Dental OSCE (Objective Structured Clinical Examination) Practice Exam

Which complication is commonly seen after the insertion of a crown?

1. Prolonged sensitivity

2. Working or non-working interference

3. Crown fracture

4. Decay at margins

The correct answer is: Working or non-working interference

The most commonly seen complication after the insertion of a crown is prolonged sensitivity. This sensitivity can arise due to several factors, including pulp irritation during the tooth preparation process, the presence of underlying dental conditions such as decay or trauma, or the materials used in the crown itself. When a crown is placed, it can sometimes cause temperature changes and pressure on the underlying dentin and pulp, leading to discomfort that may last for weeks or even months. Working or non-working interference relates more to occlusal issues that can develop after the insertion of the crown, affecting how the upper and lower teeth align and function together. While crown fracture can occur, it is less common and is typically a result of unforeseen factors like trauma or excessive occlusal forces. Decay at the margins is also a potential long-term risk, particularly if there is inadequate sealing or proper oral hygiene post-cementation, but this tends to be a more delayed complication rather than an immediate one after insertion. In summary, prolonged sensitivity is a frequent and immediate complication that can arise after crown insertion, affecting patient comfort and sometimes requiring additional intervention to manage the symptoms effectively.
