,Chapter 01: Introduction to Preliminary Diagnosis of Oral Lesions
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 may look like a blister. A vesicle is a small, elevated lesion that contains serous fluid.
Pustules are circumscribed elevations containing pus.
REF: Vocabulary, Clinical of Soft Tissue Lesions, page 1 OBJ: 1
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).
REF: Vocabulary, Clinical Appearance of Soft Tissue Lesions, page 1 OBJ: 1
3. Which condition is not diagnosed through clinical appearance?
a. Mandibular tori
b. Fordyce granules
c. Black hairy tongue
d. Compound odontoma
Answer: 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.
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.
Answer: 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.
REF: Geographic Tongue, page 24 OBJ: 7
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
Answer: 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
, 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.
Answer: 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.
REF: Leukoedema, page 23 OBJ: 8
7. Which condition most likely responds to therapeutic diagnosis?
a. Angular cheilitis
b. Amelogenesis imperfecta
c. Paget disease
d. Stafne bone cyst
Answer: 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
8. 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
