CHOICE
1. Which descriptive term is described as a segment that is part of the whole?
a. Bulla
b. Vesicle
c. Lobule
d. Pustule
ANS: C
A lobule is described as a segment or lobe that is part of a whole. A bulla is a
large, elevated lesion that contains serous fluid and may look like a blister. A
vesicle is a small, elevated lesion that contains serous fluid. 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
Sessile describes the base of a lesion that is flat and broad. An ulcer is a break
in the surface epithelium. A stemlike lesion referred 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
ANS: D
The compound odontoma is initially identified radiographically as a radiopaque
area in which tooth 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
wiseprof
, 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.

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
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
