The term nanoleakage, is used to describe porosities located
within/under the hybrid layer in dimensions less than ___nm -
ANSWER --50nm.
- These are collagen-rich fibrous network created by
demineralization that should be penetrated by resin to
reinforce demineralized dentin structures.
What exactly are "water trees" or "water blisters"? - ANSWER -
When water is in
contact between the hybrid layer and dentin. It can create
voids and leakage
which will decrease bond longevity by hydrolysis of
methacrylate bonds.
What luting agents have the highest tensile strength and what
has the weakest?
- ANSWER -Resin is
highest
Hybird ionomer is
lower
,- GIC and Zinc Phospate are okay with
moisture
T/F: Impression material undergoes dimensional change on
setting. The major factor for contraction is cross-linking and
rearrangement of bonds within and between polymer chains. -
ANSWER --True
- Additional shrinkage can arise from the loss of volatile
components such as water in polysulfides and ethanol in
condensation silicones.
For impression materials, addition silicones and polyethers
experience ________ of by-products and are diemnsionally
stable. - ANSWER --no loss. -viscosity and temperature are
irrelevant to dimensional stability of these products.
Polyether impression material is _______ for dimensional
stability - ANSWER -
best.
hydrophillic and stiff
The role of Leucite in dental porcelian is for ________
flexural strength and
increased thermal contraction coefficient -
ANSWER -increased
Carbamide peroxide breaks down into hydrogen peroxide
and urea. This
,hydrogen peroxide then procduces _______ which then
breaks down the
discolored compounds on stained teeth. - ANSWER --
Free radicals
T/F: Bleached hydroxyapatite can lead to demineralization and
loss of calcium -
ANSWER -
True
What are usually the main components of root canal sealers
that are used for
radiopacity. - ANSWER -Zinc, barium and
bismuth salts
Nickel Titanium usually have ____ resiliency, _______
thermal memory and
_____ elastic modulus. - ANSWER -High,
High, Low
What are some ways infections can be transmitted Directly,
Indirectly or
Airborne? - ANSWER -Direct contact with blood,
saliva, and other secretions
Indirect contact with contaminated
instruments, equipment, and
surfaces Contact with airborne
contaminants
present in droplets, spatter, or aerosols
, Why should you never wash your gloves? - ANSWER -
avoid wicking
"penetration
of
liquids through undetected holes in
the gloves"
People with a latex allergy have Hypersensitivity type? -
ANSWER -Natural
rubber latex
(NRL):
Obtained from the tropical rubber tree, Hevea
brasiliensis
People with a high exposure to latex are at increased
risk for latex
hypersensitivity
(delayed
type
IV)
Risk appears to increase with greater
exposure
What are some dental materials that have latex? - ANSWER
-Prophy cup,
rubber dam, ortho elastics,
tourniquets,
and
gloves
