Q

why are elderly patients more liekly to get root caries?

A

had teeth for longer = increased change of having disease at some point = shrinkage occuring = increased root exposure = vulnerable to caries

Q

A patient with medium caries risk is due their annual bitewings but they had a dpt taken for ortho 6 months ago. what do you do?

A

wait 6 months and take bitewings

17
Q

most common type of caries in a deciduous tooth?

A

occlusal

18
Q

why does caries spread quicker in a deciduous tooth?

A

it does not have as far to go to reach the ADJ

19
Q

define rampant/acute caries

A

rapidly occurring caries affecting several teeth

20
Q

rampant caries can be called nursing bottle caries if on what surfaces?

A

the labial surfaces

21
Q

what is the clinical appearance of an active white spot lesion?

A

white and chalky with a loss of lustre (shine)

22
Q

what is the clinical apperance of an inactive white spot lesion?

A

white or brown with a glossy surface

23
Q

how does enamel caries progress?

A

in an EPISODIC fashion

24
Q

arrested root surface caries will look…

A

very dark and hard

25
Q

why are bitewings essential?

A

visual exam is only 50% of approximal caries

26
Q

what are the 2 things that happen to protect the pulp-dentine complex when caries reaches dentine?

A
  1. bacterial toxins elicit pain by moving through dentine tubules and evoke an inflammatory reaction in pulp (pulpitis)
  2. reactionary (tertiary) dentine forms which decreases the permeability of the tubules and allows the pulp to retreat
27
Q

when will you get acute pulpitis?

A

when the pulp is exposed to caries

28
Q

pulp exposed to caries leads to….

A

pulp necrosis which releases toxins (irriversible pulpitis)

29
Q

toxins from the pulp necrosis spread where? causing what?

A

the apex of the root which causes periradicular periodontitis or apical periodontits

30
Q

what is periradicular periodontitis?

A
  • pain and inflammation of the periodontium at the root at the root of the tooth
31
Q

what is the aim of restoring a cavity?

A

to remove any bacterial infection before carious exposure of the pulp

32
Q

how can pulpitis be resolved?

A
  • complete caries removal and restoring with non irritant material and resolution of pain
33
Q

what are the two types of pulpitits?

A
  1. reversible

2. irriversible

34
Q

what is cellulitis?

A

localised blood poisoning giving a swelling of the mouth and facial soft tissues due to a spread of infection and inflammation across the facial planes

35
Q

what is ludwig angina? how does it carry a risk of death?

A

a progression of severe cellulitis

causing an elevated tongue > asphyxiation

36
Q

what is primary root caries?

A

caries on root surface that has no inital involvement of adjacent enamel or restorations

37
Q

what is secondary root caries?

A

caries on root surface adjacent to an existing restoration
