ff ff ff ff ff ff ff


a. Mandibular tori ff


b. Fordyce granules ff


c. Black hairy tongue ff ff


d. Compound odontoma ff




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


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


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

Fordyce granules are yellow clusters of ectopic sebaceous glands diagnosed

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


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

, a. median rhomboid glossitis. ff ff


b. benign migratory glossitis. ff ff


c. fissured tongue. ff


d. black hairy tongue. ff ff




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


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


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


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


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


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


become elongated and are dark brown to black.

Which condition is suspected?
ff ff ff ff


a. Palatal cyst ff


b. Torus palatinus ff


c. Mixed tumor ff


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


palate. Diagnosis is made on the basis of clinical appearance. A palatal cyst appears
ff f f ff ff ff ff ff ff ff ff ff ff ff ff


radiolucent on a radiographic examination and is not diagnosed through clinical
ff ff f f ff ff ff ff ff ff ff ff


appearance. A mixed tumor orpleomorphic adenoma is a benign tumor of salivary
ff f f ff ff ff ff ff ff ff ff ff


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


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


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

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


ff variant of normal that requires no treatment and is termed
uu ff ff ff ff ff ff ff ff


a. linea alba. ff


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




ANS: f f B
Leukoedema is a diffuse opalescence most commonly seen on the buccal mucosa in black
ff ff ff ff ff ff ff ff ff ff ff ff ff


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


mucosa along the occlusal plane. It is most prominent in patients who have a clenching
ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff


or grinding habit. Leukoplakia is a clinical term for a white lesion, the cause of which is
ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff


unknown. Whitesponge nevus is a genetic (autosomal dominant) trait. Clinically, it is
ff ff ff ff ff ff ff ff ff ff ff ff


characterized by a soft white, folded (or corrugated) oral mucosa. Athick layer of keratin
ff ff ff ff ff ff ff ff ff ff f ff ff ff


produces the whitening.

ff ff ff ff ff ff ff


a. Angular cheilitis ff


b. Amelogenesis imperfecta ff


c. Paget disease ff


d. Stafne bone cyst ff ff




ANS: f f A
Angular cheilitis most commonly responds to antifungal therapy once nutritional
ff ff ff ff ff ff ff ff ff


deficiencies have been ruled out.Amelogenesis imperfecta is a genetic condition
f f ff ff ff ff f ff ff ff ff ff


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


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


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


diagnosis in which entrapped salivary gland tissue is identified.

blocker. Which medication is the likely cause?
ff ff u ff ff ff ff


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


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


Clozapine is an antipsychotic used in the management of psychotic symptoms in

ANS: f f A
Paget disease is a chronic metabolic bone disease. Radiographically, cotton-wool
ff ff ff ff ff ff ff ff ff


radiopacities and hypercementosis are characteristic features. Dentinogenesis imperfecta is
ff u ff ff ff ff ff ff ff


a genetic condition involving a defect in the development of dentin. Anemia, a

decrease in red blood cells, requires blood tests to determine the etiologic factors.
