3, 4, 5

Question 8

Answer 8

1,2,3,4,5

Question 9

where should forceps be applied?

Answer 9

as far down the root as possible without traumatising gingivae

Question 10

what pressure should be applied when extracting?

Answer 10

apical pressure

Question 11

multirooted teeth ext

Answer 11

figure of 8 and intermittent buccal expansion

- easier to expand than palatal bone

Question 12

single rooted teeth ext

Answer 12

rotational movement

Question 13

post-ext

Answer 13

check tooth to see if apices intact
check socket clear
damp gauze bite 5-10mins

Question 14

luxators role

Answer 14

sever and tear PDL

Question 15

uses of elevators

Answer 15

provide point of application for forceps
loosen teeth prior to using forceps
ext teeth without forceps
removal of multiple root stumps
removal of retained roots
removal of root apices

Question 16

elevator mechanics

Answer 16

create space for forceps: wedge, lever or wheel and axle

Question 17

what are WJ good for?

Answer 17

8s

Question 18

what are Cryers good for?

Answer 18

furcation areas of molars

Question 19

holding elevators and luxators

Answer 19

palm of hand

index finger on shank for support and control

Question 20

when using elevators

Answer 20

support instrument to avoid injury to pt if it slips
direct force away from major structures e.g. antrum, IDC, mental n
direct vision
never use adjacent tooth as fulcrum unless it too is to be extracted
discard as soon as blunt/bent
keep sharp and in good shape
establish logical and effective point of application
avoid excessive force and application points lingually/palatally
after use bone file/drill to remove sharp edges and a Mitchell’s trimmer for removal of ST debris, irrigate with sterile saline into socket and under flap and aspirate to remove debris and check socket empty

Question 21

coupland elevator movement

Answer 21

rotational movement
usually mesial/buccal
working range of blade is a turn through 90 degrees - blade moved from vertical to horizontal

Question 22

tissue forceps

Answer 22

pen grip

Question 23

advantage of monofilament

Answer 23

less likely to facilitate an infection because it is more difficult for bacteria to colonise a single strand

Question 24

disadvantage of polyfilament

Answer 24

often contraindicated in contaminated wounds due to wicking

Question 25

vicryl, velosorb, polysorb

Answer 25

polyfilament, resorbable

Question 26

monocryl

Answer 26

monofilament, resorbable

Question 27

nylon, prolene

Answer 27

monofilament, non-resorbable

Question 28

mersilk, silk

Answer 28

polyfilament, non-resorbable
