Q

How should the valo light be held when curing composite?

A

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

Q

What does it mean that the valo light beam is collimated

A

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

Q

Why does the valo light use LED lights of different frequencies

A
  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

Q

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

A

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

Q

What is the benefit of collumation

A

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

16
Q

What is a downside of collumation

A

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

17
Q

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

A

Camphorquinone

Proprietary

18
Q

How does the VALO indicate which power lever you are on

A

Standard - the light will be solid green

High Power - the light will be solid orange

Plasma Emulation - the light will be flashing orange

19
Q

What are the different timing intervals for each power level

A

Standard Power - 5, 10, 15, 20 Seconds

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

Plasma Emulation - 3 seconds

20
Q

What is a hemostat and what is it used for

A

the curved locking clamping scissor things

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

21
Q

Policy Questions Are Asked on the test

22
Q

What is the curing time PER LAYER for each power level

A

Standard - 1 X 10 seconds

High Power - 1 X 4 seconds

Plasma Emulation - 1 X 3 seconds

23
Q

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

A

Standard - 1 x 20 Seconds

High Power - 3 x 4 seconds

Plasma Emulation - 2 x 3 seconds

24
Q

What are the benefits of properly using the VALO light

A

It produces a harder/stronger bond

relieves composite stress

25
what are iris scissors and what are they used for
The small scissors they are used for cutting light materials, no metal, paper, or heavy plastics
26
what are the bigger scissors called and what are they used for
curved crown or collar scissors they are used for cutting heavy materials paper, plastics, and metal
27
What is the acorn burnisher and what is it used for
a burnisher used for shaping and carving amalgum and composite
28
What are the ball burnishers and what are they used for
balls on the ends used for burnishing matrix bands and amalgum, shaping composite
29
What are condensors and what are they used for
the cylinders with flat ends they are used for packing amalgum into cavity preps, sometimes used with composites
30
What is the cleoid discoid and what is it used for
the spade shape on one end, the cirlce on the other carving amalgum and wax
31
what is the half hollenbeck and what is it used for
a long skinny spade shape on both ends used forcarving amalgum and wax, as well as shaping composite
32
Cleoid discoid vs. half hollenbeck
33
what are the IPC carvers and what are they used for
the flat skinny ended instruments they are used for placing and shaping composite
