metal jtarget jin jan jx-ray jtube.
j

d. a jbranch jof jmedicine jthat jdeals jwith jthe juse jof jx-rays.
ANSWER: j A

ANSWER: j D
An joral jexamination jwithout jdental jimages jlimits jthe jpractitioner jto jwhat jis jseen jclinically.
jMany jdental jdiseases jand jconditions jproduce jno jclinical jsigns jand jsymptoms. jDental jimagesjare

ja jnecessary jcomponent jof jcomprehensive jpatient jcare. jMany jdental jdiseases jare jtypically

a. Increased jpatient jradiation jexposure
b. Increased jpatient jcomfort
c. Increased jspeed jfor jviewing jimages
d. Increased jchemical jusage
ANSWER: j C
Patient jexposure jis jreduced jwith jdigital jimaging. jDigital jsensors jare jmore jsensitive jto jx-rays
jthan jfilm. jDigital jsensors jare jrigid jand jbulky, jcausing jdecreased jpatient jcomfort. jThe jimage

jfrom jdigital jsensors jis juploaded jdirectly jto jthe jcomputer jand jmonitor jwithout jthe jneed jfor

jchemical jprocessing. jThis jallows jfor jimmediate jinterpretation jand jevaluation. jThe jimage jfrom
