Which interventions are recommended to prevent oral candidiasis in patients with mucositis?

• A. Poor oral hygiene with rancid or irritating foods
• B. Regular use of broad-spectrum antibiotics prophylaxis
• C. Rinsing with plain water only
• D. Good oral hygiene, antifungal therapy if indicated, and avoidance of rancid or irritating foods

Answer: (D)

Maintaining the integrity of the oral environment is key when mucositis is present, because damaged mucosa and shifts in the oral flora increase the risk of Candida overgrowth. Good oral hygiene helps reduce dental plaque and microbial load, lowering the opportunity for Candida to colonize. If there are risk factors or signs of infection, antifungal therapy should be used to prevent progression, rather than waiting for full-blown candidiasis. Avoiding rancid or irritating foods minimizes mucosal irritation and inflammation that can promote fungal growth. Routine broad-spectrum antibiotics can disrupt normal flora and aren’t a preventive strategy for candidiasis, and rinsing with plain water alone doesn’t adequately control microbial load or protect the mucosa.
