How do anti-BP drugs affect denture wearers?

1. Increase the retention of dentures

2. Enhance saliva production

3. Decrease retention by inducing dry mouth

4. Have no significant effect on denture wearers

The correct answer is: Decrease retention by inducing dry mouth

Anti-hypertensive medications, often referred to as anti-BP drugs, are known to have side effects that can impact oral health, particularly dry mouth or xerostomia. This condition arises because several of these medications can reduce saliva production. Saliva is a crucial factor for the maintenance and retention of dentures since it aids in creating the necessary suction to keep dentures securely in place. When saliva levels decrease, denture wearers may experience increased discomfort and challenges with retention. With less saliva, the mucosal surfaces become drier, leading to a compromised fit of the dentures and making it difficult for patients to maintain a stable hold. Inadequate saliva also contributes to difficulties in chewing and swallowing, further hindering the overall experience of wearing dentures. The other options do not accurately represent the effects of anti-BP medications. They do not typically increase retention or enhance saliva production; in fact, the opposite is true. While there may not be a total lack of effect on some patients, the overall trend indicates a significant impact due to dry mouth, making it the most relevant concern for denture wearers.
