What factor may lead to denture stomatitis and irritation of palatal tissues?

• A. Continuous denture wear
• B. Use of denture adhesive
• C. Regular dental checkups
• D. Adequate saliva

Answer: (A)

Continuous denture wear keeps the mucosa under constant coverage, preventing tissue rest and cleansing. The palatal tissues are exposed to persistent pressure and friction from the denture, which causes microtrauma and inflammation. In this warm, moist, low-oxygen environment, Candida species can overgrow, leading to denture stomatitis and irritation of the palatal tissues. Removing dentures periodically allows tissue recovery, improves airflow, and lets saliva help cleanse and protect the mucosa, reducing risk. While denture adhesive can affect retention, it does not inherently cause stomatitis when used properly. Regular dental checkups and adequate saliva aid in maintaining fit, hygiene, lubrication, and antimicrobial protection, making them protective factors rather than causes.
