Q

ADVICE FOR PARENTS WHEN A TOOTH IS AVULSED

A 
keep tooth in milk or saliva
don't allow tooth to dry out
if there's debris - run under cold water for 10 seconds holding crown 
don't touch the root 
reimplant it quickly

tooth separation

can be before hall crown

80
Q

floss them in and then see patient 3-5 days later

should fall out or be taken out

81
Q

RULES TO GET A HALL CROWN

A

no pupal involvement = xray

sufficient tissue left to retain crown

82
Q

WHAT SHOULD THE FIT OF A HALL CROWN BE

A

below the gingival margins / below margins of cavitation

83
Q

HALL CROWN PROCEDURE

A 
choose crown
try in 
GI luting cement 
dry tooth 
crown over tooth palatal to buccal 
partially seat and either hold with finger / let child bite in it and hold for 2-3 mins 
remove cement from margins
84
Q

WHY MUST THE HALL CROWN BE HELD FOR 2-3 MINS

A

to prevent any springing back which would remove GIC from margins and reduce effective seal

85
Q

WHAT TO REASSURE PARENT AND CHILD ABOUT AFTER PREFROMED METAL CROWN

A

gingiva which is normal and will adjust
meant to be tight
used to it in 24hours
occlusion adjusts in a few weeks

86
Q

STAINLESS STEEL CROWN TECHNIQUE TOOTH PREP

A

remove contact - knife edged
reduce occlusally 2mm - no more than 5mm
smooth corners

87
Q

WHAT PLIERS ARE USED TO CONTOUR SS CROWNS

A

crown crimping pliers

88
Q

COMMON PROBLEMS WITH PREFORMED METAL CROWNS

A

rocking - crown not fitting tooth - adjust prep
canting - uneven reduction of occlusal surface
loss of space - not enough space

89
Q

MINOR FAILURES OF PREFORMED CROWNS

A

new/secondary caries
filling or crown lost/ needs intervention
restoration lost but restorable
reversible pulpitis treated without pulpotomy / extraction

90
Q

MAJOR FAILURES OF PREFORMED CROWNS

A

irreversible pulpitis or abcess = pulpotomy / extraction
filling lost tooth unrestorable
interradicular radiolucency

91
Q

SPLIT DAM TECHNIQUE

A

floss clamp
clamp tooth
2 holes 1cm apart - scissors to connect them
dam over clamp - hold anteriorly with widget
frame

92
Q

WHAT TO CONSIDER WHEN DECIDING IF YOU SHOULD RESTORE A TOOTH OR NOT

A

longevity and cooperation

93
Q

TYPES OF SPACE MAINTAINERS

A

band and loop - when tooth lost early

distal show retainer

94
Q

WHAT DOES HYPOMINERALISED MEAN

A

disturbed enamel formation - all the enamel is present but has lesser mineral content - looks different

95
Q

WHAT DOES HYPOPLASTIC MEAN

A

normal mineral content but not all enamel there

96
Q

EFFECT OF MIIH ON THE PULP

A

more BV - bring immune cells
more immune cells
more nervous tissue

97
Q

CLINICAL EFFECT OF MIH

A

loss of tooth substance has greater effect : tooth wear, secondary caries, breakdown enamel
sensitivity
appearence

98
Q

WHAT TYPES OF PAIN ARE ASSOCIATED WITH MIH

A

central sensitisation
dentine hyper sensitivity
peripheral sensitivity - pulp

99
Q

CAUSE OF MIH

A

unknown - but critical point of enamel development = 1st year of life so consider
pre-natal - preeclampsia / gestational diabetes
perinatal - birth trauma
post natal - prolonged breast feeding / childhood infections

100
Q

HOW TO TREAT MIH MOLARS

A

comp/GI restorations
SS crowns
adhesively retained copings
extract

101
Q

WHY SHOULD LOWER 6S WITH BAD MIH BE REMOVED AGE 8.5-9.5

A

as this is when there is calcification of the 7s bifurcation = 6s removed and 7s will tip into 6 place and look normal
doesn’t matter when in uppers it will just happen

102
Q

HOW TO TREAT MIH INCISORS

A 
acid pumice microabraison 
resin infiltration
external bleaching 
localised comp placement 
combination of above 
full veneers in composite - change to porcelain when 20 and ging margin calmed down
103
Q

WHAT IS THE JAW RELATIONSHIP AT BIRTH

A

gum pads separated anteriorly - cant close mouth

tongue touches lip - changes

104
Q

WHAT ARE THE 5 FACTORS IN THE PSYCHOLOGY OF A CHILDS DEVELOPMENT

A 
social 
cognitive 
motor 
language 
perceptual
105
Q

WHAT ARE THE 4 STAGES OF A CHILDS COGNITIVE DEVELOMENT

A

sensorimotor
preoperational thought
concrete options
formal operations

106
Q

WHAT IS A DENTALLY RELEVANT DISORDER OF SPEECH AND LANGUAGE

A

cleft lip/palate : cleft speech

107
Q

WHAT ARE THE FEATURES OF CLEFT SPEECH

A

oro-nasal fistula
velopharyngeal incompetence
nasal emission, articulation and resonance

108
Q

HOW IS CELFT SPEECH TREATED

other surgeries 
different bottle teets 
articulation therapy 
communication support 
input modelling 
early intervention
109
Q

THINGS TO DO WITH A CHILD IN DENTAL SURGERY

A 
explain 
validate their feeling but try to move forward with them 
give them control 
be empathetic 
get the parent involves - sit on knee 
language alternatives 
give them a chnace to speak
110
Q

WHEN WORKING OUT AGE OF A CHILD BASED ON PICTURES WHAT TO LOOK FOR

A 
FPMS =6
incisors lower = 6
incisors upper 1 lower 2 =7 
incisors upper 2 = 8
lower canine = 9

112
Q

WHICH CLEFT CAN BE BILATERAL/UNILATERAL
