MULTIPLE CHOICE
1. What term describes a segment that constitutes part of a whole?
A. Bulla
B. Vesicle
C. Lobule
D. Pustule
RIGHT CHOICE✔✔ C
ELABORATION> A lobule is a portion or lobe that forms part of a larger whole. A bulla is
a sizable, raised lesion filled with serous fluid, resembling a blister. A vesicle is a small,
raised lesion also containing serous fluid. Pustules are defined as raised areas that contain
pus and are circumscribed in appearance.
2. A lesion with a sessile base is described as
A. an ulcer.
B. stemlike.
C. pedunculated.
D. flat and broad.
RIGHT CHOICE✔✔ D
ELABORATION> Sessile describes the base of a lesion that is flat and broad. An ulcer is a
break in the surface epithelium. A stemlike lesion is referred to as pedunculated. A
pedunculated lesion is stemlike or stalk-based (similar to a mushroom).
3. Which condition is not diagnosed through clinical appearance?
A. Mandibular tori
B. Fordyce granules
C. Black hairy tongue
D. Compound odontoma
RIGHT CHOICE✔✔ D
ELABORATION> The compound odontoma is initially identified radiographically as a
radiopaque area in whichtooth structure can be identified. No clinical component exists.
Mandibular tori are identified clinically as areas of exostosis on the lingual aspects of
mandibular premolars. Fordyce granules are yellow clusters of ectopic sebaceous glands
diagnosed through clinical appearance. 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.

4. Another name for geographic tongue is
, A. median rhomboid glossitis.
B. benign migratory glossitis.
C. fissured tongue.
D. black hairy tongue.
RIGHT CHOICE✔✔ B
ELABORATION> 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 in5% 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.

5. 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 appearance. Which
condition is suspected?
A. Palatal cyst
B. Torus palatinus
C. Mixed tumor
D. Ranula
RIGHT CHOICE✔✔ B
ELABORATION> 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 orpleomorphic 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.

, 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 termed
A. linea alba.
B. leukoedema.
C. leukoplakia.
D. white sponge nevus.
RIGHT CHOICE✔✔ B
ELABORATION> 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 hospital patients who have a clenching or
grinding habit. Leukoplakia is a clinical term for a white lesion, the cause of which is
unknown. Whitesponge 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.

7. Which condition most likely responds to therapeutic diagnosis?
A. Angular cheilitis
B. Amelogenesis imperfecta
C. Paget disease
D. Stafne bone cyst
RIGHT CHOICE✔✔ A
ELABORATION> Angular cheilitis most commonly responds to antifungal therapy once
nutritional deficiencies have been ruled out. Amelogenesis imperfecta is a genetic condition
associated with abnormaldevelopment of the enamel. Paget disease is a chronic metabolic
bone disease. A highly elevated serum alkaline phospNhUatRaS

the diagnosis. A Stafne
bone cyst is determined through surgical diagnosis in which entrapped salivary gland tissue is
identified.

8. The gingival enlargement in this hospital patient was caused by a calcium channel
blocker. Whichmedication is the likely cause?
A. Dilantin
B. Nifedipine
C. Quinidine
D. Clozapine
