What is defined as a complex cavity?

1. Cavity involving a single surface of a tooth

2. Cavity that is temporary

3. Decay involving more than two surfaces of a tooth

4. Cavity that is easily repaired

The correct answer is: Decay involving more than two surfaces of a tooth

A complex cavity is characterized by decay that affects more than two surfaces of a tooth. This complexity typically indicates a more advanced stage of decay that requires a more intricate and detailed approach for restoration. In dental terminology, when a cavity involves multiple surfaces—such as the mesial, distal, buccal, or lingual surfaces—it can complicate the treatment plan since it may involve more extensive removal of decayed material and potentially more restorative work to ensure the tooth maintains its structure and function. Options describing a cavity involving a single surface or those that are temporary or easily repaired do not reflect the definition of a complex cavity. Single-surface cavities are simpler and often require less intervention, while temporary cavities imply a temporary solution that doesn’t address the complexity of decay affecting more than two surfaces. Similarly, the notion of easily repaired cavities suggests a lack of complexity and a straightforward dental procedure, which contrasts with the robust intervention required for complex cavities that involve significant decay across multiple tooth surfaces.
