procedures

Question 1

function of silver diamine fluoride?

Answer 1

prevent caries
relieve dentinal hypersensitivity

Question 2

features of silver diamine fluoride?

Answer 2

colourless
odourless
liquid

Question 3

what does SDF contain?

Answer 3

silver
ammonium
fluoride ions

Question 4

pH of SDF?

Answer 4

10.4

Question 5

purpose of silver in SDF?

Answer 5

antimicrobial

Question 6

purpose of fluoride in SDF?

Answer 6

remineralisation of enamel and dentine
preventing and arresting dental caries

Question 7

why does SDF stain oxidisable surfaces?

Answer 7

formation of silver oxide layer

Question 8

what is ART?

Answer 8

atraumatic restorative treatment

selective caries remover using only hand instruments and placement of GIC restoration

Question 9

when would you use ART?

Answer 9

single surface cavities in primary and permanent teeth

caries into dentine but still a clear band of dentine between lesion and dental pulp

cooperation limited

Question 10

how do you prepare a cavity for ART?

Answer 10

establish clear peripheral margins with sharp hand instrument (excavator)

Question 11

what can be used to separate teeth?

Answer 11

orthodontic separators

Question 12

when would you place a separator?

Answer 12

prior to fitting a metal crown using Hall technique

aid caries diagnosis through visualisation and access to proximal contacts

when placing proximal sealants

Question 13

what does Hall technique eliminate?

Answer 13

caries removal
tooth prep
LA

Question 14

when would you use the Hall technique?

Answer 14

multi-surface lesions OR non-cavitated lesion into dentine
no clinical/ radiographic signs of pulpal pathology
clear band of dentine between cavity and pulp

temporise 1st permanent molars (until time of extraction)

Question 15

in the hall technique, what is the crown loaded with?

Answer 15

GIC luting cement

Question 16

when would you restore an anterior primary tooth with a crown form?

Answer 16

significant substance loss or caries

Question 17

what is the aim of cavity prep?

Answer 17

establish clear peripheral margins around carious lesion
provide adequate depth required for material being used
no caries in dentino-enamel junction

Question 18

why do you leave caries on the floor of the cavity?

Answer 18

preserve pulpal health
maintain integrity of tooth structure
facilitate retention and function of material

Question 19

what material should be avoided with multisurface cavities?

Answer 19

GI

Question 20

what is a pulpotomy?

Answer 20

inflamed and possibly infected coronal pulp tissue is removed from carious primary tooth to preserve healthy radicular pulp

Question 21

when is a pulpotomy indicated?

Answer 21

in a tooth with signs/ symptoms of irreversible pulpal inflammation

or

radiographically there is no normal appearing dentine separating the pulp tissue from a carious lesion

tooth must not have any clinical or radiographic signs of infection or peri radicular periodontitis

Question 22

function of rubber dam?

Answer 22

protect airway
increase pt comfort
reduce chance of bacterial ingress
enhance moisture control

Question 23

when would it be assumed that the pulp is non vital?

Answer 23

no bleeding occurs when access to pulp has been gained

Question 24

what happens if you find out that the pulp is non vital?

Answer 24

pulpectomy or extraction

Question 25

how is haemostasis achieved during pulpotomy?

Answer 25

cotton pellet soaked in ferric sulphate

Question 26

what is placed after haemostasis is achieved in pulpotomy?

Answer 26

small amount of mineral trioxide aggregate (MTA)

Question 27

what is pulp chamber filled with in pulpotomy?

Answer 27

zinc oxide eugenol material

Question 28

what differs a traditional stainless steel metal crown technique to the hall technique?

Answer 28

less conservative as it requires occlusal reduction and sometimes proximal preparation to provide space for crown

also requires LA

Question 29

When would you use a traditional stainless steel metal crown technique?

Answer 29

following pulpotomy
to reduce occlusal loading
when no time to place separators
