Sample itemWhich description best fits a typical minor aphthous ulcer?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Painful shallow ulcer with an erythematous halo on nonkeratinized mucosa
Minor aphthous ulcers are usually painful, shallow, round or oval ulcers with a red halo on nonkeratinized oral mucosa and tend to heal spontaneously within one to two weeks.
Option by option
A. Painful shallow ulcer with an erythematous halo on nonkeratinized mucosa (correct)
Correct: this painful shallow haloed lesion fits minor aphthous ulceration.
B. A diffuse black coating from calculus
Calculus is mineralized plaque rather than an ulcerative lesion.
C. Painless hard mass fixed to bone
A fixed hard mass warrants assessment for a different serious process.
D. A vesicle limited to the lip border only
Lip-border vesicles are more typical of herpes labialis.
