Which type of pulp tissue is of particular concern because it may respond differently to liners and cements?

• A. Inflamed
• B. Healthy
• C. Necrotic
• D. Hyperplastic

Answer: (A)

Inflamed pulp tissue is especially concerning because inflammation changes how the pulp responds to materials. The inflamed pulp has increased blood flow, inflammatory mediators, and altered cellular activity, which can make it more susceptible to irritation from liners and cements and less capable of healing or forming a protective dentin barrier. Materials that are relatively inert with healthy pulp may provoke more discomfort or further tissue damage in an inflamed pulp, so the choice of liner or cement is especially critical to minimize irritation and preserve vitality. In contrast, healthy pulp tolerates these materials more predictably, necrotic pulp cannot mount a healing response, and hyperplastic pulp involves a proliferative inflammatory change with different considerations, but the immediate material response concern centers on the inflamed state.
