The only vasoconstrictor used in local anesthetics that is contraindicated with
concomitant MAO inhibitor therapy is:
A. phenylephrine.
B. norepinephrine.
C. epinephrine.
D. levonordetrin
Correct Answer: (A) phenylephrine.
Despite statements to the contrary in local anesthetic product information approved
by the FDA, local anesthetics containing epinephrine may be used without special
reservation in patients taking monoamine oxidase (MAO) inhibitors.
MAO inibitors
Antidepressant agents that work by blocking the action of a specific enzyme
Exogenous catecholamines are mostly degraded by the enzyme catechol-o-
methyltransferase; inhibition of MAO has little impact on their respective fates or
cardiovascular actions. Of the vasoconstrictors used with local anesthetics, only
phenylephrine is contraindicated with concomitant MAO therapy

All of the following statements about chemically activated (self cure) resins are
true except one. Which is the exception?
A. They have long term storage stability.
B. They can yellow with age.
C. The degree of cure is equal if mixed properly.
D. Marginal stress buildup is much higher than for photocured resins.
Correct Answer: (D) Marginal stress buildup is much higher than for
photocured resins.
Advantages of self-cure resins:
1) convenience and simplicity - no equipment needed, hazard free;
2) long-term storage stability;
3) manipulation of working/setting time by varying proportion; 4) degree of cure equal
throughout material if mixed properly; 5) marginal stress build-up during curing is
much lower than for photocured resins owning to relatively slower rates of cross-link
formation.
Disadvantages of self-cure resins:
1) mixing causes air entrapment, leading to porosity that weakens the material &
increases susceptibility to staining. This has been reduced by the use of mixing
syringes;
2) aromatic amine accelerators oxidize and turn yellow with time - i.e., color
instability;
3) difficult to mix evenly causing unequal degree of cure & consequently poor
mechanical properties.
There are extremely sensitive methods for detecting mercury in parts per
trillion. There is no data to show that the mercury released from dental
amalgam is harmful to the general population.
A. Both statements are TRUE.
B. Both statements are FALSE.
C. The first statement is TRUE; the second is FALSE.
D. The first statement is FALSE; the second is TRUE.
Correct Answer: (A) Both statements are TRUE. Humans are exposed to mercury
from a variety of sources in addition to dental amalgams. There are extremely
, Page 3 of 101
sensitive methods for detecting mercury in parts per trillion; these methods have
made it possible to analyze the sources of mercury exposure to humans. Numerous
studies have attempted to determine whether mercury exposure from dental
restorations or other sources contributes to any documentable health problem.
Several studies have estimated the number of amalgam surfaces needed to expose
an individual to mercury concentrations with a minimum observable effect (slightly
impaired psychomotor performance, detectable tremor and impaired nerve
conduction velocity). Estimates are that several hundred amalgam surfaces would be
necessary to achieve these levels. Other studies have measured renal function in
patients whom all of amalgam was removed at the same time (the worst possible
case). Despite markedly elevated blood plasma and urine levels of mercury, no renal
impairment was noted. There is simply no data to show that mercury released from
dental amalgam is harmful to the general population
A dental bonding system has all of the following essential functions except
one. Which is the exception?
A. Provides resistance to separation of a substrate from a restorative material.
B. Distributes stress along bonded interfaces.
C. Provides thermal insulation between materials.
D. Seals the interface
Correct Answer: (C) Provides thermal insulation between materials.
Bonding and adhesion comprise a complex set of physical, chemical & mechanical
mechanisms that allow the attachment & binding of one substance to another.
3 Essential Functions of a Dental Bonding System:
1) Provides resistance to separation of an adherent substrate (i.e., enamel, dentin,
metal composite, ceramic) from a restorative or cementing material;
2) Distributes stress along bonded interfaces; and
3) Seals the interface via adhesive bonding between dentin and/or enamel and the
bonded material, thus increasing resistance to micro-leakage and decreasing the risk
of postoperative sensitivity, marginal staining, and secondary caries.
The success of endosseous dental implants is based on the biocompatibility
of the implant surface and the ingrowth of new bone into the surface through
the process of osseointegration. There are many implant materials or implant
, Page 4 of 101
coatings that promote osseointegration.
A. Both statements are TRUE.
B. Both statements are FALSE.
Correct Answer: (C) The first statement is TRUE; the second is FALSE.
The general process of bio-integration involves adaptation of bone or other tissue to
the implanted materials without any intervening space along the tissue-material
interface. The success of endosseous dental implants is based on the
biocompatibility of the implant surface and the ingrowth of new bone at the tissue-
material interface through the process of osseointegration. Very few implant
materials or implant surface coatings promote osseointegration.
The most common implant materials include:
The most common implant materials include:
1) Commercially Pure Titanium (CPT)
2) Titanium-Aluminum-Vanadium Alloy
3) Tantalum
4) Some types of Ceramics Some materials, such as bio-glass ceramics, promote a
perfect osseointegratoin of the bone.
Currently, the etching time for most 37% phosphoric acid etching gels is
approximately _________ seconds.
A. 5 B. 10 C. 15 D. 20
Correct Answer: (C) 15 The etching time for most etching gels is approximately 15
seconds. The advantage of such short etching time is that they yield acceptable
bond strength while conserving enamel and reducing treatment time.
The opacity/translucency of a light-cured composite can affect curing times.
The particle size of a light-cured composite does not affect the curing time.
A. Both statements are TRUE.
B. Both statements are FALSE.
C. The first statement is TRUE; the second is FALSE.
D. The first statement is FALSE; the second is TRUE.
Correct Answer: (C) The first statement is TRUE; the second is FALSE.
All optical modifiers affect light transmission through a composite. Darker shades
