What is the most common etiology of denture stomatitis?

• A. Continuous denture wear
• B. Allergic reaction to acrylic
• C. Poor dental hygiene alone
• D. Bacterial plaque only

Answer: (A)

Continuous denture wear is the main driver of denture stomatitis. When a denture is worn constantly, the mucosa beneath it is kept in a warm, moist, and occluded environment, which favors the growth of Candida species and the formation of a biofilm on the denture base. This persistent irritation and fungal colonization lead to the inflammatory changes seen under the denture, often with a red, inflamed appearance in the palate and along the denture-bearing tissues. While poor hygiene and plaque accumulation can contribute, they do not explain the fungal involvement and the pattern of inflammation as effectively as prolonged, uninterrupted denture wear. Allergic reactions to acrylic are relatively uncommon triggers, and attributing denture stomatitis to bacterial plaque alone omits the crucial role of Candida in the condition. To help prevent it, denture wear should be minimized—especially overnight—and combined with thorough cleaning and proper fit.
