Dental OSCE (Objective Structured Clinical Examination) Practice Exam

When treating increased interocclusal space associated with Chelitis, what is typically recommended?

1. Decrease this space by increasing vertical dimension of occlusion (VDO)

2. Increase this space by decreasing VDO

3. Maintain VDO and monitor closely

4. Implement dietary changes only

The correct answer is: Decrease this space by increasing vertical dimension of occlusion (VDO)

In cases of increased interocclusal space associated with cheilitis, the common recommendation is to decrease this space by increasing the vertical dimension of occlusion (VDO). This is typically carried out to restore proper occlusal relationships and improve function. When there is an increased interocclusal space, it indicates that the teeth are not making contact as intended, which can lead to functional problems, discomfort, and aesthetic issues. By increasing the VDO, one is effectively bringing the occlusal surfaces of the teeth closer together, which can lead to better contact points and a more stable bite. This adjustment can alleviate some of the problems related to cheilitis, such as excessive tension or strain on the musculature around the lips and mouth that could be exacerbated by inadequate occlusal relationships. Maintaining VDO and monitoring closely might suggest a more conservative or passive approach, which could be appropriate in some situations, but in cases where interocclusal space is significantly compromised, active intervention to restore balance is often necessary. Dietary changes may benefit oral health in a broader context but will not directly address the mechanical aspect of the occlusion that is affecting the cheilitis.
