1

used to isolate area of restoration

dental dam or rubber dam

2

prevent saliva from obstructing the procedure, protection against caustic materials, swallowing small objects, and injury to adjacent structures

Barrier

3

the tooth requiring treatment can be isolated from the remaining dentition, allowing it to better visualized

isolation

4

removal of the carious lesion

debridement

5

cutting the tooth to accommodate and hold the restorative material, and assuring that once restored, the tooth will withstand use

Preparation form

6

any impurities are removed and the tooth surfaces are cleaned

refine

7

is a “molding” device that surrounds the tooth to ensure the tooth wall maintains its original shape

matrix

8

maintaining the original tooth shape and contour, and ensuring that gingival space is not obstructed

embrasure

9

metal retaining device that is fitted and tightened around the tooth

Tofflemire matrix

10

round band with locking ends that are tightened and locked into place

AutoMatrix

11

cone-shaped steel rings with “wings” to retain its shape and hold

T-strip

12

metal strip acts to “replace” the tooth wall and is kept in position by the retainer

Sectional matrix and ivory retainer

13

strip is used for anterior restorations and is manually kept in place

Mylar strip

14

produces a lining against stress force, heat, and jolts

Insulation

15

encourages dentin growth

Palliation

16

temporary shield between treatment visits

Protection

17

usually used as a temporary measure to fasten the base material to the restorative material, between treatment visits

Luting

18

permanent attachment of restorative material to the prepared tooth

Cementation

19

thin layering of sub-material to the prepared tooth

Lamination

20

prevents leakage under restorations by sealing the cut edges of the prepared tooth

Varnish

21

liquid coating that produces a barrier against chemical irritation

Liner

22

acid solution that scratches/carves microspaces

Acid etchant

23

allows restorative agent to unite or “fuse” to the tooth surface

Bonding agent

24

barrier against heat and chemical irritation

Base

25

to retain metal posts and pins in deep tooth preparations

Cement

26

basic handling techniques (different products require different methods)

Manipulation

27

some products require a uniform blended mixture

Homogenous

28

preparing for an amalgam restoration by mixing the mercury and the metal alloy in a mechanical device.

Amalgamation or trituration

29

triturated mass is “kneaded” as a final step in amalgam mixing

Mulling

30

spreading the materials out, to be mixed in a larger area

Dissipate
