Q

how to do a caries clinical exam?

A

visual

  • dry teeth, good light, sharp eyes
  • ortho separators
  • caries detector dyes
  • lasers

Q

how does FOTI work?

A

light doesnt travel through caries only healthy tooth

20
Q

what are orthodontic separators used for?

A

to see interproximally

21
Q

what should you consider when evaluating the dentition?

A
tooth restorable
parent/px compliance
stage dental development
space management
anticipated difficulties
overal prognosis
22
Q

why is stabilisation used?

A
prevent pain
preventive therapy
arrest restorable lesions
acclimatisation
decrease bacterial load in mouth
improve OH by making areas easier to clean
23
Q

what co-operation issues can children have?

A

emotional maturity, fears, previous bad experience, behavioural problems, ability

24
Q

why should you consider stage of development when treating?

A

primary teeth may be close to exfoliation
extractions could be part of ortho plan
space maintenance

25
Q

why is caries pattern important?

A

indicated level of caries activity

26
Q

what is caries prognosis dependant on?

A

preventive issues and motivation

27
Q

why consider space maintanence?

A
effect of premature loss of primary teeth
depends on 
-tooth size/jaw relation
-muscle behaviour
-age at loss
-tooth
loss of 1st perm molars
crowding
28
Q

give examples of space maintainers

A

band and loop

distal shoe

29
Q

what are the results of early primary extractions?

A

crowding, tendency for space loss

greater space loss earlier removed

30
Q

how to balance/compensate extractions in primary teeth

A

balance primary canines to prevent centre line shift

balance of 1st molars if arch crowded

31
Q

what are the consequences of loosing upper FPM’s?

A

loss before complete eruption of 7 = rotation

& mesial movement 7 and distal drift of 5

32
Q

what are the consequences of loosing lower FPM’s?

A

loss after optimum age = tilting 7’s

loss before optimum age = 5 drifts distally and rotates

33
Q

what does relief of symptoms depend on?

A

nature of the pain
status of pulp
stage of dental development
level of px compliance

34
Q

pain history questions for a child

A
where is the pain
what does the tooth feel like
how long has the tooth been painful
does anything make the pain better or worse
keet px awake?
spontaneous or precipitated eg eating
relieved with analgesics/antibiotics
35
Q

when should you prescribe antibiotics?

A

systemic illness
pyrexia
facial swelling

36
Q

what are the emergency tx options?

A
caries excavation and sedative dressing
pulp therapy
drainage of pus
extraction 
-LA +/- IHS
-GA
37
Q

what age is IV sedation considered for?

A

12 and over

38
Q

how can you ensure pain free LA?

A

topical
warm LA cartridge
lower 6s (>6yrs) use IDB
intra-papillary infiltration avoids palatal injection

39
Q

how does a rubber dam increase safety?

A

prevents:
damage to soft tissues
risk of inhalation
cross-infection

40
Q

how does a dam benefit operator and px

A
isolation and moisture control
retraction of gingivae and cheeks 
effective inhalation sedation
px confidence
operator confidence
41
Q

sequence of restoration

A
fissure sealants
preventive restorations
simple fillings
eg. shallow cervical cavities
fillings requiring LA but not into pulp
-upper arch first
pulpotomies/pulpectomies
extractions
42
Q

what are the methods of caries removal?

A
hand excavation
rotary instruments
chemo-mechanical removal
air abrasion
lasers
43
Q

what are the anatomical features of primary crowns?

A
shorter
narrower occlusal tables
thin enamel and dentine
broad contact areas
enamel rods in gingival 1/3 extended occlusally
marked cervical constrictions
whiter
44
Q

where is the clinical significance of primary crown anatomical features

A

limited room for cavity prep
clinical caries only detected if large- bitewings needed
enamel at floor of box not undermined
retention of ss crown

45
Q

what are the anatomical features of primary pulp and why is it significant?

A

large- limited room for caivty prep

pulp horns close to surface - pulp exposure easy

46
Q

what are the anatomical features of primary roots and why are they significant?

A

narrow mesio-distally, long, slender, flared

pulpectomy more difficult
