Zinc phosphate cement is known for which property?

Zinc phosphate cement stands out for its high strength as a permanent luting cement, and its liquid component contains phosphoric acid, which can irritate the dental pulp if dentin is thin or the preparation is close to the pulp. This acidity is why there is caution with its use near the pulp, even though it provides excellent long-term strength for cementing crowns and similar restorations. It is not chosen for temporary work (other cements are used for that), and it is not considered non-irritating to pulp. The idea that it’s easily removed is not accurate, as its set material can be quite hard and cleanup requires effort.
