ANS: D f
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
f f f f f f f f f f f f f
clinically as areas of exostosis on the lingual aspects of mandibular premolars. Fordyce
f f f f f f f f f f f f f
granules are yellow clusters of ectopic sebaceous glands diagnosed through clinical
f f f f f f f f f f f
appearance. Black hairy tongue is diagnosed clinically. The filiform papillae on the dorsal
f f f f f f f f f f f f f
tongue elongate and become brown or black. Causes include tobacco, alcohol, hydrogen
f f f f f f f f f f f f
peroxide, chemical rinses, antibiotics, and antacids.

Benign migratory glossitis is another name for geographic tongue. Research suggests that
f f f f f f f f f f f
median rhomboid glossitis is associated with a chronic fungal infection from Candida albicans.
f f f f f f f f f f f f f
Sometimes the condition resolves with antifungal therapy. Fissured tongue is seen in5% of the

population. It is a variant of normal. Genetic factors are typically associated with the condition.
f f f f f f f f f f f f f f f
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

ANS: B f
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
f f f f f f f f f f f f f
pleomorphic adenoma is a benign tumor of salivary gland origin, found unilaterally off the
f f f f f f f f f f f f f f
midline of the hard palate. It is composed of tumor tissue that is not bony hard to palpation.

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