CLASSIFICATIONS OF CARIES Flashcards
how are caries classified
according to:
location, rapidity/severity, extent, tissue involvement, occurence, surfaces involved,
these caries are found in the pits and fissures
pit and fissure caries
what type of relationship in the pits and fissure caries
base to base relationship
in pits and fissures:
enamel base:
enamel apex:
towards DEJ: towards outer surface of enamel
where are pits and fissure seen
molars, premolars, lingual surfaces of Mx incisors
smooth surfaces caries relationship
apex to base
apex of dentin is located at?
towards the pulp
smooth surface caries are seen on?
lingual, mesial, buccal surfaces
how are smooth caries diagnosed?
using an explorer
- if there is a catch in the proximal areas
- lesions are chalky white, opaque, rough spot
occur on the tooth root that has been exposed to the oral environment and habitually covered with plaque
root caries
classifications according to rapidity
acute and chronic
commonly seen in children becuase of wide dentinal tubules
acute or rampant caries
what does acute caries lesion look like?
light brown and dull
it affects many teeth and very rapid clinical course
acute or rampant caries
pain is not usually associated in rampant caries T or F
F- pain is seen because dentin is involved
it runs longer clinical course
chronic, arrested, slow caries
waht does chronic caries lesion look like?
dark, eburnated, hard, shiny
what age group is chronic caries is usually seen?
old aged patients
these caries are first time caries
primary caries
caries are due to previous occurence or after a restorative procedure
secondary caries
caries are usually seen adjacent or below the restorative material
secondary caries
recurrent caries are:
a. caries that appear for the first time
b. caries that are intentionally or accidentally left
c. caries developing from previously affected tooth
b
microleakage is seen in what type of caries
secondary caries
when caries appear to be chalky white with no enamel breakage they are called?
incipient caries
incipient caries cannot be remineralized T or F
F - they can still be remineralized
are caries that are not reversible
cavitated caries
involves half of enamel but not the DEJ
moderate caries
involves the DEJ and more than half the distance to the pulp
severe caries
involves DEJ and less than half the distance t the pulp
advanced caries
involves less than half the thickness of enamel
incipient caries
tissue involvement;
enamel, dentin, cementum
when more than 2 surfaces are invovlved
complex caries
when 2 surfaces are involved
compound caries
these are lesion found in the dentin that are dark brown and shiny
dentinal inactive lesion
these are lesion found in the dentin that are light brown and dull
dentinal active lesion
how many classification of caries according to GV black
6
it involves caries in the proximal surfaces of posterior teeth
class II
involves proximal surfaces of anterior teeth with no incisal angle involvement
class III
proximal surface of anterior teeth with incisal angle involvement
class IV
cusp tips of posterior teeth
class VI
involves caries in the incisal edge
class VI
pits and fissure caries
class I
father of modern dentistry
greene vardiman black
gv blacks classification includes depth T or F
F
more mineral content
radiopaque
radioluscent
appear dark, less mineral content
no caries seen in readiograph
e0
outer 1/2 of enamel
e1
inner third of dentin
d3
inner 1/2 of enamel
e2
middle third of dentin
d2
outer 1/2 of dentin
d1
how many point scale according to WHO
4 point
clinically detectable enamel lesion with intact surfaces
d1
no enamel breakdown
d2
lesion extending to the pulp
d4
enamel breakge with dentin involvement
d3
