Flashcards in 2 Deck (20):
1

Resistance form

resists fracture

2

Defensive dent.

reparative

3

primary and secondary

formative original dentin

4

Liners

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.

5

Copal varnish

amalgam solution liner - most often - 2-5microm.

6

Adhesive

vitrabond - solution liners - 2-5microm

7

Suspension liners

20-25microm, any liner based on H20 and have their constituents suspended instead of dissolved - CaOH

8

Cement liners

200-1000 microm, GI

9

Eugenol liners

ZOE and B+T

10

Dentin bonding systems/sealers

optibond solo plus, gluma

11

IF RDT more than ------- no liner needed

2mm. For younger patients, maybe need a liner here.

12

How many layers for copal varnish

2 layers, 85% sealed. 1 layer is 55% sealed

13

Copalite absolutely can only be used with

amalgam

14

Bases

thicker - 1-2mm - mostly thermal and mechanical protection/support. Provides resistance to amalgam condensation.

Should be about a mm thick at least for strength.

15

Liner used to seal off all

exposed dentin (can put liner above base)

16

Indirectpulp cap

15 days have defensive reparative cells differentiate.
30 days - microscopic reparative dentin
100 days radiographic reparative dentin.

Class V is less important (pressure).

17

Heavy hemorrhage in pulp means

affected pulp, more likely to need endo.

18

IF you get saliva on pulp exposure

increase likelihood of endo.

19

ZOE cannot be used under

composite.

20

Use dentin conditioner for

RMGI - blue liquid for dentin only.
