Preclinical/Sim Lab (complete)

Question 1

What is a bur

Answer 1

burs are milled from steel or carbide stock with cutting blades of all shapes and sizes.

Question 2

What is the most popular stock used for burs and why

Answer 2

Tungsten carbide, and that is because the burs are longer lasting, sharper, and maintain a sharp cutting edge longer than steel

Question 3

What are burs used for

Answer 3

enamel and dentin cutting as well as finishing and polishing tooth and restorative materials

Question 4

What are diamonds

Answer 4

diamonds are made by bonding diamond particles to a milled shaft.

Question 5

Do diamonds come in many shapes and sizes

Answer 5

yes

Question 6

What are diamonds used for

Answer 6

every type of restorative procedure from cutting and reducing tooth, to fine polishing of restorations and porcelain.

Question 7

How should the valo light be held when curing composite?

Answer 7

have the light very close to the tooth, and parallel to the area we are curing

Question 8

What does it mean that the valo light beam is collimated

Answer 8

that the light exits the valo in a column, making it more concentrated. As opposed to coming out and spreading out like a fan.

Question 9

Why does the valo light use LED lights of different frequencies

Answer 9

1. to make sure the valo light will cure all different types of composite. Some composites require different frequencies of lights than others.
2. It also doesn’t lose power over time, so you know your getting the composite cured

Question 10

What is the dispenser gun used for

Answer 10

dispensing composites and other materials

Question 11

Why is it important the way that the VALO light is angled the way it is

Answer 11

Because we can get it positioned better, and thus better cure the composite. The patient won’t need to open their mouth so wide to get it in

Question 12

What are the power levers of the VALO

Answer 12

Standard - 1000 mW/cm^2

HIgh Power - 1400 mW/cm^2

Plasma Emulation - 3200 mW/cm^2

Question 13

What is the Wavelength of the VALO light

Answer 13

395 nm - 480 nm

Question 14

How many LED lights are in the valo light

Answer 14

4

Question 15

What is the benefit of collumation

Answer 15

All of the power comes straight out of the light, better curing whatever the light hits

Question 16

What is a downside of collumation

Answer 16

The light doesn’t spread out so you need to be more accurate with your placement. or on large restorations you may have to cure more than once

Question 17

What are the two most common photoinitiators the VALO light will cure

Answer 17

Camphorquinone

Proprietary

Question 18

How does the VALO indicate which power lever you are on

Answer 18

Standard - the light will be solid green

High Power - the light will be solid orange

Plasma Emulation - the light will be flashing orange

Question 19

What are the different timing intervals for each power level

Answer 19

Standard Power - 5, 10, 15, 20 Seconds

High Power - 1, 2, 3, 4, seconds

Plasma Emulation - 3 seconds

Question 20

What is a hemostat and what is it used for

Answer 20

the curved locking clamping scissor things

they are used to pick up, place, remove things.

Question 21

Policy Questions Are Asked on the test

Answer 21

yes

Question 22

What is the curing time PER LAYER for each power level

Answer 22

Standard - 1 X 10 seconds

High Power - 1 X 4 seconds

Plasma Emulation - 1 X 3 seconds

Question 23

What is the FINAL cure time for each of the power levels

Answer 23

Standard - 1 x 20 Seconds

High Power - 3 x 4 seconds

Plasma Emulation - 2 x 3 seconds

Question 24

What are the benefits of properly using the VALO light

Answer 24

It produces a harder/stronger bond

relieves composite stress

Question 25

what are iris scissors and what are they used for

Answer 25

The small scissors

they are used for cutting light materials,

no metal, paper, or heavy plastics

Question 26

what are the bigger scissors called and what are they used for

What is the acorn burnisher and what is it used for

Answer 27

a burnisher used for shaping and carving amalgum and composite

Question 28

What are the ball burnishers and what are they used for

Answer 28

balls on the ends

used for burnishing matrix bands and amalgum, shaping composite

Question 29

What are condensors and what are they used for

Answer 29

the cylinders with flat ends

they are used for packing amalgum into cavity preps, sometimes used with composites

Question 30

What is the cleoid discoid and what is it used for

Answer 30

the spade shape on one end, the cirlce on the other

carving amalgum and wax

Question 31

what is the half hollenbeck and what is it used for
