Non-emergency prophylaxis should be postponed in the presence of which condition?

• A. Acute systemic illness
• B. Controlled chronic disease
• C. Allergic to penicillin with no symptoms
• D. Recent dental cleaning last week

Answer: (A)

The key idea is that elective dental prophylaxis should wait if the patient is currently fighting an acute systemic illness. When the body is already dealing with fever, malaise, or a systemic infection, adding the stress of a dental procedure can worsen the illness or lead to more complications. Once the acute illness resolves, prophylaxis can be reconsidered.

Being able to control a chronic disease does not by itself require postponing care, since stability means the body can typically handle the procedure. Having a penicillin allergy with no symptoms also doesn’t justify delaying prophylaxis; allergy history informs antibiotic choice, but it isn’t a reason to defer treatment unless the allergy is active or severe. A recent dental cleaning last week isn’t a contraindication either, so it wouldn’t be a reason to postpone.
