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
g g g g g g g g g g g g g g g g g


lesion that contains serous fluid. Pustules are circumscribed elevations containing pus.

3. Which condition is not diagnosed through clinical appearance?
g g g g g g g


a. Mandibular tori g


b. Fordyce granules g


c. Black hairy tongue g g


d. Compound odontoma g




ANS: D g


The compound odontoma is initially identified radiographically as a radiopaque area in which
g g g g g g g g g g g g


tooth structure can be identified. No clinical component exists. Mandibular tori are identified
g g g g g g g g g g g g g


clinically as areas of exostosis on the lingual aspects of mandibular premolars. Fordyce
g g g g g g g g g g g g g


granules are yellow clusters of ectopic sebaceous glands diagnosed through clinical
g g g g g g g g g g g


appearance. Black hairy tongue is diagnosed clinically. The filiform papillae on the dorsal
g g g g g g g g g g g g g


tongue elongate and become brown or black. Causes include tobacco, alcohol, hydrogen
g g g g g g g g g g g g


peroxide, chemical rinses, antibiotics, and antacids.

a. median rhomboid glossitis. g g


b. benign migratory glossitis. g g


c. fissured tongue. g


d. black hairy tongue. g g




ANS: B g


Benign migratory glossitis is another name for geographic tongue. Research suggests that
g g g g g g g g g g g


median rhomboid glossitis is associated with a chronic fungal infection from Candida
g g g g g g g g g g g g


albicans. Sometimes the condition resolves with antifungal therapy. Fissured tongue is seen in
g g g g g g g g g g g g g


5% of the population. It is a variant of normal. Genetic factors are typically associated with
g g g g g g g g g g g g g g g g


the condition. Black hairy tongue is caused by a reaction to chemicals, tobacco, hydrogen
g g g g g g g g g g g g g g


peroxide, or antacids. The filiform papillae on the dorsal tongue become elongated and are
g g g g g g g g g g g g g g


dark brown to black.

gcondition is suspected? g g

a. Palatal cyst g


b. Torus palatinus g


c. Mixed tumor g


d. Ranula
ANS: B g


A torus palatinus is developmental and bony hard and is found on the midline of the palate.
g g g g g g g g g g g g g g g g


Diagnosis is made on the basis of clinical appearance. A palatal cyst appears radiolucent on a
g g g g g g g g g g g g g g g g


radiographic examination and is not diagnosed through clinical appearance. A mixed tumor or
g g g g g g g g g g g g g


pleomorphic adenoma is a benign tumor of salivary gland origin, found unilaterally off the
g g g g g g g g g g g g g g


midline of the hard palate. It is composed of tumor tissue that is not bony hard to palpation.
g g g g g g g g g g g g g g g g g g


Ranula is a term used for a mucocele-like lesion that forms unilaterally on the floor of the
g g g g g g g g g g g g g g g g


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
g g g g g g g g


a. linea alba. g


b. leukoedema.
c. leukoplakia.
d. white sponge nevus. g g




ANS: B g


Leukoedema is a diffuse opalescence most commonly seen on the buccal mucosa in black
g g g g g g g g g g g g g


individuals. Linea alba is a ―white line‖ that extends anteroposteriorly on the buccal mucosa
g g g g g g g g g g g g g


galong the occlusal plane. It is most prominent in patients who have a clenching or grinding
g g g g g g g g g g g g g g g


ghabit. Leukoplakia is a clinical term for a white lesion, the cause of which is unknown. White
g g g g g g g g g g g g g g g g


gsponge nevus is a genetic (autosomal dominant) trait. Clinically, it is characterized by a soft
g g g g g g g g g g g g g g


gwhite, folded (or corrugated) oral mucosa. A thick layer of keratin produces the whitening.

ANS: A g


Angular cheilitis most commonly responds to antifungal therapy once nutritional deficiencies
