Dental OSCE (Objective Structured Clinical Examination) Practice Exam

What is a common side effect of dry mouth in denture wearers?

1. Increased tooth sensitivity

2. Difficulty in adjusting to the dentures

3. Enhanced taste perception

4. Improved oral hygiene

The correct answer is: Difficulty in adjusting to the dentures

In denture wearers, dry mouth, or xerostomia, is a common condition that can significantly impact their experience with dentures. One notable side effect of dry mouth is difficulty in adjusting to the dentures. Saliva plays a critical role in maintaining dental arch stability and comfort when wearing dentures. It helps to lubricate the oral cavity and aids in the retention and stability of the dentures. When a person has dry mouth, the lack of adequate saliva can lead to increased friction, discomfort, and irritability of the oral tissues, making it challenging for the person to adapt to their dentures. This can result in sore spots and difficulty in properly sealing the dentures, leading to an inconsistent fit and an uncomfortable experience overall as they try to eat and speak. Other options would not be typical outcomes related to dry mouth in denture wearers. Enhanced taste perception and improved oral hygiene do not correspond to xerostomia among denture users. Increased tooth sensitivity is generally associated with other factors rather than with the wearing of dentures and dry mouth. Understanding the relationship between dry mouth and denture adaptation is crucial for providing comprehensive care to patients experiencing this condition.
