composite shit

Question 1

when to not use composite

Answer 1

operating field not dry

high caries activity

Question 2

what do you need to confirm before starting

Answer 2

tooth is vital

need to see PA to confirm no RL

Question 3

what does CCCL recommend as far as rubber dams

Answer 3

all posterior composites

Question 4

why is partial excavation better than complete caries removal

Answer 4

less pulp exposures? no evidence in signs or symptoms of pulpal disease btw partial caries removal and total removal

Question 5

if tooth is vital and asymptomatic….

Answer 5

stop excavating after you are 75% through dentin to avoid pulp exposure

Question 6

what is vitrebond liner

Answer 6

RMGI liner

Question 7

is vitrebond indicated for direct pulp capping

Answer 7

no

Question 8

what do you do if you have a pulp exposure

Answer 8

cover with CaOH

put vitrebond over that

Question 9

optibond is special bc

Answer 9

It is 15% filled with 0.4 micron fillers so It is more viscous

Question 10

how long to apply opti

Answer 10

15 seconds, air for 5, light cure for 20

Question 11

t/f darker shades take longer to polymerize

Answer 11

t

Question 12

when is It ok to perform incomplete caries removal

Answer 12

deep cavity w high risk of pulping
positive response to cold test
absence of spontaneous pain
absence of pain during percussion
absence of PA RL

Question 13

when to not use liner under composite

Answer 13

when cavity is shallow, thick dentin is the best protection

Question 14

what is gluma

Answer 14

5% glutaraldehyde and 35% HEMA in water, reduces hypersensitive of dentin

Question 15

how does gluma work

Answer 15

occludes tubules

Question 16

when do you use gluma

Answer 16

under amalgam instead of varnish

reduce sensitivity of exposed roots

Question 17

do you need gluma under composites

Answer 17

NOOOOOpe
