Flashcards in 2 Deck (20):
primary and secondary
formative original dentin
almost flowable - barrier for sealing dentin from restorative material. More important with composite than amalgam. Done to prevent leaky tooth restoration interfaces. Also have electric, thermal insulation.
amalgam solution liner - most often - 2-5microm.
vitrabond - solution liners - 2-5microm
20-25microm, any liner based on H20 and have their constituents suspended instead of dissolved - CaOH
200-1000 microm, GI
ZOE and B+T
Dentin bonding systems/sealers
optibond solo plus, gluma
IF RDT more than ------- no liner needed
2mm. For younger patients, maybe need a liner here.
How many layers for copal varnish
2 layers, 85% sealed. 1 layer is 55% sealed
Copalite absolutely can only be used with
thicker - 1-2mm - mostly thermal and mechanical protection/support. Provides resistance to amalgam condensation.
Should be about a mm thick at least for strength.
Liner used to seal off all
exposed dentin (can put liner above base)
15 days have defensive reparative cells differentiate.
30 days - microscopic reparative dentin
100 days radiographic reparative dentin.
Class V is less important (pressure).
Heavy hemorrhage in pulp means
affected pulp, more likely to need endo.
IF you get saliva on pulp exposure
increase likelihood of endo.
ZOE cannot be used under
