingimages j j j j
d. Increased chemicalusage j j
ANSWER: C j
Patient exposure is reduced with digital imaging. Digital sensors are more sensitive to x-rays than
j j j j j j j j j j j j j j
film. Digital sensors are rigid and bulky, causing decreased patient comfort. The image from digital
j j j j j j j j j j j j j j j
