Which factor does NOT predispose a pediatric patient to thrush?

• A. Poor oral hygiene
• B. Age
• C. Steroid therapy
• D. Antibiotics

Answer: (A)

Oral thrush happens when Candida albicans overgrows in the mouth because the usual defenses or bacterial balance are disrupted. In children, younger age means less mature oral defenses and saliva flow, which can make fungal colonization more likely. Inhaled steroids can suppress local immunity in the oropharynx, allowing Candida to proliferate. Antibiotics disrupt the normal bacterial flora that keep Candida in check, creating an ecological niche for the fungus to overgrow. Poor oral hygiene, while important for preventing bacterial dental issues, does not directly predispose to thrush because Candida is a common resident of the oral cavity and thrush more often results from immune immaturity or ecological disruption rather than cleaning habits.
