MULTIPLE
CHOICE
1. Another name for geographic tongue is
a. median rhomboid glossitis.
b. benign migratory glossitis.
c. fissured tongue.
d. black hairy tongue.
ANS: B
Benign migratory glossitis is another name for geographic
tongue. Research suggests that median rhomboid glossitis
is associated with a chronic fungal infection from Candida
albicans. Sometimes the condition resolves with antifungal
therapy. Fissured tongue is seen in 5% of the population. It is
a variant of normal. Genetic factors are typically associated
with the condition. Black hairy tongue is caused by a
reaction to chemicals, tobacco, hydrogen peroxide, or
antacids. The filiform papillae on the dorsal tongue become
elongated and are dark brown to black.

2. This bony hard structure in the midline of the hard palate is
genetic in origin and inherited in an autosomal dominant
manner. The diagnosis is made through clinical
,Page 2 of 582
appearance. Which condition is suspected?
a. Palatal cyst
b. Torus palatinus
c. Mixed tumor
d. Ranula
ANS: B
A torus palatinus is developmental and bony hard and is
found on the midline of the palate. Diagnosis is made on the
basis of clinical appearance. A palatal cyst appears
radiolucent on a radiographic examination and is not
diagnosed through clinical appearance. A mixed tumor or
pleomorphic adenoma is a benign tumor of salivary gland
origin, found unilaterally off the midline of the hard palate. It
is composed of tumor tissue that is not bony hard to
palpation.
Ranula is a term used for a mucocele-like lesion that forms
unilaterally on the floor of the mouth.
REF: Torus Palatinus, page 21 OBJ: 4
3. The gray-white opalescent film seen on the buccal mucosa
of 85% of black adults is a variant of normal that requires
no treatment and is termed
a. linea alba.
b. leukoedema.
c. leukoplakia.
d. white sponge nevus.
ANS: B
Leukoedema is a diffuse opalescence most commonly seen
on the buccal mucosa in black
individuals. Linea alba is a “white line” that extends
anteroposteriorly on the buccal mucosa along the occlusal
plane. It is most prominent in patients who have a clenching
or grinding habit. Leukoplakia is a clinical term for a white
lesion, the cause of which is unknown. White sponge nevus
is a genetic (autosomal dominant) trait. Clinically, it is
characterized by a soft white, folded (or corrugated) oral
mucosa. A thick layer of keratin produces the whitening.

4. Which condition most likely responds to therapeutic diagnosis?
a. Angular cheilitis
b. Amelogenesis imperfecta
c. Paget disease
d. Stafne bone cyst
ANS: A
Angular cheilitis most commonly responds to antifungal
therapy once nutritional deficiencies have been ruled out.
Amelogenesis imperfecta is a genetic condition associated
with abnormal development of the enamel. Paget disease is
a chronic metabolic bone disease. A highly elevated serum
alkaline phosphatase level contributes significantly to the
diagnosis. A Stafne bone cyst is determined through surgical
diagnosis in which entrapped salivary gland tissue is
identified.
REF: Therapeutic Diagnosis, page 18 OBJ: 3
5. The gingival enlargement in this patient was caused by
a calcium channel blocker. Which medication is the
likely cause?
a. Dilantin
b. Nifedipine
c. Quinidine
d. Clozapine
ANS: B
Nifedipine is a calcium channel blocker. Dilantin is an
anticonvulsant used to prevent or control seizures. Quinidine
is an antiarrhythmic agent used to treat cardiac
arrhythmias.
Clozapine is an antipsychotic used in the management of
psychotic symptoms in schizophrenia.

6. Radiographic features, including cotton-wool
radiopacities and hypercementosis, are
especially helpful in the diagnosis of
a. Paget disease.
b. dentinogenesis imperfecta.
c. anemia.
, Page 4 of 582
d.diabetes.
ANS: A
Paget disease is a chronic metabolic bone disease.
Radiographically, cotton-wool radiopacities and
hypercementosis are characteristic features. Dentinogenesis
imperfecta is a genetic condition involving a defect in the
development of dentin. Anemia, a decrease in red blood
cells, requires blood tests to determine the etiologic factors.
Diabetes is a chronic disorder of carbohydrate metabolism
characterized by abnormally high blood glucose levels.
REF: Laboratory Diagnosis, Fig. 1.40, pages 16, 18 OBJ: 3
7. In internal resorption, the radiolucency seen on
radiographic examination is usually
a. well circumscribed.
b. diffuse.
c. multilocular.
d. unilocular.
ANS: B
Diffuse borders are ill defined, making it impossible to
detect the exact parameters of the lesion. Therefore
treatment is more difficult. Well circumscribed describes
borders that are specifically defined. Exact margins of the
lesion are identified. Multilocular has also been described as
resembling “soap bubbles”; lobes seem to fuse together to
make up the lesion.
This term has been used to describe the odontogenic
keratocyst. Unilocular means having one compartment or
unit that is well defined. This term is often used to describe
the radicular cyst.
REF: Vocabulary, Radiographic Terms Used to
Describe Lesions in Bone, page 5 OBJ: 1
8. Which condition is diagnosed through clinical appearance?
a. Fordyce granules
b. Unerupted mesiodens
c. Periapical cemento-osseous dysplasia
d. Traumatic bone cyst
ANS: A
