MULTIPLE CHOICE
1. Which of the following would be described as a segment that is part of the whole?
A. Bulla
B. Vesicle
C. Lobule
D. Pustule
ANS: C
Feedback
A A bulla is a large, elevated lesion that contains serous fluid and may look like a
blister.
B A vesicle is a small, elevated lesion that contains serous fluid.
C Correct! A lobule is described as a segment or lobe that is part of a whole.
D Pustules are circumscribed elevations containing pus.
2. A lesion with a sessile base is described as:
A. an ulcer.
B. stemlike.
C. pedunculated.
D. flat and broad.
ANS: D
Feedback
A An ulcer is a break in the surface epithelium.
B A stemlike lesion is referred to as pedunculated.
C A pedunculated lesion is stemlike or stalk-based (similar to a mushroom).
D Correct! Sessile describes the base of a lesion that is flat and broad.
3. Which one of the following is not diagnosed through clinical appearance?
A. Mandibular tori
B. Fordyce granules
C. Black hairy tongue
D. Compound odontoma
ANS: D
Feedback
A Mandibular tori are identified clinically as areas of exostosis on the lingual
, aspects of mandibular premolars.
B Fordyce granules are yellow clusters of ectopic sebaceous glands that are
diagnosed through clinical appearance.
C Black hairy tongue is diagnosed clinically. The filiform papillae on the dorsal
tongue elongate and become brown or black. Causes include tobacco, alcohol,
hydrogen peroxide, chemical rinses, antibiotics, and antacids.
D Correct! The compound odontoma is initially identified radiographically as a
radiopaque area in which tooth structure can be identified. There is no clinical
component.
REF: Radiographic Diagnosis, page 9 OBJ: 3
4. Another name for geographic tongue is:
A. median rhomboid glossitis.
B. benign migratory glossitis.
C. fissured tongue.
D. black hairy tongue.
ANS: B
Feedback
A Research suggests that median rhomboid glossitis is associated with a chronic
fungal infection from Candida albicans. Sometimes the condition resolves with
antifungal therapy.
B Correct! Benign migratory glossitis is another name for geographic tongue.
C Fissured tongue is seen in 5% of the population. It is a variant of normal.
Genetic factors are probably associated with the condition.
D 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.

5. This bony hard radiopaque 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
appearance.
You suspect a:
A.palatal cyst.
B.torus palatinus.
C.mixed tumor.
D.ranula.
, ANS: B
Feedback
A A palatal cyst is radiolucent and not diagnosed through clinical appearance.
B Correct! 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.
C 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.
D Ranula is a term used for a mucocele-like lesion that forms unilaterally on the
floor of the mouth.
REF: Torus Palatinus, page 32 OBJ: 4
6. 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 called:
A. linea alba.
B. leukoedema.
C. leukoplakia.
D. white sponge nevus.
ANS: B
Feedback
A 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.
B Correct! Leukoedema is a diffuse opalescence most commonly seen on the
buccal mucosa in black individuals.
C Leukoplakia is a clinical term for a white lesion, the cause of which is unknown.
D 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.
REF: Leukoedema, page 24 OBJ: 8
7. Which one of the following conditions would most likely respond to therapeutic diagnosis?
A. Angular cheilitis
B. Amelogenesis imperfecta
C. Paget disease
D. Stafne bone cyst
ANS: A
Feedback
A Correct! Angular cheilitis most commonly responds to antifungal therapy once
nutritional deficiencies have been ruled out.
B Amelogenesis imperfecta is a genetic condition associated with abnormal
development of the enamel.
C Paget disease is a chronic metabolic bone disease. A highly elevated serum
