Which dental material is commonly used for base and liner applications?

Zinc oxide eugenol is frequently used as a dental material for base and liner applications due to its unique properties that make it ideal for these specific uses in restorative dentistry. It exhibits excellent thermal insulating qualities, which helps protect the pulp in deep cavities from temperature changes that could cause discomfort or damage.

Additionally, zinc oxide eugenol has a soothing effect on the dental pulp due to the presence of eugenol, which also possesses antimicrobial properties. This can contribute to a reduced risk of pulpitis in cases where it is used as a liner under restorative materials.

Zinc oxide eugenol is also easy to manipulate and can be used both as a base under restorations and as a liner in deeper cavity preparations, making it a versatile choice for dental procedures that require protection of the underlying tooth structure.

Given these advantages, it is clear why zinc oxide eugenol is a preferred choice for base and liner applications in restorative dental work.
