Dental OSCE (Objective Structured Clinical Examination) Practice Exam

What long-term reaction can occur from wearing ill-fitting dentures?

1. Bone resorption

2. Epulis

3. Papillary hyperplasia

4. Both Epulis and Papillary hyperplasia

The correct answer is: Both Epulis and Papillary hyperplasia

Wearing ill-fitting dentures can lead to several complications in the oral cavity, particularly as the situation persists over time. One significant long-term reaction is bone resorption, which occurs when the underlying bone loses its integrity and density, often due to pressure and lack of stimulation that should normally occur with functional teeth. However, more specifically related to the options provided, both epulis and papillary hyperplasia can develop as a direct consequence of ill-fitting dentures. Epulis refers to a benign growth on the gum tissue, which can occur due to chronic irritation from the denture base. This irritation can be exacerbated by the friction and pressure on the tissue, leading to localized hyperplastic changes where the gum tissue enlarges in response to the constant stimulus. Papillary hyperplasia is another condition that can arise due to the presence of dentures. This condition typically manifests as the proliferation of tissue characterized by a cobblestone appearance on the hard palate and is commonly associated with poor-fitting dentures that cause irritation, coupled with poor oral hygiene. Therefore, the correct answer reflects the fact that both epulis and papillary hyperplasia are potential reactions resulting from wearing ill-fitting dentures, emphasizing the importance of proper denture fit and maintenance for oral health.
