ii) least toxic form of mercury
iii) water soluble
iv) absorbed by the lungs
v) not found in amalgam

A

1- found in seafood
5- not found in amalgam

23
Q

In dental practices, mercury vapor is typically released when:

A
  1. amalgam is in its liquid form
  2. amalgam restorations are removed
24
Q

Which of the following about amalgam exposure is true?

  • amalgam restorations cause a 50% reduction in kidney function
  • mercury is able to migrate through roots and accumulate in the bone
  • masticating on an amalgam restoration relates an INCONSIDERABLE amount of mercury
  • people with amalgam restorations tend to have a HIGH mercury content in their urine
A

masticating on an amalgam restoration releases an inconsiderable amount of mercury

25
Q

T/F: Measuring mercury in the blood is the most accurate representation of exposure. Less than 1% of mercury of environmental mercury release comes from dental offices.

A

S1- false (urine)
S2- true

26
Q

Amalgam separators:

  • are now mandated by the EPA in dental offices
  • are more efficient at collecting amalgam waste
  • collect amalgam prior to central vacuum pump
  • all true
A

all true

27
Q

What is NOT UMKC clinic protocol when it comes to intraoral photography?

  • only write the patients chart on the provided envelope
  • never view the photographs on any device other than the camera
  • hand the camera and its bag without gloves
  • do not throw away flash batteries if they are dead
A

ALL true

28
Q

The purpose of etching in composite bonding is to:

A
  1. increase surface area of enamel
  2. remove the smear layer
  3. allow penetration of resin into the dentin
  4. increase surface energy
29
Q

What is FALSE about glass ionomer materials?

  • glass ionomer should NEVER be etched with phosphoric acid
  • The FAS glass component of GI releases fluoride
  • The shade selection for GI is more limited to resin composite
  • GI has a stronger bond to the tooth than resin composite
A

GI has a stronger bond to the tooth than resin- this is false but it does prevent shrinkage and is able to penetrate the dentin

30
Q

When is the open-sandwich technique indicated?

A

Large class II lesion extending BEYOND the CEJ

31
Q

Which maxillary tooth typically has the highest shade value, in an esthetic smile?

  • sedative fillings
  • large class II lesion
  • base for deep class I
  • none of the above
A

Large class II lesion (unsure on this)

33
Q

The purpose of silane in composites is to:

transfer stress between matrix and filler

34
Q

Transfers stress between matrix and filler:

A

silane in composites

35
Q

Chlorhexidine is used:

A
  1. in universal bonding agents
  2. to increase composite bond strength
  3. to prevent collagen breakdown in dentin

(all of the above)
