What is the main cause of gingivitis in partial-denture patients?

• A. Placement of dentures
• B. Patient's oral hygiene habits
• C. Plaque accumulation
• D. Allergic reactions to materials

Answer: (C)

The main cause of gingivitis in partial-denture patients is plaque accumulation. When patients have partial dentures, there are additional surfaces and areas within the mouth where plaque can develop, especially if the dentures do not fit properly. This can lead to bacteria being trapped around the gums and teeth, which increases the risk of inflammation and gingivitis.

Effective oral hygiene practices become crucial for partial-denture wearers because the presence of the denture adds complexity to maintaining a clean oral environment. If plaque is not regularly removed through proper brushing and flossing, it can lead to the inflammation of the gums, commonly referred to as gingivitis. Thus, the control of plaque through consistent and effective oral hygiene is vital for preventing gum disease in patients with dentures.
