Lecture 5 Flashcards
Translucent Zone
Zone 1
innermoststrongest churva
Zone 1
Dark Zone
Zone 2
positive zone formed by demineralization
Zone 2
Body of the Lesion
Zone 3
area of greatest demineralization
Zone 3
Surface Zone
Zone 4
outermost
Zone 4
appears relatively unaffected
Zone 4
the greater resistance of the surface layer may be due to a greater degree of mineralization or greater concentration of fluoride in the ____.
Surface Enamel (Zone 4)
means reversible
Incipient
your carious lesions will start as a white spot, but it has no break/cavity yet. So your intact surface zone, this is ____ early enamel caries
incipient
Then you have body of the lesion, there is a little demineralization going on even though your surface is still intact that is why what you see clinically is a ____.
white spot
you have your dark zone and after the dark zone is your ____.
translucent zone (innermost zone)
is the inner recrystallization zone
Zone 1
this is hypercalcified than normal enamel. So it is even stronger than your normal enamel
Zone 1
is also described as the positive zone and this is formed as a result of demineralization
Zone 2
is the area of greatest demineralization so you already have demineralization going in here even though your surface is still intact.
Zone 3
It is still reversible, meaning if this is still happening in the tooth
Incipient
it can still be ____, meaning if you have a white spot, you don’t need to drill it or make cavity prep right away.
remineralization
Zone 5
Infected zone
not sensitive, numerous bacteria, cant
remineralize
Infected zone
Zone 4
Turbid zone
not sensitive to stimuli, numerous bacteria, can’t remineralize
Turbid zone
