ICDAS: Flashcards
ICDAS stands for
international caries and assessment system
modified caries which include code 1 and code 2
code a
merged categories
sound, initial, moderate, extensive
show no evidence of visible caries
sound surfaces
carious opacity ir visible discoloration
initial stage
localized enamel breakdwon, no dentinal involvement and shadowing
moderate stage
with dentinal involvement, pulp involvement
extensive stage
radiograph of icdas
initial- ra1-3
moderate- rb4
extensive- rc5-6
inner 3rd of dentin
rc5
with pulp involvement
rc6
middle third of dentin
rb4
oter 1/2 of enamel
ra1
inner half of enamel
ra2
outer 3rd of dentin
ra3
initial stage is clinically
code a
moderate stage is clinically
codes 3 nad 4
extensive stage is clinically
codes 5 and 6
if it is rb1-2 radiographically and clinically moderate then it is
moderate
if it is clinically extensive and radiographically extensive then it is
extensive cr
if it is ra3 and clinically initial
moderate or initial
if it is clinically sound and ra3
initial
if it is radiographically extensive no matter what the clinical appearance is, it is automatically extensive T OR F
T
IF it is clinically sound and the radiograph is ra1-2
initial
bigger dentinal involvement
backward caries
bigger enamel involvement
forward caries
what does ICCMS stand for
international caries classification adn management system
what is merged ICDAS
sound, initial, moderate, extensive
what is under modified ICDAS
code A (combination of code 1 and code 2 )
full icdas wherein does not involve the breakage of enamel but shadowing is seen and dentin is involved
code 4
color demarcation on the root surface has no cavitations
code 1
cavitation under code 1 in root caries:
less than .5mm
range of cavity in code 2
more than .5mm but <2 mm fore moderate and morethan 2mm if extensive
code E is used when
root surface cannot be visualize directly even with assistance of gentle air drying
probability of the test giving positive finding when disease is not present
sensitivity
probability of a negative finding when disease is absent
specificity
speed of pregression or rate at which dentition is destroyed by the sum of new caries plus enlarged lesions
caries activity
inherent tendency to be afflicted by caries
caries susceptibility
