Question 2

Tooth-colored materials composed of an organic resin matrix, inorganic filler particles, a coupling agent, and coloring pigments

Answer 2

Composite Resins

Question 3

Thick liquids made up of two or more types of organic molecules (polymers) that form a matrix around filler particles

Answer 3

Organic Resin Matrix

Question 4

Fine particles of quartz, silica, or glass that give strength and wear resistance to a material

Answer 4

Inorganic Filler Particles

Question 5

A chemical that helps to bind the filler particles to the organic matrix

Answer 5

Silane Coupling Agent

Question 6

Coloring agents that give composites their color

Answer 6

Pigments

Question 7

High molecular weight molecules with double carbon bonds that link to form polymers

Answer 7

Monomers

Question 8

Composites that polymerize by a chemical reaction when two filled resin pastes are mixed together

Answer 8

Self-cured composites

Question 9

Single-paste composites that polymerize when a photosensitive chemical is activated by light in the blue wave range

Answer 9

Light-cured composites

Question 10

Composites that contain components of light activated and chemically activated materials. When the two parts are mixed together, it polymerizes by a chemical reaction that can be accelerated by blue light activation

Answer 10

Dual-cured composites

Question 11

An early generation of composites that contained filler particles ranging from 10-100 microns

Answer 11

Macrofilled composites

Question 12

Composites that contain very small filler particles averaging 0.04 microns in diameter

Answer 12

Microfilled composites

Question 13

Composites that contain both fine fill (2 to 4 microns) and microfill (0.04 to 0.2 micron) particles to obtain the strength of a macrofill and the polishability of a microfill

Answer 13

Hybrid composites

Question 14

Hybrid composites that contain fillers that are smaller fine-particle (0.04 to 1 micron) and microsized fillers

Answer 14

Microhybrids

Question 15

Microhybrids to which nanosized fillers have been added

Answer 15

Nanohybrids

Question 16

Composites that have physical and mechanical properties such as strength and polishability that allow them to be used in both the anterior and posterior parts of the mouth

Answer 16

Universal composites

Question 17

Comopsites that contain all nanosized fillers to enhance physical properties

Answer 17

Nanocomposites

Question 18

Light-cured, low-viscosity composite resins

Answer 18

Flowable composites

Question 19

Composites with greater depth of cure that permit placement in large increments up to 4 mm thick instead of the standard 2mm; their use speeds up the filling process

Answer 19

Bulk-fill composites

Question 20

A measure of the stiffness of a material; the higher the elastic modulus the stiffer that material

Answer 20

Elastic modulus

Question 21

A technique for composites that places and cures small increments individually to reduce the overall polymerization shrinkage and shrinkage stress in the restoration

Answer 21

Incremental placement

Question 22

Tooth-colored materials that are sued to construct restorations outside of the mouth in the dental laboratory or at chairside on replicas of the prepared teeth. They are later cemented to the teeth.

Answer 22

Indirect-Placement Esthetic Materials

Question 23

Self-cured, tooth-colored, fluoride-releasing restorative materials that bond to tooth structure without additional bonding agent.

Answer 23

Glass Ionomer Cements (GICs)

Question 24

A glass ionomer to which resin has been added to improve its physical properties

Answer 24

Hybrid (or-resin modified) glass ionomer

Question 25

Glass ionomers that contain nanosized filler particles to enhance their physical properties

Answer 25

Nano-ionomers

Question 26

Composite resin that has polyacid, fluoride-releasing groups added

Answer 26

Compomer
