What is the “gold standard” for pulp capping?
Dycal (CaOH)
The most important factor for DIRECT pulp cap success is:
control of hemostasis
A tooth with irreversible pulpitis will demonstrate:

T/F: Pulp capping should be avoided if placing a crown/bridge on that tooth. After a direct pulp cap, the pulp typically “heals” within 2-6 days.
First statement true; second statement false (4-6 weeks is healing phase)

A patient comes in complaining of a toothache. When asked to describe the character of pain, the patient states that it generally hurts on the upper teeth but cannot isolate it to a single tooth. The patient also says tilting his head makes the pain worse. What is the most likely cause of pain?
maxillary sinus infection
- upper teeth pain but can’t isolate
- pain worsens with tilting head
After gingivectomy, complete connective tissue repair occurs ____ post-op.
6 weeks
T/F: A midline deviation under 4mm is typically unnoticeable by others. A midline deviation that is canted in one direction is more noticeable.
both statements true
Which of the following statements describes organic methyl mercury?
i) found in seafood
ii) least toxic form of mercury
iii) water soluble
iv) absorbed by the lungs
v) not found in amalgam
1- found in seafood
5- not found in amalgam
In dental practices, mercury vapor is typically released when:
- amalgam is in its liquid form
- amalgam restorations are removed
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
masticating on an amalgam restoration releases an inconsiderable amount of mercury
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.
S1- false (urine)
S2- true
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
all true
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
ALL true
The purpose of etching in composite bonding is to:
- increase surface area of enamel
- remove the smear layer
- allow penetration of resin into the dentin
- increase surface energy
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
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
When is the open-sandwich technique indicated?
Large class II lesion extending BEYOND the CEJ
Which maxillary tooth typically has the highest shade value, in an esthetic smile?
central incisors
Glass ionomer cements are contraindicated for use in/as:
- non-cervical carious lesions
- sedative fillings
- large class II lesion
- base for deep class I
- none of the above
Large class II lesion (unsure on this)
The purpose of silane in composites is to:
transfer stress between matrix and filler
Transfers stress between matrix and filler:
silane in composites
Chlorhexidine is used:
- in universal bonding agents
- to increase composite bond strength
- to prevent collagen breakdown in dentin
(all of the above)
T/F: Commercialism the driving force for dentists in developing treatments. If treatment is purely cosmetic, the patient does NOT need to be told it is unnecessary.
S1- False
S2- False
F28, for a camera would indicate:
