How does HCTZ potentially affect retention in denture patients?

• A. Increases retention
• B. Decreases retention due to less salivation
• C. Does not affect retention
• D. Causes over-retention

Answer: (B)

Hydrochlorothiazide (HCTZ) is a thiazide diuretic commonly used to treat conditions like hypertension and edema. One of the side effects of HCTZ is its potential to reduce saliva production. Saliva is essential for the retention of dentures, as it provides a critical adhesive quality that helps keep the denture in place. When salivary flow decreases, the ability of the denture to create suction and adhere to the mucosal surfaces in the mouth diminishes, leading to difficulties in retention. This decreased salivation can make it more challenging for patients to maintain their dentures comfortably, thus impacting their overall experience and effectiveness of the dentures. In contrast, other options do not accurately capture the role of HCTZ in salivation and denture retention. For instance, stating it increases retention ignores the fundamental relationship between salivary flow and denture stability. Claiming it does not affect retention overlooks the well-documented side effect of reduced saliva production. Meanwhile, the idea that it causes over-retention would be incorrect, as increased saliva typically aids retention rather than diminishes it. Therefore, the assertion that HCTZ decreases retention due to less salivation reflects the clinically recognized ramifications of the medication on oral health
