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


which tooth structure can be identified. No clinical component exists. Mandibular tori
ss uu ss ss ss ss ss ss ss ss ss ss


are identified clinically as areas of exostosis on the lingual aspects of mandibular

premolars. Fordyce granules are yellow clusters of ectopic sebaceous glands

filiform papillae on the dorsal tongue elongate and become brown or black. Causes

include tobacco, alcohol, hydrogen peroxide, chemical rinses, antibiotics, and antacids.

b. benign migratory glossitis. ss ss


c. fissured tongue. ss


d. black hairy tongue. ss ss




ANS: s s B
Benign migratory glossitis is another name for geographic tongue. Research suggests that
ss ss ss ss ss ss ss ss ss ss ss


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


albicans. Sometimes the condition resolves with antifungal therapy. Fissured tongue is
ss ss ss ss ss ss ss ss ss ss ss


seen in 5% of the population. It is a variant of normal. Genetic factors are typically
ss ss uu ss ss ss ss ss ss ss ss ss ss ss ss ss


associated with the condition. Black hairy tongue is caused by a reaction to chemicals,
ss ss ss ss ss ss ss ss ss ss ss ss ss ss


tobacco, hydrogen peroxide, or antacids. The filiform papillae on the dorsal tongue
ss ss ss ss ss ss ss ss ss ss ss ss


become elongated and are dark brown to black.

5. This bony hard structure in the midline of the hard palate is genetic in origin and
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss


inherited in an autosomal dominant manner. The diagnosis is made through clinical
ss s s uu ss ss ss ss ss ss ss ss ss


appearance. Which condition is suspected?
ss ss ss ss ss


a. Palatal cyst ss


b. Torus palatinus ss


c. Mixed tumor ss


d. Ranula
ANS: s s B
A torus palatinus is developmental and bony hard and is found on the midline of the
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss


palate. Diagnosis is made on the basis of clinical appearance. A palatal cyst appears
ss s s ss ss ss ss ss ss ss ss ss ss ss ss


radiolucent on
ss a radiographic examination and is not diagnosed through
ss s s ss ss ss ss ss ss ss


clinical appearance. A mixed tumor orpleomorphic adenoma is a benign tumor of
ss ss ss ss ss ss ss ss ss ss ss ss


salivary gland origin, found unilaterally off the midline of the hard palate. It is
ss ss ss ss ss ss ss ss ss ss ss ss ss ss


composed of tumor tissue that is not bony hard to palpation.
ss ss ss ss ss ss ss ss ss ss ss


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

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


ss a variant of normal that requires no treatment and is termed
ss uu ss ss ss ss ss ss ss ss


a. linea alba. ss


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




ANS: s s B
Leukoedema is a diffuse opalescence most commonly seen on the buccal mucosa in
ss ss ss ss ss ss ss ss ss ss ss ss


black individuals. Linea alba is a ―white line‖ that extends anteroposteriorly on the
ss ss ss ss ss ss ss ss ss ss ss ss ss


buccal mucosa along the occlusal plane. It is most prominent in patients who have a
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss


clenching or grinding habit. Leukoplakia is a clinical term for a white lesion, the cause
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss


of which is unknown. Whitesponge nevus is a genetic (autosomal dominant) trait.
ss ss ss ss ss ss ss ss ss ss ss ss


Clinically, it is characterized by a soft white, folded (or corrugated) oral mucosa. Athick
ss ss ss ss ss ss ss ss ss ss ss ss ss ss


layer of keratin produces the whitening.

ss ss ss ss ss ss ss


a. Angular cheilitis ss


b. Amelogenesis imperfecta ss


c. Paget disease ss


d. Stafne bone cyst ss ss




ANS: s s A
Angular cheilitis most commonly responds to antifungal therapy once nutritional
ss ss ss ss ss ss ss ss ss


deficiencies have been ruled out.Amelogenesis imperfecta is a genetic condition
s s ss ss ss ss s ss ss ss ss ss


associated with abnormal development of the enamel. Paget disease is a chronic
ss ss ss u ss ss ss ss ss ss ss ss


metabolic bone disease. A highly elevated serum alkaline phosphatase level contributes
ss ss ss ss ss ss ss ss ss ss ss


significantly to the diagnosis. A Stafne bone cyst is determined through surgical
ss ss ss ss ss ss ss ss ss ss ss ss


diagnosis in which entrapped salivary gland tissue is identified.

c. Quinidine
d. Clozapine
ANS: s s B
Nifedipine is a calcium channel blocker. Dilantin is an anticonvulsant used to prevent
ss ss ss ss ss ss ss ss ss ss ss ss


orcontrol seizures. Quinidine is an antiarrhythmic agent used to treat cardiac
ss ss ss ss ss ss ss ss ss ss ss


arrhythmias. Clozapine is an antipsychotic used in the management of psychotic

Paget disease is a chronic metabolic bone disease. Radiographically, cotton-wool

radiopacities and hypercementosis are characteristic features. Dentinogenesis imperfecta
