Choose correct properties of zinc oxide eugenol cements:
- A. average mechanical strength, pH within range of 7, good thermal and electrical isolation.
- B. antifungal and anaesthetic activity, low solubility in water, moderate harmfulness towards pulp cells.
- C. ability to stimulate the secondary, but not reparative, dentin layering, antifungal and anaesthetic activity.
- D. good enamel and dentin adhesion, long-term cavity persistence, low solubility in water.
- E. causing discoloration in mineralized tooth tissues, especially after repeated insertion to the cavity, good enamel and dentin adhesion, low solubility in water.
Hint
Eugenol soothes the pulp and kills microbes but irritates on direct contact; the cement itself is weak, soluble and non-adhesive.
