Cavity Lining Materials Flashcards
(6 cards)
1
Q
why would you line a cavity
A
prevent gaps, block undercuts
lining for exposed dentine near pulp as promotes pulpal health
indirect/direct pulp capping
2
Q
cavity lining protects pulp from;
A
chemical stimuli =
unreacted chemicals in filling
thermal stimuli =
exothermic setting, heat conducting metals
bacteria + endotoxins =
microleakage
3
Q
name 4 types of cavity lining materials
A
CaOH
GIC/RMGIC
ZOE
ledermix
RM ZOE
4
Q
explain CaOH
A
non setting
irritates odontoblast layer to form reparative dentine
ca from pulp forms pulp-dentine bridge
high alkaline = bactericidal
5
Q
ZOE as a liner
A
can also be PD dressing or RC sealer
reduces dentine sensation, reduce pulpal pain
INHIBITS COMPOSITE SETTING CONTRA
6
Q
ledermix as a liner
A
treats pulpal inflammation, “hot pulps” pain relief
