Question 1

what is the main goal of paediatric dentistry

Answer 1

a child should reach adulthood with an intact permanent mention, with no active caries, as few restored teeth as possible and a positive attitude toward their future dental care

Question 2

what are the operative differences between children and adults

Answer 2

developmental maturity and behaviour
constant change
developing dentition
operator access
tooth size and shape
preventative care
choice of restoration

Question 3

what to ask to get a history of pain from a child

Answer 3

where is the pain
what does the tooth feel like
how long has the tooth been painful
does anything make it better or worse
are you kept awake
spontaneous or precipitated
relieved with analgesics or antibiotics

Question 4

what is the sequence of restoration for children

Answer 4

prevention
fissure sealants
preventative restorations
simple fillings
fillings requiring local anaesthetic but not into the pulp
pulpotomies (upper arch first)

Question 5

which fillings would not require local anaesthetic

Answer 5

minimal cavities with hand excavation or limited caries removal with a slow speed handpiece

Question 6

describe the max dosing of lidocaine

Answer 6

4.4mmg/kg.
10th of a cartridge per kg
2.2ml cartridge has 44mg of active agent

Question 7

describe the max dosing of prilocaine with felypressin

Answer 7

6mg/g.
2.2ml cartridge has 66mg active agent

Question 8

key features of primary central incisor

Answer 8

root may bend distally
mesial edge of crown tends to be straighter

Question 9

key features of primary canine

Answer 9

mesial edge is straighter with the distal flaring out soon after the acj

Question 10

65 morphology

Answer 10

two buccal roots, prominent transverse ridge
one palatal root

Question 11

85 morphology

Answer 11

3 buccal cusps similar to permanent first molar

Question 12

64 morphology

Answer 12

prominent mesiobuccal tubercle

Question 13

84 morphology

Answer 13

prominent mesiobuccal tubercle

Question 14

describe cavity design for primary molars

Answer 14

the occlusal portion should not be greater than 1.5mm
includes all pits and fissures, but preserves the transverse ridge unless this has been undermined by caries

Question 15

notes for occlusal prep in 55 or 65

Answer 15

follow the shape of the distal fissure to create a banana shaped fissure
same with mesial fissure to create a kidney shaped cavity
transverse ridge should not be compromised

Question 16

describe the notes for occlusal cavity prep

Answer 16

cavity no wide than the width of the bur along the depth of the occlusal fissure pattern
1.5mm depth
squiggle cavity
small round bur and slow speed to remove carious dentine
burs held at right angles to the surface of the tooth to prevent sloping of the cavity walls
