Fordyce granules are yellow clusters of ectopic sebaceous glands diagnosed through clinical
y, y, y, y, y, y, y, y, y, y, y, y,




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

ANS: B y ,




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




median rhomboid glossitis is associated with a chronic fungal infection from Candida albicans.
y, y, y, y, y, y, y, y, y, y, y, y, y,




Sometimes the condition resolves with antifungal therapy. Fissured tongue is seen in5% of the
y, y, y, y, y, y, y, y, y, y, y, y, y, y, y,




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




Black hairy tongue is caused by a reaction to chemicals, tobacco, hydrogen peroxide, or
y, y, y, y, y, y, y, y, y, y, y, y, y, y,




antacids. The filiform papillae on the dorsal tongue become elongated and are dark brown to

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

orpleomorphic adenoma is a benign tumor of salivary gland origin, found unilaterally off the
y, y, y, y, y, y, y, y, y, y, y, y, y, y, y,

ANS: B y ,




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




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

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

Leukoplakia is a clinical term for a white lesion, the cause of which is unknown. Whitesponge

Angular cheilitis most commonly responds to antifungal therapy once nutritional deficiencies

have been ruled out. Amelogenesis imperfecta is a genetic condition associated with
