Question 1: Which cardiovascular disease is associated with
periodontal disease, placing an emphasis on improving oral health
in an attempt to reduce the risk of disease?
A. Cerebrovascular disease
B. Hypertension
C. Congestive heart failure
D. Coronary artery atherosclerosis
Answer:
d - Coronary artery atherosclerosis is associated with periodontal disease.
Decreasing periodontal disease symptoms through preventative and
maintenance care will reduce the patient's risk factors.
Question 2: Local anesthetics containing vasoconstrictors should
not be administered to asthma patients. It also should not be used
for patients that suffer from emphysema.
A. Both statements are true
B. Both statements are false
C. The first statement is true, the second statement is false
D. The first statement is false, the second statement is true
Answer:
c - The first statement is true, the second statement is false. Local anesthetics
containing vasoconstrictors should not be given to asthma patients because it
may cause reduced oxygen flow in the body, but they may be administered to
patients with emphysema.
,Question 3: What type of seizure exhibits symptoms of jerking
motions and no loss of consciousness?
A. Status epilepticus
B. Petit mal
C. Grand mal
D. None of the above
Answer:
b - Petit mal seizures are simple, with jerking motions and no loss of
consciousness. The patient is aware of their surroundings and is able to
recount the episode without loss of memory.
Question 4: What disease exhibits itself in a classic "butterfly"
pattern rash over the patient's face?
A. Phemphigus vulgaris
B. Hodgkin's lymphoma
C. Scleroderma
D. Lupus
Answer:
d - Lupus is a chronic disease that displays a "butterfly" pattern over the
patient's face.
Question 5: Wedge-shaped lesions along the cervical margin of the
teeth are referred to as .
A. Erosion
B. Abrasion
C. Abfraction
D. Attrition
Answer:
, c - Abfractions are the wedge-shaped lesion along the cervical margin of the
teeth, usually due to fatigue or flexing of the tooth. The excess flexing causes
enamel to chip off of the tooth in this area, exposing the dentin.
Question 6: A condition of the oral tissues due to hormonal
changes during pregnancy is called ___________.
A. Pyogenic granuloma
B. Sialolith
C. Gingival hyperplasia
D. Inflammatory papillary hyperplasia
Answer:
a - Pyogenic granulomas is a reactive tissue hyperplasia related to hormonal
changes, usually associated with pregnancy. This condition may also be called
"pregnancy tumors."
Question 7: A discoloration of the oral mucosa that may have a
radiopaque appearance.
A. Traumatic neuroma
B. Amalgam tattoo
C. Necrotizing sialometaplasia
D. Melanoma
Answer:
b - Amalgam tattoos are bluish discolorations of the oral mucosa due to
leaking of particles from an amalgam filling directly into the mucosa.
Therefore, they may appear radiopaque on a radiograph.
Question 8: Which cyst exhibits bluish swelling around a newly
erupting crown, most common with the eruption of primary teeth?
A. Odontogenic keratocyst
, B. Dentigerous cyst
C. Nonodontogenic cysts
D. Eruption cyst
Answer:
d - Eruption cysts usually involve primary tooth eruption and exhibit bluish
tissue with swelling around the erupting tooth, hence the term "eruption cyst."
Question 9: Supernumerary teeth usually exhibit microdontia. They
are most commonly found in the maxilla.
A. Both statements are true
B. Both statements are false
C. The first statement is true, the second statement is false
D. The first statement is false, the second statement is true
Answer:
a - Both statements are true. Supernumerary teeth typically exhibit microdontia
(small in size) and are in the maxilla, typically distal to the 3rd molars or
between the upper central incisors.
Question 10: Which of the following is an exophytic area of enamel
on the root surface?
A. Dens in dente
B. Enamel pearl
C. Enamel hypoplasia
D. Gemination
Answer:
b - Enamel pearls are projections of an exophytic area of enamel on the
surface of a root. The area appears as a small round "pearl" of enamel on the
surface where enamel isn't normally found.
