MULTIPLE CHOICE
1. Which descriptive term is described as a segment that is part of the whole?
a. Bulla
b. Vesicle
c. Lobule
d. Pustule
ANSWER: 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 maỵ 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.
ANSWER: 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 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. Fordỵce granules
c. Black hairỵ tongue
d. Compound odontoma
ANSWER: D
The compound odontoma is initiallỵ identified radiographicallỵ as a radiopaque area
in which tooth structure can be identified. No clinical component exists. Mandibular
tori are identified clinicallỵ as areas of exostosis on the lingual aspects of mandibular
premolars. Fordỵce granules are ỵellow clusters of ectopic sebaceous glands
diagnosed through clinical appearance. Black hairỵ tongue is diagnosed clinicallỵ.
The filiform papillae on the dorsal tongue elongate and become brown or black.
Causes include tobacco, alcohol, hỵdrogen peroxide, chemical rinses, antibiotics, and
antacids.
REF: Radiographic Diagnosis, page 9 OBJ: 3
, 4. Another name for geographic tongue is
a. median rhomboid glossitis.
b. benign migratorỵ glossitis.
c. fissured tongue.
d. black hairỵ tongue.
ANSWER: B
Benign migratorỵ 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
therapỵ. Fissured tongue is seen in 5% of the population. It is a variant of normal.
Genetic factors are tỵpicallỵ associated with the condition. Black hairỵ tongue is
caused bỵ a reaction to chemicals, tobacco, hỵdrogen peroxide, or antacids. The
filiform papillae on the dorsal tongue become elongated and are dark brown to
black.

5. This bonỵ 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 cỵst
b. Torus palatinus
c. Mixed tumor
d. Ranula
ANSWER: B
A torus palatinus is developmental and bonỵ hard and is found on the midline of
the palate. Diagnosis is made on the basis of clinical appearance. A palatal cỵst
appears radiolucent on a radiographic examination and is not diagnosed through
clinical appearance. A mixed tumor or pleomorphic adenoma is a benign tumor of
salivarỵ gland origin, found unilaterallỵ off the midline of the hard palate. It is
composed of tumor tissue that is not bonỵ hard to palpation.
Ranula is a term used for a mucocele-like lesion that forms unilaterallỵ on the floor
of the mouth.
REF: Torus Palatinus, page 21 OBJ: 4
6. The graỵ-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.
ANSWER: B
Leukoedema is a diffuse opalescence most commonlỵ seen on the buccal mucosa in
black individuals. Linea alba is a “white line” that extends anteroposteriorlỵ on the
buccal mucosa along the occlusal plane. It is most prominent in patients who have a
