A patient has HIV, type II diabetes, hepatitis B and C, and asthma. Which condition would NOT be expected to increase the patient's risk of dental caries?

Correct answer: B. Type II diabetes

• A. HIV (and its medications) frequently cause xerostomia and candidiasis, raising caries risk.
• B. Correct (keyed). Of the choices, type II diabetes is most directly linked to PERIODONTAL disease rather than caries; the document treats it as the answer least tied to caries risk. (Note: poorly controlled diabetes with hyposalivation can still raise caries risk.)
• C. A high-sugar diet is the most direct dietary driver of caries — clearly increases risk.
• D. Asthma inhalers (beta-agonists, dry-powder steroids) reduce salivary flow and lower oral pH, increasing caries risk.

Note: Phrasing is awkward. Clinically, diabetes affects periodontium more than caries, which is why it is keyed here; but uncontrolled diabetes can still raise caries risk through xerostomia.
