ANS: D uu
The compound odontoma is initially identified radiographically as a radiopaque area in

whichtooth structure can be identified. No clinical component exists. Mandibular tori are
uu u uu uu uu uu uu uu uu uu uu uu uu
identified clinically as areas of exostosis on the lingual aspects of mandibular premolars.
uu uu uu uu uu uu uu uu uu uu uu uu uu
Fordyce granules are yellow clusters of ectopic sebaceous glands diagnosed through
uu uu uu uu uu uu uu uu uu uu uu
clinical appearance. Black hairy tongue is diagnosed clinically. The filiform papillae on the
uu uu uu uu uu uu uu uu uu uu uu uu uu
dorsal tongue elongate and become brown or black. Causes include tobacco, alcohol,
uu uu uu uu uu uu uu uu uu uu uu uu
hydrogen peroxide, chemical rinses, antibiotics, and antacids.

, a. median rhomboid glossitis. uu uu
b. benign migratory glossitis. uu uu
c. fissured tongue. uu
d. black hairy tongue. uu uu
ANS: B uu
Benign migratory glossitis is another name for geographic tongue. Research suggests that
uu uu uu uu uu uu uu uu uu uu uu
median rhomboid glossitis is associated with a chronic fungal infection from Candida
uu uu uu uu uu uu uu uu uu uu uu uu
albicans. Sometimes the condition resolves with antifungal therapy. Fissured tongue is seen
uu uu uu uu uu uu uu uu uu uu uu uu
in5% of the population. It is a variant of normal. Genetic factors are typically associated
uu u uu uu uu uu uu uu uu uu uu uu uu uu uu uu
with the condition. Black hairy tongue is caused by a reaction to chemicals, tobacco,
uu uu uu uu uu uu uu uu uu uu uu uu uu uu
hydrogen peroxide, or antacids. The filiform papillae on the dorsal tongue become
uu uu uu uu uu uu uu uu uu uu uu uu
elongated and are dark brown to black.

uu u uu uu uu uu uu uu uu uu uu uu
Which condition is suspected?
uu uu uu uu
a. Palatal cyst uu
b. Torus palatinus uu
c. Mixed tumor uu
d. Ranula
ANS: B uu
A torus palatinus is developmental and bony hard and is found on the midline of the palate.
uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu
Diagnosis is made on the basis of clinical appearance. A palatal cyst appears radiolucent on
uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu
a radiographic examination and is not diagnosed through clinical appearance. A mixed
uu uu uu uu uu uu uu uu uu uu uu uu
tumor orpleomorphic adenoma is a benign tumor of salivary gland origin, found
uu uu u uu uu uu uu uu uu uu uu uu uu
unilaterally off the midline of the hard palate. It is composed of tumor tissue that is not
uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu
bony hard to palpation.

6. The gray-white opalescent film seen on the buccal mucosa of 85% of black adults is a

u uu uu uu uu uu uu uu uu
a. linea alba. uu
b. leukoedema.
c. leukoplakia.
d. white sponge nevus. uu uu
ANS: B uu
Leukoedema is a diffuse opalescence most commonly seen on the buccal mucosa in black
uu uu uu uu uu uu uu uu uu uu uu uu uu
individuals. Linea alba is a ―white line‖ that extends anteroposteriorly on the buccal
uu uu uu uu uu uu uu uu uu uu uu uu uu
mucosa along the occlusal plane. It is most prominent in patients who have a clenching or
uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu
grinding habit. Leukoplakia is a clinical term for a white lesion, the cause of which is
uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu
unknown. Whitesponge nevus is a genetic (autosomal dominant) trait. Clinically, it is
uu uu u uu uu uu uu uu uu uu uu uu uu
characterized by a soft white, folded (or corrugated) oral mucosa. A thick layer of keratin
uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu
produces the whitening.

uu uu uu uu uu uu uu
a. Angular cheilitis uu

c. Paget disease uu
d. Stafne bone cyst uu uu
ANS: A uu
Angular cheilitis most commonly responds to antifungal therapy once nutritional
uu uu uu uu uu uu uu uu uu
deficiencies have been ruled out. Amelogenesis imperfecta is a genetic condition associated
uu uu uu uu uu uu uu uu uu uu uu uu
with abnormaldevelopment of the enamel. Paget disease is a chronic metabolic bone
uu uu u uu uu uu uu uu uu uu uu uu uu
disease. A highly elevated serum alkaline phosphatase level contributes significantly to the
uu uu uu uu uu uu uu uu uu uu uu uu
diagnosis. A Stafne bone cyst is determined through surgical diagnosis in which entrapped
uu uu uu uu uu uu uu uu uu uu uu uu uu
salivary gland tissue isidentified.

c. Quinidine
d. Clozapine
ANS: B uu
Nifedipine is a calcium channel blocker. Dilantin is an anticonvulsant used to prevent
uu uu uu uu uu uu uu uu uu uu uu uu
orcontrol seizures. Quinidine is an antiarrhythmic agent used to treat cardiac arrhythmias.
uu u uu uu uu uu uu uu uu uu uu uu uu

ANS: A uu
Paget disease is a chronic metabolic bone disease. Radiographically, cotton-wool
uu uu uu uu uu uu uu uu uu
radiopacitiesand hypercementosis are characteristic features. Dentinogenesis imperfecta is a
uu u uu uu uu uu uu uu uu uu
genetic condition involving a defect in the development of dentin. Anemia, a decrease in
uu uu uu uu uu uu uu uu uu uu uu uu uu uu
red blood cells, requires blood tests to determine the etiologic factors. Diabetes is a chronic
uu uu uu uu uu uu uu uu uu uu uu uu uu uu uu
disorder of carbohydrate metabolism characterized by abnormally high blood glucose

levels.
