caries terminology, practical 2

Question 1

nonselective caries removal

Answer 1

1) everything (infected, affected, discolored) is removed
2) even pinpoint caries

Question 2

indirect pulp cap

Answer 2

1) activa

Question 3

direct pulp cap

Answer 3

1) MTA

Question 4

stepwise (two step) caries removal

Answer 4

1) carious tissue is removed and a temp restoration is place
2) months later, remove until firm dentin and permanent restoration

Question 5

selective caries removal

Answer 5

1) carious tissue removed until firm dentin reached

Question 6

caries removal approach

Answer 6

1) moderate and advanced
- typically nonselective is done

Question 7

infected dentin

Answer 7

1) soft mushy, necrotic dentin with bacteria present
2) active infection
3) ONLY leave if you are within 0.5 mm of pulp
- unless they are in pain (then endo)
- or if there is swelling near the root (then endo)

Question 8

affected dentin

Answer 8

1) dry, leathery, demineralized, no bacteria
2) may contain bacterial toxins and acids

Question 9

simple, compound, complex caries

Answer 9

1) one surface
2) two
3) three

Question 10

primary caries

Answer 10

1) first time lesion on that surface

Question 11

recurrent / secondary caries

Answer 11

1) junction of the tooth and restoration
2) microleakage
- seal is not perfect

Question 12

residual caries

Answer 12

1) caries that remains in a completed tooth prep

Question 13

incipieny/ reversible

Answer 13

1) non cavitated
2) remineralizable (ICDAS 1,2…E1, E2)
3) appears white when air-dried and it disappears when wet
- white spot lesion

Question 14

acute/rampant caries

Answer 14

1) rapidly damages tooth structure
2) multiple teeth involved
- light colored and soft
3) bottle caries, substance abuse

Question 15

chronic/slow

Answer 15

1) slowly progression
2) demineralized tooth that is almost remineralized
3) dark, hard, shiny

Question 16

arrested

Answer 16

1) formed and stopped due to local etiological changes that make it no longer retentive to food and it becomes self-cleansing
- brown black, glossy, hard

Question 17

cavitates/irreversible

Answer 17

1) enamel surface is broken (not intact) and usually lesion into dentin
