Preclinical/Sim Lab (complete) Flashcards
What is a bur
burs are milled from steel or carbide stock with cutting blades of all shapes and sizes.
What is the most popular stock used for burs and why
Tungsten carbide, and that is because the burs are longer lasting, sharper, and maintain a sharp cutting edge longer than steel
What are burs used for
enamel and dentin cutting as well as finishing and polishing tooth and restorative materials
What are diamonds
diamonds are made by bonding diamond particles to a milled shaft.
Do diamonds come in many shapes and sizes
yes
What are diamonds used for
every type of restorative procedure from cutting and reducing tooth, to fine polishing of restorations and porcelain.
How should the valo light be held when curing composite?
have the light very close to the tooth, and parallel to the area we are curing
What does it mean that the valo light beam is collimated
that the light exits the valo in a column, making it more concentrated. As opposed to coming out and spreading out like a fan.
Why does the valo light use LED lights of different frequencies
- to make sure the valo light will cure all different types of composite. Some composites require different frequencies of lights than others.
- It also doesn’t lose power over time, so you know your getting the composite cured
What is the dispenser gun used for
dispensing composites and other materials
Why is it important the way that the VALO light is angled the way it is
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
What are the power levers of the VALO
Standard - 1000 mW/cm^2
HIgh Power - 1400 mW/cm^2
Plasma Emulation - 3200 mW/cm^2
What is the Wavelength of the VALO light
395 nm - 480 nm
How many LED lights are in the valo light
4
What is the benefit of collumation
All of the power comes straight out of the light, better curing whatever the light hits
What is a downside of collumation
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
What are the two most common photoinitiators the VALO light will cure
Camphorquinone
Proprietary
How does the VALO indicate which power lever you are on
Standard - the light will be solid green
High Power - the light will be solid orange
Plasma Emulation - the light will be flashing orange
What are the different timing intervals for each power level
Standard Power - 5, 10, 15, 20 Seconds
High Power - 1, 2, 3, 4, seconds
Plasma Emulation - 3 seconds
What is a hemostat and what is it used for
the curved locking clamping scissor things
they are used to pick up, place, remove things.
Policy Questions Are Asked on the test
yes
What is the curing time PER LAYER for each power level
Standard - 1 X 10 seconds
High Power - 1 X 4 seconds
Plasma Emulation - 1 X 3 seconds
What is the FINAL cure time for each of the power levels
Standard - 1 x 20 Seconds
High Power - 3 x 4 seconds
Plasma Emulation - 2 x 3 seconds
What are the benefits of properly using the VALO light
It produces a harder/stronger bond
relieves composite stress
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
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
What is the acorn burnisher and what is it used for
a burnisher used for shaping and carving amalgum and composite
What are the ball burnishers and what are they used for
balls on the ends
used for burnishing matrix bands and amalgum, shaping composite
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
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
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
Cleoid discoid vs. half hollenbeck
what are the IPC carvers and what are they used for
the flat skinny ended instruments
they are used for placing and shaping composite
what is the explorer/probe and what is it used for
it has the skinny hook on one end and the straight skinny measuing probe
it is a diagnostic instrument
caries detection, adequacy of restoration, enamel defects, measure periodontal pockets, 1mm increments
what is the amalgum carrier and what is it used for
picks up amalgum and places into cavity prep
What is our access to the sim lab
- during course instruction periods
- 7am - 11 pm Monday - Thursday
- 6 am - 5 pm Friday
- 10am - 6 pm saturdays
- NOT DURING OTHER SCHEDULED CLASSES
- NOT WHILE OTHER CLASSES ARE IN THE SIM LAB
Why do we need to wear scrubs
to be professional
can you take the practical exams without having finished your daily projects
nope
