What is a primary cause of residual ridge erythema in patients wearing removable partial dentures?

• A. Overextended major connector
• B. Pressure area in tissue surface of denture base
• C. Occlusal disharmony
• D. Poorly contoured denture base

Answer: (B)

Residual ridge erythema in patients wearing removable partial dentures is primarily caused by pressure areas that develop on the tissue surface of the denture base. When a removable partial denture exerts excessive force or pressure on specific areas of the oral mucosa, it can lead to localized inflammation, resulting in erythema. This condition often arises when the denture does not fit properly, allowing certain parts of the denture to create areas of unequal pressure. The inflammation can cause discomfort and sensitivity, which further underscores the importance of achieving a well-fitting denture. Managing pressure points during the fabrication and adjustment of dentures is crucial to prevent this condition from arising and to promote overall oral health for the patient. Understanding the relationship between the fit of the denture and the health of the oral tissues helps practitioners address and alleviate issues like residual ridge erythema, ensuring patients can wear their dentures comfortably and without complications.
